2. Wire the controller.

3. Configure the controller.

4. Program the menus.

5. Set the controller security.

6. Set the Real-time Clock. For instructions on Steps 1, 2, 3, 4, 5 and 6, see the Hardware & Software Setup

Guide.

7. Design, manufacture and apply faceplate overlay for end-users. (For a suggested design to suit this application, see this section. For overlay dimensions and guidelines, see the Hardware & Software Setup Guide.)

8. Operate the controller. (See this application guide.)

Startup

Apply power to the griddle. [`iDle] will appear on the display. If the Real-time Clock option is installed and [SetUp] / [CLoc`] = [``YES] the pre-

sent time of day will appear on the display.

Preheat

If the [Ready] parameter under the [SetUp] function in the Configuration mode is set to [``yes], the controller will detect temperatures and preheat to operating temperature (above set point minus the ready band).

• Press the key for the menu you want to run. Each key selects a different menu. You can select from up to six menus that control temperature and cooking time. Only one menu may be run at a time.

Note: The controller will not respond if you select an invalid menu (one for which Time 1 is set to 0).

The menu you have chosen becomes the current menu for controller operation. Until the menu is completed or canceled, the indicator light above the menu key will light up (flashing or steady) to indicate the active menu.

• If the griddle is not at operating temperature, it will preheat. Meanwhile: The word [Pre-`] [`Heat] will appear on the display for a few moments. The menu key indicator light will flash slowly. The temperature of Channel 1 will be displayed until the operating temperature for

both channels is reached.

ever the controller is calling for heat. When both channels are at operating temperature (set points minus the ready band)

[ready] will appear on the display and the menu key indicator light will flash rapidly. You are now ready to cook with the active menu.

If the griddle is at operating temperature, the display goes directly to [Ready] without indicating preheat or temperature.

Run a Menu (with preheat feature)

This procedure describes how to run an active menu when the preheat feature is active (when the [Ready] parameter in the [SetUp] function of the Configuration Mode is set to [```yes]).

1. With [`idle] or time of day on the display, press the key for the menu you want to run.

If the preheat condition (temperatures >= set points minus the ready band) has not been met, the griddle will preheat until [ready] appears on the display.

If the griddle is at operating temperature [ready] will appear on the display.

2. With [ready] on the display, place the food on the bottom griddle, lower the top griddle, and press the active menu key (indicated by the rapidly flashing indicator light).

The menu key indicator light will light up. Time will count down on the display.

3. Depending on how the controller was configured at [Etype] / [sound] the following will happen when the menu cycle is finished:

With Sound set to 0: The controller automatically switches to [`idle], where the controller maintains the temperatures at set point and does not run time. [`idle] or current time of day will appear on the display. The menu key indicator light flashes slowly.

edge and silence the tone by pressing the active menu key, or it will automatically time out within 20 seconds and go into idle while the menu key indicator light flashes slowly.

If Sound is set to 4 or 5, [``end] will appear on the display and the menu key indicator light will flash rapidly. You must acknowledge the audible tone by pressing the active menu key. Once acknowledged, the audible tone is silenced and the controller goes into idle.The menu key indicator light will flash slowly.

4. Raise the top griddle and remove the food. The controller will continue to regulate at the last set point that was run. The menu

key indicator light will flash slowly.

5. To repeat cooking, repeat steps 1 through 4.

Run a Menu (without preheat feature)

This procedure describes how to run an active menu when the preheat feature is inactive (when the [Ready] parameter in the [SetUp] function of the Configuration Mode is set to [```no]).

1. With [`idle] or time of day on the display, place the food on the griddle.

2. Lower the top griddle and press they key for the menu you want to run.

The menu key indicator light will light up. Time will count down on the display.

3. Depending on how the controller was configured at [Etype] / [sound] the following will happen when the menu cycle is finished:

If Sound is set to 1, 2, or 3, [``end] appears on the display and an audible tone will be emitted. The menu key indicator light will flash rapidly. You can acknowledge and silence the tone by pressing the active menu key, or it will automatically time out within 20 seconds and go into idle while the menu key indicator light flashes slowly.

If [Sound] is set to 4 or 5, [``end] will appear on the display and the menu key indicator light will flash rapidly. You must acknowledge the audible tone by pressing the active menu key. Once acknowledged, the audible tone is silenced and the controller goes into idle.The menu key indicator light will flash slowly.

4. Raise the top griddle and remove the food.

8 ■ Watlow MINICHEF 2000 Application 20

The controller will continue to regulate at the last set point that was run. The menu key indicator light will flash slowly.

5. To repeat cooking, repeat steps 1 through 4.

Cancel a Menu

Canceling a menu stops controller operation completely. The controller does not maintain set point temperatures or run time. You cancel a menu to run another menu, stop menu operation for any reason, or are preparing to shut off the griddle.

• Press the active menu key for 2 seconds. Heat outputs will switch off. Heat output indicator lights will switch off. [`idle]

or the time of day will be on display.

Change Menus or Restart

1. If the controller is preheating or running a menu, cancel the menu by pressing and holding the active menu key for 2 seconds. If the controller is in [`idle] go to 2.

2. Press the key for the menu you want to run. Based on its programming, the unit will run the menu in one of the ways described

earlier.

Temperature Alarms

The controller will alert you to temperature alarm conditions if they occur. If an alarm occurs, take action as determined by your supervisor. See the Appendix in the Hardware & Software Setup Guide for a Troubleshooting Chart and a summary of temperature alarms.

Errors

The controller will alert you to errors if they occur. Errors are critical problems that shut down the unit. If an error occurs, an error message will appear on the display. You should switch off the power and call for service.

See the Appendix in the Hardware & Software Setup Guide for a Troubleshooting Chart and a summary of errors.
