9 TROUBLE SHOOTING
The following instructions are listed in the order of the most common difficulties encountered
during the installation and start-up.
► The actuator does not respond
• Visually inspect the actuator and check if no damage has occurred during shipping and handling of
the actuator.
• Verify the line voltage supplied to the actuator; it must match with the rating on the actuator’s
nameplate
• Compare and check the internal wiring with the supplied wiring diagram of the actuator
• Check the limit switch cams
► The actuator is supplied with power but does not operate
• Verify the line voltage supplied to the actuator; it must match with the rating on the actuator’s
nameplate.
• Make sure that the actuator output torque is greater than the required valve torque
• Check the limit switch cams
• Check if the torque switches have not been tripped
• Check the mechanical travel stop adjustment
• Check if the rotating direction matches (According to the applicable standards, valves and actuators
must open in counter-clockwise direction)
• Check the internal wiring
• Check for any corrosion and condensation. Electrical or mechanical devices may have been
affected
• Verify if coupler/bracket is correctly installed and may not block the actuator rotation
► Actuator runs erratically
• Check the ambient temperature
• Verify that the duty cycle has not been exceeded
• Check the position of the manual override lever
► Optional Equipment(s)
1) Potentiometer
• Check the resistance value
• Check the potentiometer gear for jamming
• Check the ZERO and SPAN calibration and confirm input/output signal
• Check the board for any damage
2) Current Position Transmitter
• Verify the input signal
• Check the configuration of the dip switches
• Check the board for any damage
