Faults – Interference
INFORMATION
Supply interruptions lasting longer than 20 ms are detected as an error. The
LEDs indicate an error and the safety outputs carry a low signal. The plant
or machinery driven via the safety outputs will be shut down. The unit can
only be restarted when the supply voltage is switched off for at least 1 s and
then switched on again.
Fault
Fault conditions are indicated by flashing the LEDs. There are faults that are displayed via
periodic flashing (see table "Display of fault conditions") and faults where an error code can
be determined via the number of flashes (see table "
Relationship between the number of
flashes and the decimal error code [
"). These faults are always indicated by three
short flashes at LED CH.1 or CH.2. After a longer pause, the LED will then flash at one
second intervals. The number of LED flashes corresponds to a digit in the error code. The
error code can consist of up to 4 digits. The digits are separated by a longer period without
flashing. The entire sequence is constantly repeated.
INFORMATION
Error code 0: 16 flashes
