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.
Operation requirements are reduced to an absolute minimum: The instrument is
delivered ready-to-use with a pre-adjusted working potential suitable for your
measurement. It is even pre-calibrated, so you will receive approximate measured
values immediately after installation. Single-point calibration is used to determine the
electrode´s response characteristic.
K 100 instruments are now optionally available with Automatic Cleaning function ASR.
The patent-pending electrochemical cleaning function prevents coatings of lime, rust,
or grease, and drastically reduces maintenance requirements.
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!

1.2 Application
The instruments K 100 Cl2 and K 100 W Cl2 can be used to measure the
concentration of free Chlorine in water. The other instruments measure the
concentrations of their specific parameters. Alle have an integrated controller with two
set points. With this you can control actuators such as dosing pumps or valves to add
chemicals until the desired concentration is reached and maintained.
Applications are detoxication of industrial waste water, water treatment, and
desinfection.
While the controller is set to Automatic, it controls independently the dosing of possibly
hazardous chemicals, according to the measured values.
For safety measures, both the measurement and the calibration 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, the calibration results, and
the water flow, if a flow sensor is connected. It cannot detect
erroneous settings or failures in the treatment system, nor can it
check for plausibility! The safety of the system of which the
instrument is part of, lies within the reach of responsibility of whoever
built the system.
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
lack-of-water indication.
Regularly check that all safety measures are in good working order.
CAUTION The protection built into the instrument is impaired if they are not used
as intended!

2.Instructions forinstallationand connections
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 where it 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 be installed 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 potentiostatic measurement is interference-sensitive, especially when using
membrane sensors. Use a special screened cable. Membran sensors are delivered
complete with cable.
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.

3.1How to adjustparameters
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

For the communication with the instrument you can choose from a variety of
languages.
Since choosing a language is part of the basic settings, it requires code 86. If a
different code is set, you will be asked to enter the correct password.

Potentiostatic measurements require a 1-point calibration:
Since the measurement depends upon the flow-rate and calibration solutions would
not be stable anyway, the sensor cannot be taken out of the armature for calibration, as
is done with pH sensors. Instead the actual concentration of the test water is
determined by an alternative method, for example photometrically with DPD, and this
value is entered as calibration value. Calibration of the Oxygen measurement is
simpler, using the Oxygen concentration of the ambient air.
The measurement is influenced by temperature. This influence can be compensated
manually or automatically. For manual compensation the temperature is entered
manually, for automatic compensation temperature has to be measured with a
temperature sensor. For the temperature compensation a linear coefficient can be
adjusted as %/K.
For smoother measured values activate the averaging function.
If you have purchased an instrument with Automatic Sensor Cleaning ASR, the basic
settings will include „cleaning“ where you can activate the automatic cleaning, define
the interval between subsequent cleaning cycles and the time for the first cleaning
cycle.
NOTE The menu „cleaning“ appears automatically when a sensor with ASR
is connected.
