When the correct password is typed in a padlock is shown opening, while
if the wrong password is given a flashing padlock appears.
After resetting the factory values the password is set back at "0".
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
The PW parameter is one of the sensitive parameters, so for the device
to work it is necessary for PW to be the same for all the devices. If there
is already a chain with an aligned PW and a device is added with PW=0,
the request to align the parameters will be made. In these conditions the
device with PW=0 can assume the configuration including the Password,
but it cannot propagate its own configuration.
In the case of sensitive parameters that are not aligned, to help the user
understand whether a configuration can be propagated, the key param-
eter with respective value is displayed on the parameter alignment page.
The key represents a coding of the password. Depending on the cor-
respondence of the keys, it can be understood whether the devices in a
chain can be aligned.
Key equal to - -
the device can receive configuration from all
•
it can propagate its own configuration to devices with key equal
•
to - -
it cannot propagate its own configuration to devices with key
•
different from - -
Key greater than or equal to 0
the device can receive configuration only from devices that have
•
the same key
it can propagate its own configuration to devices with the same
•
key or with key = - -
it cannot propagate its own configuration to devices with a differ-
•
ent key.
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
