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 starti ng 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

Shaded DIP switches are standard factory settings.
If the Motor Load Transfer feature i s enabled,
it will be activated following
the L oad

delay.
Note
LOAD DISCONNECT FEATURE
Connect externalcircuits tothe terminalsindicated onthe
Wiring Diagram provided with the ATS.
The double throw(Form C)contact israted for28 VDC or
120 VAC (5 amps resistive). The contact operates priorto
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 (actuat ors 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 appropria te DIP switch S2 actuators below.
