Master password
All passwords can be changed by parametrisation. If the user forgets the password, it is
still possible to parametrise the controller via a master password and, in particular, to
check and/or change the forgotten password. This requires the following steps:
1. Switch off the power supply to the controller (disconnect from the mains or switch off
the power supply unit).
2. Press the
UP
,
DOWN
and
SET
keys simultaneously and switch on the power supply
again.
3. A ("challenge") number now appears on the display for approx. 5 s. Do not disconnect
the controller from the power supply now because this would invalidate the number.
Use this number to call our sales department, Tel. +49 711 68661 0 and receive the
master password ("response"). Enter this master password at the 1st operating level
for
PA
.
Important: Even if the user has not forgotten this password, the master password must be
entered here. If the password is accepted, the user is in the parameter level selection and
all passwords are deactivated. The user can change to the corresponding parameter level
simply by pressing the
SET
key (
---
display).
The master password is no longer required. The passwords remain deactivated until the
controller is disconnected from the power supply. If the user leaves the parameter level, it
is sufficient to simply press the
SET
key for
PA
to return to the selection of the parameter
levels.

block the control system. The control system is not enabled until the error has been eliminated. The error(s)
EP0
(and
