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. SINGLE SENSOR system MUST use terminals 3-4.

Starting point

The Open Collector output can be used as a switch that responds when the process value moves above or below a setpoint, or it can be used to generate a pulsing signal with a rate proportional to the process value.

Delta Temperature (Differential Mode)

If two sensors are connected to the transmitter, the DELTA (Sensor 1 - Sensor 2) can be assigned to output. To enable differential mode, the selected output "Source" selection must be set to "DT".

• Low: Output energizes when process variable is less than the setpoint. The output de-energizes 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 de-energizes when the process variable moves below the setpoint plus the hysteresis value.

• Proportional Pulsing The Open Collector output will generate a 100 mS pulse at the rate deﬁ ned by settings in the CALIBRATE menu (see page 6)

In the example:

• The output will be 0 pulses/min. at temperatures less than 5º.

• The output will be 50 pulses/min. at 7.5º.

• The output will be 100 pulses/min. at temperatures above 10º.

Sensor 1 must be equal to ID 1. If it is not, go to the Calibrate menu and switch the sensor ID.

In the example below, Sensor 1 is measuring 80º while sensor 2 is measuring 20º. The delta is 60º ( Sensor 1 - Sensor 2 = 60º)

To track the delta temperature using a 4-20 mA output: Loop1 Source: DT Loop1 Range: 0-100 Loop1: = 13.60 mA

The starting point, endpoint and maximum pulse rate are select able in the menu.

Select the desired mode of operation for the Open Collector output. Options available are Off, Low, High or Pulse. The signal may be disabled (Off) if not used.

In Low or High Mode, the Open Collector output will be activated when the temperature reaches this value. Be sure to modify this setting if you change the Temperature Units.

The Open Collector output will be de-energized at Setpoint ± Hysteresis, depending on High or Low Setpoint selection.

If the output is in PULSE mode, set the start and end point of the range and also set the maximum pulse rate. (The maximum PULSE rate setting is 400 pulses per minute.)

The combined Output Range and Pulse rate settings shown here indicate: "Start pulsing when the process value is 25° and increase the pulse rate up to the maximum of 120 pulses per minute when the process value reaches 45°"
