Function Description
The bus interface PNOZ pe2p, in conjunction with the expansion modules, is used to ex-
pand a safety circuit. It is driven from a master controller (e.g. safe outputs on a PSS).
The unit is ready for operation when when supply voltage is applied and the feedback loop
Y1-Y2 is closed
}
24 V DC are available at the terminal K1 (e.g. the PSS output has a high signal):
– At the expansion module control output connected to the PNOZpower bus there is a
high signal.
}
0 V DC are available at the terminal K1 (e.g. the PSS output has a low signal):
– At the expansion module control output connected to the PNOZpower bus there is a
low signal.
NOTICE
When controlling an expansion module via the den PNOZpower bus the
switch-on delay/delay-on de-energisation of the controlling device and the
expansion module are added together.
Operating modes
}
Single-channel operation: no redundancy in the input circuit, earth faults in the start cir-
cuit are detected depending on the master controller.
