System Setup

You must perform the following before operating the system:

• If generator is installed in an area regularly subjected

to temperatures below 4°C, select a 50 second warm

up time by moving jumper installed on JP2 from ‘20’

position to ‘50’ position.

• Set the DPSW1 and DPSW2 dipswitches on the control

module to match the KW rating of the Home Standby

Generator set as described in Setting Dipswitches.

Setting Dipswitches

Dipswitches are used to adjust control board operation

based on generator capacity and fuel source. Sum of DSPW1

and DPSW2 are set to correspond to system kW rating.

Dipswitch DPSW1 has units of 1,000 Watts; Dipswitch

DPSW2 has units of 10,000 Watts.

IMPORTANT: Set only one switch to “On” position on each

dipswitch.

NOTICE

Use extreme caution when setting dipswitches or

damage to control board will result.

Use a pencil or small piece of plastic to set the dipswitch.

NEVER use a screwdriver or any type of metal object to

set dipswitches.

•

The “On” position for the dipswitches is the switch number

ON THE CONTROL BOARD, not on the switch. For example,

on a 27,000 Watt generator that runs on natural gas (NG), set

DPSW2 dipswitch 20 to “On” position. Set DPSW1 dipswitch

7 to “On” position. 20,000 plus 7000 equals 27,000 Watts.

Supervisory Control Wiring

1. Terminal strip on control module in transfer switch

has four connections for customer use. There are two

sets of “Normally Closed” contacts available. They will

be activated when generator power is required. These

can be used for supervisory control of large connected

loads on generator. Loads will be allowed to operate if

there is enough generator power available.

NOTE: There are two wireways provided to keep the

supervisory loads separated from each other.

2. Terminals “A-A” on control module are rated for

24 VAC and air conditioner contactor control. Contacts

are connected in series with the air conditioner

contactor control circuit.

3. Terminals “B-B” on control module are rated for 5 Amp

250 VAC and installer supplied contactor to control a

large load. Example: electric hot water heater. Contacts

are connected in series with the contactor control circuit.

4. Tighten all wire connections/fasteners to proper torque.

See inside transfer switch enclosure for proper torque

values.
