Installation

Installing the apparatus

- We recommend to install the apparatus as close to the sampling point as possible. If installed

outside, the device should be positioned on a solid flat surface.

- The hose has to be laid with a constant fall from the sampler to the sampling point as lower

lying points can lead to deposits in the hose which may freeze in winter or result in crosscontaminations.

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

- Immerse the end of the hose at the sampling point with the open end facing downstream

(direction of flow) so that coarse matter and fibres cannot be forced into the suction aperture

Mains connection / external power supply

A battery charger (option) is available to charge the battery.

Mains powered float charge option

The integral storage battery can be charged by means of the mains powered battery charger. In case of a higher energy demand, the battery charger can be permanently connected to the mains, so that the integral storage battery of the sampler is left permanently on charge (float charge).

Integral storage battery

A fully charged battery will, under ideal conditions, be sufficient for up to 2000 sample extractions.

Charging the storage battery

The integral battery is a maintenance-free sealed lead-acid battery. Charge the storage battery for at least 14 -16 hours prior to the first use. This charging time is also necessary if the storage battery is empty. To avoid a total discharge, a protective mechanism is built-in which automatically switches off the device when the voltage is too low. The storage battery cannot be overcharged as the battery charger switches to compensation charge as soon as the battery is fully charged. For longer periods of non-use, top up the charge regularly (connect the battery to the charger). In any case, avoid a total discharge as otherwise the storage battery will be damaged.

Switch on / off

The device is switched on and off by the ON / OFF switch. Option: mains operation. In case of exclusive mains operation, the device is switched on by means of the mains plug of the battery charger.

Hose connection

The inlet hose is connected at the side of the housing upper part (screw thread ¾“).

Signal connections The signal connector (e.g. for a flow meter) is in front of the control.

Connection to a PC

The sampler is connected to a PC by means of an interface cable (art. No. BM900021) which is connected to the RS232 connector.

Flow graph

Timeproportional

Flowdependent

Event signal

Eventproportional

A sample is extracted in fixed time intervals (e.g. every 10 minutes) with a fixed sample volume (e.g. 50 ml).

A sample is extracted in variable time intervals (depending on the flow (Q)) with a fixed sample volume.

The sampler is waiting for an event (e.g. the exceeding of a pH limit value). A sample is extracted in fixed time intervals (e.g. every 10 minutes) with a fixed volume (e.g. 50 ml) as long as an event is present.

Page 17 Manual BÜHLER 2000/1029

Page 18

Operation

Sampling modes

The following sampling modes can be programmed:

Sampling mode Description Example Time-proportional In this sampling mode, the single

sample extractions as well as the bottle change are effected in fixed time intervals.

Flow-dependent

- digital

Flow-dependent

- analogue

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

Event-proportional 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 is 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.

Sampling system

Vacuum sampling system Metering vessel -structure-

1. Hose connector

2. Flange

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 19 Manual BÜHLER 2000/1029

Page 20

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.

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

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

**********************

2. Programming of a „FLOW-DEPENDENT“ sampling program

If this sampling mode is selected, the sampler has to be connected to a flow meter which either supplies an analogue signal (0/4 - 20mA) or a digital pulse. The sample extraction is carried out according to this „flow signal“. The programming of each of the three modes (0 -20 / 4 - 20 / digital) is very similar. Only single menus are different (depending on the selected settings). The programming of these menus is depending on the context and thus results from it accordingly.

The following example shows the programming of:

- Flow analogue 0 - 20mA /time-related bottle filling / max. number of samples per bottle limited.

Limitation of suction time. After expiration of this time, the suction process is terminated even if no water has been drawn off, that means that there was no signal from the level electrodes. If this is the case, a second attempt is made. That means after expiration of the suction time, the line is purged again and water is drawn off. If this second attempt fails, too, the message „ERROR SUCTION“ is displayed which is resulting in a malfunction message (utilizable signal if an optional relay is installed).

However, the sampler continues to function even after a malfunction message. The program is not aborted for that reason!

Possibility to correct the return time of the valve if it does not stand straight. This is important for the pinch-valve to close correctly during a sample extraction.

The pinch-valve first only opens 1/3. Here you can input the time until it opens completely. This is recommended if distributor variants are installed, as the biggest part of the sample drains off more slowly. Apart from that, the sample is discharged more gently.

Adjust the sensitivity of the conductivity electrodes.

However, this value has no dimension!

Make sure that the system is neither adjusted too insensitive (leads to a flooding) nor too sensitive (there is a permanent signal and thus no more sample extraction). A lower value (e.g. 200) means more sensitive or quicker response of the electrodes. A higher value (e.g. 300) means more insensitive or slower response of the electrodes.

Adjust the pumping capacity in % The adjusted pumping capacity does not influence the suction

height but only the average suction speed when drawing-off the sample. The lower the pumping capacity, the longer the service life of the pump.

Adjust the pinch-valve power in %.

ADJUST TIME FOR CHANGE TO BOTTLE 1 With this function a fixed allocation between bottle number and

time of the day is achieved! The program start is possible at any time, but with the condition that the sampler changes into a 24-hour cycle with bottle No. 1 at a desired time. Contrary to the delayed program start, the sample extraction is started immediately after the program start.

Remark:

This function is recommended if a program repeat has been programmed as the change to bottle No. 1 after the program start is always effected at the entered time in a 24-hour rhythm. If the program has been started without program repeat, the bottle change is effected as described and the program is terminated after 12 bottles have been filled.

**********************

Example:

• Program settings:

- Start time of first bottle: 00:00 h

- Bottle change: 2 hours

- Number of bottles: 12 bottles If the function „Start time 1st bottle“ has been chosen and the program is e.g. started at 08.30 h (= real time), the program flow is as follows:

1st step: Distributor synchronizes to bottle No. 1. 2nd step: By way of calculation the program start is effected in the past, at the time entered in

the menu (that is 00.00 h). Thus the program is immediately in the desired 24-hour cycle.

3rd step: Proceeding from the current time (08:30 h), the sampler now automatically

calculates the bottle/distributor position on which the sample extraction has to be started in reality in order to ensure the bottle change to bottle No. 1 at 00:00 h.

4th step: The distributor moves to the calculated bottle position (according to our example

bottle No. 5) 5th step: The sample extraction is started with this bottle. According to our example, the sample extraction would be started at 8:30 h with bottle No. 5. Bottle No. 5 would be filled for further 1,5 hours.

Enter a sampling pause between the single bottles. Example: -Number of bottles 12

-Filling time 60 min.

-Sampling pause 60 min. After the program has been started, samples are filled into the first bottle for a period of 60 min. Then the program is interrupted for 1 hour (=sampling pause).

**********************

COMBINED EVENT SAMPLING This function enables an overriding event-related sample extraction independent of the previously programmed sampling modes TIME or FLOW. An event can e.g. be that a limit value (pH) is exceeded. The pH measuring instrument thus delivers the signal necessary for the sampler to change to the event-related sampling mode!

Example: You have started a time-proportional program according to which a sample is extracted every 10 minutes. If the combined event-dependent sampling mode has been activated and the device receives an event pulse, the distributor immediately changes to the next (empty) bottle and the event-dependent sample extraction is started. The event sampling is carried out according to the adjusted parameters: „Interval combined event sampling“ and „Bottle filling time comb. event sampling“.

According to the example this would mean:

Sampling interval: 3minutes Filling time per event bottle: 1 hour

The sampler extracts samples according to these parameters until the event signal is released. Then the sampler continues to carry out sample extractions according to the previously selected sampling mode!

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

service menu between 20 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 requirements 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.
