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.

Actuator 5 on

Shaded DIP switches are standard factory settings.

If the Motor Load Transfer feature is enabled, it

will be activated following the Load Disconnect

Feature Delay Before Transfer delay.

Note

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:

*Enabling the Delay After Transfer will cause the
control signal to reset after the same delay as set for the
Delay 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.
