Functional description
TOTALIZER TOTALIZER  OPERATION
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
The current output adopts the value of the lower signal on alarm level (as defined in
the function CURRENT SPAN (4001)  ä 88
MAX. CURRENT
The current output adopts the value of the upper signal on alarm level (as defined in
the function CURRENT SPAN (4001)  ä 88
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
Use this function to configure the current output as "active" or "passive".
Options:
PASSIVE
The current loop is powered externally (ie. from the DCS).
ACTIVE
The current loop is powered from the Prosonic Flow 93T transmitter.
!
Note!
When using the current output in "ACTIVE" mode the battery life is reduced by
approximately 25%.
Factory setting
PASSIVE
Use this function to view the computed actual value of the output current.
User interface
0.00...25.00 mA
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 measuring values are output correctly via the other outputs.
"
Caution!
The setting is not saved if the power supply fails.
