16 DIAGRAMS FOR TESTING WITHOUT A GENERATOR

Below is the connection diagram for shop testing, where the equipment can be verified for proper operation.
Material needed:
1 – Small screwdriver;
1 – Incandescent Lamp;
1 – Lamp socket;
1 – Two pole circuit breaker (recommended 5A);
1 – Extension cable or Power strip;
1 – 110V or 220V power outlet *.
* For 220V voltage select sensing jumper to class "A";
* For 110V voltage select sensing jumper to class "G";
1º - Put together a circuit as shown on the the diagram beside;
2º - With a small screwdriver, turn the Vad and U/F trimpots counterclockwise until the end of its course;
3º - Turn ON the circuit breaker:
4º - Turn the Vad trimpot slightly clockwise
(the lamp should gradually increase its brightness as the trimpot is turned);
5º - With the Vad trimpot adjust for maximum voltage and the lamp on, turn the U/F trimpot clockwise, (the lamp should
gradually diminish its brightness until turning off as the trimpot is turned);
6º - Slightly turn the U/F trimpot counterclockwise (the lamp should gradually increase its brightness as the trimpot is turned);
7º - With the lamp on, slightly turn the Vad trimpot counterclockwise (the lamp should gradually diminish its brightness until
turning off as the trimpot is turned);
8º - Turn OFF circuit breaker.
After all the steps above have been completed the equipment should be operating properly.
NOTE
1. If any step deviated from the described procedure, the equipment should be sent back to be
evaluated by the WEG technical support department.
