Issue:
Is it required to have a dedicated power supply for the M800A actuator?

Product Line:
Valves and Actuators

Environment:
Installation

Cause:
Operation

Resolution:
The M800A actuator requires an isolated 50VA transformer, not powering anything but the actuator. Also, once the selection dip switches has been made for the control signal, you MUST power the actuator and move the dip switch #9 , OFF-ON-OFF, just that fast and let the actuator run through calibration.
