1.1 Safety-related characteristic values
In various applications, the operation of pressure or differential pressure transmitters at
overpressure (outside the measuring range, < MWP) or low pressure is not critical.
The state of the processes must be assessed and the various parameters must be taken into
consideration.
• Low pressure or overpressure not dangerous → message E727 pressure overrange =
Warning
• Low pressure or overpressure dangerous → message E727 pressure overrange = Alarm
Depending on the configuration profile selected for the messages, different parameters
must be considered when assessing the facility:
• Message E727 pressure overrange = Alarm → parameter profile A applies
• Message E727 pressure overrange = Warning → parameter profile B applies
Parameter profiles A and B depend on the alarm settings and not on the firmware version.
For firmware versions up to and including firmware version 02.20.04, message E727 was
set, as a rule, to "Alarm" for SIL locking with increased security during parameter entry.
With firmware version 02.30.zz and higher, the settings for message E727 remain
unchanged.
