actuator
Note: ASZ7.3 For the combination SIMATIC S5/S7 and use of positioning
feedback, we recommend actuators with DC 0...9.8 V
feedback signals.
The signal peaks that occur in the potentiometer ASZ7.3
may result in error messages on Siemens SIMATIC. This is
not the case when combined with Siemens HVAC
controllers. The reason is that SIMATIC has a higher
resolution and faster response time.
Use the potentiometer as voltage divider on the 3-wire
connection. Powering the potentiometer over the wiper may
shorten the life cycle of the potentiometer. Signal peaks
increase in frequency and scope over the lifespan in this
operating mode.
