MACHINE SPECIFIC FUNCTIONS
The specific functions of the machine are detailed below.
HOUR METER:
stores the count of hours the machine has been ON, with a 10 minutes resolution (the count displayed is in
hours). The count of hours is saved automatically every 10 minutes, so if the machine loses electric power
the maximum operating time lost in the ON state is 10 minutes. When an alarm occurs the hour meter
is saved immediately, so in case of loss of power supply immediately after an alarm nothing goes lost.
ALARMS / WARNINGS:
alarms and warnings are generated in the event of an anomaly only with the machine ON. To restore
them it is necessary to turn the machine off, enter the service menu - reset alarms and enter the appro-
priate password. After the restoration if anomaly conditions persist alarms / warnings will be generated
again when the machine is turned ON. Alarms not restored are re-activated in case of disconnection and
subsequent connection of the power supply.
ALARMS AND WARNING
Below is the list of alarms as they appear on the display:
• "W01 - DIRTY FILTER": dirty filter warning (threshold defined by the DIRTY parameter FILT. EDGE of the
factory menu, which can be disabled, only for the machines with analogic pressure switch or 600 h)
• "W02 - EXHAUST FILTER": warning of exhausted filter (threshold defined by the parameter
EXHAUST F. EDGE of the factory menu if function enabled)
