5.0 START-UP AND CONTROL PANEL
After identifying the cause of the alarm and making the consequent checks, modifications or resets, please follow the procedure to reset the
alarm:
-
The ALARM button is flashing. This means that at least one alarm is active
-
Press the ALARM button to access the alarm screen
-
Use the UP and DOWN keys to move to the screen showing the alarm to be reset
-
To reset the alarm displayed, press the ALARM button again
-
If the ALARM button is pressed for at least 3 seconds, all of the active alarms are reset
-
If the cause of the alarm hasn’t been
completely resolved, it will be signalled again after reset
-
To return to the main menu of the microprocessor, simply press ESC
5.4.2 ALARM TABLE
The following table shows a complete list of the alarms that can be found on the microprocessor with a code of reference, an explanation of the
fault and the reset system (before resetting the alarm, it is necessary to eliminate the cause):
In the event of a fault, the microprocessor
“Alarm”
button will flash. This means that there are faults compared to normal operation. To display
the alarm, refer to the procedure in the previous paragraph.
