DocumentDocumentTPE-1483-10 TPE-1483-20 TPE-1483-30 Differential Pressure Transmitter Installation Instructions INTRODUCTION The differential pressure transmitter is designed with dual remote sensors that enable it to accept high pressure in ranges up to 5 PSI to 500 PSI. All models can handle overload pressure 2X the maximum fully scale range and burst pressure is 5X the maximum full scale range. Features include field selectable pressure ranges and output signal types, output reversal and slow damping, port swapping and bidirectional measurements for the most flexible applications. The output signal is factory calibrated and temperature compensated for the highest start-up accuracy. WARNING : Ensure that the maximum individual port pressure does not exceed the highest pressure range of the unit. For example, the highest individual port pressure on a 02 Range Code is 100 PSI. Exceeding this may damage the sensors and give erroneous readings. See Figure 12 for ratings. BEFORE INSTALLATION Read these instructions carefully before installing and commissioning the dewpoint transmitter. Failure to follow these instructions may result in product damage. Do not use in an explosive or hazardous environment, with combustible or flammable gases, as a safety or emergency stop device or in any other application where failure of the product could result in personal injury. Take electrostatic discharge precautions MOUNTING during installation and do not exceed the device ratings. The transmitter mounts on a vertical surface using the two integrated mounting holes. The remote sensor cable connection should be located on the bottom of the enclosure. The two mounting holes will facilitate a #10 size screw (not supplied). See Figure 1. Ensure there is enough space around the unit to make the electrical Figure 1 connections and that it is within an acceptable distance for the length of remote sensor cables. Avoid locations with severe vibrations or excessive moisture. The enclosure has a standard opening for a conduit connector or cable gland type fitting. In this position the High port is on the left and the Low port is on the right as shown on the PCB. The enclosure has a hinged cover with a latch. Open the cover by pulling slightly on the latch on the bottom side of the enclosure and at the same time pulling on the cover, as illustrated in Figure 2. A 1/2" NPT threaded connection hole is provided in the left side of the enclosure as shown in Figure 3. Screw the EMT connector or cable gland connector in until tight. See Figure 4. It is recommended that weatherproof conduit or cable gland fittings be used. The F style enclosure includes 1/2" NPT to M16 thread adapter and cable gland fitting. Figure 2 Two security screws are provided which can be installed to help secure the cover once settings and wiring connections are complete. See Figure 4. Figure 3 Figure 4 Figure 5 Conduit Thread adapter and cable gland fitting I7N1-B7L--0D1P9X-X0X6-E03 EMT Connector Page 1 PLUMBING The two stainless steel pressure sensors are labeled High and Low. The output signal will indicate a positive value when the pressure applied to the High sensor is greater than the pressure applied to the Low sensor, so ensure the sensors are connected correctly as shown in a typical application in Figure 6. Both sensors incorporate 1/4" NPT male threads for connection to the pipe being monitored. Do not allow material to fall into the pressure ports as contamination could damage the sensors. It is recommended to use Teflon tape to prevent leaks. IMPORTANT: Before installing the sensor(s) ensure the sensor port, fitting or shutoff valve is free of any fluids in the area the sensor is being installed. Failure to remove excessive fluids may damage the sensor during pressurization. Remove the High pressure sensor from the remote cable by unscrewing and pulling apart from the remote cable boot as shown in Figure 7. Wrap 1/4" NPT male sensor threads with Teflon tape. Screw into the sensor port on the pipe being monitored until finger tight. Use an appropriate size wrench to tighten the sensor until snug as shown in Figure 8. Reconnect the remote sensor cable you aligning the remote sensor cable boot and screwing onto sensor. See Figure 9. Repeat for the Low pressure sensor.

I7N1-B7L--0D1P9X-X0X6-E03 Page 2 WIRING · Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or equipment damage. · Use 14-22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit with wiring used to supply inductive loads such as motors. Make all connections in accordance with national and local codes. · Pull at least six inches of wire into the enclosure, then complete the wiring connection according to the wiring diagram for the applicable power supply and output signal type. · Connect the plus DC or the AC voltage hot side to the PWR terminal. For voltage output or AC power, the supply Common is connected to the COM terminal. DO NOT connect power to the OUT terminals as the device will be damaged. It has half-wave power supply so the supply Common is the same as the signal Common. See Figure 11. · The analog output is available on the OUT terminal. Check the controller Analog Input to determine the proper connection before applying power. · If using the Zero function, connect the Remote Zero Switch between the ZERO and COM terminals.

Use <UP> or <DOWN> to change it to Reverse (20-4 mA, 5-0 Vdc or 10-0 Vdc. <MENU> Press to save and advance to next menu item 6. PRESSURE PORT P. Port Direct The Pressure Port defaults to Direct (HIGH Port = High Pressure, LOW Port = Low Pressure). Use <UP> or <DOWN> to change it to Reverse (HIGH Port = Low Pressure, LOW Port = High Pressure) if it is necessary to swap the ports due to a plumbing error. <MENU> Press to save and advance to next menu item 7. BACKLIGHT Backlite Auto The backlight operation defaults to Auto operation. It can be set to Off or On Auto using <UP> or <DOWN>. Auto means the LCD backlight only lights when a menu is accessed, off means it never lights and on means it is always on. <MENU> Press to exit and return to normal operation. OPERATION During normal mode the device reads the pressure sensors and calculates the pressure value depending on the selected range. The pressure value is displayed on the LCD and set as the output value for the analog output. The output value is updated once per second. For normal operation such as 0-100 PSI, the pressure applied to the High port must be higher than the pressure applied to the Low port. If the pressure connection is reversed then the transmitter will always output 4 mA. If the Low port is left open to ambient pressure, then the High port is used to measure a positive pressure and 0 PSI = 4 mA and 100 PSI = 20 mA. For bi-directional operation such as ±100 PSI, the pressure applied to the High port should be higher than the pressure applied to the Low port for a positive output response. Negative pressure is indicated if the High pressure is less than the Low pressure. In this case -100 PSI = 4 mA and +100 PSI = 20 mA. Since the transmitter is linear 0 PSI = 12 mA. The output value may be affected by device settings such as the pressure damping time. The pressure averaging setting controls how many readings are averaged to form the output value. For example, if the pressure averaging value is set to 30 seconds then 30 one-second readings are stored and averaged to form the output value. The next second will add a new reading and delete the first to form a new 30 second average for output. The output gets updated every second with a new average reading. The averaging value can be set from 1 to 60 seconds via the User Menu. During normal mode, the device also monitors the <ZERO / UP>, <DOWN> and <MENU> keys and takes appropriate action. The keys are used to access the User Menu. The device also monitors the Volt/mA jumper to determine the appropriate output scaling. The voltage span may be set via the User Menu to either 0-5 Vdc or 0-10 Vdc. NOTE: Both the low and high pressure sensors must be open to atmosphere to perform the autozeroing function. A sensor auto-zero can be initiated by pressing and holding the internal <ZERO> button for at least 3 seconds. If both pressure ports are close to zero pressure, then the device will calibrate with a new zero point. The auto-zero can also be initiated by holding the ZERO terminal low for 3 seconds. Generally, it is not recommended that a span calibration be performed in the field unless a high-quality calibrator with low differential pressure ranges is available and the temperature of the sensor can be maintained.
