COsense®

Carbon Monoxide (CO) Detection

and Shut-off System (if equipped)

The COsense module monitors for the accu-

mulation of poisonous CO gas found in engine

exhaust when the generator is running. If

COsense detects increasing levels of CO gas,

it automatically shuts off the engine. COsense

only monitors when the engine is running.

Generators are intended to be used outdoors,

far from occupied buildings and the exhaust

pointed away from personnel and buildings.

However, if mis-used and operated in a loca-

tion that results in the accumulation of CO, like

indoors or in a partially enclosed area,

0000.0

000205

000203

000204

8 Owner’s Manual for Portable Generator

COsense shuts off the engine, notifies the

user of what has happened and directs the

user to read the instruction action label for

steps to take. See Figure 2-7. COsense is not

a substitute for an indoor carbon monoxide

alarm.

See Figure 2-8. After a shut-off, a blinking

RED light in the COsense badge on the side

of the generator provides notification that the

generator was shut off due to an accumulating

CO hazard. The RED light will blink for at least

five minutes after a CO shut-off. Move the

generator to an open, outdoor area and point

the exhaust away from people and occupied

buildings. Once relocated to a safe area, the

generator can be restarted and the proper

electrical connections made to supply electri-

cal power. The RED light will stop blinking

automatically upon engine re-start. Introduce

fresh air and ventilate the location where the

generator had shut down.

See Figure 2-8. If a COsense system fault has

occurred and no longer provides protection,

the portable generator is shut off automatically

and the YELLOW light will blink for at least

five minutes in the COsense badge to notify

the user of the fault. The COsense module

can only be diagnosed and repaired by a

trained technician at the dealer. The generator

can be re-started, but may continue to shut-

off.

COsense will detect the accumulation of Car-

bon Monoxide from other fuel burning sources

such as engine powered tools or propane

heaters used in the area of operation. For

example, if another generator is used and the

exhaust is pointed at a COsense equipped

generator, COsense may initiate a shut-off

due to rising CO levels. This is not an error.

Hazardous Carbon Monoxide has been

detected. The user must take action to move

and re-direct these devices to better dissipate

Carbon Monoxide far away from personnel

and occupied buildings.
