Each change of the password takes effect when Mode or Set is pressed
and each subsequent change of a parameter implies typing in the new
password again (e.g. the installer makes all the settings with the default
PW value = 0 and lastly sets the PW so as to be sure that the machine is
already protected without any further action).
If the password is lost there are 2 possibilities for editing the parameters
of the device:
• Make a note of the values of all the parameters, reset the
device with the factory values, see paragraph 0. The reset
operation cancels all the parameters of the device, including the
password.
• Make a note of the number present on the password page,
send a mail with this number to your service centre, in a few
days you will be sent the password to unlock the device.
7.6.21.1 - Password for multipump systems
When the PW is typed in to unlock a device in a set, all the devices are
unlocked.
When the PW is changed on a device in a set, all the devices receive the
change.
When activating protection with a PW on a device in a set (+ and – on
page PW when PW≠0), the protection is activated on all the devices (to
make any change you are asked for the PW).
8 - RESET AND FACTORY SETTINGS
8.1 - General system reset
To reset the system, hold down the 4 keys simultaneously for 2 sec. This
operation is the same as disconnecting the power, waiting for it to close
down completely and supplying power again. The reset does not delete
the settings saved by the user.
8.2 - Factory settings
The device leaves the factory with a series of preset parameters which
may be changed according to the user's requirements. Each change of
the settings is automatically saved in the memory and, if desired, it is al-
ways possible to restore the factory conditions (see Restoring the factory
settings par 8.3 – Restoring the factory settings).
8.3 - Restoring the factory settings
To restore the factory values, switch off the device, wait until the display
has switched off completely, press and hold down the "SET" and "+" keys
and turn on the power; release the two keys only when the letters "EE"
appear.
This restores the factory settings (a message and a rereading on EE-
PROM of the factory settings permanently saved in the FLASH memory).
Once all the parameters have been set, the device returns to normal
operation.
NOTE: Once the factory values have been restored it will be necessary
to reset all the parameters that characterise the system (gains, setpoint
pressure, etc.) as at the first installation.
