Protection Systems - DAB ACTIVE DRIVER PLUS M/T 1.0 Installations- Und Wartungsanleitungen

6.6.20 PW: Change password
The device has a password-enabled protection system. If a password is set, the parameters of the device will be
accessible and visible but it will not be possible to change them.
The only parameters that allow the password to be changed independently of the setting are: SP, P1, P2, P3, RP, FP,
LA, CT, MS.
When the value is modified, the parameter symbol starts to blink, indicating that the value has changed. The
modification will be effective only when [SET] or [MODE] is pressed or when the menu is changed. If you do not press
any key after having changed the parameter and leave the page by timeout, the change will not be effective.
When a password is used (value of PW different from 0) all modifications are blocked and "XXXX" is displayed on the
page PW. If the password is set it allows to navigate through all the pages, but at any attempt to edit a parameter a
pop-up appears, asking you to type in the password. When the correct password is typed in the parameters are
unlocked and can be edited for 10' after the last key is pressed.
If you want to cancel the password timer, just go to page PW and hold down + and – together for 2".
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 8.3. 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.
6.6.21 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).

7 PROTECTION SYSTEMS

The inverter is equipped with protection systems designed to preserve the pump, motor, power line and the inverter
itself. When one or more protections trip, the one with the highest priority is shown on display. Depending on the type
of error, the electric pump may shut down, but when normal conditions are restored, the error state may clear
automatically, immediately or after a set time interval following automatic reset.
In the case of a block due to water supply failure (BL), block due to pump motor current overload (OC), block due to
final output stage current overload (OF), block due to direct short circuit between the phases on the output terminal
(SC), the user can attempt to manually reset the error condition by pressing and releasing buttons + and -
simultaneously. If the error condition persists, the cause of the fault must be located and eliminated.
