Introduction
The Digi-Sense TC9000 Advanced PID and On/Off Temperature Controller (Models 89800-01
and 89800-02) 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 TC9000 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 TC9000 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.

1. RUN/STOP Button
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
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, LEFT Arrow Buttons
The UP and DOWN arrow buttons will increase or decrease the value of the set point selected (underlined
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 LEFT arrow 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.
. Change the set point with the UP and DOWN arrow buttons.

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.

Setup and Operation
Initial Setup
Install controller in safe operating area.
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 31 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.
Depending on process operation, follow the directions to set up the controller for the proper
operation of your process:
- PID (Factory default) on pages 8-16
- ON/OFF on pages 17-24
All changed settings will be retained in memory when returning to the System Status screen.
Use the flow charts (see pages 29-30) 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.
Stopping the Tune operation prior to it finishing will cause the PID settings to be returned to
factory default values.
PID values will be saved in nonvolatile memory.

PID Control Mode Setup:
Screen # 4 - Selecting Alarm Setting
Use the UP/DOWN arrow keys to change between Auto Reset, Manual Reset, and Off.
Press MENU key to advance to next screen.
- If Auto or Manual is selected, the controller will advance to screen # 5.
- If selection is OFF, the controller will advance to screen # 9.
Screen # 5 - Selecting Alarm Mode
Use the UP/DOWN arrow keys to select alarm mode.
Selectable alarm modes:
- Process High: The alarm will be activated if the temperature rises above the
user set alarm value.
- Process Low: The alarm will be activated if the temperature goes below the
user set alarm value.
- Process High/Low: The alarm will be activated if the temperature goes above or
below the high and low temperature levels set by user.
- Deviation High: Alarm activation point that changes with the change of the process set
point. Example: The user sets deviation high alarm at 30°C and has a process set point of
100°C. If the temperature reaches 130°C, the alarm will be activated. The user changes
process set point to 60°C. If process temperature reaches 90°C, the alarm will be activated.
- Deviation Low: Alarm activation point that changes with the change of the process set point.
Example: The user sets the deviation low alarm 30°C and the process set point is 100°C.
If the process temperature is 70°C or less, the alarm will be activated. If the process set point
temperature is set at 70°C, then if the process temperature is 40°C or less it will activate
the alarm.
- Deviation High/Low: Same as Deviation High and Deviation Low alarms. It has the
capability of having an alarm activate when the set point temperature goes above or
below a set point temperature.
- Deviation Band: Allows the user to set the alarm to be activated within a specified
temperature range.
