Fault indication for input circuit 1 / input circuit 2;
lights in case of wire break or short circuit in the respective input
circuit. The corresponding output is not active (transistor blocked,
relay de-energised).
3: LED green
Lights when supply voltage is applied.
4: Selector switch S1 Programming the output function
S1 / S2 = 1: direct operation (output switches like input signal: IN =
ON
➔
OUT = ON).
S1 / S2 = 2: inverted operation (output switches opposed to the in-
put signal: (IN = ON
➔
OUT = OFF).
For single-channel units S2 has no function.
