1.8.4 Improper Computer Function

Sensitivity or "Stretch Time." Sensitivity—or stretch time—is a programmable feature that increases the cook time countdown based on variations in the oil temperature from the setpoint (e.g., when cold product is dropped into the oil, causing the oil temperature to drop).

The sensitivity for each product button has 10 settings (0 through 9). A "0" sensitivity setting will disable the feature (no change in cooking time), while a nine will provide the highest sensitivity or the most change. The correct sensitivity for any product is based on the product type, its density, the setpoint temperature, and the customer’s own requirements.

Common Computer Complaints. Most problems concerning computers have to do with programming them. There are four common complaints. The complaints, their causes, and corrective actions are as follows:

1.Fryer constantly displays "". Cause: Setpoint incorrect or missing.

Corrective Action: Press 1 6 5 0, enter the correct setpoint using keypad, then press and then this to lock in the setpoint.

2.Temperature is displayed in Celsius.

Cause: Computer is programmed to display in Celsius.

Corrective Action: Press 1 6 5 8.

3.Temperature is constantly displayed.

Cause: Computer is programmed for constant temperature display.

Corrective Action: Press 1 6 5 L.

4.Computer times down too slowly or too quickly.

Cause: Computer is compensating for oil temperature via the sensitivity setting.

Corrective Action: Reprogram sensitivity setting for each product in accordance with programming instructions in the Compu-Fry Operation and Programming manual, P/N 819- 5865.
