Operational Analysis
INITIAL DROPOUT OF UTILITY SOURCE VOLTAGE
Refer to Figure 96. Should a Utility power failure occur, circuit condition may be briefly described as follows:
•The controller continually monitors for acceptable Utility voltage via N1 and N2. Should Utility voltage drop below approximately
65% of the nominal source voltage, a programmable timer on the controller will turn on.
•In Figure 95, the 10-second timer is still timing and engine cranking has not yet begun.
•The AUTO-OFF-MANUAL switch is shown in the AUTO position. Battery voltage is available to the circuit board via Wire 13, the
7.5 amp fuse (F1). Wire 194 provides 12VDC to the transfer relay in the transfer switch.
