TROUBLESHOOTING

4.1 ERROR CODES

The following error condition codes will display on the control panel when the freezer is experiencing a problem. The error condition code directs you to the system location of the malfunction.

ERRORCODE

MALFUNCTION

01

Program Board

02

High Torque Error

03

Extended Run Time Error

04

Clean Error

05

Freezing Cylinder Sensor

07

Drive Motor Current

09

12

Left Hopper Sensor Error

13

Right Hopper Sensor Error

Any error causing condition must be corrected, then the power turned off, and back on before the freezer will return to normal operation.

4.2 UNDERSTANDING ERROR CODES

ERROR CONDITION CODE 01

If the control panel displays a program board error (Error Code 01), place the Freezing Cylinder Off-On Switch in the Off position, wait 10 seconds, and return the switch to the On position. If the Control Panel still displays the error condition code, call your Authorized Stoelting Distributor for further assistance.

ERROR CONDITION CODE 02

If the control panel displays a high torque error (Error Code 02), the controller has sensed that the product in the freezing cylinder has reached 125% of set consistency for 10 or more seconds. This condition may be caused if the product consistency adjustment has been set too high. To remedy this condition, place the Freezing Cylinder Off-On Switch in the Off position, wait until the product in the freezing cylinder has had adequate time to thaw to a reasonably soft consistency, and return the switch to the On position. Follow the Product Consistency Adjustment procedures at the begining of this section and reduce the Fine Adjustment value by a few points. If the Control Panel still displays the error condition code, call your Authorized Stoelting Distributor for further assistance.

ERROR CONDITION CODE 03

Extended run time errors (Error Code 03) are often times caused by the mix running too low in the freezer’s hopper, or if a restriction is preventing the mix from entering the freezing cylinder. Check the mix level on the affected freezing cylinder. If the level mix is low, add mix. Look for ice crystals in the liquid mix in the hopper. Ice crystals can clog the mix inlet regulator, and prevent mix from entering the freezing cylinder. If you find ice crystals in the mix, check the temperature of the walk-in cooler where the mix is stored.

Excessive compressor run time may also occur if the condenser filter is dirty, or if the condenser is obstructed. Check around the sides of the freezer, to be sure nothing has been placed near the condenser vents. A minimum of 3" clearance is required.

After the cause of the problem is found and remedied, place the Freezing Cylinder Off-On Switch in the Off position, wait 10 seconds, and return the switch to the On position. If the Control Panel still displays the error condition code, call your Authorized Stoelting Distributor for further assistance.

ERROR CONDITION CODE 04

If the freezer is left in the Clean Mode for more than 20 minutes, the control panel will display a Clean Error (Error 04). This condition does not reflect a problem with the freezer itself. The Clean Error has been programmed into the controller as a safeguard to protect the freezer from potential damage caused by the freezer being accidentally left in the clean mode. To remedy the Clean Error, place the Freezing Cylinder Off-On Switch in the Off position, wait 10 seconds, and return the switch to the On position. If the Control Panel still displays the error condition code, call your Authorized Stoelting Distributor for further assis- tance.

ERROR CONDITION CODE 05

If the control panel displays a Freezing Cylinder Sensor error (Error Code 05), place the Freezing Cylinder Off-On Switch in the Off position, wait 10 seconds, and return the switch to the On position. If the Control Panel still displays the error condition code, call your Authorized Stoelting Distributor for further assistance.

NOTE

When the freezer encounters a Freezing Cylinder Sensor Error, the freezer will automatically be switched to run on pre-configured timing cycles. This mode will allow you to continue serving product until the freezer can be serviced.
