CAUSE
The input programmed with the Priming Float function is activated.
Alarm generated by the input programmed with the 'Start pressure switch' function active.
Alarm generated by the input programmed with the Pump pressure switch function not act-
ive after 1 minute with the motor running.
Alarm generated by the input programmed with the Pump pressure switch function active
for 1 minute with the motor not running.
Alarm generated when the maintenance hours of the relative interval reach zero. See menu
M08. Use the command menu to reset the operating hours and reset the alarm to zero.
Alarm generated by the input programmed with the "Partially open suction valve" function.
In this situation, the suction valve on the suction side is not able to deliver the maximum
flow rate required by the electric pump
Alarm generated by the input programmed with the "Delivery valve partially open" function.
In this situation the pressure-side valve is not able to deliver the maximum flow rate re-
quired for the sprinkler system
Alarm generated by the programmed inlet with the 'Sprinkler activated' function.
Alarm generated when the threshold set in parameter P02.20 is exceeded if there is an input
programmed with the 'Pilot pump active' function.
Alarm generated by the input programmed with the 'Pilot pump failure' function.
Alarm generated when the threshold set in parameter P02.21 is exceeded if there is an input
programmed with the 'Pilot pump active' function.
Alarm generated by the input programmed with the 'Drain pump failure' function.
Communication via RS-485 does not work correctly. Check wiring and communication
parameter settings in M11 menu.
During the automatic test (in ON-OUT mode) the pressure switch remains closed for more
than one minute.
Alarm generated by the input programmed with the 'Test valve' function.
The motor power is below the threshold set in P05.08.
The motor power is higher than the threshold set in P05.09.
The user alarm is generated by the activation of the variable or associated input via the M18
menu.
The following table shows all the functions that can be associated with INPn program-
mable digital inputs. Each input can then be set so as to have an inverted function (NO/
NC), to be delayed when energised or de-energised with independent settable times.
Some functions require an additional numerical parameter, defined with the index (x)
specified by parameter P09.n.02. See menu M09 Digital Inputs for more details.
Description
Input disabled.
Free user configuration To be used, for example, if the input is used in a PLC logic
Electric pump starting from pressure switch contacts.
Electric pump starting by priming float switch contacts.
Automatic mode exclusion selector.
Water reserve alarm.
Start periodic test
Locks command and write operations via serial port. Data reading is always possible.
Inhibits access to the programming menu.
