What to do if my Bray Controller actuator does not operate?
If your Bray Controller actuator isn't working, here are a few things to check: * Ensure the override isn't engaged by pushing the handwheel in all the way. * Verify the wiring and power supply are correct. * If the actuator motor has overheated, allow it time to cool down.
Why doesn't my Bray Controller actuator fully close (or open) the valve?
If your Bray Controller actuator isn't fully closing or opening the valve, the issue might be due to several reasons: * Check if the limit switches are depressed and, if so, readjust the travel limit switches. * The mechanical travel stop might be stopping the actuator; in this case, adjust the mechanical travel stops. * It's possible the valve torque requirement is higher than the actuator output. Manually override the valve out of its seat and consider trying angle seating or using a larger actuator. * Also, verify that the voltage power supply is sufficient.
What to do if Bray Controller actuator operates in reverse directions?
If your Bray Controller actuator is operating in reverse, the field wiring may be reversed. Rewire the field wiring to correct this.
