Measurement of free chlorine/chlorine dioxide/
total chlorine

Transmitter for chlorine sensors

Application• Drinking water• Water treatment• Cooling water• Gas scrubbers• Reverse osmosis• Food processing• Swimming pool waterYour benefits• Field or panel-mounted housing• Universal application• pH compensation for free chlorine• Simple handling– Logically arranged menu structure– Calibration via CAL button• Safe operation– Overvoltage (lightning) protection– Manual contact control and user-defined alarm configuration
The basic unit can be extended with:• 2 or 4 additional contacts for use as:– Limit contacts (also for temperature)– P(ID) controller for chlorine and pH– Timer for simple rinse processes– Complete cleaning with Chemoclean• Plus package:– Manual pH compensation for Cl2– Any current output configuration via table– Automatic cleaning start– Process monitoring and live check of sensor• HART or PROFIBUS PA / DP
• 2nd current output for temperature, main measured value or actuating variable• Current input for flow rate monitoring with controller shut off or for feedforward

Function and system design
Features of the basic version(EK)

Measurement of free chlorine, chlorine dioxide and total chlorine
The sensor is selected from the menu. The temperature is displayed but the reading can also be
hidden. The EP version has an alternative feature that allows simultaneous display of the pH and redox
measurements.
Calibration
The CCS140/141 sensors for free chlorine and the CCS240/241 sensors for chlorine dioxide are zerocurrent-free and therefore require only single-point calibration. This is carried out by entering a DPD
reference measured value.
The sensor CCS120 is also calibrated by entering a DPD reference measured value. Additionally you cancalibrate the zero point of the sensor CCS120 (recommended for measurements below 0.1 mg/l).
Configuration
Different alarms are required depending on application and operator. Therefore the transmitter
permits independent configuration of the alarm contact and error current for each individual error.
Unnecessary or undesirable alarms can be suppressed in this manner. Up to four contacts Up to two
contacts can be used as limit contacts (also for temperature), to implement a P(ID) controller or for
cleaning functions.
Direct manual operation of the contacts (bypassing the menu) provides quick access to limit, control
or cleaning contacts, permitting speedy correction of deviations.
The serial numbers of the instrument and modules and the order code can be called up on the display.

Additional functions of the
Plus package (ES)Current output configuration
In order to output wide measuring ranges while still achieving a high resolution in specific ranges, thecurrent output can be configured as required via a table. This permits bilinear or quasi-logarithmic
curves, etc.
Manual pH compensation for free chlorine
Measurement of free chlorine with amperometric sensors is pH-dependent while DPD measurement
used for calibration is pH-independent. Manual pH compensation means the instrument can also be
used to measure a variable pH value with a slow rate of change.
Process Check System (PCS)
It comprises two independent safety functions:• Errors in applications without control are detected by monitoring the limit beween plausible andimplausible measured values, i.e. the alarm threshold.
• Errors in applications with control are detected by the controller monitor which monitors freely
adjustable, maximum permissible time intervals and reference value overshoot or undershoot.
Live check
The live check issues an alarm when the sensor signal does not change over a defined period of time.
This may be caused by blocking, passivation, separation from the process, etc.

Additional functions ofversion EP

Alternatively measurement of pH or ORP

Second current output

The second current output is freely configurable for the output of temperature, of the main measured
value (free chlorine, chlorine dioxide, total chlorine) or actuating variable.

Current input

The current input of the transmitter allows two different applications: controller shut-down in case oflower flow rate violation or total failure in the main flow as well as feedforward control. Both functions
are also combinable.

2

This extension allows additional measurement of pH value or ORP in an instrument. It also allows
control of the pH value in the process.
Automatic pH compensation means the instrument can also be used to measure a variable pH value
which is subject to frequent changes.
