Motorized Linear Actuator

6.2 Adjusting the potentiometer assembly
1. The potentiometer can be set to the defined zero point using the screw slot on the rear
(for normal mode clockwise up to the mechanical stop). For valve stroke < 44 mm,
note that for reverse mode, the potentiometer must be turned to the new zero point
(mechanical stop opposite). For this adjustment the actuator spindle must be in the
correct end position:
Normal mode: zero point = spindle extended --> potentiometer fully clockwise
Reverse mode: zero point = spindle retracted --> potentiometer fully anticlockwise
2. The additional limit switches can be adjusted by loosening and retightening the knurled
nut and setting the contact washers to the desired positon.
