2 Product Description
2.1 Introduction
Tek-Trol’s Explosion-proof Temperature Transmitter is a microprocessor based temperature transmitter that has temperature sensors such as Thermocouple, RTD, mV, and Resistance. The Tek-Temp 2100A is explosion-proof type and has high precision, better reliability and uses a remote communication system. This transmitter is enabled in HART communication with Host, a HHT (HART Hand-Held Terminal), or PC Configurator. The transmitter has a number of variables in host that can be changed, configured, and calibrated by users with the help of HHT.
2.2 Measuring Principle
A temperature transmitter is typically connected to a 24VDC power source. The temperature sensor such as RTD or Thermocouple measures the temperature of the medium. The transmitter first modifies the output signal of the sensor into a standard format with the help of Signal Conditioning process such as Amplification, Isolation, Filtering, Linearization, and Excitation. The transmitter amplifies and converts the output to a high-level analog signal, usually a standard 4-20mA signal. It then transmits the amplified signal to the control device by means of long cable runs.

3.1 Selection of Installation of Locations
The transmitter is designed to withstand severe environmental conditions. However, to ensure stable and accurate operation for many years, the following precautions must be observed when selecting an installation location:
x Ambient Temperature
x Ambient Atmosphere
x Shock and Vibration
x Installation of Explosion-Protected Transmitters
x Select a location where the maintenance of transmitter can be conducted easily.
Avoid locations subject to wide temperature variations or a significant temperature gradient. If the location is exposed to radiant heat from plant equipment, provide adequate insulation or ventilation
Avoid installing the transmitter in a corrosive atmosphere. If the transmitter must be installed in a corrosive atmosphere, there must be adequate ventilation as well as measures should be taken to prevent intrusion or stagnation of rainwater in conduits. Moreover, there should be appropriate ventilation preventing corrosion by rain gathered on conduit
Select an installation site that experiences minimum shock and vibration (although the transmitter is designed to be relatively resistant to shock and vibration).
Explosion-protected transmitters can be installed in hazardous areas according to the gas types for which they are certified.
3.2 Waterproofing of Cable Conduit Connections
Apply a non-hardening sealant (silicone or tape, etc.) to the threads to waterproof the transmitter cable conduit connections.
3.3 Restriction on Use of Radio Transceivers
Although the transmitter has been designed to resist high frequency electrical noise, if a radio transceiver is used near the transmitter of its external wiring, the transmitter may be affected by high frequency noise pickup. To test for such effects, bring the transceiver in use slowly from a distance of several meters from the transmitter, and observe the measurement loop for noise effects. Thereafter, always use the transceiver outside the area affected by noise.

4. After completing the test and being very careful not to touch exposed conductors, disconnect the insulation tester and connect a 100kW resister between the grounding terminal and the short-circuiting SUPPLY terminals. Leave this resistor connected for at least 3-seconds to discharge any static potential. Do not touch the terminal while it is discharging.
1. Short-circuit the +ve and -ve SUPPLY terminals in the terminal box.
2. Turn OFF the dielectric strength tester. Then connect the tester between the shorted SUPPLY terminal and the GROUNDING terminal. Be sure to connect the grounding lead of the dielectric strength tester to the ground terminal.
3. Set the current limit on the dielectric strength tester to 10mA, then turn ON the power and gradually increase the tester voltage from '0' to the specified voltage.
4. When the specified voltage is reached, hold it for 1-minute.
5. After completing this test, slowly decrease the voltage to avoid any voltage surges.

4.1 General Considerations
This transmitter uses temperature sensors. It transfers electrical signal minutely to 4 to 20mA analog signal. Thus, mount the transmitter close to the process and use a minimum of sensor length to achieve best accuracy. However, keep in mind the need for easy access, safety of personnel, practical field calibration, and a suitable transmitter environment. In general, install the transmitter so as to minimize vibration, shock, and temperature fluctuations.
4.2 Electrical Considerations
The transmitter housing composes of two parts. One side is electronics circuit, and other side is terminal block. The terminal block side is the transmitter's front side and is indicated as "Field Terminal" in transmitter’s external housing. Open this side's housing cover; the terminal block in-housing is inside. Consider the terminal block polarity while connecting the transmitter's power supply.

4.9 Environmental Considerations
4.9.1 Effect of Ambient Temperature
You have to install at -40 range. If predicted heat exceeds or is equivalent to the ambient temperature range limit, consider an additional method to cut-off the process heat.
4.9.2 Environment Having Toxic Material/ Moisture
Housing of the Tek-Temp 2100A can be protected against moisture or toxic material. The electronic circuit side is separated from terminal side. When the O-ring seal cover is covered, it is safe. However, drips could penetrate the housing of transmitter through the conduit pipeline. Therefore, the transmitter should be set up over the position of conduit pipe to prevent dripping.
4.9.3 Installation in a Dangerous Place
The transmitter is designed with explosion-proof housing. The installation environment of the transmitter must confirm to explosion-proof specifications.

Tek-Temp 2100A Explosion-proof Temperature Transmitter automatically and continuously performs self-diagnostic routines. If the self-diagnostic routines detect a failure, the transmitter drives its output outside of the normal saturation values. The transmitter will drive its output low(down) or high(up) based on the position of the failure mode alarm jumper. The table below shows the output values.
The Fail Mode Select Jumper switch is in LCD module and main CPU module and Jumper Switch Line is connected circuital. In the case of no LCD module, we can use CPU module's Fail Mode Select Jumper switch and in the case of LCD module we can use the LCD module's Jumper switch. In this case, the CPU module selected is "Down" side. Not selected and we can select "Down" side.

5.6 Configuration of Zero and Span Procedures
ZERO and SPAN Buttons are visible when the nameplate of the transmitter is opened. For the previous version of this transmitter, ZERO, SPAN, ZERO TRIM and ZERO ADJ. functions were supported using ZERO / SPAN buttons; from Version 58, the Units, Range, Damping, LCD decimal set functions are included. The procedure has also changed as below:
However, the ZERO and SPAN set functions are the same as before the revision of Version
58. Using functions which supported by buttons:
x Zero/Span button mounted in the transmitter x HHT Configurator by HART Communication
Zero/Span configuration process by Zero/Span button of the transmitter:
1. Release both sides bolts of the nameplate in the upper part of the transmitter and push down to the right of the nameplate. This will show the Zero/Span button.
2. Zero Configuration
Set the current process value for Lower Range Value (4 mA). Put necessary pressure on the Zero button for 10-seconds and push the Zero button for 5-seconds. This will display “Zero” in the LCD window. After checking this message, remove the finger from the button. Press the button for 3 seconds with 1- second intervals. This will display “-ZE-”in the LCD window. When this message is displayed all zero configurations are complete. If the procedure has failed, “SPEr” or “SEtE” will be displayed in the LCD window.

Sets the current process value for Upper Range Value (20 mA). Put appropriate pressure on Zero for 10 seconds and push the Span button for 5 seconds. This will display as “SPAn” in the LCD window. After checking this message, remove the finger from the button. Press the button for 3 seconds with 1-second intervals. This will display “-SP-“ in the LCD window. When this message is displayed, all Zero configurations have completed. If the process has failed, “SPEr” or “SEtE” will be displayed in the LCD window.
a. “SPEr”: Setting Value is over Sensor Limit Range or Less Minimum SPAN b. “SEtE”: Setting Value is not written on memory c. “ZtEr”: Setting Zero Trim value is 10% over Sensor Max Span d. “bEr1”: Zero/Span and Zero Trim functions are stopped in the middle of work
(button is pressed only one time or pressed continuously. This message is present for Button Error)
5.7 Configuration of Zero Point Adjustment
Zero Point Adjustment means to configure PV value which output after Zero Trim. Zero Point Adjustment is to configure a current PV Value for another value (which is not zero) by configuring the offset value of zero point. This is for configuring a current displayed value for a desired process value without making the process value zero. Especially, in case the of configuring level value, it is very difficult to make Sensor Zero Trim, this adjustment is a very convenient way to configure a current value for a desired value.
There are two ways to achieve Zero Point Adjustment of the Tek-Temp 2100A
A. Using the Zero/Span button on the transmitter B. Using HART communicator, HHT, etc.
The guide below shows a Zero Point Adjustment procedure using Zero/Span button:
x Loosen both bolts of the nameplate on the upside of the transmitter and push the right
end of nameplate back a little bit
x Apply necessary pressure and push Zero and Span button simultaneously for 3 seconds.
This will display “Z-tr” in LCD window. Continuously push the Zero and Span buttons for 3 seconds again. This will display “Z-AD” in LCD window. After checking this message, it should show that 0.01% diminishes whenever the Zero button is pushed, and 0.01% increases whenever the Span button is pushed. Pushing the button continuously changes the speed to fast or slow. If you push the Zero/Span button for 3 seconds or do not push any button for 30 seconds. “-Zo-“ message is displayed in the LCD window. When this message is displayed, all procedures has completed. The range for Zero Point Adjustment is permitted within 100% of Calibrated Span.
x Close the cover of nameplate and lock both bolts.

5.8 Shop Commissioning using HHT
Commissioning consists of testing the transmitter, testing the loop, and verifying the transmitter configuration data. The Tek-Temp 2100A Temperature Transmitter may be commissioned using HHT of HART supported either before or after installation.
If you connect a "TEST" pin, it's not communicated. If it doesn't expose electronics circuits after install, you must connect all jumpers to the transmitter in the shop commissioning level. Analog output of the transmitter is 4 - 20 mA, so it requires power supply at
11.9VDC - 45VDC and an Ampere meter for measuring output current. You must connect a 250 - 550ohm resistor in a power loop for HART Communication and HHT or PC Configurator.

5.11.1 Configuration of Current to Passive Mode
In the case of a short current loop, you must configure the current loop to passive mode to send or request data to change the transmitter. Don't believe the message indicating HHT; you must configure the Current Loop to passive mode with another operation.
5.11.2 Configuring Data Review
In cases of installing the transmitter in a factory site, before operating the transmitter re-examine and certify whether the configuration data corresponds with the factory application environment.
5.11.3 Check Output
Before others handle the transmitter, you must examine and confirm whether the transmitter operates properly and can suitably configure process variables.
x Process Variable
We use two progress variables in Tek-Temp 2100A Explosion-proof Temperature Transmitter. The pressure value is the Primary Variable and temperature value of pressure value configure SV (Secondary Variable) with fixed value. Moreover, this PV value outputs with 4 to 20mA analog value.
5.11.4 Basic Setup
You must configure the correlation variable for operating the current transmitter.
x Select Sensor Range
The temperature range to measure is dependent on the range code of the sensor. This value is automatically classified from the Temperature sensor module.
x Set Output Units
Select from the following engineering units: Unit: °C, °F, °R, °K, etc.

x Set Fail Mode
x Set Damping Time
Set the Zero and Span of 4 - 20mA analog output.
When the sensor is wrong or the microprocessor of the transmitter doesn't operate normally in order to output the current value of High or Low.
The sensor input value changes the response time of the transmitter into smooth variations of output readings caused by rapid changes in input. Determine the appropriate damping setting based on the necessary response time, signal stability, and other requirements of the loop dynamics of your system. The default damping value is 1.0 seconds, and can be reset to damping values between 0 - 60 seconds.
5.11.6 Configuration of Information Variable
x Set Tag
Tag Variable is an easy method to classify the transmitter in a multi-transmitter installation environment. Tag Character can be used; up to 8 words/numbers in of English.
x Set Messages
When use several transmitters, user can define for classification each transmitter and use 32 words of English/number. This message is saved in EEPROM of transmitter.

5.11.7 Configuration of Breakdown Diagnostic Function
x Loop Test
The Loop Test verifies the output of the transmitter, the integrity of the loop, and the operations of any recorders or similar devices installed loop. Perform the following procedure for a loop test.
a. Connect a reference meter to the transmitter. b. Select the Loop Test of HHT and operate the Loop Test. c. Select output current (4mA/20mA/etc.)
d. If the readings match, then the transmitter and the loop are configured and
functioning properly.
If the readings do not match, then you may have the current meter attached to the wrong loop, there may be a fault in the wiring, the transmitter may require an output trim, or the electrical current meter may be malfunctioning.
5.11.8 Calibration
A scaled system is implemented by calibrating the transmitter. Trim functions have several functions for the calibration. Explosion-proof Transmitters operate differently than analog transmitters. A Smart Transmitter uses a microprocessor that contains information about the sensor's specific characteristics in response to pressure and temperature inputs for calculating the Process Variable. The trim and re-range functions also differ. Re-ranging sets the transmitter analog output to the selected upper and lower range points and can be done with or without applied pressure. Reranging does not change the factory characterization curve stored in the microprocessor. Sensor trimming requires an accurate pressure input and adds additional compensation; this adjusts the position of the factory characterization curve to optimize transmitter performance over a specific pressure range. Re-range functions provide the ability to re­adjust the 4 to 20mA points sensor inputs.

6.2 Hardware Maintenance
Tek-Temp 2100A Explosion-proof Transmitters have no moving parts and require a minimum of scheduled maintenance. Both transmitters feature modular design for easy maintenance. If you suspect a malfunction, check for an external cause before performing the diagnostics as discussed later in this section.
6.2.1 Test Terminals
The test terminal is marked as TEST on the terminal block. The test and negative terminals are connected to the test terminals; so long as the voltage across the receptacles is kept below the diode threshold voltage, no current passes through the diode. To ensure that there is no leakage current through the diode while making a test reading, or while an indicating meter is connected, the resistance of the test connection or meter should not exceed 10 ohms. A resistance value of 30 ohms will cause an error of approximately 10 % of reading.
