    Cable for Proximity Readers

    I think it's to do with the large numbers of strands that make up the core. I read that the more strands/wires, the greater the range/distance so the tag can be energised further from the reader. I think :?:

    Cable for Proximity Readers

    Spoke to the agent of the kit today and they told me to try and source the cable myself and if I found a supplier, I had to let them know so they can get it. They can only sell the complete unit that contains the cable and not to bother asking for a price cause it was just stupid. I had a...

    Cable for Proximity Readers

    The coil is 230v. I'll see if I can get some more photos which include the details that are printed on the side.

    Timer Relay

    They are the same. The Schneider starters were supplied by the people that installed the auger and the spark called in to wire it supplied the timers.

    Timer Relay

    I take it theses Siemens relay timers are rated at 16A or above? Can't seem to find anything on the specs unless I am going blind.

    Timer Relay

    The other auger is identical. Both were installed at the same time. The overload 'hanging' is identical in the other auger. Both are schneider. The farmer has other equipment on the farm and they use Siemens kit and all have been excellent in reliability so might try that route. Fusing is...

    Timer Relay

    Neighbour has two separate augers in his milking parlour and each are controlled by a timer relay switch that are set for 10-15 minutes. One auger is always having problems with the time switch and it has been replaced twice already and has failed again. Seems to last 3 months at most. The...

    Metal Halide Startup Problem

    Its the non-photocell version. The light is on its own circuit and the meter was showing 236v. I guess it would be better to test the voltage in the light fitting itself. My local dealer stocks Ansell and every light I seem to get from that brand has problems switching on.

    Metal Halide Startup Problem

    The light is new. I haven't went back up to check the light but will take a look tomorrow. I can't tell you the tech bit of the light but this is the light after a quick search. http://www.superlecdirect.com/downloads/ProductDatasheet_A70MHL.pdf

    Metal Halide Startup Problem

    Spent yesterday installing a 70w Metal Halide outside which was an awkward installation. Anyhow, after all that work, the bloody thing switches on fine, but after 20 seconds or so, it goes out. If I go away can come back, it sometimes is back up running. If it does go out and I switch it...

    Lightning Strike Protection

    From from I read in the story, two sheds of cattle were affected and both contained scrappers, the scrappers that have a steel track down the passage which the scrapper travels along so it must have something to do with it when the other nearby sheds were ok. Basically, its a freak accident...

    Lightning Strike Protection

    I was at a house the other day and they showed me a newspaper which had a story about a Dairy farmer who went out to milk his cows one morning and found the cows in his shed all dead. It appears the previous nights lighning hit somewhere and the strike went down the automatic manure scrapper and...

    Wireless Thermostat for Oil Central Heating

    I've been looking at a few Honeywell thermostats from a DT92E which states for oil and then you have the fancy CMT921. What I notice with the CMT921 and sililar ones is that they have volt free connections, suitable for combi boilers. Can someone explain what it means by this and why its...

    Wireless Thermostat for Oil Central Heating

    I have a Riello Mectron 3bm burner/boiler outside and its controlled by an analogue time clock. I think its time I got a thermostat installed as its currently starting and stopping based on the water thermostat. I have been looking for a wireless thermostat but I don't know what works with an...

    Problem with HF Fluorescents

    Took two working tubes out of a light thats working and put them in the one's that aren't, and they don't even work. What a waste of money those lights were.

    Problem with HF Fluorescents

    Thanks for the replies. I am going to take a tube that's working and test it in those that don't work. Hopefully it's just the tubes and if it is, I wonder how long they will last. I'll know for next time to stick with Thorn.

    Problem with HF Fluorescents

    Just over a year ago I installed a number of High Frequency 58w Twin weatherproof fluorescents in one of my outbuildings. The lights have never been on this past few months due to the long evenings but this past few weeks, I have been switching them on. Every couple of days, there seems to be...

    Connecting 25mm SWA in CU

    My question was about connecting 25mm swa so the details I stated at the start was enough but I get your point if it was about something else.
