Installation

Characteristics: sampler 4210

Compared to the standard samplers, the special sampler for sampling of faecal matter is equipped
with a rinsing unit in the metering vessel and an additional outlet. Furthermore the sample is filled
directly into the bottles. The section from the metering vessel to the distributor outlet is rinsed.

Method of operation: The metering vessel is rinsed automatically after each sample extraction.
To do this, the distributor arm first moves on the discharge position and
then back on the bottle. Thus a sample contamination is avoided.

The picture shows the metering vessel with additional rinsing water
connection.

The rinsing head (arrow) can be seen after having removed the
metering vessel.

Operation

Installing the apparatus

- The workings described in this chapter of the manual must only be carried out by qualified

personnel.

- We recommend to install the apparatus as near as possible to the point of extraction. If installed

outside, the device should be fixed on a solid flat base (e.g. plinth). The fixing bars do already
have the necessary fixing holes.

- If the device is equipped with castors (mobile version), please make sure that the two lock-type

castors are locked during operation.

- For better deaeration / ventilation install the apparatus with a distance of approx. 10 cm to the wall.

- The hose has to be laid with a continuous fall from the apparatus to the point of extraction, without

fail. Lower lying points can lead to deposits in the hose which may freeze up in winter.

- To fix the suction hose, we recommend to use the extraction unit available as accessory.

- Fix the hose in such a way that the suction aperture lies in the direction of flow, so that coarse

matter and fibres cannot be forced into the suction aperture.

Remark: To open the top cover both front screws (left + right)

have to be removed. Then the top cover can be lifted
up to the point where the retention bars snap-in. To
close the cover again, the two retention bars have to

be lifted slightly.
After having closed the cover, the
two screws (left + right) have to be screwed in again.

Mains connection The device is equipped with a power supply lead.
The connecting data can be found in chapter “Technical Data”.

Connect/disconnect The device is connected/disconnected by means of the mains plug (except

devices with main switch).

Hose routing The apertures for the suction hose are on the left and on the right at the front.
Signal inputs The signal inputs (e.g. for flow meter) are located on the „fold-out“ plate and

can be connected according to the plan of terminal connections shown there.

Messages The relays required for messages (up to 4) can be fixed on the top hat rail. For

details please see the circuit diagram

Remark:

The apparatus must be cleaned regularly in accordance with the degree of contamination present. In
view of the quality of samples, we recommend to clean thoroughly especially the wetted parts like
dosing unit, electrodes, distributor, bottles and inlet hose. Failure to do so could result in damage or

destruction to the equipment, device that are not covered by warranty.

Page 18 Manual BÜHLER BU4010ff

Operation

Sampling modes

The following sampling modes can be programmed:

Sampling mode Description Example
Time-

proportional

Flow-dependent

- digital

Flow-dependent

- analogue

In this sampling mode, the
single sample extractions as
well as the bottle change are
effected in fixed time intervals.

In this sampling mode the
sample extraction is triggered
by flow pulses. The bottle
change is effected in fixed time
intervals or after a certain
number of sample extractions.

In this sampling mode samples
are extracted according to the
analogue flow signal (0-20 mA
or 4-20 mA). The sample
extraction is started when the
programmed flow is reached.
Thus the interval between the
sample extractions varies
according to the flow signal.
The bottle change is effected in
fixed time intervals or after a
certain number of sample
extractions.

Values to program:
sampling interval
e.g. 00:05 hh:mm

Bottle filling time
e.g. 02:00 hh:mm

Values to program:
pulse divider
e.g. 100
(that means that a sample is
extracted after each 100th
pulse).

Bottle filling time
e.g. 02:00 hh:mm
or
bottle change after X sample
extractions e.g. 100

Values to program:
Flow per sample extraction
e.g. 1 m³

Bottle filling time
e.g. 02:00 hh:mm
or
bottle change after X sample
extractions e.g. 100

Flow­proportional

Page 21 Manual BÜHLER BU4010ff

Samples are not extracted with
a fixed volume but within a
fixed time interval (e.g. every
10 minutes).For this kind of
sampling, the variable
automatic dosing system
(available as option) is
required. This system is only
working with an analogue flow
signal!
The sample volume adapts

•Analogue signal (4-20 mA or
optional 0-20 mA)

•The max. sample volume at
20 mA is fixed to 200 ml.
At an analogue signal of e.g.
10 mA, a 100 ml sample would
be extracted accordingly.
Sampling is effected in a fixed
time interval of e.g. 10
minutes.
Thus the sample extraction is

Operation

Event­proportional

itself automatically
proportionally to the flow. This
is achieved by proportionally
scaling the mA signal and the
maximum sample volume. That
means, the sample volume is
automatically adjusted to the
mA
signal.

In this sampling mode the
sample extraction is depending
on an external event signal
(potential-free make contact).
The sample is only extracted as
long as the signal is present.
The sampling interval as well
as the bottle change are

3. Screw cap

4. Electrodes

5. Volume control tube

6. Metering vessel

7. Silicone discharge tube

8. Motor-driven pinch-valve

9. Air connection

Cleaning:

- Glass metering vessel: unscrew the screw cap (3) and remove the flange. Now, the metering
vessel together with the silicone discharge tube (7) can be detached.

- Plastic metering vessel: Turn the plastic metering vessel anticlockwise (bayonet fitting) and
remove.

Adjustment of sample shot volume at samplers with glass metering vessel:
To adjust the desired sample volume, loosen the knurled screw and displace the volume control tube
vertically.

Adjustment of sample shot volume at samplers with plastic metering vessel:
The sampler is always delivered with the volume control tube in full length.
To adjust the sample shot volume, the volume control tube (5) has to be cut
to length.

Procedure

1. There is a graduation in millilitres on the volume control tube.

2. Remove the metering vessel (6).

3. Cut the volume control tube to the desired length with scissors or a knife.

4. Reinstall the metering vessel (6) and tighten.

5. Check the sample volume by starting a manual sample extraction.

6. Now the device is ready for operation.

Remark: If you need to work with different sample volumes, you can cut to
size several tube pieces. As the volume control tube (5) is only
slipped on the hose connector (1), it is very easy to change the tube.

Page 23 Manual BÜHLER BU4010ff

Operation

Operation principle:

1. Inoperative
position

Replacement of the silicone discharge hose
The silicone hose (BM69301) is only pushed over the lip of the metering vessel. A hose clamp is not
required. Humidify the hose a little bit, fix it at one point and push it over the lip.

Remark:
Do only use original spare parts from the manufacturer. The use of a wrong hose type can lead to
malfunctions at the system or may even damage the pinch valve!

Remark:
Conductivity of the sample medium
There are two conductive level electrodes in the metering vessel. Their sensitivity can be adjusted in
the service menu. In the factory the electrodes are adjusted to tap water (this adjustment does not
have to be changed under normal operating conditions). Minimum conductivity 50 μS/cm.
Please note that a wrong adjustment can lead to a flooding of the pneumatic system and to the
damage of component parts.

The sampler is not suitable for extraction of distilled water due to low conductivity.
Conductivity at 25°C

Rain water 50 μS/cm
Drinking water 500 μS/cm
Waste water 5000 μS/cm (5 mS/cm)
Seawater 50000 μS/cm (50 mS/cm)

ATTENTION:
Wrong operating conditions can lead to malfunctions or may even damage the apparatus. No liability
or claims under guarantee will be accepted in respect of any damage arising from the non-observance
of these operating instructions.

Operation

Flow-proportional sampling system

The characteristic features of the flow-proportional sampling are:

• fixed sampling interval (e. g. every 10 min) with

• variable sample volume (related to the mA-signal (flow))
At the variable dosing system, the sample volume is automatically changed according to the analogue

flow signal.
Example: - the selected range is 4 to 20 mA (option 0 – 20 mA)

- the maximum sample volume at 20 mA is fixed to 200 ml.
That means at an analogue signal of e.g. 10 mA, a 100 ml sample would
be extracted. Thus the sample extraction is always proportional to the flow.

This sampling mode supplies very good, representative results as even if flow is very low (e.g.
discharges at night) a sample extraction is still carried out in fixed time intervals.

For comparison a short description of the flow-dependent sampling mode:
The characteristic features of the flow-dependent sample extraction are:

• variable sampling interval (according to the mA-signal (flow)) with

• fixed sample volume (e.g. 100 ml)
In the flow-dependent sampling mode, a sample is e.g. always extracted after 10 m³, that means the

signal of the flow meter is totalized.
In case of very low flow quantities (e.g. discharges at night) it is possible that e.g. 2-3 hours pass until
the set 10 m³ are reached again and a sample is extracted.

Remark: That means if there is an accident (e.g. discharge of chemicals) during this period, there
will be no sample. However, a sample would have been very important for an analysis and
the taking of countermeasures.

Page 26 Manual BÜHLER BU4010ff

Operation

Function of the VAR Flow-proportional sampling system

· Before the system can be used, it must be calibrated. In the automatic calibration cycles (5
cycles), the respective volumes must entered.

· At the flow-proportional (variable) sampling system the sample volume is directly entered in ml by
means of the keys at the control when editing a sampling program.

· After the program start the pinch valve is closed.

· A pressure (air produced by the diaphragm pump) is applied to the metering vessel via the air

connection. Thus the hose is purged.

· Now, the valve system switches to vacuum and the depression generated by the diaphragm pump
withdraws the air from the metering vessel. A vacuum is generated and leads to the drawing-off of
sample medium at the connected hose.

· The medium is sucked into the Dosingvessel over the Measuring tube (2).

· during inlet, the sample volume already will be measured in the measuring tube(2) and only the

requested volume remains in the vessel.

· After measuring is done, the system is ventilated by opening the air inlet (4) so that the water in
the suction hose can flow back to the extraction point.

· After a pre-programmed aeration time, the pinch valve (6) opens in two steps and the sample is
filled into a container.

Cleaning:

To clean the metering vessel (5), open the screw cap (glass) or turns to the left (plastic, bayonet
shutter), pull the silicone discharge hose to the front and remove the metering vessel.
The measuring tube (2) can be cleaned with a bottle brush BM60560 .

REMARK: The pinch valve (9) is in inoperative position always closed and will be opened 1x per

hour to avoid sticking of the silicon tube.

Replacement of dosing hose
The silicone hose (BM69301) is only pushed over the lip of the metering vessel. A hose clamp is not

required. Humidify the hose a little bit, fix it at one point and push it over the lip.

Remark: Conductivity of the sample medium

There are two conductive level electrodes in the metering vessel. Their sensitivity can
be adjusted progressively in the service menu. The factory adjusts the electrodes to
tap water (this adjustment does not have to be changed under normal operating
conditions).

Please note that a wrong adjustment can lead to a flooding of the pneumatic system and to the
damage of component parts.

ATTENTION: Wrong operating conditions can lead to malfunctions or may even damage the
apparatus. No liability or claims under guarantee will be accepted in respect of any
damage arising from the non-observance of these operating instructions.

Operation

Sample distribution at Bühler 4010/3010//6010

Ÿ Rotating distributor

- Motor-driven rotating distributor with encoder (pulse generator) which ensures:

- an exact sample discharge position as well as

- an automatic bottle position identification by means of a forked light barrier.

Remark: For reasons of operating safety, the distributor first always runs over position 1 again

when changing to the next bottle. Thus a correc t positioning even after a malfunction
(voltage loss) is always guaranteed.

Remark 2: When there are no pulses, the output is switched off and thus neither the motor

nor the gear will be damaged if the distributor is blocked.

ATTENTION: The distributor is driven by a geared motor. The distributor must under no

circumstances be turned by hand! In case of non-observance, the gear will be
damaged!

1. Description

The motor-driven distributor unit consists of a distributor tie-bar, a drive unit with motor,
a light barrier and encoder as well as a distributor head with outlet tube.
There are 2 x 10 L PE containers (or 4 x 5 L PE containers) and each container is equipped with
a discharge valve at the bottom. In addition there is a rinsing valve for each bottle at the bottom
of the inner compartment.

2. Operating elements

The red screw cap of the distributor head can be unscrewed for cleaning.

Attention: Never turn the distributor by hand (geared motor)!

3. Method of operation

- The device is typically programmed in such a way that each container is filled for a period of 24

hours. Thus, a sample of the last 24 hours is available at any time.

- At each bottle change, the distributor passes a light barrier at position 1 to synchronize.

- After having passed the light barrier, the encoder pulses of the motor are counted to position the

outlet tube on bottle 2.

- After each program-related bottle change, the new bottle is automatically emptied and rinsed.

- To do this, the distributor first moves on the respective bottle.

- Thereafter the discharge valve at the bottom of the container is opened.

- After expiration of the emptying time (adjustable), the respective rinsing valve is opened (rinsing

time is adjustable, too) and the container is rinsed.

- After rinsing, the discharge valve closes and the device is ready for sampling again.

The analog input can be calibrated in „SAMPLER

SETTINGS” ->FLOW SIGNAL. Just follow the menu
instructions.
1st step: connect 0/4 mA and confirm
2nd step: connect 20 mA and confirm
3rd step: Calibration ok, confirm

Remark: The analogue input is already calibrated to 0-20 mA in the factory.

FLOW ANALOG

The only difference between the programming of the
flow analog mode and the flow digital mode is the
definition of the sampling interval. Point of reference is
the maximum flow at 20 mA.

Event-proportional sample extraction

When selecting this sampling mode, the sampler is waiting
for an external “event” signal, e.g. from a connected pH­meter. A sample is extracted according to the programming
as long as the signal is present. When the signal is
deactivated the sampler waits for the next signal and then
fills the next empty bottle.
Which „event“ sample has been filled into which bottle
is recorded in the info memory.

In the event mode the sample extraction can be time or flow dependent. The
programming is effected as described before (sampling mode time, flow digital).

Operation

FREE PROGRAMMABLE INPUTS

Ø PROGR. INPUT
Ø ADDITIONAL INPUT 1
Ø ADDITIONAL INPUT 2
Ø ADDITIONAL INPUT 3

In the basic version 1 programmable input is available.
As an option with the "I / O expansion board" are another 3 Inputs available. Thus the sampler
can be controlled with a digital pulse (eg with external PLC).

Each INPUT (1-3) can be programmed out of the following list:

Ø NO FUNCTION

(turn off of the Input)

Ø PRG. START PULSE

(if selected, Program x will be started)

Ø PRG. STOP PULSE

(if selected, Program x will be stopped) (Back with ESC)

Ø PRG. RUN DURING PULSE

(During continuous signal, Program is running. If Signal drops down,
program stops.)

Ø DISTRIBUTOR PULSE

Pulse signal: <= 3sec means "next bottle"
>= 5 sec means "move to bottle 1"

Ø SAMPLE PULSE

Pulse means "take a sample"
Pulse signal must be > 50ms!

Remark: This feature is only available if no program is running. The unit is in
this case completely controlled externally (eg PLC)

Maintenance

Maintenance

The apparatus should be cleaned regularly in accordance with the degree of contamination present.
In view of the quality of samples, we recommend to clean thoroughly especially the wetted parts like
dosing unit, electrodes, distributor, bottles and inlet hose.

Remark:

There is a health hazard if the device is used in biologically or chemically contaminated areas. Please
take the necessary precautionary measures when cleaning or servicing the device.

Attention:

Disconnect the power connections before carrying out any maintenance or repair works. Repair works
must only be carried out by specially trained and authorised service personnel.

Remark: For cleaning of the metering vessel: see chapter „Operation – sampling systems“.

Pumping capacity: The pumping capacity (patented method) can be adjusted in the

service menu between 70 and 100 %.

Remark: The adjusted pumping capacity has no effect on the suction height

but only on the average suction speed when extracting the
sample. The lower the pumping capacity, the longer the life of the
pump

Warranty and liability

Warranty and liability

The manufacturer warrants that the product supplied is free of material and
manufacturing defects and undertakes the obligation to repair or replace any
defective parts at zero cost.
The warranty period for instruments is 24 months. If a service contract is
taken out within 6 months of purchase, the warranty period is extended to
60 months.
With the exclusion of the further claims, the supplier is liable for defects including
the lack of assured properties as follows: all those parts that, within the warranty
period calculated from the day of the transfer of risk, can be demonstrated to have
become unusable or that can only be used with significant limitations due to a
situation present prior to the transfer of risk, in particular due to incorrect design,
poor materials or inadequate finish will be improved or replaced, at the supplier's
discretion. The identification of such defects must be notified to the supplier in
writing without delay, however at the latest 7 days after the identification of the
fault. If the customer fails to notify the supplier, the product is considered approved
despite the defect. Further liability for any direct or indirect damages is not
accepted.
If instrument-specific maintenance and servicing work defined by the supplier is
to be performed within the warranty period by the customer (maintenance) or by
the supplier (servicing) and these requirem ents are not met, claims for damages
due to the failure to comply with the requirements are rendered void.
Any further claims, in particular claims for consequential damages cannot be
made.
Consumables and damage caused by improper handling, poor installation or
incorrect use are excluded from this clause.
The manufacturer process instruments are of proven reliability in many
applications and are therefore often used in automatic control loops to provide
the most economical possible operation of the related process.
To avoid or limit consequential damage, it is therefore recommended to design
the control loop such that a malfunction in an instrument results in an automatic
change over to the backup control system; this is the safest operating state for the
environment and the process.
