1. Your K 100
Is an instrument by Dr. A. Kuntze GmbH which offers high quality and reliability for
years.
It is one of our economy series K 100 with which we are trying to meet the rising
demand for low cost / high end instrumentation.
The K 100 instruments are defined by an excellent value for money. They were
developped to maximize functionability on standard applications. Nevertheless, the
K100 offers a variety of adjustments to obtain highest accuracy.
Select from a variety of measuring ranges from ks/cm to s/cm. The lowest measuring
range can alternatively be displayed in M /cm. In addition to temperature
compensation, less obvious influences such as cable capacitance or deviations
caused by cell dimensions or ageing effects can be compensated.
All K 100 instruments have an integrated controller which provides bidirectional PI
control, via two relays or as a steady-state controller via the analog output. You can
define a turn-on delay to prevent incorrect dosage after power failure and operate the
controller by remote control. Connect a level sensor, and the fail-safe will shut down
the controller automatically in a low water situation. Activate the dosage check function
to get an alarm if dosage achieves no results, indicating damages in the feeding lines.
New: Now you can configure the alarm relay as NO or NC, so that power failure gives
an alarm, too, and as pulse contact instead of permanent contact, to fit all kinds of
subsequent security systems. Furthermroe, input errors and low water are now
indicated via anlog output in addition to the relay/display indication.
Let´s not forget the alarm function with minimum and maximum limit and turn-on
delay...
You have certainly made a good choice. On the following pages you learn more about
your K 100. If, however, you have further questions or are looking for information not
included in this manual or if you are interested in supplementing products like
sensors or flow cells or in our other instrument series, just give us a call - we will be
delighted to help you!

1.1 General andsafety instructions

K 100 CM/IL & K 100 W CM/IL

1.2 Application
The instruments K 100 (W) CM and K 100 (W) IL are used to measure the electrolytic
conductivity in water and aequous solutions. K 100 (W) CM instruments work with
conductive sensors, K 100 (W) IL instruments work with inductive sensors. All have an
integrated controller with two set points. With this you can control actuators such as
dosing pumps or valves to add chemicals or fresh water until the desired conductivity
is reached and maintained.
Applications are washing processes, surveillance of ion exchangers, desalination of
cooling water, and concentration measurements for acidic or caustic solutions.
While the controller is set to Automatic, it controls independently the dosing of possibly
hazardous chemicals, according to the measured values.
For safety measures, the measuring inputs are checked for failure. Failures are
indicated in the display and via the alarm relay, which can set off a horn or lamp or
relate to a central control. If that failure makes control unreliable, the controller is
automatically switched off until the failure has been taken care off.
CAUTION The instrument checks the input signals and the water flow, if a flow
sensor is connected. It cannot detect erroneous settings or failures in
the treatment system, nor can it checkfor plausibility! The safety of
the systemof which the instrumentis part of, lies within the reach of
responsibility of whoever built thesystem.
1.3 Intended use
Use these instruments only for the monitoring and control of water.
Use only sensors, fittings, and accessories of Dr. A. Kuntze, since instruments and
sensors are attuned.
Ensure that the required measuring conditions are constantly maintained, such as
flow, pressure, temperature, etc.
Set-up the instrument according to this manual. Carry out all the steps described, and
check all measurements and settings before you activate the controller.
Use all available safety measures such as the alarm relay, the dosage check, and the
low water indication.
Regularly check that all safety measures are in good working order.
CAUTION The protection built into the instrument is impaired if they arenot used
asintended!

2.Instructionsfor installation andconnections
2. Instructions for installation and
connections
Installation:
On the next pages you will find detailed instructions for the installation.
For panel-type meters you have to prepare an opening of 92x92mm. Install the
instrument and fix it with the two mounting clips which were part of the delivery.
You can install instruments in wall-mounting housings either by hanging them upon
the center slot or by sliding the slot under a screw, which is an alternative for limited
space. Either way you have to fix it additionally with two screws.
ATTENTION Install the instrument in a place whereit is not put under mechanical
or chemical strain!
Mind the protection class:
K 100: Front IP54
K 100 W: IP65 (closed terminal cover)
Connections:
You will find detailed connection diagrams on the following pages.
Before connecting the power supply check the information on the instrument label!
ATTENTION Input, output and control lines must beinstalled separate from each
other and separate from power lines!
For inputs and outputs use screened lines and connect the screen on one side only.
The measurements are interference-sensitive. Always use the special sreened cables
delivered with the sensors.
For the connection of temperature sensors use a low-resistance cable with a large
diameter.
When using the relays, mind that with inductive loads, interference must be
suppressed. If that is not possible, the relay must be protected at the terminal block in
the K 100 by a resistance-capacitance filter or, in case of direct current, by a free-
wheeling diode.

3.1Howtoadjust parameters
3.1 How to adjust parameters
1) When you adress a parameter the actual setting is
displayed.
2) Switch to the next alternative setting with key .
3) When you have come to the last alternative, pressing the
key once more will bring you back to the start.
Selection between alternatives
For many parameters you have the choice between two or more alternatives, e. g.
between manual and automatic temperature compensation. For these parameters you
need only key . Switch from one alternative to the next until you either come back to
where you started or until you reach the alternative you were looking for.
With these parameters any changes are immediately valid - there is no need to store
the change.
1) Adress the parameter with key .
2) A double triangle appears behind the number indicating
that the number can be changed now with keys and .
3) Store the new value with key . The double triangle
disappears - the new value is stored.
Adjustment of numerical parameters
Numerical parameters can only be altered when a double triangle is visible behind the
number. This double triangle appears when you adress the parameter with key .
Adjust the parameter with keys and . A short pressure on the key changes the last
decimal by 1. If you keep the key pressed, the value will continue changing until the
pressure is released.
Store the changes with key . The double triangle disappears.
NOTE If you do not want to store the change, press key „M“instead of
key .
