5.1 Authorization levels
For the instrument configuration parameters setup, various authorization levels have
been planned, so as to prevent any changes to the instrument functions by non-
authorized personnel. Each parameter is associated with an authorization level, which
can differ from that of other parameters.
The following authorization levels have been provided:
Level 0: operator level.
Level 1: administrator level.
Level 0 parameters are not protected and can be displayed and changed by every
operator.
Level 1 parameters are protected by an access code. To view and change the
parameters, the user needs an access code.
The default level is 1.
For level 1 parameters, the default value for the access code is 000000, that can be
changed by the user via serial connection, if necessary, with the help of DeltaLog14
If the access code is changed, make sure to keep the new code in a safe
place. There are no commands for the “reset” of the access code. The loss of
the code precludes the possibility to change the configuration parameters set
to authorisation level 1.
In case of loss of the access code, the user shall address the technical service giving
them a number supplied by the instrument, through which it will be possible to
trace the code in the transmitter memory.
The number to be communicated is obtained via serial connection, by means of
DeltaLog14 application program or through the command PW of the communication
protocol (see section “COMMUNICATION PROTOCOL”).
In models with keyboard, the number to be communicated can be obtained following
the steps below:
1. Press MENU for at least 2 seconds, until the message “Press MENU to edit
parameters” appears on the display.
2. Using “
▼
” and “
▲
” keys, enter any number as first digit of the access code and
confirm with MENU.
3. Press MENU five times without entering any digits.
4. Take note of the number that will appear on the display and call the technical
service.
