CONTROL FEATURES (continued)

INPHASE MONITOR

FOR MOTOR LOAD TRANSFER

Inphase monitoring logic controls transfer and retransfer of motor loads, so that inrush currents do not exceed normal starting currents. It avoids nuisance tripping of circuit breakers and mechanical damage to motor couplings.

The Motor Load Transfer feature is built into the controller. DIP switch S1 (actuator 5) activates this feature: right = ON, left = OFF.

Shaded DIP switches are standard factory settings.

Note

If the Motor Load Transfer feature is enabled, it will be activated following the Load Disconnect Feature Delay Before Transfer delay.

LOAD DISCONNECT FEATURE

Connect external circuits to the terminals indicated on the Wiring Diagram provided with the ATS.

The double throw (Form C) contact is rated for

28 VDC or 120 VAC (5 amperes resistive). The contact operates prior to a selectable 0, 3, 10, or 20 second delay before transfer of the Automatic Transfer Switch. The contact resets either immediately following transfer or after the same delay as set for pre–signal before transfer.

Time delay between the load disconnect control signal and initiation of transfer is set on the controller with DIP switch S2 (actuators 6, 7, 8) as shown below:
