CO SENSOR

CO SENSOR
The CO Sensor monitors for the accumulation of poisonous carbon monoxide gas around the generator when the engine
is running. If increasing levels of CO gas are detected, the CO Sensor automatically shuts down the engine.
The CO Sensor will also detect the accumulation of carbon monoxide from other fuel burning sources used in the area of
operation. For example, if the exhaust of fuel burning tools is pointed at a CO Sensor-equipped generator, a shut-off may
be initiated due to rising CO levels. This is not an error. Hazardous carbon monoxide has been detected. Move and
redirect any additional fuel burning sources to dissipate carbon monoxide away from personnel and occupied buildings.
Note: Remote start-equipped generators must be restarted with the START/STOP button on the control panel after an
automatic shut-down occurs.
Generators are intended to be used outdoors, far from occupied buildings and the exhaust pointed away from personnel
and buildings. If misused and operated in a location that results in the accumulation of CO, like in a partially enclosed area,
the CO Sensor shuts off the engine, notifies the user with a RED indicator light, and directs the user to read the Action
Label for steps to take. The CO Sensor DOES NOT replace carbon monoxide alarms. Install battery-powered carbon
monoxide alarm(s) in your home.
CO SENSOR INDICATOR LIGHTS
RED
Carbon monoxide accumulated around the generator. After shut-off, the RED indicator light in the CO Sensor area of the
control panel will flash to provide notification that the generator was shut-off due to an accumulating CO hazard. The RED
light will flash for at least five minutes after a CO shut-off.
Move the generator to an open, outdoor area far away from occupied spaces with exhaust pointed away. Once relocated to
a safe area, the generator can be restarted. Introduce fresh air and ventilate the area where the generator had shut down.
YELLOW
A CO sensor system fault occurred. When a system fault occurs, the generator is automatically shut down and the
YELLOW indicator light in the CO auto-shutoff area of the control panel will flash to provide notification that a fault has
occurred. The YELLOW light will flash for at least five minutes after a fault. The generator can be re-started, but may
continue to shutoff. A CO sensor fault can only be diagnosed and repaired by an authorized Pulsar service center.
