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: For standard
electrodes no adjustments are required. The calibration solutions are automatically
recognised, regardless of the order in which they are used. After every single
calibration step the calibration curve is recalculated, so you can work with a 1-point
calibration, if you like.
For any non-standard application you can alter all parameters connected with
calibration: for restricted or outlying measuring ranges you can adjust the calibration
solutions as well as the zero-point of your measurement which is defined by the inner
buffer of the electrode.
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.
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 and Safety instructions
This manual applies to the following instruments:
Instrument and type Revision date
K 100 PR 01/08
K 100 W PR 01/08
It contains technical information for the installation, start-up and maintenance. If you
have any questions not included in this manual please contact your supplier or the
official representative of Dr. A. Kuntze GmbH in your country.
We would like to point out that the warranties specified in our general trading
conditions are valid only if
- installation, connections, adjustments, start-up, and maintenance of the
instrument are carried out by authorized personnel with adequate qualification.
- the instrument is used according to the description in this manual.
Please check for damages immediately after receiving the instruments and report any
damages within 24 hours to the delivering company. Never work with a damaged
instrument.
Keep this manual at a safe place where you can always look up the safety instructions
and the informations on handling and usage. According to DIN 61010 the manual is
part of the product and must be maintained as long as the instrument is used, and
given to the next owner if the instrument is sold.
This instrument was designed and built according to the safety measurements for
electronic devices and has left our company in perfect working condition. To preserve
this condition and to ensure safe usage follow all instructions carefully and pay special
attention to all warnings issued in this manual. If the instrument is visibly damaged or
has been stored inappropriately or if there are any doubts concerning safe usage, shut
it down and make sure it cannot be restarted by accident.
You will notice that important safety instructions are highlighted:
WARNING highlights instructions for the protection of people. Disregarding these
instructions may cause accidents and injuries!
ATTENTION higlights instructions for the protection of the instrument and the
equipment. Disregarding these instructions may lead to damage or
destruction of the instrument or equipment!
NOTE is used to highlight interesting details.

1.2 Application
The instruments K 100 PR and K 100 W PR can be used to measure and control the
pH or ORP value of water. Both 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 pH or ORP value 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 fit for your application.
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 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 measurements are interference-sensitive. Special screened cables with a very
high insulation over short distances, and an impedance converter for longer
connections.
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.
