Functional Testing of the Sensor

WARNING: DO NOT use a gasoline soaked rag or a container partially filled with gasoline to test sensor. The raw gas could ignite resulting in serious injury. In addition, the isolated high concentration of fumes may damage the sensor and render it inoperative.

To TEST SENSOR use butane lighter with the striker wheel removed. Hold the lighter to the sensor and press down on the lever to release the Butane. In three to four seconds the warning light will come on. In about ten seconds the alarm horn will sound. Remove lighter from the sensor. Mute the alarm horn and within several seconds the warning light will shut off.

Whenever the S-2A alarms, the horn may be muted with the “MUTE” button, but THE PROBLEM SHOULD NOT BE CONSIDERED CLEARED UNTIL THE ALARM LIGHT GOES OUT

Sensor Fault Detection

Should the unit determine that either of the sensors is faulty or disconnected, the corresponding indicator will change to amber and the horn will sound, Check that the sensor is connected and that wiring has not been frayed or cut. Should this condition persist, the sensor has been damaged and must be replaced.

Unit Fault Detection

Should an internal failure occur, the unit fault light will display amber and the horn will sound. Should this occur, return the display to the manufacturer for repair.

Nuisance Alarms

The sensor used for the S-2A is sensitive to hydrocarbons- an alarm may be triggered by the use of other chemicals such as cleaners, paint, polish, etc… The sensors will also detect hydrogen fumes from an overcharged battery. If no gasoline fumes are present, check for recent use of cleaners, fiberglass repairs, strong adhesives, etc… If none of these are present, the sensor may have been damaged and will need replacement.

WARNING:

The S-2A has been designed to alarm nominally at 20% of the LEL (Lower Explosive Limit) of Propane/CNG. Implement immediately the following procedures in the event of an alarm. Shut down all appliances. Manually shut oft the source of Propane/CNG. Turn off all electrical circuits EXCEPT circuits, which operate blowers and/or exhaust fans. Remove all personnel from the area. Ventilate the area; turn on exhaust fans and open windows, hatches, etc… Carefully check all fuel lines, tanks and fittings to locate the leak. Have the problem repaired by qualified personnel.

Maintenance

The S-2A requires very little maintenance. Periodically examine the sensors for contamination or damage. Check that sensor wires are not frayed, pinched, or cut. Test the operation of both sensors and display frequently. Do NOT expose sensors to liquids or chemicals.

When cleaning, seal off the sensor(s) with a plastic covering. Harsh chemicals may damage the sensor. Keep sensor(s) sealed until the compartment has been completely ventilated.

CAUTION: DO NOT FORGET TO REMOVE SENSOR COVERINGS OR THE S-2A WILL NOT OPERATE CORRECTLY.
