What to do if the red light is blinking on Motor Saver Accessories after the motor has been running?
If the red light is blinking on your Motor Saver Accessories after the motor has been running, it indicates that the incoming lines have been reverse-phased. To resolve this, you should correct the phase sequence.
Why is the green light on Motor Saver 201A-AU on steady, but the motor does not start?
If the green light is steadily on, but the motor isn't starting, the MotorSaver® is in run mode. Make sure other control devices are allowing the motor to start. Also, check the control circuit for any loose wires or switches that might be malfunctioning.
What to do if the red light is on steady on Motor Saver Accessories?
If the red light is steadily on, it indicates that the voltage is low. Measure the three line-to-line voltages and calculate the average. If the average voltage is 7% below the nominal voltage as selected by the LINE VOLTAGE ADJUST setting, the MotorSaver® is functioning properly. If the voltage is within 7%, call SymCom at (800) 843-8848 or (605) 348-5580.
How to fix a blinking red light on Motor Saver 201A-AU Accessories upon initial power-up?
If the red light is blinking when you initially power up your Motor Saver Accessories, turn off the 3-phase power. Then, swap any two leads powering the MotorSaver® (L1, L2, or L3). Reapply 3-phase power.
What to do if the red light is blinking on Motor Saver 201A-AU in this pattern?
If the red light is blinking in a specific pattern, it indicates that the voltage is high. Measure the three line-to-line voltages and calculate the average. If the average voltage is 7% above the nominal voltage as selected by the LINE VOLTAGE ADJUST setting, the MotorSaver® is functioning properly. If the voltage is within 7%, call SymCom at (800) 843-8848 or (605) 348-5580.
Why is the green light blinking and the motor is not running on Motor Saver Accessories?
If the green light is blinking but the motor isn't running, the MotorSaver® is either timing through the restart delay and will energize its contacts when finished, or the MotorSaver® is in manual reset mode and requires a manual reset to energize its contacts.
How to troubleshoot when no lights are on and the Motor Saver Accessories unit seems completely dead?
If no lights are on and the unit seems completely dead, verify L1, L2 & L3 are connected to terminals 3, 4 & 5. Measure the three line-to-line voltages. If any of the voltages are below the specified operating voltage, the MotorSaver® does not have enough power to operate its internal electronics. If the voltages are correct, call SymCom at (800) 843-8848 or (605) 348-5580.
