Frequently Asked Questions
Q
How do I perform a transfer test?
A
1. To perform a test, press and hold the transfer test button for at least 15 seconds or until the generator cranks. 2. Wait for approximately 10 seconds for the transfer to generator time delay. 3. Press the Bypass Time Delay button for immediate load transfer to the generator.
Q
Why doesn’t the engine exerciser light blink to indicate the remaining number of days until the next exercise period?
A
After the exercise period stops, the flashing light will remain on to indicate that the exercise is enabled and another exercise will be conducted after a week.
Q
How does the engine exerciser work?
A
The engine exerciser works by closing the engine start contacts and keeps it closed in order to crank and run the generator for approximately 20 minutes; after time expires, the controller signals the engine start contacts to open up and shut the generator down (after the 5 minute engine cool down period).
Q
Will the 185-switch work with a non-generator emergency source?
A
YES, it will work with a non-generator emergency source. As long as you have provided the necessary power cables to the transfer switch.
Q
Where is the ground bus located?
A
Upon opening the enclosure door of the transfer switch, the ground bus / lugs are located on the right side of the enclosure.
