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,
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
a substitute for an indoor carbon monoxide
alarm.

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

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.
