Administrator PIN code
All functions and menus which may disturb the analyser’s normal measurement can be
protected against unauthorized access by activating the administrator PIN code
request.
We highly recommend activating this function, when unauthorized persons could
access the analyzer.
The PIN code is:
F1 - F1 - F3 - F2 - Up - Down
The PIN code request can be activated and deactivated in the menu Extras/General
settings:
The deactivation of the PIN code request requires at least one time PIN code input.
Once the user has input the correct administrator PIN code the analyser will stay in
administrator mode (password free) for 10min after last time key acting. Each key acting
will trigger another 10min password free operation.
11.2. Power-On of analyser
When the analyser is connected with mains (Power-On) it will start the system boot
process which usually takes very few seconds. Then the display will show the self-test
menu.
11.3. Self-Test
The first menu to be displayed after Power-On is the self-test menu. The analyser won't
leave this menu before all sub-systems will be connected and the gas cooler (option)
has reached the target operation temperature.
During the self-test phase
•
the gas pump is switched off
•
all analog outputs will deliver 2mA
•
all alarm outputs will have alarm status (open contacts)
Usually the self-test will be left automatically as soon as all conditions for measurement
are satisfied. Then the first zeroing will be started.
If one of the internal RS485 bus participants are issuing alarm (faulty) status, the user
can still leave the self-test manually by pressing F2='forward' (PIN code requested), even
if not all sub-systems or the gas cooler are ready.
NOTE: this is for service purpose only!
