OPERATION

Automatic Operation Sequence

The generator’s control board constantly monitors utility

voltage. Should utility voltage drop below a preset level, the

control board signals the engine to crank and start. When

the utility voltage is restored above a preset voltage level,

the engine is signaled to shut down. The system operation

is not adjustable and is sequenced by sensors and timers

on the control board as follows:

Utility Voltage Dropout Sensor

• This sensor monitors utility source voltage.

• If utility source voltage drops below 70% of the nominal

supply voltage, the sensor energizes a 3 second timer.

The timer is used to sense low voltage conditions.

• Once the time has expired, the engine will crank and

start.

Engine Cool-Down Timer

When utility power is sensed and the load transfers to the

utility source, the engine will go into a cool down period as

described below:

• If the generator has run for MORE than 5 minutes, once

the utility transfer occurs, the engine will continue to run

for about 1 minute before shutting down.

• If the generator has run for LESS than 5 minutes, once

the utility transfer occurs, the engine will continue to run

until 5 minutes has elapsed before shutting down.

Exercise Timer

The generator is equipped with a weekly exercise timer.

During the exercise period, the generator runs for 20

minutes and then shuts down.

The generator does not supply power to the home

during the exercise cycle. The control panel displays

“GENERATOR READY” during the exercise cycle.

The generator is set to run the exercise cycle on Tuesday

at 2:00 PM. To change exercise cycle timer settings refer to

the General Set-up Screen flow chart in the Menu section.

equipped with sensors that automatically shut down the

generator in the event of potentially damaging conditions,

such as low oil pressure, high temperature, overspeed, or

other conditions.

CAUTION

Auto start of Machinery - Installing the

15 Amp fuse could cause the engine to crank

and start at any time without warning resulting in

minor to moderate injury.

• Do remove the 15A fuse before maintaining

and/or servicing generator.

DO NOT

• Do not reinstall 15A fuse until after

maintaining and/or servicing generator

MAINTENANCE

NOTICE

Contact a skilled person for service code repairs/

maintenance

The generator’s control board displays service codes. The

service code descriptions are listed below:

Low Battery Voltage: This condition occurs if the battery

voltage drops below the preset value. This condition may

be caused by a faulty battery or battery charge circuit. See

Battery Charge Circuit.

Under Voltage: This condition occurs if the generator

output voltage is less than the preset value. This condition

may be caused by a restriction in the fuel ow, the electronic

governing system not functioning properly, a broken or

disconnected signal lead, a failed alternator winding, the

control board circuit breaker is open or the generator is

overloaded.

Over Voltage: This feature protects devices connected to

the transfer switch by shutting the generator down if the

generator output voltage is greater than the preset value.

This condition may be caused by a failed voltage regulator,

alternator excitation circuit or a load imbalance.

Low Oil Pressure: The unit is equipped with an oil

pressure switch that uses normally closed contacts held

open by engine oil pressure during operation. The switch

contacts will close and the engine will shut down if oil

pressure drops below the rated value. This condition may

be caused by low oil volume.

Engine Does Not Start: This feature prevents the

generator from damaging itself if it continually attempts to

start despite another problem, such as no fuel supply. Each

time the system is directed to start, the unit will crank for 10

seconds, pause for 10 seconds, and repeat. If the system

does not begin producing electricity after approximately 2

minutes, the unit will stop cranking. The most likely cause

of this problem is no fuel supply or incorrect fuel selector

setting.

Generator Sense Fault: This fault will occur if the

generator is in the o state and the control panel measures

a signal from the generator output.

Low Frequency: This feature protects devices connected

to the transfer switch by shutting the generator down if the

engine runs slower than 45 Hz for 3 seconds. This condition

may be caused by a failed engine component, electronic

governor system, or excessive loads on the generator.

Engine Overspeed: This feature protects devices

connected to the transfer switch by shutting the generator

down if the engine runs faster than 55Hz for 3 seconds. This

condition may be caused by a problem within the electronic

governor system.

High Oil Temperature: The unit is equipped with an oil

temperature switch that uses normally open contacts. The

contacts will close and the engine will shut down if the

temperature exceeds the rated value. This condition may be

caused by running the generator with the panels removed,

the roof open, an obstructed air inlet or exhaust port, or

debris in the engine compartment.

Transfer Switch Service Code (if equipped): This feature

senses an open condition in the transfer switch circuitry.

This condition may be caused by a blown fuse in the

transfer switch.

Battery Charge Circuit: This feature senses an open

condition in the battery charge circuitry. This condition may

be caused by a blown fuse in the control panel.

Reset Service Code Detection System

The service code detection system must be reset each time

it activates. Contact a skilled person for technical problems

associated with Service Code Detection System.

To reset code detection system:

1. Open roof of generator.

2. Set generator’s circuit breaker to its OFF position.

3. Remove 15A fuse from control board. Wait 30 seconds.

Reinstall fuse.

4. Press and hold the control board AUTO button. Wait

30 seconds to allow generator to start as conditions

warrant.

5. Set generator’s circuit breaker to its ON position.

6. Close and secure roof with keys.
