10-20 kW – INSTALLATION ASSISTANT:
Upon first power up of the generator, the display inter-
face will begin an installation assistant. The assistant
will prompt the user to set the minimum settings to
operate. These settings are simply: Current Date/Time
and Exercise Day/Time. The maintenance intervals
will be initialized when the exercise time is entered for
the first time (Figure 3.2).
The exercise settings can be changed at any time via
the "EDIT" menu (see Appendix, "Menu System").
If the 12 Volt battery is disconnected or the fuse
removed, the Installation Assistant will operate upon
power restoration. The only difference is the display
will only prompt the customer for the current Time
and Date.
if the installer tests the generator prior to instal-
lation, press the “enter” key to avoid setting
up the exercise time. this will ensure that when
the customer powers up the unit, he will still be
prompted to enter an exercise time.
note: the exerciser will only work in the auto mode
and will not work unless this procedure is performed.
the current date/time will need to be reset every time
the 12 Volt battery is disconnected and then recon-
nected, and/or when the fuse is removed.

to Select automatic operation

The following procedure applies only to those instal-
lations in which the air-cooled, automatic standby
generator is installed in conjunction with a transfer
switch. Transfer switches do not have an intelligence
circuit of their own. Automatic operation on transfer
switch and generator combinations is controlled by
circuit board action.
To select automatic operation when a transfer switch
is installed along with a home standby generator,
proceed as follows:

1. Check that the transfer switch main contacts are at

their UTILITY position, i.e., the load is connected to the

power supply. If necessary, manually actuate the switch

main contacts to their UTILITY source side. See Part 3

of this manual, as appropriate, for instructions.

2. Check that utility source voltage is available to transfer

switch terminal lugs N1 and N2 (2-pole, 1-phase transfer

switches).

3. Set the generator AUTO-OFF-MANUAL switch to its

AUTO position.

4. Actuate the generator main line circuit breaker to its “On”

or “Closed” position. With the preceding Steps 1 through

4 completed, a dropout in utility supply voltage below a

preset level will result in automatic generator cranking

and start-up. Following startup, the transfer switch will be

actuated to its “Standby” source side, i.e., loads powered
by the standby generator.

manual tranSFer to “StandBy” and

manual Startup

To transfer electrical loads to the “Standby” (generator)
source and start the generator manually, proceed as
follows:

1. On the generator panel, set the AUTO-OFF-MANUAL

switch to OFF.

2. On the generator, set the main line circuit breaker to it’s

OFF or “Open” position.

3. Turn OFF the power supply to the transfer switch, using

whatever means provided (such as a utility source line

circuit breaker).

4. Manually actuate the transfer switch main contacts to

their “Standby” position, i.e., loads connected to the

“Standby” power source side.

note: For instructions on manual operation of
transfer switches, see part 3.

5. On the generator panel, set the AUTO-OFF-MANUAL

switch to MANUAL. The engine should crank and start.

6. Let the engine warm up and stabilize for a minute or two

at no-load.

7. Set the generator main line circuit breaker to its “On”

or “Closed” position. The generator now powers the

electrical loads.

manual ShutdoWn and retranSFer

Back to “utility”

To shut the generator down and retransfer electrical
loads back to the UTILITY position, proceed as follows:

1. Set the generator main line circuit breaker to its OFF or

“Open” position.

2. Let the generator run at no-load for a few minutes, to cool.
3. Set the generator AUTO-OFF-MANUAL switch to OFF.

Wait for the engine to come to a complete stop.

4. Turn off the utility power supply to the transfer switch

using whatever means provided (such as a utility source

main line circuit breaker)

5. Manually actuate the transfer switch to its UTILITY

source side, i.e., load connected to the utility source.

6. Turn on the utility power supply to the transfer switch,

using whatever means provided.

7. Set the generator AUTO-OFF-MANUAL switch to AUTO.
