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

Types of chlorine

A distinction is made between free chlorine and combined chlorine.

Free chlorine

Liquisys M CCM223/253 Commissioning

Endress+Hauser 45

Free chlorine is understood as the sum of elementary chlorine (Cl

), 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 (NH

) or ammonium (NH

) 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 (Cl

) 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.

 31 Basic representation of pH compensation

A Measured value with pH compensation

B Measured value without pH compensation

C 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 (Cl

) form quickly. This compound is formed in various

Commissioning Liquisys M CCM223/253

46 Endress+Hauser

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.

Liquisys M CCM223/253 Commissioning

Endress+Hauser 47

Calibration of the complete measuring system makes sense only up to a pH value of the

medium of 8 or 8.2.

Sensor pH value HOCl content Uncompensated value Compensated value

CCS141 8.2 15 % 12 nA 80 nA

CCS140 8 20 % 4 nA 20 nA

Above these pH values, the total error of the measuring system is unacceptably high.

7.4.3 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 in main stream Current signal in mA Current input signal in %

Flowmeter start of measuring range 4 0

Flowmeter end of measuring range 20 100

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).

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

Liquisys M CCM223/253 Commissioning

Endress+Hauser 57

measuring signal to be very sluggish or not even change at all (constant signal). This

passive behavior is detected and signaled by constantly monitoring the signal activity.

7.4.7 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.

Liquisys M CCM223/253 Commissioning

Endress+Hauser 61

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 K

(P influence)

• Set integral action time T

(I influence)

• Set derivative action time T

(D influence)

Basic load dosing (basic)

You can set a constant dosage amount (field R2411) with basic load dosing (field R241).

PID control plus basic load dosing

If you have selected this function (PID + Basic) in field R241, the PID-controlled dosage

amount does not drop below the basic load value entered in field R2411.

Commissioning

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 K

until the controlled variable just starts to overshoot.

• Reduce K

slightly again and then reduce the integral action time T

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 T

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 t

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.

• Inverse control action = minimum function

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.

7.5 Calibration

Use the CAL key to access the calibration function group.

Use this function group to calibrate the transmitter.

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:

Sensor pH

min

max

min

max

CCS140 4 8 10 °C (50 °F) 45 °C (113 °F)

CCS141 4 8.2 2 °C (36 °F) 45 °C (113 °F)

CCS240 - - 2 °C (36 °F) 45 °C (113 °F)

CCS120 5.5 9.5 5 °C (41 °F) 45 °C (113 °F)

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).

8 Diagnostics and troubleshooting

8.1 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.

9 Maintenance

WARNING

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.

9.1.2 Cleaning the pH/mV sensors (EP version)

CAUTION

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.

CAUTION

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

Endress+Hauser 97

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.

> 15°

 44 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).

9.1.3 Maintenance of chlorine sensors

Please refer to the Operating Instructions for your sensor for sensor maintenance and

troubleshooting:

CCS120 BA00388C/07/EN

CCS140/141 BA00058C/07/EN

CCS240/241 BA00114C/07/EN

963 BA00039C/07/EN

The Operating Instructions contain detailed information including:

• Sensor design and function

• Mounting and installation

• Electrical connection

• Commissioning and calibration

• Calculation examples and tables for verification of measured values

• Maintenance, regeneration, cleaning

• Troubleshooting table

• Accessories and spare parts

• Technical data and ordering information

9.1.4 Assembly

Refer to the assembly operating manual for information on servicing and troubleshooting

the assembly. The assembly operating manual describes the procedure for mounting and

disassembling the assembly, replacing the sensors and seals, and contains information on

the material resistance properties, as well as on spare parts and accessories.

Maintenance Liquisys M CCM223/253

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.

9.2 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:

Sensor Typical slope value

CCS120 Approx. 115 nA per mg Cl/l

CCS140 Approx. 25 nA per mg Cl/l

CCS141 Approx. 80 nA per mg Cl/l

CCS240 Approx. 100 nA per mg ClO

CCS241 Approx. 350 nA per mg ClO

963 Approx. 20 μA per mg Cl/l

Liquisys M CCM223/253 Maintenance

Endress+Hauser 99

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.

Test with DC supply point

pH value Simulation

2 295 mV

4 177 mV

7 0 mV

9 -118 mV

12 -295 mV

9.2.4 Flow monitoring

Flow is monitored by an inductive proximity switch (INS) in the CCA250 assembly. This

switch is powered by 15 V from the auxiliary voltage output of the transmitter.

Function of the INS

Flow INS INS output

Yes damped low impedance

No not damped high-impedance

If you connect terminal 93 to terminal 85 and terminal 94 to terminal 86, this simulates

an active proximity switch and thus a correct flow.

Do not run the measuring system continuously in this state. Reestablish flow

monitoring as soon as possible!

10.4 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.
