Device Functions Proline Promass 80 9 Group CURRENT OUTPUT 1/2
Endress+Hauser 27
TIME CONSTANT Use this function to enter a time constant defining how the current output signal reacts to
severely fluctuating measured variables, either very quickly (enter a low time constant) or
with damping (enter a high time constant).
User input:
Fixed-point number 0.01...100.00 s
Factory setting:
1.00 s
FAILSAFE MODE For safety reasons it is advisable to ensure that the current output assumes a predefined
state in the event of a fault. The setting you select here affects only the current output. It
has no effect on other outputs and the display (e.g. totalizers).
Options:
MIN. CURRENT VALUE
The current output adopts the value of the lower signal on alarm level (as defined in the
function CURRENT SPAN.
MAX. CURRENT VALUE
The current output adopts the value of the upper signal on alarm level (as defined in the
function CURRENT SPAN.
HOLD VALUE (not recommended)
Measuring value output is based on the last measuring value saved before the error
occurred .
ACTUAL VALUE
Measured value output is based on the current flow measurement.
The fault is ignored.
Factory setting:
MIN. CURRENT VALUE
ACTUAL CURRENT Use this function to view the computed value of the output current.
Display:
0.00...25.00 mA
SIMULATION CURRENT Use this function to activate simulation of the current output.
Options:
OFF
ON
Factory setting:
OFF
! Note!
• The “SIMULATION CURRENT OUTPUT” message indicates that simulation is active.
• The measuring device continues to measure while simulation is in progress, i.e. the
current measured values are output correctly via the other outputs.
" Caution!
The setting is not saved if the power supply fails.
