Safety concept of the parameterization

The following tools are permitted for parameterization of the safety
function:
•
The integrated display and adjustment unit for on-site adjustment
•
The DTM suitable for the signal conditioning instrument in con-
junction with an adjustment software according to the FDT/DTM
standard, e. g. PACTware
Note:
To operate BMD 1L, the DTM Collection version 1.67.2 or higher is re-
with active connection to the instrument (online mode).
To avoid possible errors during parameterisation in a non-safe operat-
detection of parameter adjustment errors. The safety-relevant pa-
normal operating condition, the instrument is also protected (locked)
against inadvertent or unauthorized parameter changes. This concept
applies to adjustment directly on the instrument as well as adjustment
with PACTware and DTM.
To prevent unintentional or unauthorized adjustment, the set param-
eters must be protected from unauthorized access. For this reason
the instrument is shipped in locked condition. The PIN in delivery
status is "0000".
are accompanied by a list with the values deviating from the basic
setting.
The parameter settings of the measurement loop must be document-
status in chapter "Setup with the display and adjustment module"
under "Additional adjustments - Reset". In addition, a list of the safety-
relevant parameters can be stored and printed via PACTware/DTM.
For each parameter change, the instrument must be unlocked via a
PIN (see chapter "Setup steps - Lock adjustment"). The device status
is indicated by the symbol of an unlocked or locked padlock.
In delivery status, the PIN is 0000.
Warning:
If adjustment is enabled, the safety function must be considered
as unreliable. This applies until the parameterisation is terminated
correctly. If necessary, other measures must be taken to maintain the
safety function.
