11.5.1 UMA Voltage output pressure sender
Pinout:
White/Orange: +12Vdc
White: Signal
White/Blue: Ground
Shield: Ground
11.5.2 ROTAX 912/914 4-20mA Pressure sender
The sensor cable is approximately 3m long and has 3 leads. The black lead is not to be connected and has no function.
The Red lead from the sensor has to be connected to the positive bus via a fuse or circuit breaker . The white lead
(Output signal) has to be connected directly to the EMS-1 analog input channel. The supplied 100Ohm 1/4W resistor
must be connected across the analog input channel to ground. The internal pull up resistor dip switch for the 4-20mA
current sender input must be in the “OFF” position.
