In case of alarm

Extinguish any naked flames.

Do not switch lights or electrical devices on or off.

Open all windows and door to increase ventalation.

•

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 reamins constant and the cause is not evident or not possible to eliminate turn off the emergency isolation valaves to the area

and contact your gas provider emergency line. They will advise accordingly.

Troubleshooting

The Problem

If the device does not start up.

If the Fault LED lights up, the system reports

an error status.

If the Over Load Probe LED lights up.

If the Over Load Battery LED lights up.

If the control unit is repeatedly issuing an

alarm.

If the control unit is issuing an alarm and

does not shut off the devices connected to

it.

If a 12Vdc solenoid valve is connected to the

BX308/xp, which does not work well

Check that the power supply is correctly connected. If powered by the battery, check that the

is power is

correctly connected.

Possible cause: The input current loop is interrupted or the sensor is not powered.

Solution: Check the connections between the sensor and the control unit for interruption. Also

check presence of a voltage around 12 VDC between the "+ V" and "GND" terminals of the

reference input.

Check that the power polarity has not been inverted, that no short-circuit is present, that the

sensors were not damaged during installation, that no excessive current absorption is present.

Check that the connection cables are not short-circuited, that the polarity has not been

inverted, or 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 sensors.

Check that the wiring is correct and that the jumper that carries power to the relay has

been set properly. All relays must be free from electrical power. Check the drawing of the

connections.

Direct connection of 12Vdc solenoid valves or sirens to the BX308xp is not permitted.

An external power unit must always be used. The BX308xp gives a max current of 200mA.
