OPERATING INSTRUCTIONS

When power is first applied the power light should illuminate immediately. The A1 and A2 lights of semiconductor sensors will illuminate within a few seconds and will be ready to be reset after a few minutes, provided the sensors are in clean air. The alarm lights and relays latch and the reset switch must be pressed to clear any alarms.

The gas valve can be operated by pressing the “gas on” button. The gas valve will de- energise automatically if the A1 alarm level is reached or if the power supply to the unit is removed. The valve can be turned off manually by pressing the “gas off” switch.

The output functions can be easily tested by pressing the “alarm test” button. If the “alarm accept” button is pressed any sounders or beacons connected will be muted.

When the input supply drops so low as the control unit cannot function correctly the low voltage light will illuminate and the fault relay will activate.

Engineers override: should be used with caution as all ALARMS are disabled for a period of approximately 30minutes. A hidden switch is located to the left of the reset switch. Pressed through the front panel using a small screwdriver all Alarms are Isolated and the Fault Buzzer sounds. Operate the hidden switch to the right of the Reset switch (keeping it pressed for several seconds) and all Alarms will be returned to the operational state and the Fault Buzzer will silence.

CALIBRATION

Before dispatch the alarm levels are approximately set for the target gas (if stated with order) or set to 25% and 50% LEL butane so that a measure of immediate protection is obtained once correct operation has been ensured.

Once the sensors and control unit have been in operation for a minimum of 24 hours calibration can be attempted. Calibration should be repeated at least every twelve months with regular checks in between.

Calibration must take place in a clean air condition to ensure accuracy.

Semiconductor sensors:

1.Immerse the sensor in the correct concentration for the A1 alarm, if using a continuous flow do not use a flow rate of above 0.3L/min.

2.After allowing the sensor time to settle (10-20 seconds) adjust the appropriate potentiometer located under the A1 light, accessed through the front panel. Rotating clockwise increases sensitivity until the A1 light just illuminates, if the light comes on prematurely wind anticlockwise whilst continuously pressing the reset switch until the light goes out and then clockwise until it just illuminates.

3.Immerse the sensor in the correct concentration for the A2 alarm, if using a continuous flow do not use a flow rate of above 0.3L/min.

4.After allowing the sensor time to settle (10-20 seconds) adjust the appropriate potentiometer located under the A2 light, accessed through the front panel. Rotating clockwise increases sensitivity until the A2 light just illuminates, if the light comes on prematurely wind anticlockwise whilst continuously pressing the reset switch until the light goes out and then clockwise until it just illuminates.

Repeat for all semiconductor sensors fitted.
