Request to the external control system
Since the e-stop uses an internal voltage of 40 to 60 V
DC
within the unit, external relay switching by
means of a floating contact must be used for correct functioning. This switching can be adapted to
match the requirements of the external control system. The circuit situations are shown in the figure
below.

NOTE:
If you are not using the e-stop function, the bridged plug must be fitted to the e-stop connection
