Operational Analysis
UTILITY SOURCE VOLTAGE AVAILABLE
Figure 66 is a schematic representation of the transfer switch with Utility source power available. The circuit condition is briefly
described as follows:
•Utility source voltage is available to terminal lugs N1 and N2 of the CONTACTOR; the transfer switch is in the “Utility” position and
Utility voltage is available to T1 and T2, customer load.
•Utility source voltage is available to the limit switch (SW2) via the normally closed transfer relay contacts (1 and 7) and Wire 126;
however, SW2 is open and the circuit to the utility closing coil is open.
•Utility voltage “sensing” signals are delivered to controller on the Generator, via Wire N1A, and a 5-amp fuse (F1). The second
line of the Utility voltage “sensing” circuit is via Wire N2A, and a 5 amp fuse (F2)
