Frozen Condition: The coriolis interface board monitors the temperature at the

solenoid valve using the temperature sensor known as the frozen thermostat. The

purpose is to remove power to signal the 9800 CPU board not to active the solenoid

valve on the coriolis meter. This prevents the solenoid valve to potentially leak and

also prevent damage to the coriolis meter.

The CR5 LED on the coriolis interface board will light when a freeze condition

exists, which is normally caused by other component failure, causing the heaters

not to turn on as shown Figure 4-1.

Calibration Test: When the freeze problem has been

corrected and the heater/fans are working, to keep the inside

cabinet temperature in 30° F (-1.1° C) range or higher, you

need to recalibrate the unit to remove the error message 999

displayed.

Symptoms: In very cold weather conditions, the display shows 999 and is unable to dispense product.
