Sentry Instruction Manual - Version 6

To adjust the sensitivity apply 20 ppm hydrogen sulfide for five minutes for full stabilization. (Check that the voltage drops by at least .3 volts during this time.) Adjust the signal out value to .6 VDC using the range adjust potentiometer. Remove gas and verify that the voltage climbs to above 1.0 VDC in five minutes.

7.4.4 SENSOR REPLACEMENT

If either of the above adjustments cannot be completed successfully the sensor and/or electronics will require replacement. To check the sensor unplug it from the electronics and remove from the housing so that continuity and resistance tests can be made. Table 7-3 provides the pin out for the sensor assembly.

Hydrogen Sulfide Sensor

Wiring Pin-Out

1.Sensor Film resistance (grey wires) should be above 10K ohms.

2.Heater resistance (red wires) should be between 20 and 35 ohms.

3.Calibration switch (green wires) should be open in normal operation and should close when the calibration magnet is applied.

If the sensor fails any of these tests it should be replaced. If the sensor passes these tests the electronics are suspect and BOTH the sensor and electronics should be replaced. (The failed components should be returned to the factory for evaluation).

When a new sensor is installed the following actions should be taken:

1.Input new factors into controller. The factors are written onto the sensor connector label. (Three numbers: ###-###-###)

2.Make a preliminary power adjustment to insure heater is below 400 mW.

3.Force calibrate the sensor module.

4.Wait 24 hours for stabilization of the sensor film.

5.Make the power and sensitivity adjustments as described above.

6.Calibrate the sensor.

7.4.4.1 H2S MODULE HEATER VOLTAGES

Table 7-4 may be used during adjustment of Hydrogen Sulfide sensor heater voltages. Make small adjustments to the Heater Adjust potentiometer until the corresponding Heater Voltage and Heater Current readings are obtained. Both values are read as voltages.
