Wiring and Controller Setup
General
The SC refrigerant leak sensor is a series of transmitters for measuring concentration of
different gases. The transmitter is available in the Standard Room Type. The sensor
heads are semi-conductive, which provides a long lifetime and stability, but with limited
selectivity.
The transmitter gives a non-linear output signal (4 to 20mA or 0 to 10V DC) proportional
to the gas concentration. For long wiring installations, it is recommended to use the
current output signal to minimize the risk of interference. Output signal mode is set by
jumper (JP1).
