1Introduction
Thank you for buying a KS 50-1 TCont.
This expert line unit offers special functions for tempering and hot-runner
equipment. An optional 20mA current loop or an RS485/422 interface are
available for easy connection of peripheral units including a KS 50-1 TCont to a
machine control system.
The protocol is widely used in the plastics industry and supported by many
injection moulder and extruder manufacturers, e.g. Arburg, Engel and
Krauss-Maffei. Another name for it is ”ARBURG protocol”.
This operating note describes the extended functions and features of
KS 50-1 TCont. For all other functions, refer to operating manual
9499-040-62811 for KS 50-1 Industrial Controller.
1.1 Definitions
A current loop interface transmits serial data by switching on and off a 20mA
current in a conductor loop at the data bit clock. During the rest condition, or
during transmission of ”1” bits, a constant 20 mA current is flowing, whilst the
current flow is intermittent with ”0” bits.
Another name for 20mA current loop interface is TTY interface
(TeleTYpe(writer)).
lCaution! The unit contains ESD-hazarded components.

3.2 Behaviour after power-on
After supply voltage switch-on, the unit starts with the remote mode and goes
then into the standby mode. The controller mode is switched off. (SP =OFF).
3.3 Functions for tempering units
KS 50-1 TCont has a lot of possibilities to connect signals coming from and
going to the tempering unit.
wThe process value is connected to INP1.
wAn output signal of a safety temperature limiter (STL) can be attached
alternatively to di1 to di3. When responding the STL the controller goes into
the switching off mode (stop). The signal is passed on in the protocol (see
page 18).
wThe operation of the controller can be accomplished in the remote or in local
operation. For the change-over the inputs di1 to di3 or the F-key are
available. In remote mode values can be given only over the attached
interface; inputs via the front are blocked. Vice versa in local mode set-point
operations over the interface are not permitted. As answer the device
supplies a NAK message.
wFor local starting and stopping of the tempering unit push-buttons or
switches can be selected and attached at the inputs di1 to di3. The function
start or stop is released with the change of 0 to 1, independently of the
configuration of di.Fn as push-button or switch.
wSelected signals for sensor mode, level alarm or flow alarm can be connected
to di1 to di3. They are only through-handed in the device, but indicated in
the protocol (see page 17).
wThe alarm for safety temperature - monitoring can be determined with limit 1
(Lim.1).
wKS 50-1 TCont supplies a continuous signal to control a pump, which can be
connected to OUT1 to OUT6.
wAfter a stop command the pump is only switched off, if the return flow
temperature is fallen below the adjusted limit, which is defined over the
set-point SP2.
gIf the inputs for start and stop are not wired, then the same functionality can be
achieved in local mode by switching on and off the controller function (for
switching off put the set-point SP to OFF; for switching on enter a valid
set-point). The start instruction corresponds to the control command (r) in the
remote mode, the stop command to the control command (p).

3.4 Functions for hot-runner
To operate with the protocol extension for hot-runners only a few additional
inputs and outputs are needed.
wThe operation of the automatic controller can be switched over from remote
to local operation. Therefore the inputs di1 to di3 or the F-key are available.
In local operation a start-/stop functionality can be achieved by switching on and
off the controller (for switching off put the set-point SP to OFF; for switching
on enter a valid set-point). The start command corresponds to the control
command (r) in the remote mode, the stop command to the control command (a).
