SAX31P03 / SAX81P03
3-position actuators must be controlled by a controller, see Connection diagrams [➙ 15].
SAX61P03
Up to 10 actuators can drive in parallel on a controller output with a rating of 1 mA.
Modulating actuators have an input impedance of 100 kΩ.
SAX61P03/MO
The Modbus converter is designed for analog control at 0...10 V.
Keep the analog signal setting on the actuator as is (switch 1 to OFF); adjustment no
t
permitted.
ASZ7.5
Actuators with a DC 0...9.8 V feedback signal are recommended for the combination
SIMATIC S5/S7 and position feedback.
Signal peaks in potentiometer ASZ7.5 may result in error messages on Siemens SIMATIC.
This is not the cause, however, when combined with Siemens HVAC controllers. The reason
is the higher resolution and faster reaction time on SIMATIC.
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.
