Page 3: Description
3.0 D ESCRIPTION Detcon MicroSafe™ Model TP-524C, hydrogen sulfide sensors are non-intrusive “Smart” sensors designed to detect and monitor H2S in air. Ranges of detection are 0-20 ppm, 0-50 ppm, and 0-100 ppm. One of the primary features of the sensor is its method of automatic calibration which guides the user through each step via instructions dis- played on the backlit LCD. - Page 4 The base connector board is mounted in the explosion proof enclosure and includes: the mating connector for the control circuit, reverse input and secondary transient suppression, input filter, and lugless terminals for field wiring. 3.0.4 Explosion Proof Enclosure Detcon Model TP-524C Hydrogen Sulfide Sensor PG.4...

Calibration mode allows for sensor span adjustments. Unless otherwise specified, span adjustment is performed at 10 ppm H2S in air for the range 0-20 ppm, and 25 ppm H2S in air for the ranges 0-50 ppm and 0-100 ppm. “AUTO SPAN” Detcon Model TP-524C Hydrogen Sulfide Sensor PG.6... - Page 7 3.5.1 Field Wiring Table (4-20 m output) Detcon Model TP-524C solid state H2S sensor assemblies require three conductor connection between power sup- plies and host electronic controllers. Wiring designators are + (DC), – (DC) , and m (sensor signal). Maximum single conductor resistance between sensor and controller is 10 ohms.

Page 9: Pplication
This is usually true in instances where the gas sensor head must be mounted in a location that is diffi- cult to access. Such a location creates problems for maintenance and calibration activities. Detcon provides the TP- 524C sensor in a remote-mount configuration in which the sensor (Model TP-524C-RS) and the transmitter (Model TP-524C-RT) are provided in their own condulet housing and are interfaced together with a four conductor cable. -
Page 10: Start-Up
Remove the test gas and observe that the LCD display decreases to “0 PPM H2S”. Initial operational tests are complete. Detcon H2S gas sensors are pre-calibrated prior to shipment and will, in most cases, not require significant adjustment on start up. However, it is recommended that a complete calibration test and adjustment be performed 16 to 24 hours after power-up. - Page 11 In 3 second hold, the programming magnet is held in place over a switch location for 3 or more seconds.

To determine the current range setting follow the instructions given in section 3.8.
- Page 13 NOTE: Span gas bottles contain 0% humidity and this ultra-low humidity condition will cause inaccurate readings when used to calibrate a sensor. To prevent this error, Detcon prescribes the use of an In-Line Humidifying Tube, which adds the relative humidity to the span gas. The humidifying tube is not necessary when using a gas generat- ing calibration device that consists of pumped ambient air and an H2S generating source.

3. Check validity of cal gas using H2S pull tube or other means (must be H2S in air background). 4. Check for obstructions through s/s sinter element (including being wet). 5. Check sensor lot # and report to Detcon. Zero Fault Must recover to <10% of range before calibration cycle is complete and returns to normal operation. - Page 17 4. Check validity of cal gas (must be H2S in air background). 5. Check for obstructions through s/s sinter element (including being wet). 6. Check sensor lot # and report to Detcon. 7. Check area for presence of reducing gases such as Cl2 and ozone which may cause low readings.
