  • Ensure all motor connections are secure and properly seated on the timer poles.
  • Confirm the voltage of the timer unit matches the 480V requirement of the motor.
  • Check the timer's internal gears for any obstructions or damage.
• Incorrect Timekeeping:
  • Ensure the motor is securely mounted and not slipping.
  • Refer to your specific timer's manual for calibration or time-setting procedures.
• Unusual Noises:
  • Disconnect power and inspect the motor and timer gears for any foreign objects or damage.
