The user is responsible for ensuring that a switching load of 8A /
150 VA (W) is not exceeded in the event of a fault. Internal spark
suppression by means of two zinc oxide varistors (275 V). The output
relays of the instrument (1 relay or several) may only be disengaged
in total
5 x per minute at the most. Admissible clicks
according
to interference suppression standard EN 61000-6-4 for the industrial
sector. In case of a higher switching rate, the operator must take
care of interference suppression on the spot and under his own
responsibility by observing the load to be switched.

Assign terminals 20, 21, 22 and 23, 24, 25 accordingly.
3.4 Assigning the signal inputs
Terminals 6 to 9 are signal inputs. Terminals 6 (track A) and 7 (track B)
are signal inputs for the counter. The type of signal and signal logic
are programmed in lines 25 and 28. Terminal 8 serves as the reset
input. The counter is reset by way of an external signal (signal width
> 30 ms). Terminal 9 (stop) is programmed for stop/hold/operating
hours (line 31).

3.5 Connecting the sensor supply
Connect the sensor supply at terminals 4 and 5.
Do not use the sensor supply to supply non-earthed inductive or
capacitive loads.
The sensor supply is not short-circuit proof.
