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!
