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 3-8052 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 ﬁeld installation options are included with the 3-8052 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.

3. Electrical Connections

Caution: Failure to fully open terminal jaws 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 jaws.

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

The terminals will accomodate conductors from 14 to 22 AWG.

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.

• The cable length from the sensor to the transmitter must not exceed 400 ft. (122 m)

• For best performance, ground the sensor SHIELD wire to a local earth ground at a point near the sensor.

(Experiment with connecting the sensor shield wire to different local ground points to identify best signal quality.)

• 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 keycode is necessary to change display selection.

• Output settings cannot be edited from the VIEW menu.

3.3 Relay Output

The relay output can be used as a switch that responds when the

process value moves above or below a setpoint.

• Low:

Output energizes when process variable is less than the setpoint.

The output will be de-energized when the process variable moves

above the setpoint plus the hysteresis value.

• High:

Output energizes when process variable is greater than the

setpoint. The output will be de-energized when the process

variable moves below the setpoint plus the hysteresis value.

• Off

The relays may be disabled if not being used.

Display Condition Possible Causes Suggested Solutions

Check Sensor?

• Sensor not wired properly.

• Sensor connected to 8450 while

power is on.

• Defective sensor.

• Correct sensor wiring.

• Recycle power with all sensors connected.

• Replace defective sensor.

Too much error

CHECK SENSOR

The value entered in Set Pressure ﬁeld is

greater than 5 psi deviation from sensor

input. (The 8450 allows a maximum of

5 psi calibration offset.).

• Conﬁrm calibration values.

• Remove sensor from installation, check

8450 reading (should be zero). If necessary,

Set Pressure to zero, reinstall sensor, then

recalibrate.

Reset to Factory

Calibration Value in SET PRESSURE ﬁeld is -999. Entering "-999" in this ﬁeld will remove all user

calibration input and restore the factory values.

Relay is always activated • Hysteresis value too large

• Defective transmitter

• Change the hysteresis value

• Replace transmitter

SETUP READ ERROR

Press Any Key Memory fault occurred.

• Press any key to reload factory presets.

• Reprogram all setpoints.

• If this message appears again, replace the

8450.
