1. Installation
ProcessPro transmitters are available in two styles: panel mount and field 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 3-8051 integral kit oins 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 field installation options are included with the 3-8051 Integral kit or the 3-8050
Universal kit.
1.1 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 aws before removing wire may permanently damage instrument.
Wiring Procedure
1. Remove 0.5 - 0.625 in. (13-16 mm) of insulation from wire end.
2. Press the orange terminal lever downward with a small screwdriver to open terminal aws.
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 aws.
2. When fully open, remove wire from terminal.

3.1 System Power/Loop Connections
3.2 Sensor Input Connections
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.

• During normal operation, the ProcessPro displays the VIEW menu.
• When using the CALIBRATE or OPTIONS menus, the ProcessPro will return to the VIEW menu if no activity
occurs for 10 minutes.
• To select the item you want displayed, press the UP or DOWN arrow keys. The items will scroll in a
continuous loop. Changing the display selection does not interrupt system operations.
• No key code is necessary to change display selection.
• Output settings cannot be edited from the VIEW menu.
The Open collector output can be used as a switch that responds
when the flow rate moves above or below a setpoint, or it can be
used to generate a pulse that is relative to the flow volume or to
the flow rate.
•Low
Output triggers when the flow rate is less than the setpoint.
The output will relax when the flow rate moves above the setpoint
plus the hysteresis value.
•High
Output triggers when the flow rate is greater than the setpoint.
The output will relax when the flow rate drops below the setpoint
plus the hysteresis value.
•Frequency
Output is a pulse stream that is based on the input flow sensor
signal. Set for 1 (input frequency = output frequency). Set for
even numbers (2, 4, 6, 8 . . . . 254 maximum) to scale output
frequency.
•Pulse
Output is a pulse based on the volume of fluid that passes the
sensor. Set any value from 0.0001 to 99999.
The output may be disabled (Off) if not used.
