If utility source voltage should drop below a preset value, the generator circuit board will sense the dropout. The 
circuit board will then initiate generator cranking and startup after a time delay circuit times out.
Figure 4 is a schematic representation of the transfer switch with generator power available, waiting to transfer.

•  Generator voltage available E1, E2.
•  Circuit board action holding Wire 23 open to ground.
•  Power available to standby coil C2, upon closure of TR1, normally open contacts (9 & 6) will close and initiate a

transfer.
