➥ If the PTC tripping device is working properly, the tripping of the motor protection
is signalled via the red indication light "collective fault signal" on the local con-

➥ The fault signal is reset if the device is working properly.
3. If no fault signal is initiated: Request AUMA service to check both wiring and

9.8. Potentiometer setting
— Option —
The potentiometer as travel sensor records the valve position.
Information This setting is only required if the potentiometer is directly wired to the customer
connection XK (refer to wiring diagram).
Information Due to the ratio of the reduction gearing the complete resistance range/stroke is not
always passed. Therefore, external adjustment (setting potentiometer) must be
provided.
