5.2.13 Level control
It can be selected whether the control system will run via the internal
level sensor (dynamic pressure, bubbler system), an external 4 -
20 mA level sensor or a float switch. The input for the high water
alarm (
terminal 19 / 20
) is always active and can be used as a
redundant system. When using external 4 - 20 mA level sensors and
float switches installed in an explosive area, it will be necessary to use
components with the requisite certifications.
5.2.14
20 mA => Level
This setting adapts the switch points and the display of the level to a
connected external 4 - 20 mA level sensor. The processor converts
the input signal such that the correct level is displayed. When the
measurement range for the 4 - 20 mA sensor is changed in the
configuration menu, the switch points will have to be re-configured,
as they will have changed determined by the system. Thus, the
correct order will always be to first configure the sensor’s
measurement range and then the switch points. The corresponding
regulations must be observed for the use in the EX zone, i.e. a 4 -
20 mA sensor with corresponding certification and a matching EX
barrier. If the switch points are outside the level sensor’s configured
range, then the message
“Check switching points”
will be shown.
5.2.15 Bar Level max. / Bar Current max.
In order to allow for a practical resolution of the bar graph display,
the maximum value of the respective display can be set here. If AUTO
is selected in the menu item, the maximum value of the respectively
set level or the max. current will be used automatically.
