Startup

Apply power to the fryer and add cooking oil if necessary.

Initial Preheat

At power-up, the unit will preheat to the temperature value set in the Configuration Mode [Etype] / [preHt]. The display will show [prE-`] [`Heat] followed by oil temperature as the oil heats up.

When the unit reaches initial preheat temperature, [ready] will flash once on the display and an audible tone will sound for 2 seconds. Then [`idle] will appear on the display. If the Real-time Clock option is installed and [SEtUp] / [Cloc`] is set to [``yes], the time of day will appear on the display.

If the preheat condition is met before power-up, the controller goes directly to idle, and does not display [rEAdy] or sound an audible tone.

Preheat

If in the Configuration Mode [SEtUP] / [ready] has been set to yes, the controller will detect temperatures and preheat to operating temperature (above relative set point minus the ready band) as required.

• Activate the menu by pressing the Start/Stop key.

If the fryer is not at operating temperature, it will preheat. Meanwhile: The word [Pre-`] [`Heat] will appear on the display for a few moments. The

the controller is calling for heat. When the fryer is at operating temperature (above relative set point 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 fryer is at operating temperature, the display goes directly to [ready] without indicating preheat or temperature.

The Melt Cycle

To avoid burning congealed oil (shortening), a slow heating action may be necessary. If this is desired, be sure that in the Configuration Mode [etype] / [melt] has been set to [```on]. Then, when the oil temperature is below 212 °F the heat output will be limited to 10% of full power. This reduces the chance of burning congealed oil while it is heating.

Run a Menu (with preheat feature)

This procedure describes how to run an active menu when the preheat feature is inactive — in other words, when the [ready] parameter in the [setUp] function of the Configuration Mode is set to [``yes].

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

If the selected menu’s preheat condition (setpoint minus the ready band) has not been met, the fryer will preheat until [Ready] appears on the display. If the fryer is at operating temperature [Ready] will immediately appear on the display.

2. With [Ready] on the display, place the food in the basket and press the action menu key (indicated by the flashing red light.) The menu key indicator light will light up, the basket will lower automatically. Time will count down on the display.

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 time of day will appear on the display. The menu key indicator light will flash slowly.

With Sound set to 1, 2, or 3, [``End] will appear 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 time out in 1 to 20 seconds and go into idle. The menu key indicator light will flash slowly.

With Sound 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 tone is silenced and the controller goes into idle. The menu key indicator light will flash slowly.

5 Remove the food from the basket. The controller will continue to regulate to the last

set point. The menu key indicator light will flash slowly.

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

Run a Menu (without preheat feature)

This procedure describes how to run a menu when the preheat function is inactive — that is, when the [Ready] parameter in the [SetUp] function of the Configuration Mode is set to [```no] — and initial preheat power-up has been completed.

1. With [`idle] on the display, place the food in the basket.

2. Press the key for the menu you want to run. The menu key will light up, the basket will lower automatically, and then time will count down on the display.:

3. If programmed, as the time counts down, a mid-menu alarm message [M`__] / [ALArn] will appear on the display.

Startup

1. Apply power to the fryer and add cooking oil if necessary.

Initial Preheat

At power-up, the unit will preheat to the temperature value set in the Configuration Mode [Etype] / [preHt]. The display will show [Pre-`] [`HEat] followed by oil temperature as the oil heats.

When the unit reaches initial preheat temperature, [Ready] will flash once on the display and an audible tone will sound for 2 seconds. Then [`idle] will appear on the display. (If Real Time Clock option is installed and [setUp] / [Cloc`] is set to [``yes], the time of day will appear on the display).

Preheat

If in the Configuration Mode [SEtUP] / [ready] has been set to yes, the controller will detect temperatures and preheat to operating temperature (above relative set point minus the ready band) as required.

• Activate the menu by pressing the Start/Stop key.

If the fryer 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 is reached.

the controller is calling for heat. When the fryer is at operating temperature (above relative set point 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 fryer is at operating temperature, the display goes directly to [ready] without indicating preheat or temperature.

The Melt Cycle

To avoid burning congealed oil (shortening), a slow heating action may be necessary. If this is desired be sure that in the Configuration Mode [etype] / [melt]has been set to [```on]. Then, when the oil temperature is below 212ºF the heat output will be limited to 10% of full power. This reduces the chance of burning congealed oil while it is melting.

Run a Menu (with preheat feature)

This procedure describes how to run an active menu when the preheat feature is inactive — in other words, when the [ready] parameter in the [setUp] function of the Configuration Mode is set to [``yes]

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

If the selected menu’s preheat condition has not been met, the fryer will preheat until [ready] appears on the display. If the fryer is at operating temperature, [ready] will immediately appear on the display.

2. With [ready] on the display, place the food in the pressure fryer and secure the lid on the pressure vessel.

3. 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. When the menu cycle nears completion, pressure will be released from the fryer

based on the time programmed in Configuration Mode, [etype] / [Ptine]

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.

With Sound set to 1, 2, or 3, [``end] will appear 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 time out in 1 to 20 seconds and go into idle. The menu key indicator light will flash slowly.

With Sound 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 tone is silenced and the controller goes into idle. The menu key indicator light will flash slowly.

5. After pressure release time is complete, open lid and carefully and safely remove the food. The controller will continue to regulate at the last setpoint. The menu key indicator light will flash slowly.

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

Run A Menu (without preheat feature)

This procedure describes how to run a menu when the preheat function is inactive — in other words, when the [Ready] parameter in the [SetUp]function of the Configuration Mode is set to [```no] — and initial preheat power-up has been completed.

1. With [`idle] on the display, place the food in the pressure fryer and secure the lid on the pressure vessel.

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

2. Press the key for the menu you want to run. The indicator above the selected menu key will light up. Time will countdown on the

display. When the menu cycle nears completion, pressure will be released from the fryer

based on the time programmed in Configuration Mode [etype] /[Ptine].

3. When the cooking cycle is finished, one of the following will happen, depending on the way the controller was programmed at [etype] / [sound]:

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

5. To repeat cooking, repeat steps 1 through 3.

Event outputs

Event output 1 assists in controlling pressure. Event output 1 will switch on when a menu starts and switch off when the time remain-

ing is equal to the value programmed in Configuration Mode under [Etype] / [PtinE].

If a menu is cancelled, Event output 1 switches off immediately.

Cancel a menu

Canceling a menu stops controller operation completely. The controller does not maintain set point temperatures or run time. Users may cancel a menu in order to run another one, to stop menu operation for any reason, or when preparing to shut off the fryer.

Press the active menu key for 2 seconds. Heat outputs will switch off. Heat output indicator lights will switch off. The display

With Sound 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 tone is silenced and the controller goes into [`idle]. The menu key indicator light will flash slowly.

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

Change menus or restart

With the controller in idle, close pressure vessel or ensure pressure vessel is closed. Press the key for the menu you want to run.

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.

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].

Initial Preheat

At power-up, the unit will preheat to the temperature value set in the Configuration Mode [seTUp] / [Ready]. The display will show [prE-`] [`Heat] followed by oil temperature as the oil heats up.

When the unit reaches initial preheat temperature, [ready] will flash once on the display and an audible tone will sound for 2 seconds. Then [`idle] will appear on the display. If the Real-time Clock option is installed and [SEtUp] / [Cloc`] is set to [``yes], the time of day will appear on the display.

If the preheat condition is met at power-up, the controller goes directly to idle, and does not display [rEAdy] or sound an audible tone.

Preheat

If in the Configuration Mode [SEtUP] / [ready] has been set to yes, the controller will detect temperatures and preheat to operating temperature (above relative set point minus the ready band) as required.

• Activate the current menu by pressing the Start/Stop key.

If the fryer 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 is reached.

The heat output indicator light - G, just below the display- will light up whenever the controller is calling for heat.

When the fryer is at operating temperature (above relative set point 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 fryer is at operating temperature, the display goes directly to [ready] without indicating preheat or temperature.

To avoid burning congealed oil (shortening), a slow heating action may be necessary. If this is desired, be sure that in the Configuration Mode [etype] / [melt] has been set to [```on. Then, when the oil temperature is below 212ºF the heat output will be limited to 10% of full power. This reduces the chance of burning congealed oil while it is heating.

Run a Menu (with preheat feature)

This procedure describes how to run an active menu when the preheat feature is active — in other words, 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 menu’s preheat condition has not been met, the fryer will preheat until [ready] appears on the display. If the fryer is at operating temperature, [ready] will immediately appear on the display.

2. With [ready] on the display, place the food in the pressure fryer and secure the lid on the pressure vessel.

3. Press the Start/Stop key (indicated by the rapidly flashing indicator light). The Start/Stop indicator light will light up. Time will count down on the display. When the menu cycle nears completion, pressure will be released from the fryer

based on the time programmed in Configuration Mode, [etype] / [Ptine].

4. When the cooking cycle is finished, the controller goes into idle and the Start/Stop key indicator light and heat output will switch off.

5. After pressure release time is complete, open lid and carefully and safely remove the food. The controller will continue to regulate at the last setpoint. The menu key indicator light will flash slowly.

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

This procedure describes how to run a menu when the preheat function is inactive — in other words, when the [Ready] parameter in the [SetUp]function of the Configuration Mode is set to [```no] — and initial preheat power-up has been completed.

1. With [`idle] on the display, place the food in the pressure fryer and secure the lid on the pressure vessel.

2. Press the Start/Stop key. The Start/Stop indicator light will light up. Time will count down on the display. When the menu cycle nears completion, pressure will be released from the fryer

based on the time programmed in Configuration Mode [etype] / [Ptine].

3. When the cooking cycle is finished, the controller goes into idle and the Start/Stop key indicator light will switch off. The controller will continue to regulate the set point temperature.

4. Remove the food carefully and safely.

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

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.

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.

Event outputs

Event output 1 assists in controlling pressure. Event output 1 will switch on when a menu starts and switch off when the time remain-

ing is equal to the value programmed in the Configuration Mode under [Etype] / [PtinE].

If a menu is cancelled, Event output 1 switches off immediately.

Application 15 Watlow MiniChef 2000 ■ 63

Cancel a menu

Canceling the menu stops controller operation completely. The controller does not maintain set point temperatures or run time. Users may cancel the menu in order to run another one, to stop menu operation for any reason, or when preparing to shut off the fryer.

Press the Start/Stop for 2 seconds. Heat outputs will switch off. Heat output indicator lights will switch off. The display

presents [`idle] or the time of day will appear on the display.

Change menus or restart

Startup

Apply power to the fryer and add cooking oil if necessary.

Initial Preheat

At power-up, the unit will preheat to the temperature value set in the Configuration Mode [Etype] / [preHt]. The display will show [prE-`] [`Heat] followed by oil temperature as the oil heats up.

When the unit reaches initial preheat temperature, [ready] will flash once on the display and an audible tone will sound for 2 seconds. Then [`idle] will appear on the display. If the Real-time Clock option is installed and [SEtUp] / [Cloc`] is set to [``yes], the time of day will appear on the display.

If the preheat condition is met before power-up, the controller goes directly to idle, and does not display [rEAdy] or sound an audible tone.

Preheat

If in the Configuration Mode [SEtUP] / [ready] has been set to yes, the controller will detect temperatures and preheat to operating temperature (above relative set point minus the ready band) as required.

• Activate the menu by pressing the menu key.

If the fryer is not at operating temperature, it will preheat. Meanwhile:

The heat output indicator light - G, just below the display- will light up whenever the controller is calling for heat.

When the fryer is at operating temperature (above relative set point 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 fryer is at operating temperature, the display goes directly to [ready] without indicating preheat or temperature.

The Melt Cycle

To avoid burning congealed oil (shortening), a slow heating action may be necessary. If this is desired, be sure that in the Configuration Mode [etype] / [melt] has been set to [```on]. Then, when the oil temperature is below 212 ºF the heat output will be limited to 10% of full power. This reduces the chance of burning congealed oil while it is heating.

Run a Menu (with preheat feature)

This procedure describes how to run an active menu when the preheat feature is active — in other words, when the [ready] parameter in the [setUp] function of the Configuration Mode is set to [``yes].

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

If the selected menu’s preheat condition has not been met, the fryer will preheat until [Ready] appears on the display. If the fryer is at operating temperature [Ready] will immediately appear on the display.

2. With [Ready] on the display, place the food in the fryer and press the action menu key (indicated be the flashing red light.) The menu key indicator light will light up. Time will count down on the display.

Start-up

Apply power to the fryer and add cooking oil if necessary.

Select a Menu

1. Press the Menu Select key. The controller will display the currently selected menu. If no menus have been pro-

grammed the word [`none] will appear on the display.

2. Press the Up-arrow or Down-arrow key until the menu you want appears on the display.

The controller will only display valid menus (those for which Time1 for the menu is set to greater than 0).

3. Press the Menu Select key again. The menu you have chosen becomes the current menu for controller operation.

Initial Preheat

At power-up, the unit will preheat to the temperature value set in the Configuration Mode [Etype] / [preHt]. The display will show [Pre-`] [`HEat] followed by oil temperature as the oil heats.

When the unit reaches initial preheat temperature, [Ready] will flash once on the dis-

play and an audible tone will sound for 2 seconds. Then [`idle] will appear on the display. If Real Time Clock option is installed and [setUp] / [Cloc`] is set to [``yes], the time of day will appear on the display.

If in the Configuration Mode [SEtUP] / [ready]] has been set to yes, the controller will detect temperatures and preheat to operating temperature (above relative set point minus the ready band) as required.

• Activate the menu by pressing the Start/Stop key.

If the fryer 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 is reached.

The heat output indicator light – G, just below the display – will light up whenever the controller is calling for heat.

When the fryer is at operating temperature (above relative set point 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 fryer is at operating temperature, the display goes directly to [ready] without indicating preheat or temperature.

The Melt Cycle

To avoid burning, congealed oil requires a slow heating action. If in the Configuration Mode, [etype] / [melt] has been set to on, when the oil temperature is below 212°F the heat output will be limited to 10% of full power.

Run a Menu (with preheat feature)

This procedure describes how to run an active menu when the preheat feature is active — in other words, when the [ready] parameter in the [SetUp] function of the Configuration Mode is set to [yes``].

1. Select the menu you want to run as shown earlier in “Select a Menu”.

2. With [`idle] or time of day on the display, press the Start/Stop key.

Auxiliary Idle Set Points

In some cases you may want to control at some non-cooking temperature such as during cleaning, preheating or to preserve the life of the oil. The controller is equipped with the capability of two auxiliary idle set points: Idle One and Idle Two.

To program either of the set points:

1. Press and hold down the Idle One Temp or Idle Two Temp key.

2. While holding down the key, use the Up-arrow or Down-arrow key to adjust the set point temperature.

3. Release all of the keys. The idle temperature has been set.

4. Program the other Idle temperature if desired by repeating 1 through 3 using the other Idle Temp key.

To run the fryer at an auxiliary idle set point:

• With the fryer in idle (not running a menu) press either the Idle One Temp or Idle Two Temp key.

The indicator light over the Idle Temp key will flash slowly. The fryer will run at the idle set point until you run a menu by pressing the

Start/Stop key or you press the other Idle Temp key.

Cancel a Menu

Canceling a menu stops the controller 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 oven.

• Press the Start/Stop key for 2 seconds. Heat outputs will switch off. The heat output indicator light will switch off. [`idLE] or time of day will be on the display.

Restart a Menu

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

2. Press the Start/Stop key.

92 ■ Watlow MiniChef 2000 Application 18

Based on its programming, the unit will run the menu in one of the ways described earlier.

Change Menus

1. With the controller in idle, select the menu you want to run by performing the procedure under “Select a Menu” earlier in this section.

2. Press the Start/Stop key. 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.
