PROTECTION SYSTEMS – LOCKS (FAULT)
The device is equipped with protection systems to preserve the pump, the
motor, the supply line and the inverter. If one or more protections trip, the
one with the highest priority is immediately notified on the display.
Faults cause switching off of the motor and lighting of the red warning LED
(
).
In some types of fault, the motor restarts as soon as normal conditions are
restored; in others, attempts at automatic reset are carried out after a certain
space of time.
It is also possible to try to cancel the error condition manually (see the
following paragraphs). If the error condition remains, you must take steps to
eliminate the cause of the fault.
7.1 Manual reset of error conditions
In block (fault) status, the user can cancel the current error and force a new
attempt by pressing and releasing the "Reset" key.
If the action is successful, the red warning LED(
system returns to normal operation. Instead, if the error condition remains,
you must take steps to eliminate the cause of the fault.
7.2 Automatic reset of error conditions
For some types of fault, automat reset attempts are contemplated. In particular
for:
-
e27
Dry operation
-
e28
Pump not primed
a new attempt is made after a few minutes, and repeated cyclically.
If an attempt is successful during the reset sequence, the sequence is interrupted, the red warning LED (
to normal operation.
In the case of the "Excess temperature" faults, the system resume operation as soon as the temperature returns within the normal operating
range.
For the error "e33 SVRS trip", see paragraphs 1.3 e 7

FACTORY SETTINGS
The system leaves the factory with a series of preset parameters, which may be changed according to the requirements of the plant and of
the user. Each change of the settings is automatically saved in the memory.
The factory (or default) settings are summed up in the following table. You can make a note of the values modified for your own installation in the
"MEMO" column.
As indicated in the table, some default values may differ depending on the market for which the system is intended.
If desired, it is possible to restore the default settings, proceeding as described in paragraph 8.1.
