DESCRIPTION
The universal temperature controller
KS 4X-1 are intended for universal,
precise, and cost-effective control
tasks in all branches of industry. For
this, the unit provides simple 2-point
(on/off) control, continuous PID control,
or 3-point stepping control. The
process value signal is connected via a
universal input. A supplementary analog
input can be used for heating current
measurement or as an external
set-point input.
Every KS 4X-1 has three process outputs
that can be 3 relays or 2 relays
plus a universal output. This universal
output can be used for operating a solid-
state relay, a continuous current/
voltage output or to energize a
two-wire transmitter.
Plug-in module
KS 4X-1 controllers are built as plug-in
modules. This enables them to be replaced
very quickly without tools, and
without disturbing the wiring.
Self-tuning
During start-up, the self-tuning function
determines the optimum settings
for fast line-out without overshoot.
With three-point controller configuration,
the „cooling“ parameters are determined
separately, thus ensuring an
optimum match to the process.
Display and operation
Clear informations are given by ten indicator
LED’s in the front panel that
display operating mode, I/O states,
and errors. The auto/manual key switches
the controller into the manual
mode directly, without lengthy operating
sequences. If required, the direct
switch over can be disabled or the key
can be configured e.g. to start the internal
timer. This results in a level of
operational safety that is usually found
only in controllers of a higher price category.
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 7, BlueControl)
Password protection
If required, access to the various operating
levels can be protected with a
password. Similarly, access to a complete
level can be blocked.
