Operation Section 4: Operation Functional Tests and Adjustments CAUTION Following transfer switch installation and interconnection, inspect the entire installation carefully. A competent, Equipment damage. Do not use excessive force while qualified electrician should inspect it. The installation manually operating the transfer switch. Doing so could should comply strictly with all applicable codes, result in equipment damage.
Operation Close to Generator Source Side Generator Voltage Checks Before proceeding, verify the position of the switch by 1. On the generator panel, select the MANUAL mode observing the position of the manual operation handle in of operation. The generator should crank and start. Figure 4-1.
Operation 5. Set the generator main circuit breaker to ON or second warm-up delay. Let the system operate through CLOSED. The generator now powers all LOAD its entire automatic sequence of operation. circuits. Check generator operation under load as NOTE: Timer durations may differ between generators follows: and settings.
Operation Testing The SACM 2. Confirm generator MLCB (generator disconnect) is OFF (OPEN). A “Test” pushbutton is provided on top of the SACM to 3. At the controller, set the generator to AUTO mode. test the operation of the load shed functions. The test pushbutton will work when the ATS is in the utility or the 4.
