A/C Signal
A/C Pressure TransducerThe signal from the pressure transducer is a varying voltage type. Higher voltages indicate higher pressure, lower voltages lower pressure. Normal operating range is approximately 1.2 - 2.0 volts.
An open in the transducer circuit will cause the EMS2000 to see maximum system pressure ( = / > 30 BAR) and disable the compressor from further operation.
