Auto-tuning Note:

Before auto-tuning Application 12, [teNp1] in the operations menu must first be set to a value that is typical of your application. (See the Hardware & Software Setup Guide for information on programming menus.) Then set [tHerl] / [tunE1] to [```on].

After you accept [```on], by pressing “Enter,” the controller will display [`tunE] while auto-tuning is taking place.

The controller will cancel the auto-tuning process if it cannot be completed in 80 minutes. You can cancel the auto-tuning process at any time by pressing either key C or key

D and accepting [``Off], by pressing “Enter,” when it appears.

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.

AT OPERATING TEMPERATURE

(PREHEAT CONDITION MET)

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 (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 inactive — in other words, when the [ready] parameter in the [setUp] function of the

Configuration Mode is set to [``yes] .

1.

Set the cooking time and temperature as shown earlier.

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

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.

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 control operation in order to run another one, to stop control operation for any reason, or when preparing to shut off the fryer.

• Press the Start/Stop key 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 or Restart Menus

1.

Set time and temperature as shown earlier.

2.

Press the Start/Stop key.

Manual Basket Lift

You can raise or lower the basket manually at any time by pressing the Down-arrow key

(to lower) or the Up-arrow key (to raise). If you raise the basket while cooking, the timer will pause. Countdown time will resume when you lower the basket or when you press the active menu key.

ç

WARNING: The Basket Up and Basket Down Keys cause or initiate motion. Appropriate reasonable care should be taken to prevent personal injury or machine damage as a result of operator initiated or unexpected machine motion.

Event Outputs

While running a menu:

Event output 1 is activated to lift the basket for the length of time programmed in

Configuration Mode [EtyPE] / [btinE].

Event output 2 is activated to lower the basket for the length of time programmed in

Configuration Mode [EtyPE] / [btinE].

Only one output can be on at a time.

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
