Operation
The TVM’s output contacts
energize when:
1. All phases are present;
2. The voltages are within the
adjustable range;
3. The phases are in proper rotation.
If any of these conditions are not satisfied, or if the voltage shifts beyond the over/undervoltage percentage around the nominal, the output relay will drop out after the drop out time delay. The LED lights when conditions are normal and the output relay is energized.
