FAILURE TO FILL PIPES FAULT
The acceleration starts with the engine running, with pump primed.
The motor pump reaches the redefined WORKING PRESSURE (see
BARS STORED
) within the TIME OF FAILURE TO
FILL PIPES, set to 120 seconds. If air is present in the pipes, the acceleration will be alternated with pauses (of 15 seconds), if
the pressure remains steady for 5 seconds. This situation will be repeated several times until the WORKING PRESSURE is rea
-
ched. If the pressure is not reached within the FAILURE TO FILL PIPES time (120 sec.), FAILURE TO FILL PIPES is displayed
on the display and the engine stops.
ABNORMAL ACCELERATION
(Pipe leakage controlled within the limits of the system).
As a result of a leakage, the engine tends to increase the revolutions to bring it back to WORKING PRESSURE. If the revolutions
increase by 10% for a time longer than 120 seconds, ABNORMAL ACCELERATION is displayed on the display and the engine
stops

The pump protection is enabled when warning lights PUMP PROTECTION ACTIVE and water pressure normal come on
after the water pressure has remained stable for 2 consecutive minutes, in any case 10 minutes after the engine started.
Intervention of the protection (5 seconds after the pressure goes up or down by
