The Big Idea
Not every facility has consistent incoming voltage. The MotorSaver® helps protect both motors and inverter from excessive voltage in areas where voltage spikes can occur. When the normal line voltage is present, the Green LED will illuminate and the relay will pull in. If the line voltage deviates more than 10% in either direction the internal relay will drop out stopping the machine. 2 seconds after the power is restored to the correct tolerance, the relay will reset and the contact will close again. If L1, L2 and L3 are not in sequence, the motor saver will not give a green light and not allow the inverter contactor to pull in, swap L1 and L2 if this occurs.
How to Install
- Set the incoming voltage range appropriately, 190 volts to 480 volts
- Wiring the Normally Open contact:
- On machines without a 3 wire circuit, like in J controls, wire the Normally Open contact in series with the inverter contactor coil "top side" feed.
- If you have a 3 wire circuit, connect the Normally open contact on the MotorSaver in series with the 3-Wire relay coil (top side) .
- There are two sets of contacts, either contact can be used.
- Set the relay reset time to 2 seconds.
- Use added jumper wires to connect the 3 phase power to the MotorSaver® L1, L2, and L3 input
Note During Installation:
When installing a new machine with a Motor Saver, if you see that you have a consistent flashing red LED for the Run Light, swap any 2 legs of the incoming 3 phase on the Motor Saver. This error means reverse phasing.
