Declaration of Conformity according to FCC Part 15

This device complies with Part 15 of the FCC rules. Operation
is subject to the following two conditions:
(1) This device may not cause harmful interference, and,
(2) This device must accept any interference received, including
interference that may cause undesired operation.

China RoHS (Go to www.gfsignet.com for details)

2. Installation

• ProcessPro transmitters are available in two styles: panel mount and fi eld mount. The panel mount is supplied with the necessary
hardware to install the transmitter. This manual includes complete panel mounting instructions.

• Field mounting requires one of two separate mounting kits. The 3-8052 integral kit joins the sensor and instrument together into a
single package. The 3-8050 Universal kit enables the transmitter to be installed virtually anywhere.

• Detailed instructions for integral mounting or other fi eld installation options are included with the 3-8052 Integral kit or the 3-8050
Universal kit.

2.1 Panel Installation

1. The panel mount transmitter is designed for installation using a 1/4 DIN Punch. For manual panel

cutout, an adhesive template is provided as an installation guide. Recommended clearance on all sides
between instruments is 1 inch.

2. Place gasket on instrument, and install in panel.

3. Slide mounting bracket over back of instrument until quick-clips snap into latches on side of instrument.

4. To remove, secure instrument temporarily with tape from front or grip from rear of instrument. DO NOT

RELEASE.

Press quick-clips outward and remove.

Caution: Failure to fully open terminal jaws before removing wire may permanently damage instrument.

Wiring Procedure

1. Remove 13 mm - 16 mm (0.5 in. - 0.625 in.) of insulation from wire end.

2. Press the orange terminal lever downward with a small screwdriver to open terminal jaws.

3. Insert exposed (non-insulated) wire end in terminal hole until it bottoms out.

4. Release orange terminal lever to secure wire in place. Gently pull on each wire to ensure a good connection.

Wiring Removal Procedure

1. Press the orange terminal lever downward with a small screwdriver to open terminal jaws.

2. When fully open, remove wire from terminal.

Wiring Tips:

• Do not route sensor cable in conduit containing AC power wiring. Electrical noise may interfere with sensor signal.

• Routing sensor cable in grounded metal conduit will help prevent electrical noise and mechanical damage.

• Seal cable entry points to prevent moisture damage.

• Only one wire should be inserted into a terminal. Splice double wires outside the terminal.

• If your system uses a single sensor, it must be located within 122 m (400 ft.) of the transmitter.

• If your system uses two sensors, the total length of cable connected to the transmitter is limited to 122 m (400 ft.)

• The 3 conductors from a dual-sensor system can be tied together and then a single set of wires continued on to the transmitter.

• For best performance, ground the sensor SHIELD wire to a local earth ground at a point near the sensor.
(Experiment by connecting the sensor shield wire to different local ground points to identify best signal quality.)

Terminals 3-4: Primary Loop Power

12-24 VDC ±10% system power and current loop connections.
