B: Analog input voltage + 9 Vdc.

13 DIAGRAM FOR TEST WITHOUT ALTERNATOR

Below is the diagram for regulator connection on the bench where the equipment operation may be verified before
connection to the alternator.
Material required:
1 - Small screwdriver;
1 - Incandescent lamp;
1 - Lamp socket;
1 - Bipolar breaker (5A recommended);
1 - Extension cable;
1 - Plug 110V or 220V*.
* For voltage 110V, select refeeding jumper class "A";
* For voltage 220V, select refeeding jumper class "C";
NOTE
1. After performance of such steps as per the procedure the equipment must be sent for evaluation by WEG
technical support.
1º. Mount circuit as per diagram below;
2º. With small screwdriver, turn trimpots Vad and U/F counter-clockwise until the end of stroke;
3º. Turn on circuit breaker:
4º. Turn slightly the trimpot Vad clockwise (the lamp must shine after certain position of trimpot)
5º. With lamp on, turn slightly the trimpot Vad counter-clockwise (after certain position of trimpot, the lamp must turn off);
6º. Turn off the circuit breaker.
