Connecting the chlorine sensor 963
The chlorine sensor 963 is supplied without a temperature sensor ex factory. Connect the
chlorine sensor to the transmitter as follows:
• Without temperature measurement:
Connect the 10 kΩ equivalent resistor supplied to terminals 11 and 12. The measured
value display will then constantly show 25 °C (77 °F).
• With temperature measurement:
Mount an NTC temperature sensor 10 kΩ / 25 °C (77 °F) (120 mm installation version
TSP 3692) in the chlorine sensor 963. Use the CPK1 connecting able to connect the
temperature sensor to terminals 11 and 12.
• Chlorine sensor:
Connect the red cable to terminal 92 (cathode) and the blue cable to terminal 91
(anode).
Connection of pH or ORP sensors
Connect the pH or ORP sensor always symmetrically to prevent a mutual interference of
several sensors mounted in the CCA250 assembly.
Symmetrical connection requires a potential matching pin. The pin is integrated as
standard in the CCA250 flow assembly and is connected by a PML to the PA/PM terminal.

Flow monitoring in the sample stream
If the flow falls below 30 l/h or if sample flow through the CCA250 assembly fails
completely, this causes an alarm to be signaled when an INS proximity switch is connected.
This alarm becomes active when the switch-off delay time elapses (A4 field). The alarm is
canceled immediately as soon as the necessary rate of flow is restored. The device
automatically stops the dosing of chemicals and the Chemoclean cleaning function for the
duration of the alarm. All the relays assigned to the PID controller or to a cleaning function
go to the quiescent state. The NO contact closes in the case of the three-point step
controller. Dosing and cleaning actions are only resumed once the switch-on delay time
has elapsed (A5 field).

Types of chlorine
A distinction is made between free chlorine and combined chlorine.
Free chlorine
44
Endress+Hauser
Liquisys M CCM223/253
Commissioning
Free chlorine is understood as the sum of elementary chlorine (Cl2), hypochlorous acid
(HOCl) and hypochlorite ions (OCl–). These forms of chlorine are able to kill bacteria,
inactivate viruses and oxidize organic substances within a short period of time.
Combined chlorine
Combined chlorine refers to the forms of chlorine in water and consists of chemical
compounds made up of chlorine and ammonia (NH3) or ammonium (NH4 +) entstehen.
Combined chlorine still has a disinfectant property, but far less than that of free chlorine.
Total chlorine
Total chlorine is the sum of free chlorine and combined chlorine.
Measuring free chlorine with the CCS140 and CCS141 sensors
Molecular chlorine (Cl2) is present at pH values < 4. Consequently, hypochlorous acid
(HOCl) and hypochlorite (OCl– remain as components of free chlorine within the range of
pH 4 to 11.
As hypochlorous acid splits up (dissociates) with an increasing pH value to form
hypochlorite ions (OCl–) and hydrogen ions (H+), the amounts of the individual
components of free effective chlorine change with the pH value. For example, if the
amount of hypochlorous acid is 97% at pH 6, it drops to approx. 3% at pH 9.

pH compensation
The CCS140 or CCS141 chlorine sensors selectively measure the amount of hypochlorous
acid in amperometric measurement.. This works as a powerful disinfectant in a watery
solution. In contrast to this, hypochlorite is an extremely weak disinfectant. Therefore,
when used as a disinfectant at higher pH values, the effectiveness of chlorine is limited. As
hypochlorite ions cannot permeate the sensor membrane, the sensors do not record this
value.
Measuring total chlorine with the CCS120 sensor
If, in addition to free available chlorine, ammonium is also present in the medium preferably water - chloramines (ClnNHm) form quickly. This compound is formed in various

degrees of dimerization. It is known as "combined chlorine". Combined chlorine has a lower
disinfecting effect but it forms larger depots compared to free chlorine. This means:
• Significantly slower elimination of existing germs.
• Disinfectant effect over considerably longer periods.
• Disinfectant effect over considerably longer transport distances.
The CCS120 amperometric sensor measures the total chlorine content, i.e. free chlorine as
well as chloramine components.
This type of measurement is only slightly pH dependent.
pH compensation of the chlorine sensor signal during free chlorine measurement
(only for ES and EP versions, for CCS140/141 sensors)
To calibrate and verify the chlorine measuring system, a colorimetric reference
measurement must be carried out using the DPD method. Free chlorine reacts with
diethyl-p-phenylendiamine to form a red dye. The intensity of the red color increases
proportionally to the chlorine content. With the DPD method, the water under
measurement is constantly buffered to a pH value of approx. 6.3. Therefore, the pH value
of the water under measurement is not included in the DPD measurement here. Due to the
buffer function in the DPD method, all components of free effective chlorine are recorded
and thus the total free chlorine is measured.
If you select pH compensation in fields B2 or B3, the sum of hypochlorous acid and
hypochlorite corresponding to the DPD measurement is calculated from the hypochlorous
acid measured by the sensor and the pH value in the region of pH 4 to 9. For this
calculation, the curve is stored in the transmitter.
When free chlorine is measured with pH compensation switched on, always perform
calibration in pH-compensated mode.
When you use pH compensation, the measured chlorine value that is displayed and applied
to the device output corresponds to the DPD measured value even if the pH values
fluctuate. If you do not use pH compensation, the measured chlorine value corresponds to
the DPD measurement only if the pH value remains unchanged compared with the
calibration. Without pH compensation, the chlorine measuring system must be
recalibrated when the pH value changes.
pH compensation can be performed both automatically using the connected pH electrode
(EP version) and manually (ES version) by entering the pH value in the B3 field.
Chlorine dioxide and total chlorine measurement is largely or entirely independent of the
pH value and therefore no pH compensation is required.
Accuracy of pH compensation when measuring free chlorine
The accuracy of the pH-compensated measured chlorine value is derived from the sum of
several individual deviations (chlorine, pH, temperature, DPD measurement etc.).
High levels of hypochlorous acid (HOCl) during chlorine calibration have a positive effect
on accuracy, whereas low levels of hypochlorous acid have a negative effect.
The inaccuracy of the pH-compensated measured chlorine value increases the greater the
pH difference between measuring mode and chlorine calibration or the more inaccurate
the underlying individual measured values are.
Calibration of free chlorine taking the pH value into consideration
The reference measurement (DPD method, photometer) determines the total free chlorine
by buffering to pH 6.2. In contrast to this, amperometric measurement determines only
the HOCl component.
During operation, pH compensation is effective up to a pH value of 9. However, there is
hardly any HOCl left at this pH value, and the measured current is very low. At this point,
pH compensation has the effect of increasing the measured HOCl value to the actual value
of the free chlorine.

Current input
For the "Current input" function group, you require a relay card with a current input which
is not available in the basic device version. With this function group, you can monitor
process parameters and use them for feedforward control. For this purpose, you must
connect the current output of an external measured variable (e.g. flowmeter) to the 4 to
20mA input of the transmitter. The following assignment applies:

Flow monitoring in the main stream
This arrangement is particularly practical if the sample flow through the CCA250 assembly
is completely independent of the flow in the main stream.
This permits signaling of an alarm condition in the main stream (flow too low or has
completely stopped) and triggers dosing switch-off even if the medium flow is maintained
due to the method of installation.
This monitoring method corresponds to monitoring the flow rate in the sample stream
(see SETUP 1).

Check
The CHECK function group is only available for devices with the Plus Package (ES and EP
versions).
In the CHECK function group, you can select different monitoring functions for the
measurement.
By default all monitoring functions are switched off. The Sensor Check System is adapted
to the current application conditions by adding and setting the suitable functions.
Alarm threshold monitoring
When you perform chlorine or chlorine dioxide measurements without chemical dosage
control, sensor errors lead to a measured value error, but have no impact on the process
medium (examples: monitoring measurements in water works). Sensor errors generally
cause implausibly high or low readings. This is detected and signaled by user-definable
alarm thresholds.
Controller monitoring
When you perform chlorine or chlorine dioxide measurements with simultaneous chemical
dosage control, sensor errors not only result in incorrect measured values but also directly
impact the state of the process medium.
Particularly in the case of regulated water disinfection, due to the closed control loop there
is the risk that chemical dosing will not switch on if the measured value is constantly too
high. This poses a considerable danger to process stability, and could even pose a serious
health hazard for humans. On the other hand, if the measured value is constantly too low
this results in higher operating costs and a risk of corrosion due to the continuous dosing
of chemicals.
These cases are detected and signaled using user-definable monitoring times for
maximum permitted limit value overshoot and undershoot.
Sensor activity monitoring
The effect of the process medium on the sensor can also result in incorrect measured
values. For example, severe deposit buildup on the sensor membrane can cause the

Relay configuration
For the "RELAY" function group, you require a relay card which is not available in the basic
device version.
The following relay contacts can be selected and configured as desired (max. four contacts,
depending on options installed):
• Limit contactor for chlorine/chlorine dioxide measured value: R2 (1)
• Limit contactor for pH/ORP measured value: R2 (2)
• Limit contactor for temperature: R2 (3)
• PID controller for chlorine/chlorine dioxide: R2 (4)
• PID controller for pH: R2 (5)
• Timer for cleaning function: R2 (6)
• Chemoclean function: R2 (7)
• Three-point step controller for chlorine/chlorine dioxide: R2 (8)
Only one function can be assigned to each relay. If a relay function is already switched on
(R211 to R281), it is switched off automatically when you select another function and
press ENTER to confirm (R2(1) to R2(8)).
Pressing the REL key allows you to display the corresponding setpoint of every relay
function.

Limit contactors for chlorine/chlorine dioxide/total chlorine measured value and
temperature or pH or ORP measured value
The transmitter has different ways of assigning a relay contact. Switch-on and switch-off
points and pickup and dropout delays can be assigned to the limit contactor. In addition,
you can configure an alarm threshold to output an error message and to start a cleaning
function in conjunction with this.
These functions can be used both for the primary value and for temperature measurement.
Please refer to the switch states in → 36 for a clear illustration of the relay contact
states.
• When the measured values increase (maximum function), the relay contact is closed as
of t2 after the switch-on point (t1) has been exceeded and the pickup delay has elapsed
(t2-t1).
The alarm contact switches if the alarm threshold (t3) is reached and the alarm delay
(t4-t3) has also elapsed (errors E067 to E070).
• When the measured values decrease, the alarm contact is reset when the value falls
below the alarm threshold (t5) again, as is the relay contact (t7) after the dropout delay
(t7-t6).
• If the pickup and dropout delays are set to 0 s, the switch-on and switch-off points are
also switch points of the contacts.
The same settings can also be made for a minimum function in the same way as for the
maximum function.

P(ID) controller
You can define various controller functions for the transmitter. On the basis of the PID
controller, P, PI, PD and PID controllers can be implemented. For an optimum control
system, use the controller that best suits your application.
• P controller
Used for simple linear control purposes with small system deviations. Where major
changes are to be controlled, overshooting may occur. In addition, a lasting control
deviation must be expected.
• PI controller
Is used for control systems where overshooting is to be avoided and no lasting control
deviation should occur.
• PD controller
Is used for processes that require quick changes and where peaks must be corrected.
• PID controller
Is used for processes where a P, PI or PD controller does not control sufficiently.
Configuration options of the P(ID) controller
The following configuration options are available for a PID controller:
• Change control gain Kp (P influence)
• Set integral action time Tn (I influence)

If you do not yet have any experience for setting the control parameters, set the values
that yield the greatest possible stability in the control circuit. Proceed as follows to
optimize the control circuit further:
• Increase the control gain Kp until the controlled variable just starts to overshoot.
• Reduce Kp slightly again and then reduce the integral action time Tn so that the shortest
possible correction time without overshooting is achieved.
• To reduce the response time of the controller, also set the derivative action time Tv.

Actuating signal outputs via contacts (R247 to R2410 and R257 to R2510)
Each control contact outputs a cyclical signal whose intensity corresponds to the
controller's actuating value. A distinction is made according to the type of signal cycle:
• Pulse length modulation
The bigger the calculated manipulated variable is, the longer the contact affected
remains picked up. The period T can be adjusted between 0.5 and 99 s (field R248 or
R258). Outputs with pulse length modulation are used to activate solenoid valves.
• Pulse frequency modulation
The bigger the calculated manipulated variable is, the higher the switching frequency of
the contact affected. The maximum switching frequency 1/T can be set between 60 and
180 min-1 (field R249 or R259). The on-time ton is constant. It depends on the set
maximum frequency and is approx. 0.5 s for 60 min-1 and approx. 170 ms for 180 min-1.
170 ms. Outputs with pulse frequency modulation are used to activate directly controlled
solenoid dosing pumps.

Timer for cleaning function
This function includes a simple cleaning option. You can set the time interval after which
cleaning should start. Therefore you can only select a constant interval sequence.
Other cleaning functions are available for selection in conjunction with the Chemoclean
function (device version with four contacts required, see the "Chemoclean function"
section).
The timer and Chemoclean do not work independently of one another. While one of
the two functions is active, the other cannot be started.

Chemoclean function
Just like the timer function, Chemoclean can also be used to start a cleaning cycle.
However, Chemoclean also gives you the added option of defining various cleaning and
rinsing intervals and of dosing cleaning agent.
Therefore, it is possible to clean irregularly with different repeat cycles and to separately
set the cleaning times with post rinse times.
Please note the following:
• To use the Chemoclean function the transmitter has to be equipped with a designated
relay board (see product structure or chapter "accessories").
• The timer and Chemoclean are mutually dependent. While one of the two functions is
active, the other cannot be started.
• For the Chemoclean function, the relays 3 (water) and 4 (cleaner) are used.
• If the cleaning is prematurely aborted, a post rinse time always follows.
• If the setting is "Economy", cleaning only takes place with water.

When calibrating the "Free chlorine" measurement mode, make sure to pay attention
to the pH value and the temperature of the medium. The limit values are provided in
the following table:

Please note the following:
• You require a photometer, e.g. PF-3 (see "Accessories") to calibrate chlorine and chlorine
dioxide. A photometer with a higher accuracy rating and lower detection limit is required
for calibration in the trace range (<0.1 mg/l).
• If the calibration is aborted by simultaneously pressing the PLUS and MINUS keys
(return to C15, C29 or C35), or if the calibration is incorrect, the original calibration data
are used again. A calibration error is indicated by “ERR” and the sensor symbol flashes
on the display.
Repeat calibration!
• For each calibration, the device automatically switches to hold (factory setting).
• On completion of the calibration, the device returns to the measurement mode. The
"hold" symbol appears on the display during the hold dwell period (field S4).

Trouble shooting instructions
The transmitter continuously monitors its functions itself. If an error occurs which the
device recognizes, this is indicated on the display. The error number is shown below the
display of the main measured value. If more than one error occurs, you can call these up
with the MINUS key.
Refer to the "System error messages" table for the possible error numbers and remedial
measures.
Should a malfunction occur without any transmitter error message, please refer to the
"Process-specific errors" or the "Device-specific errors" tables to localize and rectify the error.
These tables provide you with additional information on any spare parts required.

Maintenance
LWARNING
Process pressure and temperature, contamination, electrical voltage
Risk of serious or fatal injury
‣ If the sensor has to be removed during maintenance work, avoid hazards posed by
pressure, temperature and contamination.
‣ Make sure the device is de-energized before you open it.
‣ Power can be supplied to switching contacts from separate circuits. De-energize these
circuits before working on the terminals.
Take all the necessary precautions in time to ensure the operational safety and reliability
of the entire measuring point.
The maintenance of the measuring point comprises:
• Calibration
• Cleaning the controller, assembly and sensor
• Checking the cables and connections
When performing any work on the device, bear in mind any potential impact this may
have on the process control system or on the process itself.
NOTICE
Electrostatic discharge (ESD)
Risk of damaging the electronic components
‣ Take personal protective measures to avoid ESD, such as discharging beforehand at PE
or permanent grounding with a wrist strap.
‣ For your own safety, only use genuine spare parts. With genuine parts, the function,
accuracy and reliability are also ensured after maintenance work.
9.1
Maintenance of the entire measuring point
9.1.1
Cleaning the transmitter
Clean the front of the housing using commercially available cleaning agents only.
The front of the housing is resistant to the following in accordance with DIN 42 115:
• Ethanol (for a short time)
• Diluted acids (max. 2% HCl)
• Diluted alkaline solutions (max. 3% NaOH)
• Soap-based household cleaning agents
When performing any work on the device, bear in mind any potential impact this may
have on the process control system or on the process itself.

Maintenance
Liquisys M CCM223/253
NOTICE
Prohibited cleaning agents
Damage to the housing surface or housing seal
‣ Never use concentrated mineral acids or alkaline solutions for cleaning.
‣ Never use organic cleaners such as benzyl alcohol, methanol, methylene chloride,
xylene or concentrated glycerol cleaner.
‣ Never use high-pressure steam for cleaning purposes.
9.1.2
Cleaning the pH/mV sensors (EP version)
LCAUTION
Cleaning not switched off during calibration or maintenance activities
Risk of injury due to medium or cleaning agent
‣ If a cleaning system is connected, switch if off before removing a sensor from the
medium.
‣ If you wish to check the cleaning function and have therefore not switched off the
cleaning system, please wear protective clothing, goggles and gloves or take other
appropriate measures.
LCAUTION
Risk of injury from cleaning agents
‣ When using the following cleaning agents, make sure to protect your hands, eyes and
clothing.
Please clean contamination on the glass electrodes as follows:
• Oily and greasy films:
Clean with hot water or temperature-controller detergent (grease remover, e.g. alcohol,
acetone, possibly dishwashing detergent).
• Lime and metal hydroxide buildup:
Dissolve buildup with diluted hydrochloric acid (3 %) and then rinse thoroughly with
plenty of clear water.
• Sulfidic buildup (from flue gas desulfurization or sewage treatment plants):
Use a mixture of hydrochloric acid (3 %) and thiocarbamide (commercially available) and
then rinse thoroughly with plenty of clear water.
• Buildup containing proteins (e.g. food industry):
Use a mixture of hydrochloric acid (0.5 %) and pepsin (commercially available) and then
rinse thoroughly with plenty of clear water.
• Fibers, suspended substances:
Pressurized water, surface-active agents if necessary
• Light biological buildup:
Pressurized water
ORP electrodes:
Carefully clean the metal pins or surfaces mechanically.
After mechanical cleaning, the ORP sensor can require several hours conditioning
time. For this reason, check the calibration after one day.
ISFET sensors
• Never use acetone to clean ISFET sensors as this could damage the material.
• After being cleaned with compressed air, ISFET sensors require approx. 5 to 8 minutes
until the closed-control loop is re-established and the measured value has adjusted to
the real value.
Clogged membranes can be cleaned mechanically under certain circumstances (does not
apply to ISFET sensors, Teflon membranes and open ring junction electrodes):
• Use a small warding file.
• Only file in one direction.

Liquisys M CCM223/253
Maintenance
Air bubbles in the electrode:
• Air bubbles can indicate incorrect mounting. For this reason check the orientation.
• The range 15° to 165° to the horizontal is allowed (ISFET sensors are the exception).
• Not permitted: horizontal installation or installation with the plug-in head pointing
downwards.

Permitted angle of installation for glass electrodes
Check for reference system reduction
The inner reference lead of the reference system (Ag/AgCl) of a combination electrode or
a separate reference electrode is usually brownish and matt. A silver-colored reference
system is reduced and therefore defective. This is caused by a current flowing through the
reference element.
Possible causes for the current flow:
• Incorrect measuring device operating mode selected (PML pin connected, but operating
mode asymmetrical ("without PML"). See also the function description for "Selecting the
connection type".
• Shunt in measuring cable (e.g. due to moisture) between reference line and grounded
shield or PM line.
• Measuring device defective (shunt in reference input or entire input amplifier
downstream of PE).

9.1.5
Maintenance of pH connecting cables and junction boxes (EP
version)
Check the cables and connections for moisture. Moisture is indicated by a sensor slope that
is too small. If nothing more can be displayed or if the display is fixed at pH 7, please check
the following components:
• Sensor head
• Sensor plug
• Junction box, if fitted
• Extension cable
NOTICE
Incorrect measurements caused by moisture in the measuring cable
‣ If there is moisture in the measuring cable, the cable must be replaced!
A shunt in the cable of > 20 MΩ cannot be measured with normal multimeters but is
damaging for the pH measurement. Connect a pH simulator instead of the sensor. The
value that is displayed on the transmitter must match the value set at the simulator. The
value can differ at the second decimal place at the very maximum.
If you do not have a pH simulator, you can test the cable with a commercially available
megohmmeter. Please note the following when performing the test:
• Make sure to disconnect the pH measuring cable from the sensor and device!
• If you are using a junction box, you should check the infeed and outfeed measuring cable
separately.
• Check the cable with 1000 V DC (at least with 500 V DC) testing voltage.
• If the cable is intact, the insulation resistance is > 100 GΩ.
• If the cable is defective (moist), there is flashover.
The cable must be replaced.
You can clean (desalinate) the sensor head and junction box with de-ionized water
and dry them with a hot air dryer.

Test and simulation
9.2.1
Chlorine sensors
Chlorine sensors work according to the amperometric principle and supply very small
direct currents as the measuring signal.
A chlorine sensor can be simulated by a DC source. Due to the small currents, however, the
simulation is highly sensitive. Use shielded cables and ground the simulator. Typical slope
values are provided in the table below:

CCS140
Approx. 25 nA per mg Cl/l

9.2.2
Temperature measurement
The transmitter uses the NTC sensor of the chlorine sensor to measure the temperature.
Due to the relatively high sensor resistance, a two-wire connection is sufficient.
Simulation can be performed with a normal decade resistor. The table below contains
some simulation values:
Temperature
NTC simulation value
0 °C (32 °F)
29.490 kΩ
10 ° C (50 °F)
18.787 kΩ
20 °C (68 °F)
12.268 kΩ
25 °C (77 °F)
10.000 kΩ
30 °C (86 °F)
8.197 kΩ
40 °C (104 °F)
5.594 kΩ
9.2.3
pH/ORP measurement
Simulation is performed with a pH/mV simulator or an mV voltage source.
In the case of the CCM223/253, the pH or mV must always be measured
symmetrically. For this reason, each simulation requires potential matching with the
simulator. Connect the reference signal of the simulator (normal shield of the pH
coaxial measuring line) to the PA/PM terminal of the transmitter.
Zero point rapid test
• In the case of the panel-mounted device, connect the BNC inner conductor to the BNC
receptacle and the PM terminal.
• In the case of the field device, connect the pH terminal, the Ref terminal and the PM
terminal.
• For pH the reading must be approx. 7, and for ORP approx. 0 mV.

Replacing the central module
Generally, when a central module has been replaced, all data which can be changed
are set to the factory setting.
If possible, note the customized settings of the device, such as:
• Calibration data
• Current assignment, main parameter and temperature
• Relay function selections
• Limit value/controller settings
• Cleaning settings
• Monitoring functions
• Interface parameters
Proceed as described below if a central module is replaced:
1.
Disassemble the device as explained in the "Dismantling the panel-mounted
instrument" or "Dismantling the field instrument" section.
2.
Use the part number on the central module to check whether the new module has
the same part number as the previous module.
3.
Reassemble the device with the new module.
4.
Put the device back into operation and check the basic functions (e.g. measured value
and temperature display, operation via keyboard).
5.
Read the serial number (“ser-no.”) off the nameplate of the device (e.g.
6A345605G00) and enter this number in fields E115 (1st digit = year, one-digit (6
in the example)), E116 (2nd digit: month, one-digit (A in the example)), E117 (digits
3-6 cons. number, four-digit (3456 in the example)).
In the field E118, the complete number is displayed again so you can check it is
correct.
You can only enter the serial number for new modules with the serial number 0000.
This can only be done once! For this reason, make sure the number entered is correct
before you press ENTER to confirm!
If an incorrect code is entered, the additional functions are not enabled. An incorrect
serial number can only be corrected at the factory!
1.
Press ENTER to confirm the serial number or cancel the entry to enter the number
again.
2.
If available, enter the release codes for the Plus Package and/or Chemoclean in the
"Service" menu.
3.
Check the Plus Package release (e.g. by opening the function group CHECK / Code P)
or the Chemoclean function.
4.
Make the customized device settings again.
