Open-Circuit Test (contd.)

3.

Turn on input power to the regulator.

 

 

4.

Turn the rotary switch to the lowest brightness position (B1 for 5-

 

 

Step, B10 for 3-Step). The open-circuit protective device should

 

 

automatically de-energize the regulator in less than 2 seconds.

 

5.

Turn the rotary switch to OFF. The open-circuit protective device

 

 

should reset.

 

 

6.

Turn the rotary switch to position 1. The regulator should turn

 

 

on and then de-energize in less than 2 seconds.

 

 

7.

If regulator operation is satisfactory, turn rotary switch to OFF,

 

 

and turn off disconnect switch or main circuit breaker before

 

 

reconnecting the load.

 

 

8.

After the load has been reconnected, turn on input power to the

 

 

regulator.
