To Next PageTo Next PageWhy is my Johnson Controls GH-5000 motor not running?
The motor might not be running due to several reasons: * Incorrect or missing supply voltage. Check the switches, fuses, circuit breakers, and actuator wiring connections. * The flow rate is set too low. Turn the ‘M’ adjustment screw counterclockwise to increase the flow rate. * There's an internal defect. In this case, replace the actuator.
What to do if Johnson Controls GH-5000 motor runs but valve doesn't open?
If the motor runs, but the valve doesn't open, consider these potential causes: * The operating pressure might be too high. Verify that the maximum operating pressure isn't exceeded. * The horizontal actuator might be incorrectly mounted. Turn the actuator and observe the correct mounting positions as indicated on the actuator label. * The stroke setting could be set below 3 mm. Turn the ‘R’ or ‘S’ adjustment screw counterclockwise to increase the stroke. * Check the flow direction, indicated by an arrow on the valve body. * There may be an internal defect, requiring you to replace the actuator.
What to do if Johnson Controls Control Unit actuator moves through low position?
If the actuator moves through the low position, it could be due to: * Incorrect wiring. Check the wiring. * A switch defect. Replace the terminal box.
What to do if Johnson Controls GH-5000 motor does not turn off?
If the motor does not turn off, the limit switch might be defective. Replace the terminal box.
Why is my Johnson Controls GH-5000 hot?
If the actuator surface becomes hot, it could be due to wrong operating voltage. Replace the actuator and check the operating voltage.
Why is there leakage from my Johnson Controls Control Unit?
Leakage can occur due to issues with the flanges or fittings. Replace the seals or screws, or if necessary, replace the valve.
What causes inner leakage in Johnson Controls Control Unit?
Inner leakage can be caused by: * Dirt on the valve seat. In this case, replace the valve. * Incorrect flow direction. Check the flow direction, which is indicated by an arrow on the valve body.
