OPERATIONAL ANALYSIS
PART 4
Figure 5. Circuit Condition - Initial Transfer to Standby
• Standby power is now delivered to the standby closing coil (C2), via Wires E1 /E2, the normally open transfer
relay contacts, Wire 205, limit switch XB1, Wire B, and a bridge rectifier. The standby closing coil energizes and
the main current carrying contacts of the transfer switch are actuated to their STANDBY source side.
• As the main contacts move to their STANDBY source side, a mechanical interlock actuates limit switch XB1 to
its open position and limit switch XA1 to its “Utility” side position. When XB1 opens, standby closing coil C2 3
de-energizes.
• Standby power is delivered to the LOAD terminals (T1/T2) of the transfer switch.
• As load is applied to the generator, the current transformer (ICT) induces AC voltage that is applied to the circuit
board via Wires LC1 & LC2. This voltage is utilized for stepper motor control.
