2.10 ENGINEERED TRANSFER SWITCH

(2-WIRE START GTS MODE)

When required, the pre-packaged standby generator can be installed with an engineered W Type transfer switch which controls utility voltage sensing, weekly exercising and load transferring.

When Position 2 of the eight-position DIP switch, which is located on the generator circuit board (See Figure 3.2), is in the ON position then utility voltage sensing, weekly exercising and load transferring is under the control of the Engineered W Type transfer switch (GTS Mode).

Generator DIP Switch Position 2 ON = 2-Wire Start GTS Mode

•The generator control board will NOT monitor the utility.

•The generator control board will NOT perform a weekly exercise. (The five red LEDs will flash one at a time in GTS mode.)

•The generator control board will NOT activate the transfer output.

The generator control board WILL monitor all engine conditions and shut down on all the faults listed in this document.

For the W Type transfer switch to control utility volt- age sensing, weekly exercising and load transferring, suitable wiring must also be connected from the transfer switch 178 and 183, 2-Wire Start terminals to the corresponding generator 178 and 183 2-Wire

Start terminals. Recommended wire gauge sizes for the 2-Wire Start wiring depend on the length of the wire (see wiring length chart).

Route the 2-Wire Start control wires through suitable, approved conduit which is separate from the AC power leads. Connection of wire 178 to wire 183 by relay contact closure action (volt free switch contacts) in the transfer switch must result in generator engine cranking and startup (See Figure 2.4).

Do NOT connect battery voltage, utility voltage

!(N1/N2) or load voltage (T1/T2) to either the

178 or the 183 2-Wire start terminals as this will damage the generator control board.

In order for the generator battery charging function to work, it is necessary to provide a 5 amp fused 240Vac utility source connection from the transfer switch main N1 and N2 terminals to the generator control panel N1 and N2 terminals (See Figure 2.4).
