30 10. Trouble Shooting Floating Controller Motor does not operate and overheats Possibilities a. Supply power to #3 #4 simultaneously (Parallel Connection). b. The capacitor failed (whether the surface of the capacitor deforms). c. Valve s rubber is getting hardened or the valve s torque is excessive (it takes longer time to reach fully-closed position). d. Foreign objects in the flow stream. e. Broken motor stem or bearing. f. The limit switch for fully-closed does not trip. Solution a. Check the wiring for coupling wiring b. Replace to a new part. c. Use hand-wheel for test or change to a new valve. d. Check if any obstructions e. Replace to a new parts f. Operate the actuator manually to fully-closed position and confirm if the limit switch trips. The actuator is operated very well but the motor is hot. Possibilities a. Actuator operates too frequently (Starting frequency is too high). b. Overload. c. Under or over rated voltage. d. Mechanical stops are reached by the gear train at fully-open or fully-closed position. e. Wrong power supply. Solution a. Change system bandwidth or replace to a higher duty cycle actuator (refer to P3). b. This situation often happens after operating for a long time. It is suggested to replace to a new valve. c. Check the supply circuit. d. Reset the mechanical stops and cam (TC1 & TC2) (refer to P8~P11). e. Check the power supply. When operating two or more actuators simultaneously, the actuator works abnormally some times and the motor is getting hot. Possibilities Solution Parallel connection. a. Check current values and install a relay respectively.(refer to wiring diagram P48) The valve can not fully-open or fully-closed by either power supply or hand-wheel. Possibilities a. The actuator does not mount with the valve tightly during installation process. b. The torque of valve is larger than the torque of actuator. c. The set screw of the cam is loose. d. The installing angle of actuator and valve is not correct. Solution a. Contact technical department to solve the problem. b. Replace to a new valve or a larger actuator. c. Readjust the mechanical stops and limit switches (refer to P8~P11). d. Check the angle of the valve and actuator. 28

31 The capacitor is failed. Possibilities a. Overload (exceed the rated torque of actuator). b. Starting frequency is too high or ambient temperature is too high. c. Over service life. Solution a. Replace to a new part. It s suggested to change a new valve or a larger actuator. b. Replace to a new part and change to 75% duty cycle actuator (refer to P3). c. Check the capacitance and surface every year. Modulating Controller The LED (LD5~LD9) is flashing after the operating check is completed. Solution Refer to P30. The lamps on the modulating board are normal but the actuator can t work properly during test or it only can turn to fully open/closed position. Possibilities The signal is connected oppositely (means to signal failure). Solution Confirm if the input signal and the wiring are correct (terminal #6 connects to and terminal #7 connects to + ). Can not operate by modulating controller. Possibilities a. Faulty VR. b. The sector gear of the VR is loose. c. Wrong input signal. d. Faulty modulating board. Solution a. Replace to a new VR. b. Remove the input signal wires. Operate the actuator to fully-closed. Then readjust the VR (refer to P8~P10). c. Check if the input signal is correct (refer to P8~P10). d. Send back to factory for inspection. 29
