Comissioning and Configuration
The nominal current can be set for each channel individually between 1 A and 4 A.
Fig. 41: Setting the nominal current
All set characteristics are referenced to the set nominal current. The following table shows the response time
of the monitoring in relation to the nominal current and characteristic.
Nominal current Very fast acting Fast acting Slow acting Time delay
100 % 1 h - - -
110 % 1 h 4 h - -
120 % 7 min 4 h - -
150 % 30 s 30 min 1 h 4 h
210 % 500 ms 20 s 20 s 100 s
275 % 500 ms 1 s 20 s 10 s
300 % 20 ms 100 ms 1 s 3 s
If overcurrent (≥ nominal current) is detected and it is foreseeable that the current monitoring will trip if
conditions remain unchanged, then a warning is given both in the process data and in form of a flashing
LED. An output switch-off due to overcurrent is indicated by a red LED.
If one of the outputs was switched off due to a diagnosis, it must be reactivated by an active RESET.
Note
Restart after power OFF/ON
If an output was switched off due to an error, then an active reset by the RESET contact or
the fieldbus is necessary. Switching off and on again is not sufficient! To protect the elec-
tronic a RESET can be done at maximum all 20 seconds.
Switching on can be done either via EtherCAT or by applying 24 V to the RESET contact. To protect the
circuitry, a RESET can take place maximally every 20 seconds. Faster successive edges are ignored.
Switch-on delay of load circuits 1 to 4 without fieldbus control
Here is a table of the startup times, adjustable in the CoE object 0xF80E:11

Moderate 100 ms
Slow 200 ms
