CONTROL FEATURES (continued)

5--4

INPHASE MONITOR

FOR MOTOR LOAD TRANSFER

Inphase monitoring logic controls transfer and retransfer

of motor loads, so that inrush current s do not exceed

normal starting currents. It avoids nuisance tripping of

circuit breakers and mechanical damage to motor

couplings.

The Motor L oad 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

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 FEA TURE

Connect externalcircuits 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 amps 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 di sconnect control signal

and initiation of transfer is set on the controller with DIP

switch S2 (actuators 6, 7, 8) as shown below:

enable Actuator 6 on

disable Actuator 6 off

*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.
