1.Your Neon
is an instrument by Dr. A. Kuntze GmbH which offers high quality and long-term
reliability, made in Germany.
With its modular design, the Neon instrument can be tailored to your application.
The entry-level version contains inputs for measurement and temperature, a digital
input, and an alarm relay. You can choose between key pad or touch screen
operation.
A set of codes allows access to different operation levels. If you want to ensure that
only authorized personnel can operate the instrument, define an auto-lock time after
which the code is reset to default setting.
Save energy with the Eco mode, in which the display illumination is deactivated after
an adjustable interval.
The Neon instruments have an SD card slot. You can store and load instrument
settings, to duplicate software settings to additional instruments or to reinstall your
settings after updates or repair. You can also use the SD card for software updates.
We have equipped the Neon instruments with some very convenient features:
The touch screen for example is the perfect complement to the graphical operation
and gives you shortcut access to important menus from the main display.
The information displayed on the screen can be defined by the user, adding for
example control values, data log status, - or maintenance information, such as the
name and phone number of responsible facility personnel. In case of problems, the
diagnosis function allows quick assessment of the situation.
Test functions make trouble-shooting and installation easier by providing manual
operation of all digital and analog outputs.

The Neon instruments are expandable through software add-ons and hardware
modules. You can add:
A second digital input
Up to two analog outputs
A data log function that stores data on the SD card
A PID controller with two control relays for concentration-based dosing
Volume-based dosing with two relays and flow measurement
Modbus RTU interface
With the Neon you have certainly made the right choice. On the following pages find
out more about your instrument. If you have further questions or are looking for
information not included in this manual or if you are interested in supplementing
products such as sensors, or assemblies, just give us a call –we will be delighted to
help you!

1.1. General and safety instructions
This operation manual applies to the following instruments
Instrument type Neon pR
SW version V 2.03
The manual contains technical information on installation, operation, and
maintenance.
Keep this manual in a place where you can always look up the safety instructions
and the information on handling and usage. According to DIN 61010 the manual is
part of the product and has to be preserved as long as the instrument is used, and
given to the new owner if the instrument is sold.
The instrument was designed, built, and tested according to the directives for
electronic devices and has left our company in perfect working condition. To
preserve this condition and to ensure safe operation, 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 operation, shut it down and make sure it cannot be restarted.
You will notice that certain safety instructions are highlighted:
Warning highlights instructions for the protection of people. Disregarding
warnings may cause accidents and injuries!
Attention highlights instructions for the protection of the instrument and
equipment. Disregarding these instructions may lead to damage or
destruction of the instrument or equipment!
Note is used to highlight interesting details.

1.2. Warranty conditions
We have to point out that the warranties specified in our trading conditions are valid
only if the following conditions are met:
Installation and start-up by Dr. A. Kuntze personnel or trained and authorized
technicians
Maintenance of instrument and peripherical equipment according to the
instructions of this manual
Use according to the designation specified on the following pages
Use of original accessories and spare parts only
Observance of operation conditions and settings according to this manual
Warranty is void if any one of the conditions listed above is disregarded.
1.2.1 Transport damages
Please check for damages immediately after delivery and report any damages within
24h to the delivering company. Never work with a damaged instrument!
1.2.2 Application

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!

1.2.3 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.
Use all available safety measures such as the alarm relay, the 22mA alarm current,
the dosage control, and the low-water indication.
Regularly check that all safety measures are in good working condition!
Warning The protection built into the instrument is impaired if it is not used
as intended!

2.2. Installation panel-mounted housing
Prepare an opening of 138 x 138 mm. Clip the
installation frame into the opening.
Place the instrument inside the frame and secure
it with the M4 x 25 screws. Tighten the screws
until the instrument is firmly fixed.
Attention To preserve the protection class, the flat gasket of the housing
and the sealing ring of the frame must be used!

2.3. Installation wall-mounted housing
Pierce the pre-cut openings of the
housing for as many cable glands as
you wish to use and remove any
remaining pieces from the openings.
Place the installation plate into the back frame and screw in the cable
glands.
Drill two holes at 80 mm horizontal distance. Screw two screws into the
holes and mount the instrument on the screws.
Or you can open the instrument and put the screws through the holes at the
back of the instrument. Mind to replace the covers before closing the
instrument.

2.4. Connections
A detailed connection diagram can be found on the following pages.
Before connecting the power supply check the information on the instrument label!
Warning Input, output, and control cables must be installed separate from
each other and especially apart from power lines!
For inputs and outputs use screened cables, and connect the screens on one side
only.
The measurements are interference-sensitive. Use only our special cables with a
very high insulation for short distances, and for longer distances an impedance
converter.
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
by a resistance-capacity filter or, in case of direct current, by a free-wheeling diode.
