Troubleshooting

The Problem

The device does not start up

The FAULT LED lights up

The OVERLOAD SENSOR LED lights up

The OVERLOAD BATTERY LED lights up

The control unit is repeatedly issuing an alarm

The control unit is issuing an alarm and does not

shut off the devices connected to it

A 12V DC solenoid valve, which does not work well, is

connected to the BX150

If you are experiencing difficulties, having made the checks listed above call Duomo on 01905 797989 for

technical assistance.

In case of alarm

Extinguish any naked flames.

Do not switch lights or electrical devices on or off.

Open all windows and doors to increase ventilation.

If the 'ALARM' LED is off the levels of gas have dropped. A responsible, qualified person is now safe to find the cause of

the alarm.

If the alarm sound remains constant, and the cause is not evident or possible to eliminate turn off the emergency

isolation valves to the area and contact your gas provider emergency line. They will advice accordingly.

The Solution

Check that the 230V mains power is correctly

connected. If powered by the battery, check that the

12V DC power is correctly connected.

Check that the connecting cables from the BX150 to

the sensors are intact, that the sensors are properly

powered and that the signal cable is correctly

connected.

Check that;

- the power polarity has not been inverted

- that no short-circuit is present

- that the probes were not damaged during

installation, that no excessive current absorption

is present

Check that the connection cables are not

shortcircuited, that the polarity has not been

inverted and that the battery is not damaged.

Check that there are no gas leaks. If the alarm signal

and the FAULT indicator light turn on together, check

the sensor.

Check that the wiring is correct and that the DIP

switch has been set properly. All relays must be free

from electrical power. Check the drawing of the

connections.

Direct connection of 12V DC solenoid valves or sirens

to the BX150 is not permitted. An external power

unit must always be used. The BX150 gives a

maximum current of 50mA.
