SIEMENS asz7.5 /1000 Potentiometer 0-1000 Ohm SA31/SA81
Notes on mounting
The actuator is mechanically connected to a Siemens valve. Observe compatibility and choice of combinations. Disconnect the actuator from power.
Attention
If AC 230 V connected danger to life!
Only required with actuators without fail-safe function.
Fit the screw covers first– otherwise the danger of life!
When mounting two different accessories watch out for correct plug-in space A or B Observe compatibility and choice of combinations.
Adjustment of zero point
Potentiometer ASZ7.5 (1000 Ohm) delivers an ohmic value to the controller giving the true position of the actuator (continuous position feedback). An ohmic value between P2-P1 increases with stroke H or rotation, an ohmic value between P2-P3 decreases. 5a
