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.
