In many applications, the measured parameters are used for control purposes. Neon

instruments can
be equipped with a controller with two set points. With this you can control actuators such as dosing
pumps or valves to add chemicals until the desired set point is reached. Alternatively, the measured
signal can be used as input for an external controller via the instruments´ interfaces.
Applications are for example neutralisation, detoxication, drinking water treatment, industrial waste
water, process water, disinfection, and process control.
As a safety precaution, measurement and calibration are checked for failure by the instrument. Failures
are indicated on the display via text messages that are stored in an eventlog and via the alarm relay
and, if activated, as 22mA current via the analog output.
If the failure makes control unreliable, the controller is automatically switched off until the failure has
been taken care of.
Warning
The instrument checks the input signals, 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!

Intended use
Use these instruments only for the monitoring and control of water – or, in case of gas monitoring
instruments, of ambient air.
Use only sensors, assemblies, and accessories made by Dr. A. Kuntze, and make sure that they fit your
application. Make sure that the required measuring conditions such as flow, pressure, temperature etc.
are constantly maintained.
Install and operate the instrument according to this manual. Carry out all steps described, and check
all measurements and settings before you activate the controller.
