1.1 Designated use

Liquiline CM42 is a two-wire transmitter for liquid analysis in all areas of process engineering:

• Chemical processes

• Pharmaceutical industry

• Food technology

If the device is used for any purpose other than that described, this poses a threat to the safety

of people and the entire measuring system and is thus not permitted.

The manufacturer does not accept liability for damage caused by improper or non-designated

use.

1.2 Incoming acceptance, transport, storage

• Make sure the packaging is not damaged!

Inform your supplier of any damage to the packaging.

Please keep the damaged packaging until any issues have been resolved.

• Make sure the contents are not damaged!

Inform your supplier of any damage to the contents.

Please keep the damaged goods until any issues have been resolved.

• Check the scope of delivery against the delivery papers and your order to ensure it is complete

and nothing is missing.

• Pack the device in such a way as to protect it reliably against impact and moisture for storage

and transportation. Optimum protection is provided by the original packaging materials. In

addition, the permitted ambient conditions must be observed (see Technical data).

• If you have any queries, please contact your supplier or local sales center.

1.3 Installation, commissioning and operation

Observe the following points:

• Installation, commissioning, operation and maintenance of the measuring system must only

be carried out by trained technical personnel.

The technical personnel must be authorized to perform the tasks by the owner-operator.

• The electrical connection may only be established by an electrical technician.

• The technical personnel must have read and understood these Operating Instructions and

must follow the instructions they contain.

• Prior to commissioning the entire measuring point, check that all connections are correct.

Make sure that electric cables and hose connections are not damaged.

• Do not commission damaged products. Protect them against unintentional start-up. Label and

identify the damaged product as defective.

• Faults at the measuring point may only be rectified by authorized and properly trained

personnel.

Liquiline M CM42 Safety instructions

Endress+Hauser 5

• If the faults cannot be eliminated, take the products out of service and protect them against

The smallest possible spread between4 mA and

20 mA value is:

1 for pH, 1 mV for ORP mV

Up value (20 mA) –1.5 ... 16 pH or

–600 ... +700 mV

Factory setting

12 pH

6.3.1 User roles and access authorization

If the password protection has been defined and activated, you have to log in with the

appropriate user role before you can make changes to the settings in the menu.

Here, you will be prompted by the device to enter an access code as soon as you want to

configure a value:

User roles and access authorization (factory setting):

! Note!

If you are logged in as the "Specialist" (=Administrator), you can change the access

authorization of all other user groups:

1. Select a submenu where you want to assign authorization to, or take authorization from,

another user group.

2. Press and hold down the navigator button for at least 3 seconds.

The display shows all the user groups and the current access authorization to the menu

selected.

3. Use the navigator to change the authorization in question and confirm with "OK".

4. Make a note of the changes in your operating logbook or similar.

6.4 Calibration

Calibration is necessary:

• At initial commissioning

• After replacing a sensor

Maintenance team Specialist Operator

• Read access in the PARAM and

DIAG menus

• Read and write access in the

calibration menu

• Read and write access in all menus

• Change the access authorization

for other user groups

• Read access in the PARAM and

DIAG menus

• Read authorization in the

calibration menu


Endress+Hauser 29

• After periods of standstill

• At sensible, process-dependent intervals1).

6.4.1 Types of calibration

• Automatic buffer recognition (only pH):

– "PARAM"/"Sensor"/"Cal-settings"/"Buffer manufacturer" or

"PARAM"/"Quick Setup"/"Buffer manufacturer"

– You select the buffer type (e.g. DIN 19266).

– The device automatically recognizes the buffer during calibration.

• Fixed buffer (only pH):

– "PARAM"/"Sensor"/"Cal-settings"/"Buffer recognition"

– You select two buffer solutions from the menu.

• Manual:2)

– You enter the buffer values during calibration.

• Numeric input:

– "PARAM"/"Sensor"/"Cal-settings"/"Type of calibration"

– You enter the slope, zero point and temperature (for pH).

– You enter the mV value (for ORP).

6.4.2 Calibrate

Proceed as follows to calibrate the sensor:

1. Go through the menu "Param"/"Quick Setup" completely 3).

2. Remove the sensor from the process.

3. Clean the sensor.

4. Press the soft key for "CAL".

5. Follow the instructions in the menu.

6. Finish calibrating by switching back to the measuring mode.

7. Install the sensor back into the process.

Your measuring point is now ready for operation.

! Note!

• If calibration is aborted using ESC, or if the calibration is faulty, the system continues to use

the original calibration data. A calibration error is shown as plain text on the display.

• During each calibration, the device automatically switches to Hold (factory setting).

• Any offset set is automatically deleted after accepting the calibration.

1) Depending on the process conditions, the intervals can range from several times daily to once quarterly.

2) Not available during initial commissioning if you are working with the factory settings.

3) Only for initial commissioning
