In/Outputs
(Continued)
In the "In/Output" submenu, you can configure the analogue current outputs, the
digital inputs, the alarm relays (only with the extension module) and the the
fieldbus module (if installed).
The current output itself is continually monitored and reports malfunction via a
redundant current path at a constant current of 24 mA.
7.3.1 Analog IO
You have the following setting options:
4 mA Output value (e.g. fill level) at 4 mA
20 mA Output value (e.g. fill level) at 20 mA
Error mode The error mode defines the behaviour of the error
relays in the event of an error.
Calibration of the Current
Output/Current Outputs If you find any discrepancies between the setpoint
and the actual value of the current signal, then you
can calibrate the current output again.
Note
In order to calibrate the current outputs, you will need an ammeter
(not included in the delivery contents), which is to be connected to
the relevant current output.
Note
BERTHOLD TECHNOLOGIES recommends calibrating the current out-
puts whenever a module has been installed/replaced or if a software
update has been carried out.
