INPHASE MONITOR
FOR MOTOR LOAD TRANSFER
Inphase monitori ng logic controls transfer and retransfer
of motor loads, so tha t 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 ATSE.
The double throw (Form C) contact is rated for 28 VDC
or 120VAC (5 amps resistive). Thecontact operatesprior
to a selectable 0, 3, 10, or 20 second delay before transfer
of the automatic transfer switching device. 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 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.
