4.3.1 Analysis and monitoring
The positioner generates the 'Supply pres-
sure status' message with the dened status
classication.
− 'Too high' if the supply pressure exceeds
the 'Upper limit'.
− 'Not available' if the supply pressure falls
below 0.1bar.
− 'Too low' if the supply pressure exceeds
the 'Lower limit'.
− 'Permissible limit exceeded' if the supply
pressure exceeds 7.0bar.
A uctuating supply pressure is recognized
by the positioner whenever the supply pres-
sure continuously falls below the 'Lower limit'
and rises above the 'Upper limit'. In such
cases, the positioner generates the 'Supply
pressure status' message with the dened
status classication.
