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.

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

Page 22

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 programmed. The bottle is changed at each new event signal. If an event is longer than the programmed bottle filling time, two or more bottles will be filled for this event depending on the programmed bottle filling time.

always proportional to the flow, that means: high flow = big sample volume low flow = small sample volume.

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.

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.

2. Pinch-valve closes

3. Metering vessel is filled up to the electrodes

4. Dosing system is aerated

5. Pinch valve opens and sample drains off in bottle

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.

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 .

Operation

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.

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.

Operation

Flow-proportional sample extraction

According to the output signal of your flow meter either the operating mode flow analog or flow digital can be selected in the program settings. .

IMPORTANT: If an analogue signal (0/4-20 mA)

is used, it is absolutely necessary to calibrate the input prior to the first use.

FLOW ANALOG

Calibrate the analog input 0/4-20 mA 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).

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

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.
