Page 35: Programming Steps
PROGRAMMING STEPS Step Description Heating Hysteresis When the temperature of the in-hopper product detected by the TEV probe reaches the set value, the heating elements are deactivated while the beater keeps on running. If the hopper temperature, detected by the TEV probe falls by 2°C (value programmable at this step) below the set temperature, the heating elements are reactivated to bring the product back to heating temperature. - Page 36 Discrimin.Temp. Anti-freezing is active from TEV temperatures lower or equal to the temperatures programmed at this step. In any case, the anti-freezing is always active if TGV <= - 30°C, regardless of TEV value. During anti-freezing the beater speed is increased to 2 for 30” (fixed). Set TGV Value of TGV probe beyond which hot gas heating is disabled.
- Page 37 Offset TEV This is the correction of TEV probe. With this step it is possible to calibrate the real hopper mix temperature. Check temperature in the hopper using a precise thermometer. If the value measured does not correspond to the value shown by the display, press Increase/Decrease button until the temperature shown by the display corresponds to the one read by the thermometer.
- Page 38 Alarm TES It enables (YES) or disables (NO) Safety Thermostat alarm. Alarm PR It enables (YES) or disables (NO) the Pressure Switch alarm. Temp. Display It enables (Yes) or disables (No) display of TEV, TGV, TER and TER2 temperatures during automatic cycles for 24 hours. The step returns automatically to No. In case of blackout during 24h, it is necessary to set this step again to Yes to display the temperatures again.
