• 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.

[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.

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:

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.

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.

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.

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).

Note: The controller will not respond if Time1 is set to 0.

• 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 Start/Stop key indicator light will flash slowly. The temperature of Channel 1 will be displayed until the operating temperature for

both channels is reached. The heat output indicator lights (G & H, just below the display) will light up when-

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 Start/Stop 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]).

The cooking time has been set. [`idle] will appear on the display.

Five Second Timeout

When using the up or down keys to change a value, if you do not press any key for 5 seconds, the controller will automatically be set to the last value on the display and return to [`idle].

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).

Note: The controller will not respond if Time1 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 Start/Stop key will light up (flashing or steady).

• 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. The heat output indicator light (G, just below the display) will light up whenever

the controller is calling for heat. When the channel is at operating temperature (set points minus the ready band)

[ready] will appear on the display and the Start/Stop key indicator light will flash rapidly. You are now ready to cook.

• 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 the menu when the preheat feature is active (when the [Ready] parameter in the [SetUp] function of the Configuration Mode is set to [```Yes]).

1. Set the menu as shown earlier.

2. With [`idle] or time of day on the display, press the Start/Stop key. If the preheat condition (temperatures >= set point 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.

Adjust a Menu While Cooking

You can adjust the temperature and time settings during the cooking and hold sequences by performing the actions shown under “Set the Menu” earlier in this section.

38 ■ Watlow MINIC HEF 2000 Application 23

Changes can be made to temperature and time only during the portion of the cooking sequence in which they are active. For example: a change to the first cooking temperature [tENP1] can be made only when the first cooking temperature is being run during the cooking sequence.

Temperature changes made while cooking are saved and become part of the permanent menu. Time changes are not saved and do not become part of the permanent menu.

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 Start/Stop for 2 seconds. Heat outputs will switch off. The heat output indicator light 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 Start/Stop 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.

Timer Output

If [Etype]] / [T`OUt]] in the Configuration Mode is set to [``yes], when time is counting down Event Output 2 is on. It is off during [Pause], [`Idle] or [Hold].

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 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.
