Page 5: Introduction
Model TP-524D 1. Introduction 1.1 Description Detcon Model TP-524D hydrogen sulfide sensors are non-intrusive “Smart” sensors designed to detect and monitor H S in air. Ranges of detection are 0-20ppm, 0-50ppm, and 0-100ppm. The sensor features an LED display of current reading, fault, and calibration status. The Sensor is equipped with a standard analog 4- 20mA output. -
Page 6: Modular Mechanical Design
The sensor response is reversible and results in continuous monitoring of ambient air conditions. 1.2 Modular Mechanical Design The Model TP-524D Sensor Assembly is completely modular and is made up of four parts: 1) TP-524D Plug-in Transmitter 2) Field Replaceable H... -
Page 7: Figure 4 Field Replaceable H S Sensor
S gas sensor is a field proven, replaceable type sensor. It can be accessed and replaced in the field by removing the wiring from the connector PCB, and unthreading the Sensor from the junction box. The Detcon solid state H S sensor has an infinite shelf life and is supported by a 10 year, industry-leading warranty. -
Page 8: Installation
8. These sensors meet EN60079-0, EN60079-1. Calibration/Bump Test Following Ingress Protection Events Although the Model TP-524D/624D detector models are designed for IP 66 Ingress Protection, it is a mandatory requirement from the ISA 92.00.01-2010 Performance Standard that this device requires that a gas bump test or span calibration is performed shortly after any event where the conditions of IP66 level ingresses have been presented to the detector. -
Page 9: Sensor Placement
Painting sensor assemblies is prohibited. Although the sensor is designed to be RFI resistant, it should not be mounted in close proximity to high- powered radio transmitters or similar RFI generating equipment. TP-524D Instruction Manual Rev. 0.8 Page 5 of 37... -

500 = 3 Ethanol 500 = 5 NOTE: The Detcon MOS Sensor Cell can be damaged to the point of non-functioning if the unit is left off power and in the presence normal air levels of moisture for periods exceeding 8 hours. -
Page 11: Mounting Installation
The TP-524D should be vertically oriented so that the sensor points straight downward. The explosion-proof enclosure or junction box would then typically be mounted on a wall or pole (See Figure 7). Detcon provides a selection of standard junction boxes in both Aluminum and Stainless Steel. -

Observing correct polarity, terminate the 3-conductor 4-20mA field wiring (DC+, DC-, and MA) to the sensor assembly wiring in accordance with the detail shown in Figure 9. c) Trim all exposed wire leads if they are not permanently landed in the terminal block. TP-524D Instruction Manual Rev. 0.8 Page 9 of 37... -
Page 14: Initial Start Up
Upon completion of all mechanical mounting and termination of all field wiring, apply system power 24VDC (typical) and observe the following normal conditions: a) TP-524D display reads “0”, and no fault messages are flashing. b) A temporary upscale reading may occur as the sensor heats up. This upscale reading will decrease to “0”... - Page 15 Remove test gas and observe that the display decreases to “0”. Initial operational tests are complete. Detcon H S gas sensors are factory calibrated prior to shipment, and should 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.

NOTE 4: 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 a 24” flexible In-Line Humidifying Tube, which adds the relative humidity to the span gas. - Page 20 NOTE 1: If the sensor fails the minimum signal change criteria, a “Range Fault” will be declared and a “Fault Detected” message will be displayed alternately with the sensor’s current reading. The 4-20mA output will be taken to 0mA. TP-524D Instruction Manual Rev. 0.8 Page 16 of 37...

Page 24: Set Range
Set Heater Power is used to set the each H S sensor to the optimum operating temperature. This function is performed during factory calibration of each TP-524D sensor assembly, and is not necessary during installation. However, it is necessary to perform in the field if the plug-in H S sensor is replaced, mounted remotely from the Transmitter Module, or if the Restore Factory Defaults function has been executed. -

Page 26: Alarm 1 And 2 Settings
3.5.7 Alarm 1 and 2 Settings The TP-524D has the ability to set alarm levels that are displayed on the front of the sensor via the LED’s ALM 1 and ALM 2. These alarm LEDs can be set as latching or non-latching. In non-latching mode, the LED is deactivated as soon as the sensor alarm condition is cleared. -
Page 27: Fault Settings
Model TP-524D 3.5.8 Fault Settings The TP-524D Fault LED can be configured to change state when the sensor experiences a fault condition. This LED can be configured as either latching or non-latching. In non-latching mode, the LED is deactivated as soon as the fault condition is cleared. - Page 28 Model TP-524D Fail-Safe/Fault Supervision Model TP-524D MicroSafe™ sensors are designed for Fail-Safe operation. If any of the diagnostic faults listed below are active, the sensor display will scroll the message “Fault Detected” every 60 seconds during normal operation. At any time during “Fault Detected” mode, holding the programming magnet over PGM1 or PGM2 for 1 second will display the active fault(s).
- Page 29 ITM display. If a Loop Fault occurs, the 4-20mA signal will be set at 0mA until the fault condition is resolved. If the 4-20mA current loop is still out of tolerance, contact Detcon at Service@detcon.com, or contact Detcon customer service.
