Signet 8350-1 User manual

CAUTION!
• Remove power to unit before wiring input and output connections.
• Follow instructions carefully to avoid personal injury.
Signet 8350-1 Temperature Transmitter
2. 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.

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. The cutout must be
92 mm x 92 mm. Recommended clearance on all sides between instruments is 25 mm/1 in.
2. Slide the instrument into the cutout from the front of the panel.
3. Slide the 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.

Installation Detail
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.
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.

• During normal operation, ProcessPro displays the VIEW menu.
• When editing CALIBRATE or OPTIONS menus, ProcessPro returns to the VIEW menu if no activity occurs for
10 minutes.
• To select a VIEW display, press the ▲or ▼keys. The selections 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.
• Proportional Pulsing
The Open Collector output will generate a 100 mS pulse at the
rate defined by settings in the CALIBRATE menu (see page 6).
In the example below:
• 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.
The starting point, endpoint and maximum pulse rate are
selectable in the menu.

3.3 Open Collector Output
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. The output can be disabled when not in use.
• 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.

Check Sensor?
• Sensor not wired properly.
• Sensor connected to 8350 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 Temperature
field is greater than 20 °C (36 °F)
deviation from sensor input. (The 8350
allows a maximum of 20 °C offset.).
• Confirm calibration values.
• Replace defective sensor.

• Hysteresis value too large.
• Defective transmitter.
• Change the hysteresis value
• Replace transmitter
Value must be
