Password Forgotten
By pressing the »Ack/Rst« key during a cold restart a reset dialog is launched. It allows for
resetting all passwords to the default »1234«. See
╚═▷ “Reset to Factory Defaults, Reset
General Considerations
You have to ensure that the access authorizations are protected by secure passwords.
These passwords have to be kept as a secret and to be known only by the authorized
persons. The default password “1234” does not provide any security against
unauthorized access.
A lock symbol in the upper right corner of the display indicates if there are any access
authorizations active at the moment . That means, within the mode “Read Only-Lv0” a
closed (locked) lock symbol will be shown in the upper right corner of the display. As soon
as there are any access authorizations active (above the “Read Only-Lv0” level), the
upper right corner of the display will show an unlocked (open) lock symbol.
During setting parameters the »Ack/Rst« key can be used for canceling the parameter
changes. Because of that it is not possible to acknowledge (LEDs, Output Relays...) as
long as there are non-saved (cached only) parameters.
The acknowledgment menu cannot be accessed as long as the parameter modifications
are not taken over by the device (indicated by a star symbol in the upper left corner).
Existing passwords are persistent (assigned to a device). If an offline created parameter
file is transmitted into a device, or if a parameter file is transmitted from one device to
another, this will have no impact on existing passwords within the device.

Passwords – Areas
The access authorizations are designed in form of two hierarchic strands.
The supervisor (administrator) password provides access to all parameters and settings.
