Digi-Sense® TC9100 Advanced PID and On/Off Temperature Controller Quick-Start Guide

Models 89800-11 and 89800-12

Controller Description — Front Panel

The Digi-Sense TC9100 features a user-friendly interface with several buttons and indicators:

1. RUN/STOP Button: Starts or stops the temperature control process. When running, "Heat" and "Cool" indicators illuminate.
2. TUNE Button: Initiates the AUTO TUNE cycle. Auto tuning must be enabled in the setup mode for this function.
3. ALARM Button: Silences audible alarms and clears on-screen messages. It can either stop the process (ERROR) or not (WARNING) depending on the alarm type.
4. SELECT Button: Cycles through user-configurable set points, which are indicated by an underline. Use UP/DOWN arrows to change the selected set point.
5. MENU Button: Provides access to user-configurable setup parameters. Pressing once scrolls through options; holding it exits to the home screen, saving changes.
6. UP, DOWN, BACK Buttons: UP/DOWN arrows adjust set point values or numerical entries with an acceleration factor. Holding them increases/decreases text entries without acceleration. BACK moves through menus. Holding MENU exits to the main screen.
7. HEAT, COOL, AND TUNE Indicators: These indicators illuminate to show when the controller is actively in Heat, Cool, or Tune mode.

Acceleration Factor Table:

Numbers...	Increase/Decrease by...
0.0 - 0.9	0.1
0 - 9	1
10 - 100	10
100 +	50

Rear Panel Connections

The rear panel of the TC9100 includes the following connections:

1. IEC power cord connection: For connecting the power cord. (Refer to User Manual page 32 for additional cords).
2. Fuse: A replaceable fuse.
3. Heater/Cooler output: Connection for the heater or cooler. (Refer to User Manual pages 33-34 for optional cord adapters).
4. Power switch: To turn the unit on or off.
5. Grid support bracket: For stability.
6. Thermocouple input: Accepts various thermocouple types (J, K, N, R, S, T, B, and E) with a mini-connector.

Power Input: The unit supports IEC 60320 C19, 230 VOLT and 5-15R, 115VAC connections.

Setup and Operation

Initial Setup

Install the controller in a safe operating area.
Plug the heater or cooler into the output connector on the back of the controller.
Connect the thermocouple sensor input connector to the back of the controller. A ferrite clip should be placed over the lead wire of the thermocouple sensor for optimal performance (See User Manual page 31 for reference).
Plug the supplied AC cord into the IEC power connector on the back of the controller.

Basic Operation Setup

Turn the power switch ON.
Follow the instructions on the "welcome" screen.
Press the SELECT key to read descriptions of each front panel key.
Press the MENU key to skip instructions and enter the main operation screen.
Press SELECT to make a user-editable field active (indicated by an underline).
Use the UP/DOWN arrow keys to adjust values in editable fields.
Access user-configurable setup by pressing the MENU key from the system status screen.
Use the MENU key to advance through menu settings.
The TC9100 is factory set for PID operation with a Type J thermocouple input sensor. For different control modes, refer to the User Manual.
Changed settings are retained in memory upon returning to the System Status screen.
Refer to the User Manual (pages 29-30) for screen flow charts of the control menu layout.

Auto Tune Operation Setup

Ensure your process is set up as per the initial setup instructions.
Verify that the Auto Tune feature is enabled in the menu settings.
From the main operation screen, set the desired Set Point temperature.
Press the TUNE button; the Tune and Heat indicators will illuminate.
The Set Point value is locked during the Tune process and cannot be altered until it is complete or aborted.
Stopping the Tune operation before completion will revert PID settings to factory defaults.
PID values are saved in nonvolatile memory.
