 The device starts up and transmits the measured value as a current value.

To operate via the SmartBlue, the Bluetooth® LE signal on the smartphone or tablet must
be switched on.

9.2 Function check

WARNING

L

Incorrect connection, incorrect supply voltage

Safety risks for staff and device malfunctions!

Check that all connections have been established correctly in accordance with the

wiring diagram.
Ensure that the supply voltage matches the voltage indicated on the nameplate.

‣

Familiarize yourself with the operation of the device before it is first switched on. In
particular please read the "Basic safety instructions" sections. After power-up, the device
performs a self-test and then goes to the measuring mode.

9.4 Establishing a connection via RIA15

The RIA15 can be used as a local indicator of the measured values as well as for basic
configuration of the Liquiline CM82 via HART®.

Here, the RIA15 communicates with the CM82 via HART as a secondary master in
addition to the PLC or process control system. The RIA15 is not invisible to the PLC in this
case. The RIA15 does not alter the current value of the current output of the CM82.

"UC170" displayed instead of HART® unit

By default, the unit of the transmitted measured value is automatically read out and
displayed using a HART® command. If the transmitted "unit code" cannot be uniquely
assigned by the RIA15, the unit code (UC170) is displayed instead of the unit. To remedy
this, the unit must be set manually. (SETUP => HART => HART1-4 => UNIT1-4 =>
TEXT1-4).

The unit codes 170 to 219 are assigned multiple times as per the HART® specification. As
the UC170 is also used with the CM82, the unit must be assigned manually. This applies to

For the other types of compensation, specify a

changed by the user.

If the user-defined password is lost, access can be restored via a recovery password.

The recovery password is the serial number of the device in reverse.

tablet.

• The Bluetooth® wireless technology interface can be disabled via the SmartBlue.

• Bluetooth® is optional. It can be ordered with this functionality enabled.
If ordered with Bluetooth® disabled, Bluetooth® can be enabled at a later stage by means
of an activation code (accessory kit) linked to the serial number.

• If the Bluetooth® interface has been disabled, it can be reactivated only via HART.

In accordance with Namur specification NE 107, the diagnostic messages are characterized
by:

• Message number

• Error category (letter in front of the message number)
– F = (Failure) a malfunction has been detected
– C = (Function check), (no error)

Maintenance work is being performed on the device. Wait until the work has been
completed.

– S = (Out of specification), the measuring point is being operated outside its

specification
Operation is still possible. However, you run the risk of increased wear, shorter
operating life or lower measurement accuracy. The cause of the problem is to be found
outside the measuring point.

– M = (Maintenance required), action should be taken as soon as possible

• Sensor type:

Maintenance Liquiline Compact CM82

12 Maintenance

The maintenance of the measuring point comprises:

• Calibration

• Cleaning the controller, assembly and sensor

• Checking the cables and connections.

WARNING

L

Process pressure and temperature, contamination

Risk of serious or fatal injury

If the sensor has to be removed during maintenance work, avoid hazards posed by

‣

pressure, temperature and contamination.

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.

12.1 Maintenance tasks

12.1.1 Cleaning

NOTICE

Cleaning agents not permitted

Damage to housing surface and optical waveguide

Never use concentrated mineral acids or alkaline solutions for cleaning.

‣

Never use organic cleaners such as acetone, benzyl alcohol, methanol, methylene

‣

chloride, tetrahydrofuran, xylene or concentrated glycerol cleaner.

The device is resistant to:

• Ethanol (for a short time)

• Diluted acids (max. 2% HCl)

• Diluted bases (max. 3% NaOH)

• Soap-based household cleaning agents

• Washing-up liquid

12.1.2 Calibration

To calibrate the sensor, remove it from the medium and calibrate it in the laboratory. Since
Memosens sensors save the data, you can always work with "precalibrated" sensors and do
not have to stop monitoring the process to perform a calibration.

1. Menu: Guidance/Calibration menu item.

2. Select calibration type.

3. Follow the instructions of the software.

4. Return the sensor to the medium.
 This deactivates the hold and the system starts measuring again.

You can cancel the calibration by pressing X. No data are then used to adjust the sensor.
