General Information
______________________________________________________________________________________________
Notice
Automatic mode without the cover may only be used by the technician during commissioning.
Barrels are under high tension and can cause injuries when disassembling. To disassemble, special tools are required
And therefore this is inadmissible.
Knob not inserted = emergency function triggered
Knob inserted = automatic mode
When the hood is removed, the emergency actuator automatically tests the emergency function and
moves into its safety position for safety reasons. To allow the commissioning technician to test
functionality, the emergency actuator can be switched to automatic mode by inserting the knob (1).
Remove the drive hood and then insert the knob (1) into the circuit board (2).
