What to do if Rotork Controller is unable to fully open or close?
If the Rotork Controller is unable to fully open or close, adjust the cams if they are not set correctly, investigate the valve if there is a bent valve stem, and reset the stop bolts if the stop bolt adjustment is incorrect.
Why does my rotork ROM 1/A motor overheat?
If the Rotork Controller motor overheats, verify the voltage is correct, investigate the valve for tightness, and check the duty-cycle due to a potentially high working frequency. If the voltage is not correct, check it. If the valve is too tight, investigate it. If there is a high working frequency, check the duty-cycle.
Why is my rotork ROM 1/A actuator running in the wrong direction?
If the Rotork Controller actuator runs in the wrong direction, check the remote control circuit for incorrectly connected terminals and change the phase wiring if the 3-phase wiring is incorrect. If wrong terminals are connected, check the remote control circuit. If there is wrong 3-phase wiring, change phase wiring.
What to do if rotork ROM 1/A Controller operates but there is no valve moment?
If the Rotork Controller operates but there is no valve movement, replace the adaptor if the drive adaptor is worn and investigate the valve if there is a broken valve stem.
Why is there erratic operation of multiple Rotork Controllers?
If you experience erratic operation of multiple Rotork Controllers, it might be because multiple actuators are on the same control circuit. Actuators must have individual control circuit.
