General troubleshooting

1.1.1 Troubleshooting
A diagnostic message appears on the display or via the fieldbus indicating that the measured
values are not plausible, or you identify a fault.
1. See the Diagnostics menu for the details on the diagnostic message.
 Follow the instructions to rectify the problem.
2. If this does not help: Search for the diagnostic message under "Overview of diagnostic
information" () in this manual. Use the message number as a search criterion. Ignore theletters indicating the Namur error category.
 Follow the troubleshooting instructions provided in the last column of the error tables.
3. If the measured values are implausible, the onsite display is faulty or you encounter otherproblems, search for the faults under "Process errors without messages" () or "Device-specificerrors" ().
 Follow the recommended measures.
4. Contact the Service Department if you cannot rectify the error yourself. Only cite the error
number.

Adjusting diagnostic information

1.5.1 Classification of diagnostics messages
More detailed information on the current diagnostics messages displayed is provided in the
DIAG/Diagnostics list menu.
In accordance with Namur specification NE 107, the diagnostics messages are characterized by:• Message number• Error category (letter in front of the message number)– F = (Failure) a malfunction has been detected
The cause of the malfunction is to be found in the sampling point/measuring point. Any
controller connected should be set to manual mode.
– M = (Maintenance required) Action should be taken as soon as possible
The device still measures/takes a sample correctly. Immediate measures must not be taken.
However, proper maintenance efforts would prevent a possible malfunction in the future.
– 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 accuracy levels. The cause of the problem is to be found outside the measuring
point.
• Message text
If you contact the Service Department, please cite the message number only. Since you can
individually change the assignment of an error to an error category, the Service Department
cannot use this information.
1.5.2 Adjusting the device behavior
All the diagnostics messages are assigned to specific error categories at the factory. Since othersettings might be preferred depending on the application, error categories and the effect errors
have on the measuring point can be configured individually. Furthermore, every diagnostics
message can be disabled.
ExampleThe controller returns diagnostics message 531 "Logbook full". You want to change this message
so that an error is not indicated on the display for example.
1. Go to:– Menu/Setup/General settings/Extended setup/Diagnostics/Device behavior
for device-specific diagnostics messages (as in this example)– Menu/Setup/Inputs/<Sensor type>/Extended setup/Diagnostics settings/Diag.

Maintenance! WARNING
Process pressure and temperature, contamination, electrical voltage
Danger! Risk of serious or fatal injury!
‣ De-energize the device before removing the rear panel.
‣ Power can be supplied to switching contacts from separate circuits. De-energize thesecircuits before working on the terminals.
‣ If a 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.
‣ For your own safety, only use genuine spare parts. With genuine parts, the function,accuracy and reliability are also ensured after maintenance work.

2.1

Recommended maintenance

Maintenance work has to be carried out at regular intervals to ensure the efficient operation of
the sampler.
The maintenance work comprises:• Replacing the wear parts• Cleaning the device
The cleaning intervals depend heavily on:• The medium• The ambient conditions of the sampler (dust etc.)• The programming intervals
For this reason, adapt the cleaning intervals to your specific requirements but always ensurethat these cleaning tasks are performed regularly.
Replacing wear parts
Wear parts are replaced by Endress+Hauser Service at one- and two-year intervals. Pleasecontact your local sales center in this regard.
Endress+Hauser offers its customers a maintenance contract. With a maintenancecontract, you can increase your level of operational safety and relieve your operating staff
of some of their workload. Ask your Endress+Hauser Service Organization for detailed
information on maintenance contracts.

If an error occurs or the maintenance schedule stipulates that the sensor has to be
replaced, use a new sensor, or a sensor that has been precalibrated in the laboratory.
A sensor is calibrated in the laboratory under optimum external conditions, thereby
ensuring better quality of measurement.
Remove the sensor to be serviced and install the new sensor.
You must perform calibration if you use a sensor that is not precalibrated.
The sensor data are automatically accepted by the transmitter. A release code is not
required.
Measurement is resumed.

Take the used sensor back to the laboratory. In the laboratory you can get the sensor readyfor reuse while ensuring the availability of the measuring point.
– Clean the sensor. For this purpose, use the cleaning agent specified in the sensor
manual.
– Inspect the sensor for cracks or other damage.
– If no damage is found, regenerate the sensor. Where necessary, store the sensor in aregeneration solution (--> sensor manual).
– Recalibrate the sensor for reuse.

2.3.6 Assemblies (for version with sensors with the Memosens protocol)
Refer to the assembly operating manual for information on servicing and troubleshooting theassembly. The assembly operating manual describes the procedure for mounting anddisassembling the assembly, replacing the sensors and seals, and contains information on thematerial resistance properties, as well as on spare parts and accessories.

Calibration

Distribution arm
The position of the distribution arm is set at the factory.
Sampling volume
The sample volume of the peristaltic pump is also calibrated at the factory. The dosing volumeof the vacuum pump is preset to 200 ml at the factory.
For version with sensors with the Memosens protocol:
Users must decide whether the process conditions present require calibration during initialcommissioning.
Additional calibration is not required in many standard applications.
Sensors with Memosens protocol are calibrated at the factory.
Calibrate the sensors at sensible intervals depending on the process.
All information on calibration is provided in BA00467C "Calibration".

2.6

Technical support
We recommend the purchase and use of an SD card (see accessories). You can save theentire sampler configuration on the SD card (see -> BA00464C "Operation & settings", "Datamanagement" section) and make the data available to the service team should you be inneed of technical assistance.
