ULCD 2.0 ( GI-ELE-063 ) Wiring (Version 2)

ele-008.3.png

Find attached the wiring instructions for the GAS IT ULCD 2.0 unit. This GAS IT ECU ( Ultra Low Current Device 2.0 ) is designed to control the GAS IT Underslung LPG gas tanks fitted with the GAS IT electronic outlet device to turn the gas on and off remotely. ( GAS IT part Number GI-ELE-063) in a controlled manor.  This is not to be confused with our previous version of ULCD, PT number GI-ELE-008, which required a negative trigger on pin 3 ( the new 2.0 version requires a + trigger on Pin 3 now )

This is not just a relay.

It is a fully designed ECU that will operate the GAS IT tanks electronically outlet solenoid in the most efficient manor to allow the vehicles battery to last significantly longer than if the solenoid was just opened using a 12 volt switch or relay.  

Heres what it does : As the solenoid in our GAS IT tanks is opening and closing at full Gas tank pressure we need to fire the open operation of the gas tanks solenoid with full battery voltage and full opening current ( approx 1.2 amp ) to lift against the tanks gas pressure, but the ULCD is then designed to automatically lower the holding current of the solenoid in a controlled manor to approximately 0.07 of a amp there after.  This is important on a vehicle that is used for wild camping or off electric for any length of time for example ( to charge the battery ) as the ULCD's lower holding current means the vehicles battery ( a 110 amp leisure battery for example ) will last for approximately 33 days with the gas on full time before even half of the battery power ( amps ) are used.

If you are using this ULCD 2.0 with a rocker type 12v switch or any on /off switch connect the 12 volt + positive directly into pin 3

Please note whilst the ULCD is a waterproof unit, we highly recommend placing the ULCD unit in a dry location which can be either near or away from the tank. Also to aid wiring the green plug (with screw terminals ) can be removed and disconnected from the black electronic unit itself.
