6.1 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 ( ) goes out and the system returns to normal operation.
Instead, if the error condition remains, you must take steps to eliminate the cause of the fault.
6.2 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 ( ) goes out
and the system returns 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.
6.3 Viewing the block history
The list of the faults and blocks that have occurred most recently can be consulted under the menu item “
Fault History
”.
See paragraph 5.11.
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 6.1.
