This section provides programming procedures for the Computron 7000. The operational controls should be read and understood to become familiar with the control and its functions. If technical assistance is needed, refer to the toll free number printed in this manual.

It is recommended to fill out the program worksheet that was shipped with the unit before programming. This will result in less confusion when programming the control.

1. Move the keyswitch to the PROGRAM position.

2. Depress the SELECT PRODUCT switch to the desired product. The red indicator light will illuminate beside the particular product you are programming.

3. By depressing the SELECT FUNCTION switch, you pick the function to program such as time, temperature, etc. The function you are in will be flashing. Program TIME first.

4. Depress the change switches beneath the digital display until the desired time is displayed. Example: 11 minutes

- 11:oo.

5. Continue this procedure until you have programmed TIME,

TEMPERATURE, ALARM, and PRESSURE.

An alarm cannot be programmed on the first interval of any product. Also, your programming temperature range is from 170° to 390OF.

6. By depressing the SELECT TIME switch you can change intervals within that function. You may program up to 10 intervals per function.

7. Load compensation, load anticipation, proportional control,

and filter cycle can only be programmed in interval one.

When changing to interval two, only time, temperature,

alarm, and pressure will illuminate in the function display.

Load compensation, although factory preset, is programmable. Load compensation adjusts cooking times to compensate for differences in the cooking process such as load size. The control is continuously comparing the pot temperature to the setpoint temperature. If the pot temperature is above the set point, then the control will shorten the cook time. If the pot temperature is below the setpoint, then the control will lengthen the cook time. This is programmable within this

function by displaying 0 to lO..qero meaning no load compensation, while ten means the highest load compensation.

When dropping a large load of product into the fryer, there is a large temperature drop. On normal controls there is a time period before the thermostat senses this drop. With load anticipation this time period is avoided by turning the heat on as soon as the timer is activated. The heat will remain on until the control senses that the temperature is increasing at which point normal heat control takes over. When programming, the display will read 00 to lOOF. For example: if 5 degrees is programmed, this means the temperature cannot exceed five degrees above setpoint temperature before normal heat control takes over. This is a safeguard or a temperature limit.

Proportional control regulates pot temperature by pulsing the heat until it reaches setpoint temperature. This allows tighter regulation of pot temperature and also eliminates the “override” of setpoint temperature. The control can be programmed

0 to 30 degrees; zero being no proportional control (best recovery time) and up to thirty degrees meaning the control will pulse the heat off and on thirty degress before it reaches

setpoint (best temperature regulation). Since each product can be programmed with a different proportional control factor, temperature accuracy and recovery time can be tailored to each

food product.

The filter cycle count is a method of keeping track of when

it is time to filter the shortening. To determine when it is time to filter, the control adds the (fractional) number of the cycle count to a running total at the end of each cook cycle. When this total exceeds one, then the “FIL” (“FIL” within the digital

display) indication is given. An example of this would be as follows:

et Chicken Fish Potatoes Vegetables

If the operator cooked one cycle of chicken, one cycle of fish, and one cycle of potatoes, the unit would indicate to filter since 114 I- l/3 + l/2

= 1 l/12 which is greater than one. In the event the unit cannot be filtered at the proper time the filter program mode may be bypassed. Turn the power switch to OFF for at least 5 seconds, then turn the unit back to the COOK position. Filter will be bypassed and unit will return to programmed 1st cycle.

The idle modes main function is to lessen the breakdown of shortening, by programming a lower temperature, when the unit is not in use. The idle mode can be selected by depressing the SELECT PRODUCT switch until the idle mode is indicated. Automatic idle is enabled by programming “A” in the display. Also, the idle time can be programmed. This means the control will select idle automatically after the programmed time has elapsed.

If automatic is not programmed, idle must be selected manually. Idle time is programmed from 0 to 255 minutes.

When this is programmed the type of idle can be selected:

cycle idle or time idle. This is indicated with a “6” or “T”. In cycle idle the programmed time is started every time a new product is selected. In timer idle the programmed time is started at the end of each cook cycle. Depress the SELECT FUNCTION switch. A “C” or “T” will be displayed’indicating cycle idle or time idle. Also, the idle temperature can be programmed from 170°F to 3900F. This is normally set at 250OF.

The following are four examples of the idle mode. Example 1: AUTOMATIC IDLE - idle temperature is 250’JF

and the idle time is 30 minutes. Control is programmed in eye idle. If no product is cooked within 30 minutes, control will automatically select IDLE and regulate at 250OF.

Example 2: AUTOMATIC IDLE - idle temperature is 250°F and the idle time is 30 minutes. in idle. Several loads of differen

A as no more than 30 minutes pass between product selections, the control will not select idle.

Example 3: AUTOMATIC IDLE - idle temperature is 250°F and the idle time is 30 minutes. Control is programmed in time

le. A product is selected and several loads are cooked. As long as a load is cooked within 30 minutes of the last load, the control will not go into idle. If 30 minutes pass between loads, the control will automatically select idle.

Example 4: AUTOMATIC IDLE IS NOT PROGRAMMED control in manual idle. The control will remain in the product selected by the operator. Operator must use SELECT PRODUCT switch to enter idle mode.

The melt mode is used to safely melt solid shortening and can also be used with liquid shortening. Gradually heating or melting the shortening greatly extends its life. This is automatically accomplished in the melt mode by turning the

heat on for 3 seconds and off for 27 seconds. The operator has

the option of entering melt manually with the SELECT PRODUCT switch or programming automatic melt. Select the melt mode and program “A” for automatic. At this time also program the melt temperature. This is the temperature the control will exit the melt mode and go into the heat mode. It is recommended to program this temperature at 170OF. After programming, the control will work as follows: when the unit is turned on the control checks the pot temperature. If the pot temperature is below 1 70°F or programmed temperature, the unit will enter the melt mode. If the pot temperature is above 1700F or programmed temperature, the unit will enter the programmed 1 st cycle.

Once pot temperature exceeds the programmed melt

temperature the melt mode cannot be entered.

While in the melt mode, the first cycle can also be pro This is the cycle the control will automatically select when in COOK upon exiting the melt mode. It is programmed ing the melt mode and depressing the SELECT FU switch. The green 1st cycle light will flash and the temperature light in the function display will be on. The left half of the product display are numbered from top to botto right half are numbered 7 to 10. Melt and numbered. However, idle can be selected as th number one of the product display is desired as first cycle, program a number one. If number eight of the product display is desired, program number eight.

An unprogrammed product cycle cannot be selected as the first cycle.

The one button programming feature is a simple way for the operator to place Henny Penny’s cooking parameters into the control’s memory. These programmed cooking cycles are matched with the menu item cards sent with each unit. To achieve this one button programming, follow these steps:

1. Turn the COOK/PROGRAM keyswitch to the PROGRAM position.

2. Depress the TIMER switch. This will put you into the Special Program Mode. The display will read “SP”.

3. Using the SELECT PRODUCT switch, select the number 7 product (this will be the top right menu item). The display

will read as follows: Digit

Digit 1: Blank’ -’ When the switch under the digit is depressed it will read INIT for one second then ‘erase all memory.

Digit 2: Blank - When the switch under the digit is depressed it will enter all Henny Penny cooking parameters. Display will read INIT for one second, then HP.

Digit 3: Display will read either F for Fahrenheit degrees or C for Celcius degrees. By depressing the switch under

the digit, it will toggle from F to C.

Digit ‘4: Display will read either E for electric or 0 for gas units. By depressing the switch under the digit ‘it will toggle from E to 0.

This feature will aid the operator in the event there is a power outage. If the control is timing down and the power supply is interrupted for any reason, the control will not reset to the

original cook cycle time, When power is restored, the control will resume timing at the point the power was interrupted, allowing the operator to know what time is needed to finish cooking that particular’ load of product.

The unit has a boil out mode which is factory pre-programmed. To enter the boil out mode, follow the instructions below.

1. Place keyswitch in the COOK position.

2. Depress the SELECT PRODUCT switch and select either IDLE or MELT.

3. Depress the TIMER switch.

4. Display will read Y for yes or N for no.

5. If you desire to enter the boil out mode, depress the switch below Y. Control will heat to factory’s pre-programmed boil

out temperature.

6. If, for any reason, you do not wish to enter boil out

mode, depress the switch under N.

7. After boil out is complete, turn power switch to the OFF position and drain contents from unit.

R TO CLEAN. Leave lid open. Water under pressure is super heated and will cause severe burns if it comes in contact with skin.

1 1. Be sure keyswitch is in the CO ~ 2. Turn the power switch to the cook position.

3. Select desired product using the SELECT P switch. The red indicator will be illuminated beside
