Information
If a base unit and a contact expansion module from the PNOZsigma range
are connected via the connector, no additional wiring is necessary.
Operation
The unit is ready for operation when the Power LED is permanently lit.
LEDs indicate the status and errors during operation:
LED on
LED flashes
Information
Status indicators and error indicators may occur independently. In the case
of an error display, the "Fault" LED will light or flash (exception: "Supply
voltage too low"). An LED that is also flashing indicates the potential cause
of the error. An LED that is lit and is static indicates a normal operating sta-
tus. Several status indicators and error indicators may occur simultaneously.
