Programming

Degrees Displayed in Fahrenheit or Celsius

This setup option affects the programming and display of all temperatures. If “FAr” is selected, all temperatures will display in Fahrenheit. If “CEL” is selected, all temperatures will display in Celsius. Acceptable ranges for programmable temperatures are 75° – 200°F or 25° – 93°C.

Procedure for Temperature Calibration

1.Ensure that the V-Computer has no input power applied.

2.Mount an accurate temperature sensor probe (part of temperature calibration equipment) in the bottom of the machine basket. Make sure the wires for the probe exit the top of the door to ensure the door gasket does not leak.

3.Close door and ensure that the door is locked.

4.Open machine top cover and remove control component cover(s), if necessary, to gain access to the V-Computer and output control board.

NOTE: For more accurate calibration proceed with steps 5-9. For a quick estimated calibration skip to step 10.

WARNING

Dangerous voltages are present in the electrical control box(es) and at the motor terminals. Only qualified personnel familiar with electrical test procedures, test equipment, and safety precautions should attempt adjustments and troubleshooting. Disconnect power from the machine before removing the control box cover, and before attempting any service procedures.

5.Note wire connections on the output control board for the AC Drive control. Some machines will have six wires connected to “STF,” “STR,” “RH,” “RM,” “RL,” and “COM” individually or a single connector labeled “J11-1.” Remove these wires or connector to ensure the basket will not rotate. Also remove the input power to the drive.

NOTE: If this step is not followed, damage can occur to the calibration temperature probe.

WARNING

NEVER insert hands or objects into basket until it has completely stopped. Doing so could result in serious injury.

6.Restore input power to the machine.

7.Wait until machine message displays “CY” followed by a two-digit cycle number (01 – 30).

8.Program one of the unused cycles to Fill to High Level using both of the water inlet valves. Select a time limit that would be sufficient to complete the calibration procedure.

9.When machine has completed the Fill to High Level, press and hold the Up key to display the machine temperature. Make sure that the V-Computer is in the correct temperature unit (deg F or C). Refer to Setup Mode section of manual to change.

10.Using a flat bladed screwdriver, turn the machine temperature calibration screw until the displayed temperature of the machine and the temperature of the temperature calibration equipment are accurate to the nearest degree (refer to Figure 4).

11.When the temperatures match, calibration is completed.

12.Remove power from the machine input.

13.Reconnect any wires/connectors/fuses that were removed, making sure they are installed exactly as they were removed.

14.Reinstall all machine protective covers.

15.Remove the temperature calibration probe from the bottom of the machine basket.

16.Restore input power to machine.

17.Machine is now ready for use.
