MASTER PASSWORD
All passwords can be edited through
parameterisation. If you don't remember a
password, you can still parameterise the controller
and look up and/or edit the password via a master
password. To do that, follow these steps:
1. Switch off power supply (disconnect from mains
or switch off power supply unit)
2. Press buttons
UP, DOWN
and
SET
at the same
time
and switch on power supply again.
3. Now, a ("Challenge") number will be displayed
for approx. 5s.
In no case disconnect the controller from power
supply now. Otherwise, the number will become
invalid. Using this number, you can call our sales
staff, phone +49 711 68661-0 to request the
master password ("Response"). Enter this master
password in the 1st control level in
.
Important:
Even if you remember the password,
you
must
enter the master password here. If the
password is accepted, you will enter the parameter
selection levels and all passwords will be deacti-
vated. By pressing the
SET
button (display
)
you can switch to the relevant parameter level.
Now, the master password is no longer required.
The passwords will remain deactivated until the
controller is disconnected from power supply
again. In case you leave the parameter level now,
simply press the
SET
button in
in order to
access the parameter selection levels again.
