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.
FUNCTION S1 DIP SWITCH
enable Actuator 5 on
5
disable Actuator 5 off

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). T he 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:

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