2.2 Device description of the system
The system for measuring dissolved free chlorine, chlorine dioxide or ozone is a ready to use and
tested measuring system with integrated temperature sensor for compensation. As an option a
pH measurement can be added in a third flow-through cell. The Automatic Sensor Cleaning
(ASR, Patent Dr. A. Kuntze) is part of the standard device. All sensors have to be installed and
calibrated before use.

2.3 Device description of the sensor
The sensor for measuring free chlorine, chlorine dioxide or ozone is characterised by a robust
design and extremely low maintenance requirements. The sensor comprises double gold
electrodes and a low maintenance gel filling. The measurement is suitable for flow velocities
above 30 l per hour / 7.9 gal per hour. The optimum is a stable flow at 40 l per hour /10.5 gal per
hour.
The sensor is equipped with the patented Automatic Sensor Cleaning (ASR, Patent Dr. A.
Kuntze). An electrochemical process causes generation of oxygen and hydrogen directly on the
gold electrodes, dissolving even tough coatings such as lime deposits. Additionally oxygen
oxidizes organic compounds and hydrogen reduces rust and manganese oxide and likewise
destroys organic coatings. The ASR considerably increases the life span of the sensors,
achieving high measuring stability with extremely low maintenance requirements.
2.4 Nameplate
The system type is specified on the labelling of the measuring system package and on the
measuring system itself.

3.4 Installing the system
3.4.1 Mounting of the OPTISYS CL 1100 measuring system
The measuring system is delivered ready to use. It can be mounted in a distance of 20 mm / 0.79"
to a wall via 4 predrilled holes.
Water connection
Connect the water inlet on the left side and the outlet on the right side of the flow cell. The outlet
can be an open outlet (pressureless) or the water can be re-directed into a pipe or basin.
3.5 Examples of a typical measuring point
The following drawing show an example of a typical measuring point consisting of a sensor and
the flow-through assembly.
CAUTION!
Install the device at a place where mechanical and chemical stress is limited.
Mind the ingress protection: IP66/67 (acc. to NEMA 4/4X) with closed terminal cover
CAUTION!
The sensors are delivered with protective caps, which have to be removed before mounting into
the flow cell.

B2.5 ORP In this menu the potential of ORP can be simulated. For 2 channel version
only; refer to pH/ORP sensor manual for further information. ONLY if
switched to ORP.

This menu groups several functions which allow to display the corresponding actual reading. The shown measurements
are depending on the device configuration.

B4.3 process input B In this menu the measurements from process input B can be read.
For 2 channel version only; refer to pH/ORP sensor manual for further
information.
INFORMATION!
The signal converter has two process inputs, A and B. Each process input has an own submenu
in this main menu. Process input A is always present, i.e. there is always a board in the interface
"Pos.A" in the connection area. The interface of process input B only has a board with the two
channel signal converter. Be aware that the definition which kind of measurement a process
input can do is defined when ordering the device. The configuration cannot be changed later.
INFORMATION!
Note that the appearance of some submenus depends on the hardware setting and the used
sensor(s).
Level Designation / function Settings / descriptions
Process input A and B can be either a sensor 1 or a sensor 2. Further information about the type of sensor 1 or 2 please
refer to MAC 100 manual "Sensor input combinations". Process input A is always present, process Input B can be
present.
Note: The exchange of a sensors 1 with a sensor 2, or vice versa, can only be done by the manufacturer!
Depending on the sensor which is connected to a slot A or B the menu changes.
