The Digi-Sense TC9100 Advanced PID and On/Off Temperature Controller (Models 89800-11
and 89800-12) is designed to regulate a user-defined output device at a set point temperature.
The microprocessor control uses a PID algorithm that provides precise heating/cooling tolerances
for demanding applications in the laboratory or industrial setting.
The TC9100 is a microprocessor-based, digital indicating, single-loop temperature controller.
It has a single output located on the back of the controller. It features an auto-tuning function that
allows automatic configuration of the PID parameters with minimum user configuration required.
The TC9100 has a single thermocouple input that accepts J, K, N, R, S, T, B, and E sensors.
The controller automatically sets the PID parameters through a "learning" sequence in the
auto tune mode. PID parameters include proportional band, reset/integral, and rate/derivative.
The user-friendly LED display is to aid in monitoring and setup of the controller. The controller
automatically stores all user-defined information in nonvolatile memory.
Unpacking
Check individual parts against the list of items below. If anything is missing or damaged,
please contact your instrument supplier immediately.
1. Temperature controller
2. Grid support bracket (attached to the back of the controller)
3. 6-ft (3-m) detachable IEC power cord. Model 89800-11 comes standard with
a US 120 VAC plug; Model 89800-12 comes standard with a US 220 VAC plug.
See page 32 for additional cords.
4. Electrical noise canceling ferrite clip (connects to sensor input; see page 31 for reference)
Pressing RUN/STOP once will start the control process if the temperature Controller is stopped, or stop the control process if the
temperature controller is running. If the controller is running, “Heat” and “Cool” on-screen indicators will illuminate appropriately
in the “Alarm/Action Display”.
2. TUNE Button
Pressing TUNE once will start the AUTO TUNE cycle. AUTO TUNING must be enabled in the setup mode for this key to function.
(See page 14, Screen 16)
3. ALARM Button
In an ALARM situation, the screen will display either “WARNING” or “ERROR” with the corresponding message. A “WARNING”
will not stop the control process. An “ERROR” will stop the control process.
A. MANUAL RESET mode: Pressing ALARM once will silence the audible alarm and clear the on-screen alarm message. If the alarm situation
is still present, the “Alarm/Action Display” will remain illuminated. The alarm and on-screen message will not clear automatically, even if the
system is no longer in an alarm situation.
B. AUTO RESET mode: Pressing ALARM once will silence the audible alarm and clear the on-screen alarm message. If the alarm situation
is still present, the “Alarm/Action Display” will remain illuminated. If the system leaves an alarm situation, the system will automatically silence
the alarm and clear the on-screen alarm message.

4. SELECT Button
Pressing SELECT once will cycle through user-configurable control set points. All user-configurable set points will be underlined
with a greyed out line. The selected set point will be underlined. Change the set point with the UP and DOWN arrow buttons.
5. MENU Button
The MENU button provides access to all user-configurable setup parameters of the controller. Pressing this key once will scroll
through parameter options. Pressing and holding this key will exit to the home screen, saving any changes made up to that point.
6. UP, DOWN, BACK Buttons
The UP and DOWN arrow buttons will increase or decrease the value of the set point selected (underlined). Pressing the UP or
DOWN arrow keys will increase or decrease numerical entries by the least significant digit. The rate of acceleration will increase as
shown in the table below, starting from the least significant digit. Pressing and holding the UP or DOWN arrow key will increase or
decrease text entries without an acceleration factor. The Back button moves backwards through the General and Advanced Setup
Menus. To exit to the main screen from either menu, press and hold the MENU button.
Numbers… Increase/Decrease by…
0.0 – 0.9 0.1
0 – 9 1
7. HEAT, COOL, AND TUNE Indicators
When any of these modes are active they will have a block indicator on the display showing they are active. Example: When the
controller is in the heat mode and it is applying power to the heater output there will be an indicator block on the display to show
the heater output is active.
Plug the heater or cooler (sold separately) into the output connector located on the back of the
controller.
Connect the thermocouple sensor to the thermocouple input connector located on the back of
the controller.
Place the ferrite clip over the lead wire of the thermocouple sensor. (See page 28 for reference
picture of installation of ferrite clip.)
Plug the supplied AC cord into the IEC power connector located on the back of the controller.
Basic Operation Setup
Turn power switch ON, located on the back of controller.
Follow the instructions on the “welcome” screen.
- Press SELECT key to read a brief description of each key on the front of controller.
- Press the MENU key to skip the instructions and enter the main operation screen.
Press the SELECT key to make a user-editable field active. A line will appear under the field
when the field is active for editing.
Use the UP/DOWN arrow keys to adjust the value that is active in a user-editable field.
Enter the user-configurable setup by pressing the MENU key from the system status screen.
Use the MENU key to advance through each menu setting.
Hold UP and press DOWN arrow keys to jump directly to Output Power adjustment screen.
Depending on process operation, follow the directions to set up the controller for the proper
operation of your process:
- PID (Factory default) on pages 8-15
- ON/OFF on pages 16-22
All changed settings will be retained in memory when returning to the System Status screen.
Use the flow charts (see pages 26-27) to have a visual of the controls menu layout.
Auto Tune Setup
Set up your process as noted in the initial setup.
Verify that the Auto Tune feature is enabled in the menu settings.
From the main operation screen, set the set point temperature.
Press the TUNE button and the indicators showing Heat and Tune will be illuminated on display.
The Set Point value can not be altered after the Tune process has started. The value is locked
until the Tune process is complete or aborted by the user.
Please note that the controller will tune at 90% of the set point. Don’t be alarmed if the controller
does not reach your entered set point in the tune mode.
Stopping the Tune operation prior to it finishing will cause the PID settings to be returned to
Use the UP/DOWN arrow keys to adjust value.
The user-defined value when the alarm will exit an
alarm condition. Example: User has a Process High alarm
programmed with a value of 150°C and has set the Alarm Hysteresis of 1°C. The alarm has
been activated after the temperature reached 160°C. When temperature reaches 149°C,
the alarm condition will not be active.

WARNING: Do not enter the calibration gateway unless
you have the proper calibration equipment to calibrate the sensor inputs associated with
this control. Changing calibration settings in the controller can cause errors in sensor
temperature readings and operation of the control. For instructions on how to use the
calibration functions, contact your instrument supplier.
With SKIP selected, press the MENU key to advance to screen # 11.
Screen # 11 - Global Sensor Offset Calibration
Use the UP/DOWN arrow keys to change the offset value.
The use of another temperature device is required to
determine the correct offset needed.
Adjusting this value is offsetting the sensor input temperature being displayed.
When complete, press MENU key to advance to screen # 12.
Screen # 12 - Over Temperature Stop
Use UP/DOWN arrow keys to change the value.
When sensor temperature goes above this value, the output
device will be turned off.
When complete, press MENU key to advance to screen # 13.
Screen # 13 - Loop Break Stop
Default value is ENABLED. Use UP/DOWN arrow keys to
change the value.
Loop Break Stop is a feature that will stop the process output
while the controller is in the run mode. If the controller senses there is no change in temperature
in a user set amount of time, the output will be turned off and error message will be displayed on
the screen along with an audible alarm.
Set to DISABLED if this function is not required.
When complete, press MENU key to advance to screen # 14.
Use UP/DOWN arrow keys to change the value.
Set for the process that is being performed: Heat or Cool
