Mount between valve and

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.
