Multi-Temperature-Controller KS 800
2 General
KS 800 is a microcomputer-based multi-loop temperature controller. Functions "set-point lowering"
and "heating/cooling with four alarms" make it ideally suited for temperature control of plastics 20
processing machinery, moulds, packaging machinery, tempering units and similar thermal proces-
ses. Furthermore, with high-power heating elements (e.g. in hot runner moulds), the selectable
functions "start-up circuit" and "output hold" in case of sensor break ensure increased element life
and prevent interruptions during production. The self-tuning feature guarantees very short start-up
times.

Multi-Temperature-Controller KS 800
2.1.1 Possible output configurations
Provided that other criteria are taken into account, the following controller configurations are
possible:
Signaller with one output
Signaller with two outputs
Two-point controller (heating switching)
Three-point controller (heating switching, cooling switching)
Three-point controller (heating continuous, cooling switching)
Three-point controller (heating switching, cooling continuous)
Three-point stepping controller (without position feedback)
Continuous controller
Split-range controller (heating and cooling continuous, 0...100% each; max. 4 controllers)
Three-point controller with watercooling (water vaporization)
Limitter with latch function
When configuring a controller output as a continuous output, the relevant switching output is firmly
assigned to 0% duty cycle.
With unused analog outputs, the output variable is 0V or 0mA.
3 Installation
3.1 Mounting
KS 800 is provided for fast clip-on mounting to "top hat" standard rails 35 x 7,5 to EN 50 022,
EN 50 035 and EN 50 045.
KS 800 earthing is via a spring to the "top hat" rail. Therefore, this rail must have a good, conduc-
ting connection with the grounded mounting wall (layer of lacquer, non-conducting mounting wall,
Eloxal, ...). If necessary, the "top hat" rail must be earthed using a separate connection.
Single unit: For mounting, pull the two latches on the sides upwards by approx. 5 mm via a click
point and snap on the unit to the mounting rail. Press these latches down to lock the unit in position
on the rail.
9499 040 49111 7

Multi-Temperature-Controller KS 800
Several units: For mounting several units side by side, snap on the first unit to the rail and lock
only the side on which no other unit shall be mounted. Snap on the second unit like the first one,
approx. 2 cm beside the first unit and shift it sideways to connect it to the first unit (locking pins
click into position). Press down the second latch of the first unit only now.
The connectors on the instrumentside (board-toboard connector; type: AMP champ-050-connection)
are used only for CANBUS through-connection, i.e. one CANbus connection is sufficient for several
units mounted side by side.
Bus connectors: These connectors are not used with the KS 800 Profibus and RS485 versions. In
this case, each unit must be connected to the bus separately via the 9-pin sub-D-connectors.
If the KS 800 units are operated together with other P-Open components in a CANbus system, the
KS 800 units must be connected as last instruments at the left or the right end of the modules side
by side on a rail. Otherwise, the individual component cannot be addressed. (The "addressing line"
is interrupted by KS 800.)
3.2 Dismounting
For dismounting, the leads need not be disconnected.
Before removing, mark the upper parts of the connectors and the corresponding lower parts, becau-
se the terminals are protected by design against distortion but not against wrong polarity.
For releasing the upper part of a terminal, press the two red ejectors in a terminal row towards the
circuit board by means of a screwdriver, if necessary.
For releasing the unit from the mounting rail, draw the two side latches (1) forwards by approx.
5mm (latch released) and remove the unit from the mounting rail by tipping it down or up.
For replacing an "inner" one of several units mounted side by side, start releasing the latch (and the
latch of the following unit!) at the end of the row and shift the unit sideways. Repeat this procedure
until reaching the unit which must be replaced. When its locking pins are free on both sides, the unit
can be tipped down or up out of the mounting rail.

4 Electrical connection
•Measurement and signal leads may carry max. 50 V rms against earth.
•Mains cables must be kept separate from signal and measurement cables.
•For protection of the outputs and avoiding interference, connected final elements must be
fitted with protective circuits according to manufacturer specification.

4.3 Galvanic isolations
The galvanic isolations of KS 800 are shown in the following diagram.
Identical block shading means that blocks are galvanically connected.
I.e. all outputs are galvanically connected, but isolated from inputs and microcontroller (controller).
All inputs are also galvanically connected.
An exception are the digital inputs/outputs, which are connected with controller outputs (and supply
voltage) independent of their configuration.
9499 040 49111 11

Multi-Temperature-Controller KS 800
4.4 Supply voltage
KS 800 is designed for a supply voltage rating of 24V DC, range 18V to 30V, residual ripple 5%.
The supply voltage must comply with the conditions of protective low voltage (SELV) according to
IEC 364-4-41 [VDE 0100-410].
Power supply load by one KS 800:
8 controller outputs + 4 alarm outputs each with 0,07A 20,16W
plus controller consumption 5,50W
results in a max. overall load (at 24V) of approx. 25,60W
The supply voltage minus pole is connected via the two external terminals (1 and 18) of
connector J1.
The plus pole is connected via terminals 19 and 36 of connector J2.
The supply voltage must always be connected from both sides, in order to prevent overload of
the circuit tracks.
We recommend using rail-mounted terminals with built-in fuse.
When mounting several units side by side, supply from one side and subsequent passing on
to the following unit must be avoided!
4.5 Fuses
Each unit must be protected with a separate fuse (in rail-mounted terminal) 2A, medium-fast.
Unless the "PWR" LED is lit with the supply voltage applied (check external fuse and polarity!), the
unit is defective and must be returned to the manufacturer.

Multi-Temperature-Controller KS 800
5 Inputs
(A complete KS 800 connecting diagram is given in section 7.)
Examples for connection are given in section 5.7.
The following rules are applicable to all analog inputs:
Unused analog inputs must be short-circuited!
Thermocouple and DC voltage:
Connect + and - terminal of each input.
Resistance thermometer:
Unused inputs for resistance thermometers must be configured as mV or ther
mocouple input. In this case, the + and - terminal of an input must also be
connected.
5.1 Analog inputs IN1...IN8
These analog inputs are the process value inputs of control loops1-8.These inputs can be confi-
gured for thermocouple, resistance thermometer or voltage. Within a controller, "mixed operation" of
inputs is possible.
5.1.1 Thermocouple inputs (IN1+/IN1- ... IN8+/IN8-)
The following thermocouple types according to DIN/EN 60584 can be connected:
Thermocouple
type Old description Ident. colour neg. wire Range
L Fe/CuNi blue 0... 900°C
J Fe/CuNi black 0... 900°C
K Ni-Cr/Ni green 0...1350°C
N Nicrosil/Nisil pink 0...1300°C
S Pt-10/Rh/Pt orange 0...1760°C
R Pt-13/Rh/Pt white 0...1760°C
T Cu/Cu-Ni brown 0... 400°C
W*) W5Re/W26Re not defined 0...2300°C
E Ni-Cr/Cu-Ni violett 0...1000°C
*)not according to DIN/EN
The upper KS 800 measuring limit is the upper limit for operation of the relevant thermocouple type.
The thermocouples are monitored for polarity error and break and the action (upscale/downscale) is
configurable.
All thermocouples must be connected with correct polarity at terminals INx+and INx-.
With thermocouples to DIN 43710, the plus arm is red and the colour of the minus arm corresponds
to the identifying colour of the thermocouple type.
According to DIN/IEC 584, the colour of the plus arm corresponds to the identifying colour of the
thermocouple type and the minus arm is white.
Terminals IPTx remain free.
9499 040 49111 13

Multi-Temperature-Controller KS 800
The controller inputs are not galvanically isolated. Therefore, measurement errors may occur with
thermocouple measurements above approx. 700°C and unsuitable thermocouples. This effect is due
to a decrease of the insulation value between protective tube and thermocouple to values of
a few kOhm from these temperatures dependent of construction type and insulation material.
Additionally, potential differences between the individual thermocouples due to hot gas ionization
may cause measurement errors or troubles due to compensating currents.
For the same reason, there may be problems when using grounded and isolated thermocouples in
mixed applications. The potential differences between thermocouples must not exceed 7Vss.
We urgently recommend avoiding mixed operation.
If using grounded and isolated thermocouples in an installation should be indispensable for
other reasons, the negative arm of the isolated thermocouple must be grounded at KS 800.
Already grounded thermocouples must not be grounded for a second time!
When replacing isolated thermocouples by non-isolated ones, removal of the negative arm
grounding at KS 800 is indispensable.
5.1.2 Cold-junction temperature compensation
There are four possibilities of temperature compensation:
1. The temperature compensation is ineffective (for PT 100 or mV inputs)
2. Internal temperature compensation. Compensating lead must be used up to KS 800.
3. External temperature compensation. Compensating lead must be used only up to the
cold-junction reference, leads between reference and KS 800 can be of copper.
4. Remote measurement of a cold-junction reference. Input IN8 can be configured so that it
functions as input of the temperature sensor of a remote cold-junction reference.
The thermocouples of each individual measuring point are connected to a common cold-
junction reference by means of compensating lead. The leads between cold-junction refe-
rence and KS 800 can be of copper. The 8th input is used for measuring the temperature of
this cold-junction reference and correcting the input voltage accordingly. For maintaining the
specified accuracy, the sensor should be a resistance thermometer. When using this tempe-
rature compensation method in an installation containing several KS 800 controllers, this
method must be used with each individual unit.
5.2 DC voltage (<100mV) IN1+/IN1- ... In8+/IN8-
DC voltages up to 100 mV instead of thermocouples can also be connected. Scaling of these valu-
es is possible via software adjustments.
The input resistance is approx. 100 kΩ.
14 9499 040 49111

Multi-Temperature-Controller KS 800
5.3 Resistance thermometer (IN1+/IN1-/IPT1 ... IN8+/IN8-/IPT8)
Pt 100, 2 or 3-wire connection
Resistance thermometer type PT 100 to DIN/IEC 751 can be connected in 2 or 3-wire circuit. The
max. measuring range is -100,0 ... 850,0°C, temperature-linear.
Connection in 3-wire circuit is possible without lead resistance adjustment, provided that the cross-
section of the individual wires is identical.
With 2-wire connection, a compensating resistor corresponding to the lead resistance must be fitted.
Using 2-wire connection is not recommendable.
The sensor is monitored for short circuit or break. The action (upscale/downscale) is configurable.
Resistance
wInstead of Pt10, a linearly variable resistor can be connected as a signal source in 3-wire circuit (
for connection, see section 7.1), 2-wire connection is not possible.
The max. resistance can be 400 Ω. The measuring range starts at 0Ωto the final resistance value
(max. 400Ω) The output action is reversible by connecting the wiper either to IN+ or IN- .
Monitoring is only for lead break.
5.4 Screening
For compliance with the regulations on electromagnetic compatibility to EN 50082-2, the connecting
cables must be screened. The 2 screening possibilities are:
1. Each input is provided with a grounded screen connecting terminal to which the cable
screening must be connected. These interconnected screenings must be connected to the
ground potential (protective earth) via terminal 108 by means of the shortest possible cable
(approx. 20 cm).
2. Use a commercially available screen connecting system.
5.5 Heating current measurement and heating current alarm
KS 800 has an input for connection of an external current transformer. All heating loads connected
to a controller module are taken through a current transformer. Further processing and evaluation of
the transformer signal are in the multi-controller module.
Measurement principle: a KS 800 "control cycle" takes approx. 600 ms for all 8 controllers. Heating
current monitoring for a controller is possible after each 4th cycle, i.e. at intervals of 2,25 s. Via
software, this interval can be increased by a factor between 0 and 99 in common for all controllers,
whereby 0 means no monitoring.
E.g. factor 10: heating current monitoring for controller 1 is done after 22,5 s. After another 22,5 s,
the heating current of controller 2 is monitored, etc., i.e. controller 1 is monitored again after 9 x
22,5 s = 202,5 s ≈3,5 min. Monitoring switch-off for individual controllers does not affect the cycle
time.
As all controllers except the one to be monitored are switched off during monitoring (which is swit-
ched on independently of its control status), the control accuracy can be affected negatively. There-
fore, heating current monitoring should be done only as frequently as necessary rather than as
frequently as possible.
9499 040 49111 15

Multi-Temperature-Controller KS 800
The current transformer input is not a measurement input in the sense of a calibrated measuring
instrument. The software for display calculation is designed for a single-phase 1000:1 current trans-
former (30A = 30mA). When applying other values to this input, there will be an error (3-phase
transformers, wave-form factor due to rectification and internal resistance outside KS 800...). Never-
theless, applying other variables to this input, e.g. 3-phase transformer with subsequent rectification
and totalizing is possible. In this case, scaling is not correct any more.
Therefore, the KS 800 current input must be matched to the relevant conditions:
Allow the current to be monitored of one heating loop to flow through the transformer. The relevant
controller measurement value is in a fixed ratio to the current, as long as the linearity limits are not
exceeded. E.g. the KS 800 display with 27A heating current is 19(A) (by additional external rectifi-
cation with a higher internal resistance). For monitoring a 10% current decrease, a limit of 17,1 (A)
must be adjusted.
However, the absolute measurement limits of transformer and KS 800 must not be exceeded:
1. The maximum current through the transformer(s). (When heating up the machine, all
heatings are switched on and the total of all heating currents flows through the
transformer(s). This current must be below the max. value permissible for this transformer,
otherwise, the transformer can be destroyed. For our transformers 9404 407 500x1, the
current limit is 100 A.
2. The maximum KS 800 input current must not exceed 100 mA (thermal limits).
3. Measurement is linear within 0 and approx. 35 mA.
When detecting an exceeded limit, this information is available at one of the alarm outputs or can
be read via the field bus.
Monitoring is done for exceeded min. and max. heating current limit.
Exceeded min. heating current limit: with the controller output switched off, an (adjustable)
heating current min. value is monitored, i.e. interruptions of the heating loop are detected.
Exceeded max. heating current limit: with the output switched off, monitoring is done for an
exceeded heating current limit of 3% of the heating current span (HC 100), which indicates leakage
currents.
The dyn. input resistance is approx. 170 Ω
Heating current monitoring is omitted, if a control loop is switched off.

5.6 Input circuit examples
5.7 Digital inputs
KS 800 contains 4 digital inputs, which can also be configured individually as inputs, unless requi-
red as controller outputs (cooling output with three-point controllers or closed output with three-point
stepping controllers).
The inputs are "high-active" and designed as current sink according to IEC 1131 type 1. The current
requirement is approx. 5 mA.
Logic "0" = -3...5 V
Logic "1" = 15...30 V
With configuration as input, the following allocation is applicable:
IN/OUT13: control parameter set 1/2 switch-over
This input is used to activate the 2nd control parameter set in common with all con-
trollers which are configured accordingly.
IN/OUT14: controller switch-off
This input is used for common switch-over of all controllers configured accordingly to
manual mode and for setting the outputs to "0". All other configured functions
continue operating normally.
See also hint on page 21.
IN/OUT15: Input for leakage current monitoring
The logic signal of an external leakage current monitor can be connected to this
input.
IN/OUT16: W/W2 switch-over
This input is used for activating the 2nd setpoint (W2) with all controllers configured
accordingly.
Unused digital inputs need not be connected.

Multi-Temperature-Controller KS 800
5.8 Input/output forcing
Unless connections IN/OUT13...IN/OUT16 or OUT17...OUT19 are used for their actual tasks, they
can be used as "free digital inputs/outputs" of a supervisory system. In this case, they cannot be
influenced by KS 800, but only as a system component via the system bus.
Inputs/outputs IN/OUT13...IN/OUT16 can be configured as digital inputs or outputs.
Alarm outputs OUT17...OUT19 can be used as digital outputs, whereby the electrical specifi-
cations of these inputs and outputs remain unchanged.

1) Outputs OUT1 to OUT8 are the "signal outputs".
2) Outputs OUT1 to OUT8 are the "signal outputs 1" and the outputs OUT9 to OUT16 are the
"signal outputs 2".
KS 800 has max. 19 outputs with identical specification:
Transistor outputs, + switching (for loads with common minus connection).
Rated output current:< 70 mA, short-circuit proof
Voltage drop with full load: typ. 0,3 V, max. 1,0 V
OUT1...OUT12 12 fixed logic outputs (controller outputs). The controllers and control-
ler output allocation are fixed. Reconfiguration is not possible.
IN/OUT13...IN/OUT16 4 variable inputs/outputs. They can be configured as controller outputs
(logic outputs) or digital inputs.

Multi-Temperature-Controller KS 800
OUT17...OUT19 3 outputs for alarms. The alarm allocation to the three outputs is confi-
gurable.
Unused outputs cannot be switched off individually. These outputs go to the status which is defined
in the KS 800 configuration. The inputs of these unused controllers must be short-circuited (see
also section 5).
Because of the variety of KS 800 configurations, note that:
The KS 800 options can be limited by the controller configuration.
With KS 800 configuration as two-point controller, all unused inputs/outputs are available for the
option.
With KS 800 configured as three-point controller (heating/cooling) or as three-point stepping control-
ler, 16 output are required with eight control loops, i.e. several options are not possible.
6.2 Controller outputs, continuous
The continuous controller terminals are accessible from the bottom through a cut-out in the
aluminium profile. Two 8-pin connectors must be used for connection.
The type of continuous outputs (voltage or current) is dependent of the KS 800 type (see section
2.1 Versions) and cannot be changed.
The current output, dead-zero (0mA) or live-zero (4mA), is adjustable via software.
Current output

tection up to ----1) short circuit proof
1) With low load resistances, the most important part of the power is converted (into heat) in KS800
itself, which implies a risk of instrument overheating, especially with high ambient temperatures.
With all eight controllers configured as current outputs, the load resistances should not be lower
than 250 Ω.
6.2.1 Analog output allocation
There are 2 modes of analog output allocation to the hardware outputs:
1. Up to instrument number 8396 (Dec. 2001) operating version 4:
Continuous outputs cannot be allocated firmly to the controllers and thus to the terminals. The order
of allocation is as with controller configuration with analog outputs.
