1-5. DIAGNOSTIC MODE DETAILS

The Chick-ﬁ l-A fryer controllers provide diagnostic functions that let an Operator review operating and performance data for the fryer.

The information provided by Diagnostic Mode can be used to monitor procedural errors, such as, not waiting for the READY light before starting a Cook Cycle, canceling cycles early, etc.

In addition, Diagnostic Mode allows slight adjustment to product color, reports the age and accumulated wear of the oil, and reports information about the performance of the line voltage supply.

Accessing Diagnostic Mode

To activate Diagnostic Mode, press button, then press

button.

The controller displays the following message:

“ *DIAGNOSTIC* “ “ *REPORT* “

are used to adjust the darkness setting.

To make the product darker, press to move the blinking “ * “ toward the DK (darker) side.

To make the product lighter, press to move the blinking “ * “ toward the LT (lighter) side.

When done adjusting, press to exit and return to normal operating mode.

Any temperature adjustment activated by the color adjustment feature will be reﬂ ected in the normal setpoint display as part of the offset from the basic product cook temperature. To view the present regulating temperature, press twice.

In the example, “SETPT = 315°F + 6” the product cook temperature is 315°F and has an additional offset of 6°F to compensate for the age of the oil, how long the fryer sits idle, and any color adjustments.

D 2: Oil Wear Report

This section displays information about the age of the present batch of peanut oil.

The ﬁ rst step shows how many days of use this oil has:

“D2: THIS OIL IS “ “D2: 4 DAYS OLD “

The controller only counts days in which the fryer is in use.

Press to move on to the second step. This step shows the age of the peanut oil by percentage of its expected lifetime. The peanut oil’s present, accumulated wear is compared to the wear setting at which the controller will prompt for the oil to be changed.

“D2: THIS OIL IS “ “D2: 16% USED “

This information can be used as the oil nears the end of its life (i.e. 95%), to plan ahead for when a clean-out will be required.

Press to move on to the next section.

D 3: Line Voltage Performance Report

This section displays information about how good the line voltage supply has been for the present day and for the present batch of oil.

The controller continually monitors the line voltage supplied to the fryer (when the fryer is on). If the line voltage drops below [90%] of its nominal value, the controller signals a “LOW VOLTAGE” alarm.

This alarm sounds at the end of each Cook Cycle for which low voltage has been detected. While not cooking, the low voltage alarm can sound as frequently as every 30 minutes.

“[ ]” around a value, such as [90%], means this value

is programmable and might change with later software versions.

Voltage Report for Today

If no low voltage warnings have been detected for the present day, the controller shows, “D3: VOLTAGE OK, D3: TODAY “

If one or more low voltage warnings have been detected for the present day, the following sequence example could be displayed:

“D3: YOU HAD 3”

“D3: LOW VOLTAGE”

“D3: WARNINGS”

“D3: TODAY”

Press to advance to the next section.

D 4: Heating Capacity Report

This section reports the present status of the heating system.

The controller examines a history of heat-up data and determines whether or not the heating system is operating normally. The heat capacity is said to be bad only if the most recent heat-up failed to meet the expected heat-up rate and three of the last four heat-ups also failed to achieve the expected rate. That is, a single slow heatup will not trigger a slow heat warning. The slow heat warning is activated only after repeated low-rate heat-ups is observed.

The controller can’t assess the integrity of the heating system if the fryer has been experiencing voltage problems. Low heat rates observed in this situation might be due to voltage problems rather than heater problems.

If the fryer has witnessed two or more low voltage warnings today, the following report is displayed:

“D4: CAN’T TEST”

“D4: HEA

T CAPACITY” “D4: DUE TO” “D4: VOLTAGE” “D4: PROBLEMS”

Otherwise, if the assessed heat capacity rating is presently “good” and there has been at most one heat-up today that failed to achieve the expected rate, the following report is displayed:

“D4: HEATING” “D4: CAPACITY”

“D4: IS FINE”

Otherwise, if the heat capacity is presently assessed as “bad”, or presently assessed as “good” but two or more heat-ups today have not reached the expected heat-up rate, the following report sequence is generated:

“D4: YOU HAD 75%” “D4: SLOW HEATS”

“D4: TODAY”

“D4: HAVE 20%” “D4: SLOW HEATS”

“D4: THIS OIL”

If the heat capacity is assessed as bad (low heat-up rate on last heat-up, and on three of the last four heat-ups), then the heating coils are suspect and the following message is displayed:

“D4: CHECK COILS,” “D4: CONTACTORS,”

“D4: AND WIRING”

D 5: Cook Times (Slow Cooks) Report

This section summarizes the slow cooking status for each product.

Actual cook times for Cook Cycles can vary from the programmed cook time setting, due to the load compensation feature. Load Compensation slows the cook timer down when the actual peanut oil temperature is below a reference value, and speeds up the cook timer countdown when peanut oil temperature is above the reference.

When the peanut oil temperature is lower than expected during a Cook Cycle, the overall cook time will be longer than normal. If the actual cook time stretches beyond a programmed limit, the controller counts a “SLOW COOK” event and sounds an alarm at the end of the Cook Cycle.

If low voltage or low amps are detected during the Cook Cycle, the warning message indicates “LOW VOLTAGE” or “LOW AMPS”, but the cycle will still count as a “slow cook”. If the voltage and amps have been ﬁ ne during the Cook Cycle but the cycle was started before the Ready light came on, then the warning message indicates “SLOW COOK — WAIT FOR READY LIGHT”. Otherwise, the slow cooking problem will be attributed to a “bad batch” of product: cooking too much in one load, or cooking product that is too cold (i.e. frozen product on a pressure fryer when the product should be fresh).

If none of the products has more than 5% slow Cook Cycles today, the following report is made:

“D5: COOK TIMES” “D5: LOOK OK” “D5: TODAY”

305 1-23

Model 500/600

1-5. DIAGNOSTIC MODE DETAILS (Continued)

Otherwise, if one or more cook products have generated a slow cook warning more than 5% of the time, but four or more low voltage or slow heat-up warnings (any combination) have been generated today, then the report is as follows:

“D5: SOME SLOW” “D5: COOKS

TODAY” “D5: MAYBE DUE TO” “D5: VOLTAGE OR” “D5: COIL PROBLEMS”

Such a report is saying the slow cooking may be the result of low voltage (which signiﬁ cantly reduces heat capacity) or the result of other problems with the heating system. In this case, the slow cook problems might not have anything to do with user error.

Otherwise, the slow cooking is generally attributed to user error: cooking too much product in one load, cooking frozen product (in the pressure fryer) when it should be fresh, or cooking before the Ready light illuminates, etc.

An individual “XXXXX IS COOKING SLOWLY TODAY” report item is generated for each product that has had more than 5% slow cook warnings today. This report item is triggered based solely on the number of slow cooks for that product, whether those slow cooks are due to voltage or heating problems, or due to cooking before ready, cooking too much, or cooking frozen product.

If any of the slow cooks for this product are suspected as being due user error, a second, “bad batch” report is generated for the product.

D 6: “Cooked Before Ready” Report

This section shows how many Cook Cycles were started before the READY light was on. This is strictly a user error.

If the fryer was in the ready range when the user begins to load product, but is out of the ready range by the time the Cook Cycle is started, the control will not give you an alarm.

If the fryer wasn’t ready before loading, an alarm sounds and

“WAS NOT READY” warning is generated. The number of times

this has happened today is indicated by the following report item:

“D6: COOKED” “D6: BEFORE READY” “D6: 11 TIMES” “D6: TODAY”

The number of “WAS NOT READY” warnings for this batch of peanut oil is also reported. Note that this value does not yet include the not ready warnings generated today.

“D6: BEFORE TODAY,” “D6: COOKED” “D6: BEFORE READY” “D6: 8

“D6: ON THIS OIL”

Finally, the controller identiﬁ es how many times the not ready warning was generated for the previous batch of peanut oil:

“D6: LAST OIL,” “D6: COOKED” “D6: BEFORE READY” “D6: 24 TIMES”

D 7: “Stopped Too Soon” Report

This section shows how many Cook Cycles were stopped early by the user, before the cook timer had counted down to 0:00 and the

“*DONE*” indication was given. This is strictly a user error.

Cycles that are canceled after cooking for less than 30 seconds are not counted here. For example, if a cycle is accidentally started, and the Cook Cycle is canceled after just a few seconds, this cycle will not be counted as a Stopped Too Soon Cycle.

Also, some allowance is given for stopping a cycle a little early.

The user can cancel the cycle up to 10 seconds early without penalty.

Otherwise, however, any cycle that was stopped with more than 10 seconds remaining (0:10) on the cook clock with be counted as a Stopped Too Soon Cycle.

The ﬁ rst item displays what percent of cycles today were stopped with more than 0:10 remaining. All products are grouped into one count.
