Paragon Controls Incorporated 1 Revision Level 012 1. INTRODUCTION 1.1. DESCRIPTION The MicroTransEQ Signal Processor employs current state-of-the-art digital microprocessor technology to produce highly stable and accurate differential pressure and air flow measurements. The MicroTransEQ is factory configured and calibrated to the exact specification determined at time of order. Simple field configuration of engineering units, operating range, process noise filtering, alarm set points, etc., are performed via password protected intuitive menus that are accessed through the integral six button touch pad. Device monitoring and configuration can also be performed by a building management system through a LonWorks®, BACnet®-MS/TP Master, or Modbus® Slave communication network. Optional features include AutoZero; High/Low Remote Alarms; Temperature Compensation; and LonWorks®, BACnet®-MS/TP Master, and Modbus® Slave communication. 1.2. BASIC OPERATION The transducer receives a differential pressure signal from the pressure or flow sensing element. This signal is scaled and linearized before being displayed and transmitted out as a 4-20mA, 0-5VDC, or 0- 10VDC signal. The AutoZero option detects and corrects any zero offset caused by large ambient temperature changes. The Temperature Compensation option compensates the flow and velocity signal for density changes caused by variations in the process air temperature. An external temperature transmitter or input signal from the building management system is required. 1.3. SPECIFICATIONS 1.3.1. Power Supply 20 to 28 VAC/DC 1.3.2. Power Consumption Standard Unit: 216mA at 24VAC 150mA at 24VDC Full Options: 250mA at 24VAC 175mA at 24VDC 1.3.3. Accuracy ±0.25% full scale (Standard) ±0.10% full scale (Optional) 1.3.4.

Electrical Connections Before any electrical connections are made, ensure the POWER SWITCH is in the OFF position. 1.4.2. Static Electricity The circuit board contains components which are susceptible to damage caused by static electrical discharge. Should it be necessary to remove the circuit board from the enclosure, appropriate precautions must first be taken to ensure that the operator and the circuit board are at the same electrical potential.

FIELD SETUP MENUS To set parameters under the Field Setup Menus refer to the following procedure, below subsections, and Section 6.3 for Key functions. Step 1. Enter the Field Setup Menu by depressing and holding the Enter Key for 5 seconds. Step 2. Once in the Field Setup Menu, use the Up/Down Keys to highlight the required parameter for configuration as shown in Sections 8.1 through 8.12. Press the Enter Key once to access the highlighted parameter Menu. Step 3. Once in the parameter menu, the parameter can be changed using Up/Down/Left/Right Keys. After the parameter has been changed, press the Enter Key once. Then Press the ESC Key once to return to the Field Setup Menu. Step 4. After all of the required parameters have been configured, exit the Field Setup Menu by pressing the ESC Key. The Process Display (see Section 6.2) will then be displayed. 8.1. OPERATING RANGE The Operating Range allows the user to enter a value which will represent 100% of the process output signal (5VDC, 10VDC, or 20mA). The menu will display the Maximum Full Scale Value possible for the user to enter as the Operating Range.

Paragon Controls Incorporated 20 Revision Level 012 -FLOW CORRECTION EXAMPLE- The balancer is consistently measuring a value of 9,500 CFM, which is 500 CFM less than the 10,000 CFM value on the MicroTransEQ display. The user would then perform the following math function: Measured Value / Displayed Value = K-Factor so 9,500 CFM / 10,000 CFM = 0.950. The user would enter 0.950 for the K-Factor Flow Correction. If the K-Factor Calculator is used, the K- Factor Flow Correction would automatically update the K Factor. 8.6.
