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.

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

REMOTE CONTROL FEATURES
These remote control features require a customer–supplied normally closed contact suitable for a 5 V dc low energy
circuit. Refer to the Wiring Diagram provided with the ATS. Activate appropriate DIP switch S2 actuators below.
