7 Operation
When the supply voltage is switched on, the PNOZmulti safety system copies the configur-
ation from the chip card.
The LEDs “POWER”, “DIAG”, “FAULT”, “IFAULT” and “OFAULT” will light up on the base
unit.
The PNOZmulti safety system is ready for operation when the "POWER" and "RUN" LEDs
on the base unit and the "READY" LED on the PNOZ ms2p HTL are lit continuously.
