Transfer Switch

Plant Exerciser (B1–B2)

The Plant Exerciser option is a seven-day clock that provides for automatic test operation of the generator set at pre-selected intervals. The clock is powered by a fused circuit from control transformer XFMR3. The Plant Exerciser option is used in conjunction with contacts to initiate engine starting without a load transfer, option B1. Option B2 includes a selector switch to simulate a power failure with or without a load transfer.

Refer to section 8, pages 14-15, for instructions to program the Plant Exerciser timer.

Remote Test (R7)

This option provides terminal points for the connection of remote devices that are normally closed and wired in series with the TEST push button. An open circuit simulates failure of the normal source and initiates transfer to the emergency source.

Selector Switch (R2–R4)

Selector switches are available to set the transfer switch for testing, automatic or manual mode, and to test start the engine for troubleshooting and maintenance. Selector switches with an OFF position, option R2, include an OFF indicating light (PL4, white). Switches with a TEST position initiate a load transfer.

NEUTRAL POSITION TIME DELAY (N)

When the normal source contacts open, the NEUTRAL POSITION TIME DELAY starts. The timer circuit on the TCR board, temporarily disconnects the power source to the switching mechanism while the automatic transfer switch is in the neutral position (normal and emergency source contacts open). The adjustable timer is usually set for three seconds. The red START DELAY LED indicates the timer is counting. After the delay, the green END DELAY indicates the TR (timer relay) is energized to reconnect power to the switching mechanism.
