If there is an HA or HF alarm, a alarm reset can be performed or you can completely delete the alarms and
status recording:
1
To reset the buzzer and deactivate the alarm relay (if present), just press Button 1 for 1 second.
The HA or HF alarm code remains on the display along with signalling by turning on the LED for the HACCP
button.
2
Pressing Button 1 for 5 seconds completely deletes the saved alarm and also resets the button backlight
LED.
The same function can be performed by zeroing out the parameters in the three-button terminals.
12.2.3 I.C.C. (Intelligent Check Control) COMPRESSOR BLOCK ALARMS
Cb alarm:
Signals a compressor block due to the maximum pressure switch or compressor thermal switch.
Reset or Cb Alarm:
If a Cb alarm occurs, you cannot reset the signal.
The alarm is automatically eliminated by removing the cause:
- The pressure switch is automatically rearmed (when the condensation pressure decreases)
- The thermal switch is manually rearmed (see photo 001)
12.2.4 ASC (Automatic Set Control) FUNCTION
The appliance automatically varies the SET-POINT based on the position of the rear slider, thus allowing
optimal maintenance of the ice cream.
IMPORTANT WARNING
During the parameter modifi cation procedure, pressing Button 8 for 5 seconds switches from temporary
saving of the changes to the fi nal save.
If power is removed from the instrument before pressing Button 8, all changes made and temporarily
saved are lost.
For complete memorisation, the control must remain on for another 60 seconds.
EXITING THE PROCEDURE WITHOUT CHANGING THE PARAMETERS
To exit without changing the parameters, do not press any button for at least 60 seconds (TIME-OUT exit)
In this manner, the instrument returns to its normal operation.
12.2 HACCP FUNCTIONS
12.2.1 ALARMS
HA alarm
This advises if the regulation temperature is greater than a maximum value for a length of time that is greater than
the set delay time.
The threshold value corresponds to the value set on the instrument for the high temperature alarm (SET + AH). The
delay time corresponds to the sum of the times set with two parameters: Parameter AD and parameter tr.
HF alarm
This signals a lack of power for a prolonged period of time (greater than 1 minute) with a temperature when the
power returns that is greater than the maximum set value (SET + AH).
In both cases, the alarm code appears on the display along with the HAACP button LED lighting up and activation of
the alarm or buzzer relay (if present).
12.2.2 RESET OR CANCEL ALARMS
