Multiple Inverter System Password - DAB PUMPS MCE-22/P Instruction For Installation And Maintenance

If a password is set, user navigation is admitted in all pages, but on any attempt to make modifications to a parameter, a pop-up
window is displayed, requesting entry of the password. The pop-up window enables the user to exit the window or enter the password
for access.
When the correct password is entered, the parameters remain unlocked and modifiable for 10'.
To cancel the password timer, enter the PW page and press + and - at the same time for 2 seconds.
On entry of the correct password, an opened padlock symbol appears, while on entry of the incorrect password will display a flashing
padlock symbol.
If the incorrect password is entered 10 times consecutively, the same padlock error symbol appears with inverted colours, to indicate
that no password will now be accepted until the unit is switched off and on again. After the factory settings are restored, the password
is reset to "0".
Any change to the password is applied when Mode or Set is pressed, and any subsequent change to a parameter requires entry of
the new password (e.g. the installer makes all settings with the default PW value = 0, and the last thing he/she does is to set the PW
so that the machine is totally safe without any further actions).
If a password is lost, there are two options to modify the inverter parameters:
Note down the value of all parameters, reset the inverter to factory settings; see paragraph 7.3. The reset operation deletes
•
all inverter parameters, including the password.
Note down the number on the password page, send an email with this number to the local service centre, and a new
•
password will be sent within a few days to unlock the inverter.

Multiple inverter system password

The parameter PW is one of the sensitive parameters, and therefore must be identical for all inverters to ensure inverter operation. If
there is already a chain with aligned PW, and inverter is added with PW=0, a request is displayed to align the parameters. In these
conditions, the inverter with PW=0 can implement the configuration including the Password, but cannot propagate this configuration.
In the case of unaligned sensitive parameters, the key parameter with relative value is displayed in the parameter alignment page to
aid the user in checking whether a configuration can be propagated.
The key represents a password code. Depending on the key correspondence, the user can check whether the inverters in a chain can
be aligned.
Key equal to - -
the inverter can receive the configuration from all
•
the inverter can propagate its configuration to inverters with key equal to - -
•
the inverter cannot propagate its configuration to inverters with keys other than - -
•
Key greater than or equal to 0
the inverter can only receive the configuration from inverters with the same key.
•
the inverter cannot propagate its configuration to inverters with the same key or with keys = --
•
the inverter cannot propagate its configuration to inverters with different keys.
•
When the PW is entered to unlock an inverter in a group, all inverters are unlocked.
When the PW is modified on one inverter in a group, the modification is applied to all inverters.
When password protection is applied to one inverter in a group (+ and – in the PW page when PW≠0), protection is applied to all
inverters (the password is required to apply any modifications)
