Davis FARS Upgrade to a Monitored PC Fan

Link to original Davis Fan Motor change

When the original Davis FARS motor failed I installed a new motor and kept back some spare motors, waiting for the inevitable motor failure to occur, reading online, changing from the Davis Fan to a PC varient made a lot of sense and not only is the life of motor excellent, but it is possible to monitor the motors output for operation.

I was interested to know the existing Davis fans air flow, mine was running at 2.4vDC and showed 9.7m/s:

The PC fan I bought was a Noctura NF-R8 redux -1800 PWM for £9.99 of eBay.

With the David FARS removed, the existing fan assembly slides out of the housing as a complete fan & surround, the hole left will take the 80 x 80mm fan with only a very minor filing of the fan case body to make it slide into the body of the FARS.

No modifications are made to the existing FARS body allowing reversion back to the existing fan if I wish (can’t think why, but you never know!).

To form a seal around the gaps, I used self adhesive door/window strip seal.

The finished fan after the seal is applied and checking that the fan is sucking, rather than blowing:

The oringinal fan ran on 2.4v, I replaced the voltage regulators fixed value resistor for the correct one to give 11.54vDC output and this feeds the motor and the motor monitoring Tacho.

The air flow of the PC fan when installed and connected was 5.5m/s, this is less than the original davis fan, but this is still better than static air within the sensing chamber.

The Davis weather station I have is the wired version, and I used Cat5e cable rather than the supplied 4 core cable from the ISS to the console, using the Cat5e unused cores, I fed the supply voltage to the fan and the Tacho pulse into the house where they are connected to a 52mm (2″) counter tachometer guage RPM, this was bought off eBay for £6.70 + £1.69 postage.

Tacho installed in the equipment cabinet:

The PC fan connections are:

  • Black – Negative 12v
  • Yellow – Positive 12v
  • Green – Tacho Pulse
  • Blue – PWM (Not Used)

The Tacho is set for a 4 cyclinder engine using a switch on the back of the unit, with the fan running the backlit RPM display is showing just under 1000RPM (reading slightly low due to voltage drop introducd by the distance from the ISS to the end point), to the left of the Tacho is my Meteobridge Pro  weather station server to the internet.

The motor is guaranteed for 6 years, replacement will be very easy and I’m able to remotley monitor that the fan is functioning, all for less than £20.

 

Shack/Office Refurbishment

Well what a job!!

My home office is also my shack and like most things, the infrastructure grew rather than was managed, so I knew the electrical power was not ideal and the network patch panel was full. The thing that brought it to a head was the need for a new floor covering, and so it began.

First job was to put in a new final circuit ring main to the office dado trunking and add a couple of additional power points for the UPS and mobile air conditioning unit.

As the cables are ran in the loft, I decided to install a decent fold down loft hatch and sliding ladder for ease of access, the loft lighting was also improved by installing 4 x 4′ fluorescent operated by a pull switch fed from its own dedicated circuit, this lighting made a huge difference.

To move everything out of the office to get access to the floor meant it needed to go somewhere, and the obvious choice was the loft, so off to Homebase for loft flooring and loft legs and of course it was boarded during the hottest days of July.

Once everything was out, I could start tearing down to rebuild:

The existing home network hub needed to come out:

MB Pro fitted

No going back now!

New cable drops for additional tap points near the TV and existing TalkTalk router are shown, I did move/rationalise other tap points around the house and in the garage. In the lounge I drilled through to the external wall and installed conduit in preparation for when Virgin Media install fibre to the home.

The network cables were in and tested using a cheap and cheerful wire mapper and did find a faulty tap point, so well worth £2.59.

Once the power was sorted out, it was time to start on the cabinet, this is a 12U wall mounted jobbie and cost £48.49 from eBay, the power distribution unit is fed via an 800VA MGE Pulsar Evolution UPS as is the red sockets.

Cables identified and marked up, rather than numbering the tap points, I opted to use a convention which accommodated change easily:

  • OFnn =Office, tap point nn
  • BD2/nn  = Bedroom 2, tap point nn
  • BD3/nn = Bedroom 3, tap point nn
  • LOnn = Loft,  tap point nn
  • Lnn = Lounge,  tap point nn
  • Gnn = Garage,  tap point nn
  • Hnn = Hall,  tap point nn

I, well me and my XYL took the opportunity to start to spruce the place up with a coat of paint as well. This shows the wall ready for the roller.

Wall cabinet finished, I added a small temperature controller which switches on the cabinet fan and the ceiling mounted fan within the cupboard where the cabinet is fitted.

Working top down:

  • 2U blank plate
  • Telephone line IN, OUT via ADSL filtered ports
  • Temperature controller
  • 24 port patch panel wired in Cat5e, two ports spare
  • Brush strip to hide surplus cable or manage surplus cable if your a purist
  • Netgear JGS524E Managed Gigabit switch
  • 1U blank plate (91/2″) (behind this is a 6 way PDU fed via UPS)
  • 1U 91/2″ Shelf with PoE to TP EAP245 Access Point
  • 1U 91/2″ Shelf with Metobridge Pro and EdgeRouter X
  • 19″ 350mm deep shelf

Bottom shelf from left to right:

  • Tach display for weather station aspirated sensor fan speed
  • Low noise linear 5v PSU for Blitzortung lighting detector
  • 12v PSU to Network Attached Storage (NAS) and CCTV interface
  • Netgear Duo 500Gb dual hard drive NAS
  • CCTV controller interface

 

Cabinet closed and locked after making sure it didn’t hit the ceiling light.

 

Room with everything put back in and tidied up.

To make life easier for working on the radio equipment cables and connections, I didn’t push the desk right back to the wall and also no radio related equipment is on the floor (PSU), apart from the foot operated PTT.

Radio wise I didn’t do much, I added a separate 12v PSU for auxiliary equipment, such as the led signage, VSWR panel lights and SG autotuner to name a few, I also added a common RF earth board for the shack equipment to connect to.

Radio all put back together and cables tidied up, not sure how long the office will stay this neat 🙂

Update

The cheap and cheerful cable tester unfortunately didn’t last the test of time and started giving some strange mapping indications, returning to eBay, I found a SC8108 Network Cable Tester for £17.98, this is superb value, and hopefully it will last longer than the last cable tester.

 

The SC8108 is very easy to use and has a number of useful, menu driven features, but for my small home network, wire mapping is the primary focus.

Davis 7346.174 – Pro2 Upgraded Digital Temperature Humidity Sensor

I decided to give the weather station a revamp, the two mini projects are the replacement of the Fan used to asperate the temperture/humidity sensor and the replacement of the original Davis temp/hum sensor with the more accurate chipset SHT15.

 

 

 

 

 

 

 

 

I bought the Davis 7346-174 upgrade from Scaled Instruments in Florida for $67.50 delivered (£51.94), the unit arrived very quickly as expected as I have used Scaled Instruments before and the service is exceptional.

Disassembly was quite straightforward after putting the station in install mode, what I was suprised by was the amount of dirt that had been drawn into to the fan guard and other parts of the Stevensons Sheild which all need a good wash with soapy water:

 

 

 

 

 

 

 

 

 

 

 

The original sensor is secured with two machine screws and the cable by a ‘P’ clip:

 

 

 

 

 

 

 

 

 

 

 

The replacement sensor was a direct fit as you wpould expects apart from the fact that instead of a ‘P’ clip, the environmental coating was used to form a cable clip, thit need a stand-off and additional machine screw to enable the sensor wire to be secured.

 

 

 

 

 

 

 

 

 

 

 

 

Once the housing was reassembled, sensor plugged up, fan reconnected and the station taken out of install mode everything worked just fine.

I’m awaiting the new fan to be deivered, so the second part of this will be blogged soon.

Cat5e Network Port Quick Finder

I was perusing the internet and came across a niffty idea to quickly identify which Cat5 outlet was connected to which port on a patch panel, so, as I had the parts, I thought I’d have a go.

The principle is very easy, in the patch panel,  RG45 plugs are inserted into each port, within the RG45 plug is an LED connected to pins 3 &6.

At the remote faceplate, a RG45 is plugged in which has power to pins 3 & 6 via a battery battery, the LED in the patch panel will now light, quickly identifing what is connected to what.

led plate
Test faceplate with pins 3 & 6 bridged across each outlet

 

 

 

 

 

 

 

 

 

 

 

The parts were from ebay:

  • LEDS – 100 for £2.32
  • RG45 connectors – 100 for £2.95
  • Battery Holder – £0.99

To make the LED plug, I first marked the Cathode of the LED so I got the polarity correct when inserted into the plug.

The next step was to flatten the LED capsule so that it fits within the cable entry of the connector.

The LED is now pushed into the connector and crimped, hot glue is then used to seal the LED in place.

The battery pack is powered by 2 x AA batteries, with a current limiting resistor terminated in the plug.

I made 24 of the LED plugs as that was the number of ports on my patch panel.

PLC Simulator

After playing with a Programmable Logic Controller (PLC) to operate my radio mast, I decided to build a simulator in order to better understand the capabilities of the EASY PR-18DC-DA-R.

I wanted the simulator to have 16 inputs, either momentary or switched and the ability to import signals including an embedded 4 – 20mA current.

I had a sloped project enclosure already, so I made a dimensioned drilling template.

Drilling Template

Once the template was stuck down, the pilot holes were drilled, template removed and holes opened to the right sizes.

Drilled Case

The template was created in Visio and I used layers, one of the layers was for switch position drilling and alignment cross-hairs, turning that layer off (missed one in I8!), allowed me to print on  self-adhesive sticky Matte White Vinyl.

Blank template

Using a sharp knife, I cut though the Vinyl and started fitting the switches, buttons, Output indication LEDs and 4 – 20mA injector.

Terminals to go in

Terminal posts next.

Switches going in

Front panel populated.

Wiring started.

Pre-wire

After a couple of changes, the internal wiring is completed and loomed in.

Wired

The simulator uses 24v DC, I used a small 1.5A output switched mode PSU for this, fed via a chassis fuse holder with the supply from an IEC male socket, the output from the PSU is fused separately.

PSU 24v

PLC simulator all powered up, the program in the PLC was legacy from my mast control project, this will be overwritten by downloading revised programs from xLogicsoft software.

To complement the PLC simulator I bought a4-20mA Current Signal Generator 0-10V Voltage Generator Transducer Simulator for £19.00.

Boltek LD-250 Relay Interface

The LD-250 Lighting Detector from Boltek has an internal output for a relay interface, the manufactures units are quite expensive, so I decided to make my own.

RLO-10 Boltek Relay Interface

Inside the LD-250 is a 14 way header which connects via ribbon cable to the RLO-10, off eBay I bought the 14 way ribbon cable and IDC cable mount socket for £5.00.

Opening the LD-250 the header JP1 is immediately obvious:

Using my multimeter, the header output pins linked to the front panel LED’s and the operating voltage was quickly found.

diagram

Using a spare strip of veroboard I mounted a magnetically shielded reed relay 5v, with flywheel diode across the coil, and the switched Normally Open reed output to a 2.54mm x 2 pitch connector, I also put veropins in the board so I can select which function I want the relay to operate on, should it be needed in the future.

The reed switch is used to switch 24v DC to an indicating LED and a a PLC input, the total load was measured at 21.49mA, well within the 500mA rating of the reed switch.

The module was placed in a small enclosure:enclosure

 

 

 

 

 

 

 

The ribbon cable was then plugged into JP1 inside the LD-250:

Switching on the Boltek performs a self test of the front LED’s and internal buzzer, as I have used the output from the ‘Close’ LED, the reed relay operated and the mast which was raised, automatically retracted.

All in all the project performs as expected and cost me £7 (enclosure was £2) saving me £58.95 on a factory unit.

Virgin Media FTTH – Chatteris

Virgin Media FTTH – Chatteris

Updated 11 Apr 18

This blog is about the roll out of Virgin Media fibre to the home in Chatteris from the civil works through to the delivery of a live service at my house and beyond.

Timeline of my installation:
  • June 17,  Virgin Media (VM) started FTTH works in Chatteris.
  • 23 October 17, VM started trenching in Farriers Gate outside Glebelands school.
  • 24 October 17Letter pushed through the door from VM
  • 25 October 17, Trenching and Toby installed.
  • 26 October 17, Trench tarmacked and construction barriers removed.
  • 5 November 17, I buried 20mm conduit from Toby to house wall and included a draw cord.
  • 26 Nov 18, Cabinet AF0503 made live.
  • 1 Feb 18, Virgin Postcode Checker now shows service available in my street.
  • 4 Feb 18, Ordered VIVID 200 package for installation on Friday 23 Feb 18 between 13:00 – 16:00. Went through to the Virgin Media shop in Peterborough looking for some form of promotion or deal to reduce costs, this didn’t happen, in fact they suggested I could save money ordering in shop as they would waive the installation and F-Secure costs, this was incorrect as the online booking information has these as free, also they wanted £25 up front, £20 activation fee and £5 which would be returned once the service was active, online it is £20 only activation, so I booked online, as an aside, if I had ordered in the shop my statutory rights to cancel is reduced from 14 to 10 days protection which you get when booking online.
  • 11 Feb 18, received two e-mails, the first containing e-sign contract, the other was what to expect on the day of installation.
  • 16 Feb 18, received mobile call from Callum of the Virgin Media installation team wanting to come and install a microduct from the Toby to my house, fit the Omnibox and blow the fibre from the street cabinet to the Omnibox, this is done a week in advance of the engineers on the 23 Feb, I arranged for the following day to meet them as I was 180 miles away! (this part of the process was not known to me and came out of the blue, I assumed it would be a ‘one hit’ visit).
  • 17 Feb 18, James from the installation team rang to cancel as Callums son had a fall and was needed at home, as the install is a two man job I returned his call and rearranged for Monday 19 Feb after 16:00.
  • 19 Feb 18, James & Callum turned up at the appointed time to install the microduct, fibre and Omnibox.

toby

The guys first photographed a laminated sheet showing my address, date and their names next to my open Toby, once this was done they threaded a black microduct pipe from the pavement Toby through the conduit I had previously laid to the house, the brown Omnibox was fixed to the wall with 4 screws and the microduct pipe clipped into place in the Omnibox,  at the Toby a coupling was installed transitioning from the green microduct to the black microduct.

coupling
Transition coupling, black microduct to house, green microduct to street cabinet.

The distance was measured using a measuring wheel from my Toby to the street cabinet (72.5 m), while the measuring was going on, compressed air was blown down the microduct from the house, this caused the yellow protective cap to be blown off the end of the green microduct in the cabinet, identifying which tube out of many,  as coming from my house.cabinet

In the cabinet a ‘fibre catcher’ was fitted, at the house end the fibre cassette containing 100m of fibre  was fixed on a device which enabled the fibre to be blown into the duct until it was caught by the cabinet catcher.blow

At the cabinet, the fibre catcher was removed and a protective sleeve was fitted over the fibre and terminated in a connection, this connection was then plugged into a breakout panel in the cabinet.

tap
We were the first in this cabinet.

At the house end, the surplus fibre from the cassette was wrapped within the Omnibox, the house end is pre terminated, once this was done, a reading was taken of light losses (-0.13db) to check they were in an acceptable range, the reading was photographed with the laminated sheet used earlier as proof of service in advance of the technical install scheduled on Friday 23 Feb 18.

omnibox
Completed Omnibox after first visit ready for the optical media converter and splitter to be fitted.
  • 23 Feb 18, Go Live Day – Engineer Sam arrived between the allotted time of 13:00 to 18:00 to start the installation.

install

He was quite happy that the hole through the wall into the lounge was already in, as was the dry lining that he could hang the Isolated Power Injector on.

First job was to push a peice of HFC cable though the wall from the Omnibox and put a connector on the end, this was connected to the Isolated Power Injector  (IPI) Teleste IP1-G1)), which is mounted within an enclosure on the lounge wall (the screw holes of the enclosure and backplate fit a standard dry lining box), a short length of HFC cable from this goes to a 12v plug in PSU in order to back feed the external optical media converter with power.

The bottom IPI output  is connected to a 2 way splitter (Technetix ESX-02), one leg goes to the router (a 3db attenuator was installed to balance the system), the other leg to the TV box.

As the TV box, Router and Optical media converter require power, three 240v sockets are required.

In the Omnibox, the HFC cable  was terminated, and plugged into a DC passing port of the 4 way splitter (Amphenol Model ABS104TP), from the splitter this is plugged into the Vector Boostral 610 optical media converters output.

Schematic

Once the external works was completed, the router and TV box were powered up and an Ethernet cable from the router to TV box was plugged in.  The hardware went through  three re-boots and software updates and I was good to go.

  • 24 Feb 18, Netflix is suffering lip sync issues when viewed through the VM TV Box, also download speeds vary from 210Mb to 38Mb (wireless tests), it’s early days, so I hopefully this will stabilize soon.
  • 25 Feb 18, Speed test using direct cabled connection to Virgin Media router (200Mb service ordered) :

speedtest

25 Feb 18 @ 14.11

  • 2 Mar 18,  TalkTalk, my existing provider reduced my package ‘Fibre Large’ which is  Fibre To The Cabinet’ (FTTC) by £26:25,  on knowing I was thinking about leaving for Virgin Media, they did this by moving me to the ‘Faster Fibre Plan’.

I get the same package as before (TV, broadband and phone landline including line rental) for £31.75 per month, the download and upload speeds I’m getting are more than enough for my needs even when all the kids are home battering the broadband, also I keep my landline, Virgin Media have not yet enabled VOIP on the router which was another factor for me.

I called Virgin Media to cancel my arrangement (within the 14 day ‘cooling off’ period), they obviously asked why and I mentioned the main reason was cost and as an aside, that my wireless speeds were faster with TalkTalk rather than Virgin Media.

Perplexed by this, he transferred me to technical in a foreign land and they remotely checked the line and rebooted the router, then asked me to perform a router reset using a paperclip, which I did whilst they were on the phone.  They assured me everything was working properly and I did a wireless speedtest and managed 136Mb download.

Checking later I took the following images of speed:

speedtest vm
Download 49.4Mb, Upload 12.5 Mb from Virgin Media
speedtest talktalk
Download 62.3Mb, Upload 17Mb from TalkTalk on 5GHz

The above results used OOKLA Speedtest on an iPhone  6, as the SSID on the Virgin Media router is the same for 2.4GHz and 5GHz I didn’t know which Wi-Fi band I was measuring, I was however, the only device was connected to it.

For balance I ran another TalkTalk test at 2.4GHz, and the readings came out at Download 41.7Mb, Upload 16.8Mb which wasn’t too shabby, especially as 7 wireless devices were connected.

I also ran a directly ethernet connected Virgin Media router test later with a laptop at 20:00hrs 2 March 18, and managed a download speed of 76.17Mb and upload of 10.3Mb, not brilliant for an upto 200Mb service which I was assured was working as it should.

The upshot is that I staying with TalkTalk meaning that I reluctantly terminated my arrangement with Virgin Media effective from 3 March 18.

  • 8 Mar 18, Disconnected my Virgin Media as per the instructions which came in my returns packaging and boxed up the  following way as requested:
  1.    Router;
  2.    TV box;
  3.    Remote control;
  4.   Two power supplies;
  5.   Leads for the above PSU’s;
  6.   Splitter and three CATV cables.

This was then taken to my local ‘Click & Collect’ store and it was winging it way back to Virgin Media at nill cost to me.

  • 14 Mar 18, Text from VM to say the kit has been received and any charge for kit that might have been applied to my account will be credited, also received an e-mail:

return note

  • 21 Mar 18, Received my first and last Virgin Media bill, this covers the week I had the service and the activation charge, total payable – £36.67.

virgin bill

  • 30 Mar 18, Checking my bank statements and no money has been taken by Virgin Media so I cancelled the Direct Debit to them.
  • 1 Apr 18, Received e-mail from Virgin Media thanking me for joining them and asking me to complete a short survey which I did even though I’m no longer a customer.
  • 4 Apr 18, Virgin Media activity showed on my bank statement ( – £36.76 then +£36.67), contacted VM and they said I do not have to pay anything as I cancelled within 14 days.
  • 11 Apr 18, Text from Virgin Media to call 0800 052 2630 in order to clear my outstanding balance, talked to Kirsten and she saw the error that cancelling within 14 days shouldn’t  have triggered a bill, so she added a small credit to my account in order to cancel the debt on the system.

Chatteris Fibre To The Home (FTTH) Story:

Headline  – The bulk of the infrastructure took 10 months to install (June 17 – March 18), comprising:

  • 36.3 miles  (58.4Km) of ducting
  • 2 Nodal Hubs
  • 11 Level 3 street cabinets
  • 123 Level 4 street cabinets

As part of Connecting Cambridgeshire Virgin Media are rolling out super fast broadband.compare

Hybrid Fibre-Coaxial cable and below that a fibre optic connector

Phased civils started in June 2017 and by 4 January 2018 first subscriber activated.

I currently use TalkTalk Fibre to the Cabinet, this the same as BT Infinity, SKY, Plusnet etc, this means a fibre optic cable is brought from the local exchange to a street cabinet, from this the existing telephone copper cable is used for  broadband and phone, depending how close you are to the cabinet will determine how fast your broadband is, in may case, I get a maximum speed of 62.79Mbps download, 17.34Mbps Upload and a Ping time of 17.34ms which is probably the best I can get (using Speedtest 15/11/17 @ 18:00).

Diagram showing how Fibre To The Home (FTTH) is just that.

I was delighted when I saw that the Virgin Media cable enabling works was scheduled for installation  via Roadworks.org, bringing up to 300Mb speeds to Chatteris, this will give people an option, rather than be tied to telephone line provided services, so I thought I’d start this blog.

This speed test was done on the 25 Feb 18 @ 14.14 by directly connecting a cable to the TalkTalk router to compare FTTC with Virgin Media FTTH:

Infrastructure Process

The infrastructure in my area was due to start on 4 August 17, expecting to last until the 14 August and I registered my interest in advance  using Cable My Street.

My roads infrastructure work started on the 23 October 18 and was carried out very swiftly and with minimal mess considering the civil work required, the works was undertaken during school holidays to minimise any disruption, the crew were respectful of any request to get on and off the drive, also in my case I wanted the  ‘Toby’ to be in a particular position, this wasn’t a problem and on the pictures below you can see the original point marking has been crossed out, and the new position marked as a red box.

Time lapse video of Virgin Media installing FTTH infrastructure.

Details on how the Virgin Media infrastructure is installed (for developers but a great resource) is HERE (large file) and a general guide used for another town scheme is HERE.

The system we are getting from Virgin uses RF over Glass, with the infrastructure being installed by John Henry Group. This comprises of a fibre optic cable laid in a trench which is blown through a microduct tube from the nearest cabinet to the home after your order is placed.

The marker tape which is put over the buried Virgin Media infrastructure and serves two purposes, the first is to allow detection using a Cable Avoidance Tool (CAT), the marker tape has two metal wires bonded to it, so the route of the tape can be found and traced from the surface without excavation, the second purpose is to warn that you are about to unearth or hit cables should you be digging.

Within the distribution board above is a smart RCD from Tii-Tech which is rather clever as it performs regular operational self tests to avoid the need for a person to visit the cabinet to do them. This write up from Gewiss explains how they work.

End of Line Termination Boxes

From the street termination box, a microduct coupling is used to extend the duct from the street cabinet to your outside wall, the fibre once blown through is connected to a media converter within the externally mounted Omnibox

Showing the three different coloursof Onmibox used in Chatteris, the last one is mine.

The  media converter changes the fibres optical pulses of light into electrical data which a coaxial cable then takes to the Super Hub 3 Router and connectivity to the internet.

Cassette of single mode fibre, pre-terminated, up to 500m in increments of 25m are used dedpending on the distance from home to cabinet (25m, 50m, 75m, 100m, 125m, 150,m 300m & 500m).

This configuration will give data transfer speeds of up to 300Mbps, a basic outline of how it connects together is below, the VM Datacentre is in Wisbech and Chatteris is fed by a direct fibre from their:

Background

The cabinet backs onto a Grade 2 listed house and a black one was requested as it matches the surrounds a lot better than a grey one.  A point to note is that the ground level in the house is lower than the pavement. The contractors started digging up in front of one of the windows put a grey cabinet and it was a foot above the bottom of the window and as the house is lower inside when you looked out the top of the cabinet was eye height. The owners asked if they could move it down the street more which they did but then backfield the hole they dug with hardcore they took out and left it. With have requested several times for last 2/3 months if it can be re-tarmac to stop water running into the house which is going to collect there.

12 Nov 17, ground under window not restored.

Voltage Control Relay

Link back to Radio Mast Automation – HERE where the EASY RL-V23 unit can just be seen attached to the lid of the mast controller.

Voltage Unit
EASY Voltage Unit

The above module was from eBay and advertised as a ’12V Voltage Control /Delay Switch /OverVoltage /Under Voltage Protection Module’ for £4.92.

This unit is incredibly versatile, and I’ve included the operating instructions in the blog.

I have used this module to monitor the charging voltage of a battery, once the voltage has reached a pre-set value, an output will trigger to stop the charger.

2 Operating modes:

Connect to power, LED digital tube displays words “E-A-Z-Y-t” in turn, system enter into the selection state, the initial mode selection is displayed as “P-0”, press the “SET” button to select “P-1~P-8” mode, press “ENTER” to enter the corresponding mode.while any mode running, press the “ENTER” button for 3 seconds, system will return to the mode selection state.

Press the “SET” and “ENTER” button to connect the power, the controller will be restored to factory settings.

2.1 Timer mode (P-1)

Press the “SET” button to select “P-1”, controller system will enter into the timer mode.

“P-1”/ “P-2”: 1-999 seconds /minute can be set.

Cyclic run:

In the timer mode, the user can set the relay’s close time T1 and the release time T2,such as setting T1 for 3 seconds, T2 for 7 seconds, the relay will be closed for three seconds then release for 7 seconds, cyclic run.

User also can set cyclic times.

When you have set the values of the T1 and T2 , the system saved the settings, the next time system will be loaded automatically T1 time to wait running.

Timer:

If you set T1 with a specified time, set T2 (release time) with 0, the relay will stop after the timer run T1 time, no longer running, it can be used as a timer, with running time end, the normally open contact of relay release, then press the “ENTER” button, the system re-start the timer for T1 time.

In timer state, you can use external switch or pulse signal input Interface on controller to start the timer (trigger).

Timer setting steps:
1) For the first time of set , select “P-1” time relay mode, LED digital tube display” 000 “;

2) Press the “SET” button, system will enter into the T1 time values settings first, the digital LED that wait for set flashing with 1Hz frequency, press “ENTER” to select the number of values, press the “SET” button for three times to enter the T2 time values settings, and cyclic times, press the “SET” button to exit the set state, the system waits to press “ENTER” button to start running.
3) In the time setting state ,time values’ unit can be switched to minutes unit or second unit, press the “SET” button to enter the time set by state (set LED digital tube flashing) ,at this time Press the “SET” button for 3 seconds to release ,the LED digital tube will light the right decimal points, it means that timing values with minutes unit, if the decimal point dose not light, it means that timing values with seconds unit.
4) After setting is completed, press the “SET” button to exit the setting state, press “ENTER” to start timing, if timing values is set with second unit, seconds values will display with countdown form. If timing values is set with minute unit, the right decimal point flashing with 1Hz frequency, means the countdown is running. While timer is running, the normally open contact of relay connected, the normally closed contact of relay disconnect, press the “ENTER” to halt run, press the “ENTER” for three seconds to return mode selection state “P-0”.
2.2 Delay timer (P-2)

The Setting method of “P- 2” is the same as “P- 1”, in the mode of “P-2”, the relay will first execute release of T1 time then closed with T2 time.

2.3 Voltage control relay mode (P-3)

In mode selection state(“P-0”), press the “SET” button to select “P-3”, then press the “ENTER” to enter the voltage comparison control mode, the controller will detect voltage from “VOL” Interface and display values (DC 0-99.9V),it also can be used as a DC voltmeter ,the default initial run state relay contact is closed (normally closed contact is disconnected, normally open switch on), press the “SET “button to set the three bit values, the LED digital tube is set to flashing with1Hz frequency, first to be set upper limit voltage values , press the “SET” button three times, lower limit values of voltage to be set,press the “ENTER” button to increase the number of values, the lower limit voltage can not exceeds the upper limit, press the “SET” button to make digital tube is no longer flashing, this time system enter into voltage control mode , the controller detects DC voltage from external input Interface , when voltage detection exceed the upper limit of the pre-set, the relay close (normally open contact connect ,normally closed disconnect), until the voltage drops below the lower limit pre-set, the relay will release (normally closed contact connect , normally open contact disconnect).

In voltage control condition, press the “SET” button for three seconds then release the button, the contact of relay state will be reversed. such as: the relay close when detect voltage below the lower limit voltage.

If the pre-set voltage upper and lower limits set to the same, such as 12.0V, when controller detect volts at 12.0 fluctuations may cause the relay contact frequent action, we recommend to set the voltage to maintain the difference between the upper and lower limits.

Note: The detection voltage terminal must connected reliable, have not loose wiring around the circuit board insulation ,may lead to the induced voltage detection values is not accurate.

2.4 Voltage control Timer mode (P-4 / P-5)

“P-4” or “P-5” mode is composed of “P-1” and “P-3” or “P-2” and “P-3”.When the system switched to “P-4” from “P-1”or“P-2”,it will enter the voltage control timer mode, the controller will detect voltage from “VOL” Interface ,when detect voltage exceed the upper limit of the pre-set voltage, the timer will start , until the volts drops below the lower limit pre-set , the timer stop.

If you set time in “P-1” mode previous, then enter the “P-4” mode , the relay will close with timer first ,then release, If you set time in “P-2” mode previous, then enter the “P-4” mode ,the relay release with timing then closed.

The difference between “P-4” and “P-5” is the relay’s Initial state, “P-4” mode relay release first, but “P-5” mode relay close first.

Press the button of “SET” last for 3 seconds, the timer will start in the case of the voltage is below the lower limit. the setting method of limit pre-set voltage, please refer to section 2.3.

For example:

(1) In P-2 mode , set T1 005, T2 000, then enter P-4 mode , voltage detection exceed the upper limit of the pre-set the relay will close after 5 seconds, voltage drops below the lower limit pre-set the relay release Immediately.
(2) In P-1 mode , set T1 005, T2 000, then enter P-5 mode, voltage below the lower limit pre-set the relay close immediately, voltage detection exceed the upper limit of the pre-set the relay will release after delay 5 seconds.
Voltage control logic can be reversed with press SET key for 3 seconds.

2.5 Voltage range control relay (P-6)

If the voltage controller detects exceed the upper limit of the pre-set voltage, or the voltage drops below the lower limit pre-set voltage, the relay will close, otherwise the relay release between upper limit and lower limit range. Press the button of “SET” last for 3 seconds, the relay reversed. The relay will close between upper limit and lower limit.

2.6 Voltage range control Timer (P-7)

If the voltage controller detects exceed the upper limit of the pre-set voltage, or the voltage drops below the lower limit pre-set voltage, the relay will run follow time relay mode that has been set in P-1 or P-1 mode previous.

When voltage values between the upper limit and lower limit range, press SET key for 3 seconds, relay reversed between close and release (ON/OFF).

For example:

In P-1 mode, set T1 005, T2 000, then enter P-7 mode, set relay close between upper limit and lower limit range. When voltage below lower limit or exceed upper limit, the relay will release after 5 seconds.

2.7 Set display shut (P-8)
The display shows “d-0” means keep bright, you can press the button of “SET” set 0-9 minutes for display shut.

Mast and Wire Rope protection & lubrication system

Mast and Wire Rope protection & lubrication system

I wanted a quick and easy way of applying protective lubricant to the wire rope which raises and lowers my mast, my first effort involved a paint brush and a tin of grease and I thought then that their must be a better method, both in terms of speed and effective application.

The option I chose was to use a spray wire rope and chain lube in conjuction with a home brew applicator.

applicator

The FORCE spray lube costs £6.25 for 400ml from eBay, the details of product are:

  • A long lasting highly tenacious spray grease which reduces wear and increases chain life.
  • High grip, anti fling properties provide long lasting, high depth lubrication and protection.
  • Penetrates inner rollers and resists the highest shock loads.
  • Ideal for chains, cables, wire ropes, fork lift chains, open gears and tail lift assemblies.
  • Reistant to weather and salt, provides high resistance to wash off.
  • ‘O’ Ring Safe unlike other greases!

Parts

  1. 1 off 10mm copper pipe 150mm in length
  2. 1 off 15mm copper pipe 135mm in length
  3. 1 off 4mm copper pipe 60mm in length
  4. 1 off 12mm panel grommet

Construction

The 10mm pipe had a 5mm slot cut down the complete length to allow the pipe to fit over the wire rope, at the base of the 10mm pipe I ‘flared’ this to 14mm.

The 15mm pipe was cut at one end with a roller type pipe cutter (pipe slice) and this formed a nice curved lip, at the other end I used a hacksaw, this pipe also had a 5mm slot cut down its length, for the cutting of the slots I used a dremel with a mini abrasive disc.

As the spray gease doesn’t come with extension tubes, I decided to use 4mm copper pipe (the 2mm inside pipe bore is perfect to slide over the spray cap nozzle), this was soldered half way up the 15mm pipe, this pipe enters directly opposite the cut slot. To act as a ‘key-way’ it protudes into the pipe by 1mm.

A 12mm panel grommet is cut to fit inside the 10mm pipe.

Operation

The 10mm pipe is slid over the cable with the flared section at the bottom:

10mm pipe

The grommet is installed at the top:

The 15mm pipe is now slid over the cable above the 10mm pipe and rotated so the grease inlet is inline with the slot in the 10mm pipe:

4mm inletNoting the alignment, the 10mm pipe is pushed inside the 15mm pipe, the 4mm pipe protuding inside the 15mm pipe ensures the 10mm pipe can only fully slide in if the slot aligns, The lip on the 15mm pipe holds the grommet in place:

grommetThe finished product works quite well and gives an even coating to the wire rope, the length of the 4mm pipe was to allow the spray can to rest on a bracket, so I simply raise the mast and hold the spray button down 🙂

Mast Lubrication

For the mast lubrication I use Lithium Grease, this is easy to apply from the spray can and is designed for metal to metal contact, a typical lubrication application for my mast with a rising section of 5.4m is 200ml.

Radio Mast Automation – Part 5: Control Modification

Since my last blog on Mast Automation when I thought I’d finished the project, I have made some changes to my weather station which means I no longer have an output to the mast controller, this output used to trigger the mast to lower when the wind speed hits 30 mph.

I decided to update the discontinued version of my Programmable Logic Controller (PLC) with a Rievtech PR-18DC-DA-R from Audon Ltd, this unit is a direct replacement for my old PLC and has 12 Inputs and 6 relay Outputs.

Rievtech PLC

The PLC accepts a number of input types, in my application I’m simply switching a voltage state with the exception of one of the inputs which is configured as an Analogue input, to which I have connected my mast mounted Anemometer as a means to trigger mast lowering during unsafe wind conditions.

  • Height (base to center): 105mm / 4.1″
  • Center out to Cup: 102mm / 4″
  • Arm Length: 70mm / 2.8″
  • Weight: 111.8g

Wire Dimensions:

  • Wire Length: 99cm / 39″
  • Plug Length: 30mm / 1.2″
  • Diameter (thickness): 4.8mm / 0.2″

Specifications

  • Output: 0.4V to 2V
  • Testing Range: 0.5m/s to 50m/s (111.8 mph)
  • Start wind speed: 0.2 m/s
  • Resolution: 0.1m/s

I tested the output  with help from my better half by driving at steady speed and monitoring the output from the anemometer:

  • 0 mph = 0.40  mV
  • 25 mph = 0.75 – 79 mV
  • 30 mph = 80 mV
  • 31 mph = 81 – 88 mV
Anemometer
Anemometer mounted on 2m/70cm H/V relay switch box

I mounted the anemometer to the top of my mast to get a representative wind speed, the next job was to strip out the old PLC from the control cabinet.

Mods
Starting mods, (hand held winch controller on top of cabinet)

I needed to make several changes from the original design in order to free up one of the PLC’s inputs, also out of the 16 Inputs only the first 6 allow analogue inputs, so some moving of inputs was needed along with some minor works to the LED voltages and override/luffing switch.

PLC
Completed Cabinet

All went back together quite nicely but an intermittent problem remained after the PLC replacement in that when the mast completed the mast raise cycle, the motor would immediately reverse and the mast would lower.

Hooking up the laptop to to the PLC, I selected ‘live monitoring’, this displayed the input and output condition, this showed that after operating the ‘raise’ toggle switch (centre bias On – Off – On centre off), the ‘lower’ switch input also went and remained high. This output to the PLC caused the motor to immediately  change direction and lower the moment the mast raised sensor was triggered.

To reduce the chance of a repeat problem occurring, I modified the replacement DPDT switch wiring so that both poles need to switch in order for a signal to pass.

switch wiring

Prior to starting the upgrade works I had the programmed PLC on the bench and I thoroughly tested all control permutations by simulation using the software from Audon Ltd to ensure correct operation.

  • Mast lowered output relay energizes. (Q004)

Wind Speed Triggered Auto Lower

Conditions –

  • E Stop not pressed. (Input 1004)
  • Top Securing mast pin IN. (Input 1008)
  • Mast in the raised position. (Input 100C)

Trigger –           Wind measured via Anemometer at 28 mph for 15 seconds. (Input A1001)

Action –

  • 0.4 – 2v Anemometer to Analogue Threshold Trigger output set go high at 80 mV and off at 76mV, these values equate to ~28 mph and ~24 mph respectively.
  •  ‘On Delay’ timer from analogue threshold trigger set for a sustained output of 15 seconds duration before the next stage is enabled in order to reject gusts.
  •  ‘Off Delay’ timer set to 10 minutes, if no input from the ‘On Delay’,  ‘Off Delay’ resets.
  • Whilst the ‘Off Delay’ timer is running, the WX Amber LED is lit. (Q005)
  • Output from ‘Off Delay’ to wiping relay timer set to 1 second to ensure a momentary output to the next stage.
  • 39 second down timer starts to operate Down relay (fail mechanism in case ‘lowered’ sensor fails).
  • Down relay closes to energize motor drive. (Q001)
  • After expiry of Down timer or on activation of the Down sensor, run on timer operates for 0.15 seconds to take slack off winch cable.
  •  After expiry of run-on timer, Down relay opens.
  • Mast lowered output relay energizes. (Q004)

Battery Charging Process

The winch has 3000lb capacity from Winch-It and is powered by a 12v car battery with a capacity of 45Ah – 360cca.

Normal Operation –    4.5w solar panel connected to the battery via CMP Solar Charge Controller.

Automatic Operation –

Trigger –       After 4 operations of the motors (raise & lower twice) or Weekly – Sunday 01.00

Action –

  • Multi-pole relay energizes after a 2 second delay via Q006, this:
  • Disconnects the solar panel.
  • Applies mains to a 4A output battery charger (charger sized for Ah of battery).
  • Connects the battery charger output to the battery.

Charging ceases when:

  • Battery terminal voltage reaches 14.14v (Over-voltage detection module to Input 100A).
  • 8-hour battery run timer expires.

Manual Operation –

Charging Start – Push button in control cabinet (Input 100B)

Charging Stop – Cursor key on PLC (C3)

Note –

If the battery charging cycle has started and the motor (either up or down) is operated, charging will cease and resume after a delay of 2 seconds after the motor has stopped.

Luffing the Mast

Conditions –

  • E Stop not pressed. (Input 1004)
  • Top Securing mast pin Out. (Input 1008)
  • Bottom Securing mast pin In (Input 1002)
  • Mast in the lowered position. (Input 1006)
  • Luffing switch set to On (Input 1007)

Trigger –           Momentary switch (raise or lower) (Inputs 1003 or 1005)

Action –            Operating the Luffing switch supplies power to the wireless receiver and manual switch which came with the Winch-It kit via a relay , the supply for this is taken from the Luffing/Override indicator LED, (the Luffing switch is a Double Pole Double Throw On – Off – On, the LED is fed from one side of the switch).

A further change to the control is to from latching to momentary switch operation allowing the motor to be ‘inched’ via the wireless handset or panel switches in the control cabinet.

Using the handset allows the mast to be walked down whilst lowering or the reverse when reinstating the mast to the vertical.

Override

Operating the Override switch bypass all limit switches and enables momentary manual control.

Amber LED indicating high wind has triggered lowering the mast and inhibiting it from raising whilst lit.
