switch-off after
Error cause
1 flash pulse Error (warning) at output Y1 30 min Fault in output test or voltage at output Y1,
although the output is disabled.
2 flash pulses Error (warning) at output Y2 30 min Fault in output test or voltage at output Y2,
although the output is disabled.
3 flash pulses Error (warning) cross-wire short 30 min Cross-wire short between the output cables or fault at both outputs
4 flash pulses Error (warning) temperature too
high
30 min The temperature measurement reveals an internal temperature
that is too high
5 flash pulses Actuator fault 0 min incorrect or defective actuator
6 flash pulses Error actuator combination 0 min An invalid combination of actuators was detected
(blocking bolt detection or tamper attempt).
Continuous red Internal fault /
overvoltage or undervoltage fault
