Equipment Description

The transfer switch is designed to transfer selected loads

found in normal residential installations to generator power

in the event of a utility power failure. The load is connected

either to utility power (normal) or home standby power

(generator). The transfer switch monitors utility and generator

voltages and will automatically connect to the appropriate

source of power.

Major components of the transfer switch are a 2 pole

double throw transfer switch, control circuit board, fused

utility terminals and interconnecting wiring. The control

board also has two inputs for current transformers that

sense generator current. These components are housed in

a NEMA 3R enclosure that is suitable for both indoor and

outdoor installations.

The transfer switch is solenoid-operated from utility or

generator inputs and contain suitable mechanical and

electrical interlock switches to eliminate the possibility of

connecting the utility service to the generator output. It

has ratings capable of switching full utility power into the

residence. In addition, a manual override lever is provided for

the transfer function.

The control board has active circuits sensing utility and

generator voltages. It creates a signal for generator start-up,

switch transfer and retransfer when utility is restored. The

control board also contains red and green LED’s indicating

the power sources available and two relay operated contacts

that provide supervisory control of external loads.

System Setup

You must perform the following before operating the system:

• If generator is installed in an area regularly subjected

to temperatures below 40°F (4°C), select a 50 second

warm up time by moving jumper JP2 (A) installed

on transfer switch control board from ‘20’ position to

‘50’ position.

• Set the DPSW1 (B) and DPSW2 (C) dipswitches

on the transfer switch control board to match the

kW rating of the standby generator, as described in

Setting Dipswitches.

Setting Dipswitches

Dipswitches are used to adjust control board operation

based on generator capacity. DPSW1 and DPSW2 switches

are set to correspond to total system kW rating. Dipswitch

DPSW1 (B) has units of 1,000 watts; Dipswitch DPSW2 (C)

has units of 10,000 watts.

Set dipswitches with utility and generator power removed

from the transfer switch to ensure proper control system

operation. If dipswitches are set when power is present at

transfer switch, a power reset needs to be performed before

the new dipswitch settings will take effect. Power reset is

when all power is removed from the transfer switch and then

reintroduced after 30 seconds.

NOTICE An FC_8 will occur on standby generator control board

if dipswitches are not properly established as noted above.

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

THE TRANSFER SWITCH CONTROL BOARD, not on the

switch. For example, for an 18,000 watt generator, set DPSW2

dipswitch 10 to “ON” position. Set DPSW1 dipswitch 8 to “ON”

position. 10,000 plus 8000 equals 18,000 watts.

Set only one

switch to “ON” position on DPSW1 and DPSW2.

Refer to following chart for proper switch selection(s).

NOTICE

Air density is less at high altitudes, resulting in

less available engine power. Specifically, engine power will

decrease 3.5% for each 1,000 feet (300 meters) above sea

level and 1% for each 10° F (5.6°C) above 77°F (25°C).

Generators located in these conditions must have the transfer

switch programmed appropriately for this power decrease.

System Test

With the generator system switch in AUTO, turn the circuit

breaker feeding the transfer switch to the OFF position. After

a few minutes the generator will start and the transfer switch

will transfer essential loads to generator power.

To return to utility power, turn the circuit breaker feeding the

transfer switch ON.

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.
