If the Meggitt Controller communication interface is inoperative, check the following: * Ensure the communication wires are correctly connected to both the actuator and the laptop PC. * Verify that there is 120 VDC Primary System Power at the Actuator. * Check the laptop/PC com port. * Remove any RESET or RUN commands.
Why Meggitt ACT1000 Controller actuator does not hold consistent position?
If the Meggitt Controller actuator does not hold a consistent position and oscillates or dithers, it could be due to: * A varying position demand signal. Ensure a stable position demand at the actuator. * No or low 120 VDC power. Make sure there is 120 VDC at the actuator.
Why Meggitt ACT1000 Controller actuator does not track position demand?
If the Meggitt Controller actuator does not track the position demand, ensure the following: * Position demand is greater than 4.1 mA at the actuator. * RUN command is present at the actuator.
How to troubleshoot no motor current feedback on Meggitt ACT1000?
If there is no motor current feedback from the Meggitt Controller actuator, check the following: * Verify the motor current signal is correctly connected. * Ensure there is 120 VDC at the actuator. * Confirm the RUN command is present at the actuator.
What causes no actuator feedback on Meggitt ACT1000 Controller?
If there is no actuator feedback from the Meggitt Controller, verify the feedback signal is correctly connected. Also, ensure 120 VDC is present at the actuator. If the actuator has auto shut down for self-protection, upload the fault file to check for shutdown faults. Finally, check for actuator contamination and ensure the RUN command is present at the actuator.
What to check if Meggitt Controller actuator inoperative with NO FAULT alarm?
If the Meggitt Controller actuator is inoperative and there is NO FAULT alarm, ensure 24 VDC RUN and position command at the actuator.
Why Meggitt ACT1000 Controller actuator moves toward HOME then stops?
If the Meggitt Controller actuator moves toward HOME then stops, ensure a consistent 24 VDC RUN command and position demand signal. Also ensure position command at actuator.
What to do if Meggitt ACT1000 actuator moves toward HOME intermittently?
If the Meggitt Controller actuator moves toward HOME intermittently, ensure a consistent 24 VDC RESET command.
How to clear Warning FAULT alarm on Meggitt ACT1000 Controller?
If there is a Warning FAULT alarm on the Meggitt Controller, upload the fault file to identify the source of the fault and clear the indicated fault.
What causes shutdown fault alarm on Meggitt Controller?
If the Meggitt Controller displays a shutdown FAULT alarm, allow the actuator to cool and restart it. Reduce the ambient temperature if the electronics or motor winding temperature is out of range. Check for actuator contamination.
