Important Notes

IMPORTANT: Assembly / maintenance of the appliance must be carried out by qualified personnel and in

accordance with applicable laws and regulations.

The manufacturer assumes no responsibility for the use of products that have to comply with particular

environmental and / or installation standards.

IMPORTANT: Before connecting the equipment, it is recommended that you read the instruction manual

carefully and keep it for future reference.

Troubleshooting

If the device does not start up.

Check that the 12/24 VDC power is present, and that positive and negative polarity has not been inverted.

If the Fault LED condition occurs.

Check that the cables are connected according to the drawing, and that the wire isolation sheath has not been pinched.

Check the voltage at the terminals 1-2. It must be higher than 11 VDC and lesser than 25VDC.

Check the voltage at the terminals 2-3. It must be from a minimum of 0.8 VDC to a maximum of 1.1 VDC.

CO233/A - Carbon Monoxide Gas Sensor

GREEN

When the display is Green in colour with a gas

concentration in parts per million (ppm). This indicates

that the toxic gas threshold has not been exceeded.

WHITE

When the display shows the White colour and text 'Con'

is shown. It indicates that the testing instrument is

connected.

YELLOW

When the display shows the Yellow colour and text

'FAU' is shown. It indicates a sensor fault. This

immediately triggers the fault relay.

The position of the sensor is a crucial factor for its correct

functioning. The sensor must be placed at a height of:

160 cm from the lowest point on the floor up to 30 cm

from the ceiling, and in all cases at an average height in

the monitored area.

The sensor must not be placed near the following:

furnaces, fuel-burning kitchen appliances, fireplaces,

ranges, suction fans, and should not be affected by

smoke, vapour as these could distort its measurement.

The sensor must not be placed away from sources of

heat, suction fans, ventilation fans, windows, doors, etc.

that can distorting the detection, should be placed away

from heat sources and away from aspirators or fans.

MAGENTA

When the display shows the Magenta colour and text

'StA' is shown. It indicates that the maximum average

concentration to which an unprotected worker may be

exposed in any ﬁfteen-minute interval during the day

has been detected (200ppm) and the main alarm relay

has triggered.

CYAN

When the display shows the Cyan colour and text '8hA'

is shown. It indicates the maximum average

concentration to which an unprotected worker may be

exposed in any eight-hour interval during the day has

been detected (30ppm) and the main alarm relay has

triggered.

RED

When the display shows the Red colour and a gas

concentration in ppm is shown. It indicates the toxic

gas threshold has been reached or passed. If the 300

ppm has detected the main alarm relay is triggered

immediately.
