DESCRIPTION
Front interface and Engineering Tools
Control parameter adjustment in
seconds has now also been
implemented in the KS 40 class of
instruments. Via the BlueControl
software incl. its simulation functions,
and especially the convenient BluePort®
front panel interface, the required set-up
for a specific control task can be
determined without a detailed study of
the operating instructions.
Off cause almost all adjustments can be
done comfortably over the instrument
front. (see page 6, BlueControl)
Limit values
The measured signal can be scaled
freely and monitored for limit values and
sensor break. Process status signalling is
possible by two
relays and six LEDs in
total. Moreover, an alarm or the
displayed value can be output as a
0/4...20 mA or 0/2...10 V signal via an
analog output.
Alarm hold function
Alarm statuses can be configured so that
they remain unchanged until
acknowledgement.
Controller
Apart from application as an indicator,
Digital 280-1 can be used as a signaller
or on/off controller, as a two-point or a
continuous controller.
Oxygen measurement:
When using a heated lambda probe, the
oxygen concentration can be displayed,
controlled and output directly as a
standard signal.
Range with O2 measurement:
0,0001% (1ppm) to 100.00%
Indication of values below 1 ppm is
possible via the voltage value display.
Linearization with 15 segments
Non-linear signals, e.g. filling quantities,
flows, etc. can be adapted by means of
user-specific linearization.
Plug-in module
As a plug-in module, Digital 280-1 can be
replaced very quickly without tools and
without impairing the wiring.
Password protection
If required, access to the various
operating levels can be protected with a
password.
