The device has exceptional stability for use in critical building performance applications with the popular versatility of our original Series MS2 Magnesense ® II transmitter. The MSX Pro simplifies the ordering process to deliver the desired configuration, which reduces product setup time. Pressure ranges of Pa, mm w.c., and in w.c. are available per device. All pressure ranges can be configured in unidirectional or bidirectional modes providing a total of 32 ranges. The MSX Pro transmitter can provide a linear pressure output or a linear velocity output with the square root extraction from the transmitter. Additional parameters have been included to expand the square root capability to calculate flow. Dual voltage and milliamp output signals can be used to provide control and equipment output signal verification.INSTALLATION Surface Mounting:Mount the transmitter on a vertical surface. The pressure sensor measurement is unaffected by orientation, but it is recommended the unit be mounted with the connections facing down to prevent moisture from entering either the pressure ports or the electrical cable entry. Attach the mounting flange to a flat surface using #8 x 1/2˝ pan head sheet metal screws. Do not over tighten.Duct Mounting (Universal model required):Mount the transmitter away from fans, corners, heating and cooling coils and other equipment that will affect the measurement of the pressure.1. To mount the transmitter, drill a .562˝ (12.70 mm) diameter hole into the duct. 2. Screw duct probe into back of housing. Insert transmitter probe into the duct.3. Mark location of mounting holes on duct using mounting flange as template. Drill holes.4. Attach mounting flange to duct with #8 x 1/2˝ pan head sheet metal screws. Do not over tighten screws.5. Place the included cap on the exterior positive pressure port.The Universal model can also be used as a standard wall mount transmitter. In this mode, do not use the duct probe and plug the port on the backside of the transmitterwith the included plug.1-29/32[48.43]1-29/32[48.43]ELECTRICALThe MSX Pro transmitter utilizes a 2-wire 4-20 mA Current Output , or a 3-wire 0-5 V / 0-10 V Voltage Output . It is also capable of Simultaneous Current and Voltage Output . The power and signals interconnect via a removable European-style four conductor terminal block, or optionally, via the included tooless terminal block. 2-Wire 4-20 mA Current OutputThe connections to the transmitter are made through terminals VDC and COM on the terminal block as shown in Figure 1. The terminal block is removable and each of the terminals are labeled next to the terminal block on the circuit board. Polarity is indicated by VDC and COM. See Figure 1.The maximum receiver load resistance (RL) for a given power supply voltage (Vps) is defined by the formula: Shielded 2-wire cable is recommended for control loop wiring. Ground the shield at the power supply end only.The receiver may be connected to either the negative or positive side of the loop, whichever is most convenient. Should polarity of the transmitter or receiver be inadvertently reversed, the loop will not function properly but no damage will be done to the transmitter.The maximum length of connecting wire between the transmitter and the receiver is a function of wire size and receiver resistance. That portion of the total current loop resistance represented by the resistance of the connecting wires themselves should not exceed 10% of the receiver resistance. For extremely long runs (over 1,000 feet), it is desirable to select receivers with lower resistances in order to keep the size and cost of the connecting leads as low as possible. In installations where the connecting run is no more than 100 feet, you can use a connecting lead wire as small as No. 22 ga.Selection of using a DC or AC power supply is made via the terminal block. See Figure 2 for DC Wiring. See Figure 3 for AC Wiring.The terminal block is removable and each of the terminals are labeled next to the terminal block on the circuit board. Positive polarity is indicatedby VOUT. AC/DC selection is made via the terminal block. If the polarity of the transmitter is inadvertently reversed, the unit will not function properly, but no damage will be done to the transmitter.The minimum receiver load is 1 kΩ. The resistance due to the wire should be low compared to the receiver load resistance. While the voltage at the terminal block remains unchanged with a 10 mA current flow, resistive losses in the wiring do cause errors in the voltage delivered to the receiver. For a 1% accurate gage, the resistance of the wires should be less than 0.1% of the value of the receiver load resistance. This will keep the error caused by the current flow below 0.1%.The output across VOUT and COM will be either 0-5 V, 0-10 V depending on the DIP switch setting. See DIP Switch Settings Section for more information.DC POWER SUPPLY 10-36 VDCV A CV D CC O MV O U TCURRENT RECEIVER+--+DC POWER SUPPLY 17-36 VDCVOLTAGE RECEIVER-++-V A CV D CC O MV O U T AC POWER SUPPLY 21.6-33 VACVOLTAGE RECEIVERV A CV D CC O MV O U T -+DO NOT EXCEED SPECIFIED SUPPLY VOLTAGE RATINGS.

Pull the LCD directly away from the product to remove. Reinstall the LCD afterwiring is completed.Simultaneous Current and Voltage OutputThe terminal block is removable and each of the terminals is labeled underneath the terminal block on the circuit board. Positive polarity is indicated by VOUT. The VDC terminal and a DC power supply must be used for Simultaneous Current and Voltage Output. The voltage output and the power supply must have separate wire leads that are only joined at terminal 2 of the transmitter. Additional error may occur for the voltage output if a single wire is used or if the wires are joined at the power supply or receiver.For the current output, the maximum allowable loop resistance (wiring + receiver resistance) is dependent on the power supply. The maximum loop voltage drop must not reduce the transmitter voltage below 17 V. The maximum loop resistance (R MAX ) for a given power supply voltage (V PS ) can be calculated using the following equation:The equation uses 17.0 instead of 10.0 as seen in the equation earlier with Figure 1. This represents the minimum voltage supply which is higher on the simultaneous output configuration due to the requirements of the voltage outputs.Shielded 4-wire cable is recommended for control loop wiring. Ground the shield at the power supply end only. Should the polarity of the transmitter or receiver be inadvertently reversed, the unit will not function properly, but no damage will be done to the transmitter.For voltage outputs, the minimum receiver load is 1 kΩ. The resistance due to the wire should be low compared to the receiver load resistance. While the voltage at the terminal block remains unchanged with a 10 mA current flow, resistive losses in the wiring do cause errors in the voltage delivered to the receiver. For a 1% accurate gage, the resistance of the wires should be less than 0.1% of the value of the receiver load resistance. This will keep the error caused by the current flow below 0.1%.The output across VOUT and COM will be either 0-5 V or 0-10 V depending on the DIP switch setting. See DIP Switch Settings Section for more information.Power SupplyRefer to the following tables for the required supply rating.DIP SWITCH SETTINGSDIP switch settings are marked directly on the PCBA as shown in Figure 5.

DIP Switch 6 - Response Time SelectionDIP Switch 6 toggles to select the desired response time.• When the switch is in the OFF or down direction, the transmitter response time will be instantaneous.• When the switch is in the ON or up direction, the response time will be 3 seconds. DIP Switches 7 and 8 - Maximum Range Selection (Pressure)DIP switches 7 and 8 work as a pair to select the maximum range output of the transmitter. Use the tables below to navigate pressure range selection. Alternatively, if using the device for velocity and flow, proceed to the next section.DIP Switches 7 and 8 - Maximum Range Selection (Velocity/Flow)DIP switches 7 and 8 work as a pair to select the maximum range output of the transmitter. Use the tables below to navigate velocity and flow range selection. CALIBRATIONThe transmitter security feature must be unlocked before calibration is accessible. See Section Program Menu-Menu Access Security. There is a 3 second delay from the time the zero or span calibration buttons are released until the time that the change in calibration takes place. This delay is used to prevent stress related offsets on the lower ranges.Zero CalibrationThe zero calibration can be set by applying zero pressure to both of the pressure ports and pressing the zero button for 3 seconds. If the LCD display is present, the display will read ZERO and then sequence back to the home display.The span calibration function allows the pressure value to be adjusted so that the currently applied pressure is the maximum configured pressure. This will in turn set the maximum analog output at the set pressure. It is recommended that the ZERO function be applied before performing a span. Apply the maximum desired pressure to the device, press and hold span for 3 seconds. If the LCD display is present, SPAN is displayed. The span function will be processed 3 seconds after the span button is released.For a positive span, apply pressure to the positive “+” port.LCD DISPLAYThe LCD comes with a housing cover, which contains a window. The display plugs into the pins on top of the circuit board. The LCD is 180° rotatable so that it will read properly if the device must be mounted with the connections facing up.The following error messages will appear if an LCD is present and the device is an error state.PROGRAM MENUHome MenuDuring normal operation, the display will be in the Home Menu and will display the current measured pressure and the engineering units.Menu Access SecurityBy default, a PIN code is not required to enter the configuration menus. However, if access to the menus needs to be restricted, follow the steps below.1. While in the Home Menu, press and hold the Zero and Span buttons until “PIN” is displayed.2. Press and hold the Zero and Span buttons until the current PIN setting isdisplayed (default is 0000).3. Use the Zero button to increment the selected digit (denoted by the caron ) orpress the Span button to select the next digit to the right.4. Any value between 0001 and 9999 will result in the requirement to enter the PINeach time the menu is entered. The value 0000 will disable the PIN entryrequirement.5. Press and hold the Span button until the next menu is displayed. PIN security setup is now complete.MAINTENANCE/REPAIRUpon final installation of the Series MSX Pro, no routine maintenance is required. The Series MSX Pro is not field serviceable and should be returned if repair is needed.

Offset Calibration偏移误差校正 This function can be used to correct the zero-point deviation (offset) of the output signal in depressurized state (example: to 0 V/4mA at zero Pa). Disconnect the unit from the pressure by opening both hose nozzles or removing the hoses. Then press the "M" button for 5 s. Setting of Switching Output This function is used to set the switching output to "switched through" for a pressure you have defined. Apply the pressure or pressure differential at which the switching output is to be connected. Then press the "S" button for 5 s until the LED flashes quickly (= value is saved). The LED lights up as soon as the defined pressure is reached or exceeded.
