Quick Start Installation The TA2 is calibrated and configured with the information supplied to MAGNETROL with the order. The instrument can be installed, wired, and place directly into operation. Probe Installation Insert the probe into the pipe or duct at the appropriate location.
4. Connect the 4-20 mA signal wiring to TB3. Make connec- tions to A-, A+ for an active output signal (power supplied by TA2) or P-, P+ for a passive signal using an external power supply. 5. Optional Pulse Output: connect signal wiring to TB4. Make connections to A-, A+ for an active output (power supplied by the TA2) or P-, P+ for a passive signal using an external power supply.
Model Number Serial Number Electrostatic Discharge (ESD) Handling Procedure MAGNETROL electronic instruments are manufactured to the highest quality standards. These instruments utilize electronic components which may be damaged by static electricity present in most work environments. The following steps are recommended to reduce the risk of component failure due to electrostatic discharge: 1.
Installation 2.3.1 Electronics The instrument is rated for use in Class I, Division 1 and Class I, Division 2 areas. The enclosure is also rated NEMA 4X. Remote electronics (optional) should be installed in an easy to access location within 500 feet (150 meters) of the sensor.
Page 8
For applications where it is desirable to install or remove the probe without having to shut down the process, The MAGNETROL Retractable Probe Assembly (RPA) can be utilized. See the TA2 Sales Brochure (MAGNETROL bulletin 54-140) for more information. WARNING To avoid potential damage or injury, never loosen a compression fitting while sensor is under pressure.
Wiring There are two connections in the electronics enclosure for ⁄ " NPT or M20 connections. These are generally used as one connection for input power and one for output signal. 2.4.1 Power and Signal Connection The instrument has separate wiring connections for AC (100 to 264 VAC) and DC (15 to 30 VDC).
2.4.2 Ground Connection The instrument must be grounded in accordance with Article 250 of the National Electric Code. 2.4.3 4-20 mA Output A 4-20 mA output (Analog Output 1) of the flow rate is DC INPUT LOOP1/HART PULSE/ INPUT ALARM OUTPUT available at terminal block TB3.
2.4.5 Remote Electronics Power/Loop Board in If the electronics are remote from the probe, a remote Electronics Housing board with terminal blocks is provided in the housing on the probe. For cable lengths up to 150 feet, the connection between the probe and electronics should be an 8-conductor shielded cable (Belden 8104).
Configuring the Transmitter The TA2 electronics are easy to set up and configure to the user’s specifications. When specified with the order, the configuration settings are programmed into the instrument at the factory. If not, or if the user wants to modify the configuration settings, follow these instructions for config- uring the instrument.
2.5.2 Operator Keypad The TA2 has a local user interface using a 2-line ¥ 16- character liquid crystal (LCD) and 4-push-button keypad. All measurement data and configuration information is shown in the LCD. The TA2 is configured via a “tree” type menu structure where it is easy to access branches of the tree to configure the various parameters.
2.5.2.3 Numeric Entry The Numeric Entry Mode is used to enter numeric values. This mode is accessed when the Enter Key is pressed on a menu item that requires entry of a numeric value. Data is entered at the cursor position: Push Button Keystroke Action Moves to the next digit (0,1,2,3…9).
This mode is most commonly used when entering a new local tag line into the TA2. The local tag as shipped from the factory is “MAGNETROL TA2” and can be changed to permits the user to identify the instrument with a the actual tag line of the instrument or the service.
2.5.3 Password A password protection system restricts access to portions of the menu which affect the unit’s operation and configura- tion. The default user password installed in the TA2 at the factory is 0 which effectively disables the user password feature.

The previous page shows the I/O configuration menu for setting up the 4-20 mA loop, the Totalizers, and the Damping. The basic TA2 has a single 4-20 mA loop referred to as AO1. Optionally the TA2 can be provided with a second 4-20 mA loop referred to as AO2 and a Transistor Output that can be configured to provide either a Pulse Output or an Alarm Output (see page 10 for speci- fications).

2.5.10 Transistor Output The optional transistor output can be configured to provide a pulse output proportional to the flow rate or an alarm indication where the output can serve as a low flow or a high flow alarm indication. When used as a pulse output a multiplier factor can be applied. A selection of maximum frequency ensures that the pulse output from the TA2 does not exceed the maximum allowable frequency of any external counter.
Configuration Parameter Explanation Selects the operation of the transistor output. Can be set up for Pulse Output, Output Function Alarm, or Disabled. Default is disabled. Permits selection of the units for the pulse output. Select SCF (Standard Cubic Feet), Pulse Output Units (Normal Cubic Meters), Nl (Normal Liters), lb (Pounds), or kg (Kilograms).

Each instrument is calibrated and configured by MAGNETROL for the type of gas, pipe size, flow area and flow rate. Calibration is performed in a NIST trace- able flow bench. The TA2 provides real-time temperature compensation which adjusts the flow measurement due to changing gas properties caused by process temperature changes.
Use of the PACTware ™ PC program is highly recommended and invaluable for troubleshooting and advanced configuration. A HART RS232 or USB model (purchased separately) is required. See MAGNETROL PACTware ™ bulletin 59-101. 54-631 THERMATEL Model TA2 Transmitter...
