Note the following when erecting the device:• Always lay the suction line so that it slopes upwards from the sampling point to thesampler.
• The sampler must be located above the sampling point.
• Avoid siphoning effects in the suction line.
Requirements for the sampling point:• Do not connect the suction line to pressurized systems.
• Use the suction filter to impede coarse and abrasive solids and solids which can cause
clogging.
• Immerse the suction line in the direction of flow.
• Take the sample at a representative point (turbulent flow, not directly at the bottom of
the channel).
Useful sampling accessories
Suction filter:
Impedes coarser solids and solids which can cause clogging.

• Cable glands (up to 8 depending on the version) are available for the cable entry.
• The cable length from the foundation to the terminal connection is approx.
1.7 m (5.6 ft).
• For analyzer stands, the cable length is approx. 1.8 m (5.9 ft) from the foundation.

Liquistation CSF28

Function

Info

Power failure

Decide how the sampler should react when it is energized after a power failure.
Resume program:• Time and flow-paced
The program calculates the omitted samples and enters them in the logbook
as failed. When the program is restarted, it continues where it wasinterrupted.
• Flow-paced
No samples are entered in the logbook during the power failure. When the
program is restarted, it continues where it was interrupted.

Sample volume

Time paced CTCV
A constant sampling volume is taken at steady intervals.
Flow paced VTCVA constant sampling volume is taken at variable intervals.
Time/flow paced CTVV
A variable sampling volume is taken at steady intervals.

38

Sampling interval

Set the sampling interval.
The pulses are scaled at the flowmeter. By multiplying the pulses at the samplinginterval, the shortest sampling interval at the maximum pulse frequency can be
set. Example: With a maximum flow rate of 600 m3 (21188ft3)/h, the pulse
frequency at 5 m3 (176.57 ft3) is 120 pulses/h or 2 pulses/min. With a samplinginterval of 20 m3 (706 ft3), a sample is taken after 4 pulses = 2 minutes.

Bottle synchronization

The bottle synchronization setting is possible with all types of program. Bottle
synchronization is only possible with a bottle change after a specific time and notwith a bottle change after a number of samples.
Specific bottles can be assigned specific filling times with the bottle
synchronization function. For example, bottle 1 is to be filled from midnight to 2a.m., bottle 2 from 2 a.m. to 4 a.m. etc.

Stop condition

Use this function to enter the end of the program and to specify continuous
operation.
End of program: the program stops automatically once it has gone through all
the bottles once.
Continuous operation: the program runs in a continuous loop. The bottles must
be emptied regularly.

In accordance with NAMUR specification NE 107, the diagnostic messages arecharacterized 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.
• 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, a shorter
operating life or lower accuracy levels. The cause of the problem is to be found outside
the measuring point.
• M = Maintenance required. Action must be taken as soon as possible
The device still measures/takes samples correctly. Immediate measures are notnecessary. However, proper maintenance efforts would prevent a possible malfunctionin the future.

Maintenance

LWARNING
Touching moving parts during operation.
Pinching/crushing or severe injuries to hands and fingers.
‣ Stop the program.
‣ Disconnect the device from the mains.
Effects on process and process control‣ Take all the necessary precautions in time to ensure the operational safety andreliability of the entire measuring point.

LWARNING
Process pressure and temperature, contamination, electrical voltage
Risk of serious or fatal injury‣ 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 thesecircuits before working on the terminals.
NOTICE
Electrostatic discharge (ESD)
Risk of damaging the electronic components‣ Take personal protective measures to avoid ESD, such as discharging beforehand at PEor permanent grounding with a wrist strap.
‣ For your own safety, use only genuine spare parts. With genuine parts, the function,accuracy and reliability are also ensured after maintenance work.

LCAUTION
Possibility of microbiological contamination of content of sample bottles.
Minor to medium injury possible.
‣ Wear suitable protective clothing.

12.1

Maintenance work

12.1.1

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
ensure that 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. A maintenance contract
increases the operational safety of your device and reduces your staff's workload. Ask
your Endress+Hauser Service Organization for detailed information on maintenancecontracts.

Calibration

Distribution arm
The position of the distribution arm is set at the factory. It is only possible to calibrate the
distribution arm in the version with multiple bottles.
The distribution arm must be calibrated if:• The distribution arm motor has been replaced• Error message "F328 Distribution arm" appears on the display
Proceed as follows to calibrate the distribution arm:
1.

Under menu Application/Calibration/Distribution arm/Go to ref. point The reference run is started. The reference point is in the middle at the front. For
the version with a distributor plate, the reference point is at the arrow in the
middle of the plate.
With Adjust, you can correct the distribution arm if the unit does not move to thereference point correctly. Use the two arrow keys to correct the position.

2.
Sample volume or vacuum pump
The dosing volume of the vacuum pump is set to 200 ml (6.76 oz) at the factory. The
required sample volume is set by moving the dosing pipe manually.
NOTICE
Calibration not possible during operation.
The sample volume cannot be determined.
‣ Stop the sampling program before calibrating the sample volume.

Reinstall the parts in reverse order. Make sure that the contacts of the conductivity
sensors are in the correct position.

5.

Check that the dosing tube is set correctly by performing manual sampling.

Peristaltic pump sample volume
The sample volume of the peristaltic pump is calibrated at the factory.
In order to calibrate the sample volume, a graduated beaker with a volume of at least 200
ml (6.76 oz) is required.
1.

In the menu select Application/Calibration.

2.

Enter the desired volume under Sample volume.

3.

Start sampling.
