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 expansion module PNOZ mmc6p is configured and started automatically. The LEDs
“RUN” and “ERR” display the status of the PNOZ mmc6p on CANopen.
If the expansion module PNOZ mmc6p does not receive a configuration from the base unit
for a period of 30 s, the expansion module PNOZ mmc6p connects to CANopen and "RUN"
status is displayed on CANopen. The error message "External Error" is sent to the Master.
