864 Robotic Balance Sample Processor

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭

1 Introduction

1.1 Instrument description

The 864 Robotic Balance Sample Processor is a laboratory automation sys­tem with integrated pipetting and weighing equipment. It was designed
for the fully automatic determination of TAN (Total Acid Number) and TBN
(Total Base Number) in liquids, such as e.g. petrochemical products, cool­ing oils, etc.

The basis of the system is comprised of one Sample Processor with two
towers as working stations and one multi-row sample rack which is
designed for the weighing of the sample vessels. The sample rack can
hold up to 20 liquid samples. One working station is equipped for the
pipetting of the samples, the other is equipped with titration equipment.
The weighing of the sample vessels is accomplished with an analytical bal­ance which is provided with a special weighing equipment. Three 800
Dosinos are available as dosing drives. One 809 Titrando is used for the
titrations. The rinsing and aspiration of liquids is accomplished with one
843 Pump Station in the version that has two peristaltic pump drives. The
entire system is controlled by the tiamo™ software, which contains one
high-performance database for the determination data.

1 Introduction

Mode of operation

Vessels filled with samples, as well as empty vessels and pipetting tips, are
placed on the sample rack. The rack is rotated in an automatic sequence
in such a way that one empty sample vessel on a weighing pan in the out­ermost row of the rack is pushed onto a weighing position. There it is
tared.

The robotic arm on Tower 1 takes up one of the pipetting tips, which is
kept in readiness on the innermost row of the rack. With the aid of a dos­ing drive, a defined volume of a liquid sample is aspirated into the pipet­ting tip. The content of the pipetting tip is expelled into the tared sample
vessel on the weighing position. The balance sends the weight of the
pipetted sample to the control software.

Rotation of the sample rack causes the weighed sample vessel to be trans­ported to the second processing station. There the solvent is added, stir­red and the actual determination is carried out. The sample solution is
aspirated after the titration has been completed. Electrodes and tubing
are rinsed by efficient spray nozzles. Optionally, the rinsing can take place
in an external rinsing station, which should also remove even tenacious
residues.

2.3 The Swing Head

The 786 Swing Head is an auxiliary drive for the Metrohm Sample Pro­cessor series, e.g. the 864 Robotic Balance Sample Processor. It is a high­precision motor drive that makes it possible to move to any point position
on a sample rack. Even positions outside of the sample rack are reachable
when a suitable robotic arm is used.

Two Swing Heads are already pre-installed on the 864 Robotic Balance
Sample Processor.

Left-swinging or right-swinging models are available as different types of
robotic arms. "Left-swinging" means swinging from the initial position
(pointing towards the middle of the rack) outwards to the left.

The following diagram illustrates the most important configuration data
that needs to be set in the control software to ensure correct usage of a
robotic arm (left-swinging, here).

If a Swing Head drive is mounted with a 6.2058.020 adapter in order to
use racks smaller than intended, then the axial distance must be modi­fied in the configuration of the control software. The corresponding data
can be found on the accompanying sheet of the 6.2058.020. The axial
distance refers to the distance of the swing axis (see figure) and of the axis
of rotation (middle point) of the sample rack.

2.4 Sample racks

A sample rack is a turntable that acts as a receptacle for sample vessels.
Various types of sample racks are available for different numbers and
types of sample vessels.

The 864 Robotic Balance Sample Processor requires sample racks with up
to a maximum of 48 cm diameter.

Magnet codes

Every single sample rack can be unambiguously identified by means of a
magnet code. The Sample Processor can thus recognize automatically
which rack is in place.

When replacing a rack, this should first be returned to starting position
using the Rack initialization function (see "Manual Control" in the con­trol software). This will enable an unambiguous recognition of the rack

3.17 Adjusting the rack and the robotic arm

For picking up pipetting tips the adapter must be precisely positioned on
the robotic arm. In order to ensure this, it is necessary to align the sample
rack and the robotic arm precisely in relation to one another. The control
software tiamo™ allows the user to enter an offset in both robotic arm
and sample rack (rack table) configuration. This allows fine tuning to be
performed.

￭￭￭￭￭￭￭￭

3.18 Adjusting the weighing equipment

The weighing equipment must be precisely adjusted in order to ensure a
problem-free weighing of the sample vessels. To weigh a sample, the
sample vessel is moved ahead of Tower 1, i.e. the rack is rotated until the
sample vessel is standing on the weighing plunger with the weighing pan.
The weighing plunger must lift off the sample vessel from the rack with
the weighing pan. Both the vessel and the weighing pan must be free­standing and are not permitted to touch the rack during the weighing.

In order to ensure that the prerequisites outlined above are in effect, the
horizontal position of the weighing plunger must be centered precisely to
the sample position of the rack. The vertical position of the weighing
plunger must be adjusted in such a way that the sample vessel is lifted off
sufficiently.

3.21 Connecting MSB devices

In order to connect MSB devices, e.g. stirrers or dosing devices, Metrohm
instruments are equipped with up a maximum of four connectors at what
is referred to as the Metrohm Serial Bus (MSB). Various kinds of peripheral
devices can be connected in sequence (in series, as a "daisy chain") at a
single MSB connector (8-pin Mini DIN socket) and controlled simultane­ously by the respective control instrument. In addition to the connection
cable, stirrers and the remote box are each equipped with their own MSB
socket for this purpose.

3 Installation

The following illustration provides an overview of the devices that can be
connected to an MSB socket, along with a number of different cabling
variations.

The question of which peripheral devices are supported depends on the
control instrument.

Note

When connecting MSB devices together, the following must be
observed:

￭ Only one device of the same type can be used at a single MSB con-

nector at one time.

￭ Type 700 Dosino and 685 Dosimat dosing devices cannot be con-

nected together with other MSB instruments on a shared connector.
These dosing devices must be connected separately.

864 Robotic Balance Sample Processor

￭￭￭￭￭￭￭￭

59

3.21 Connecting MSB devices

Caution

Exit the control software before you plug MSB instruments in. The con­trol instrument recognizes when it is switched on which instrument is
connected at which MSB connector. The operating unit or the control
software enters the connected MSB devices into the system configura­tion (Device manager).

MSB connections can be extended with the 6.2151.010 cable. The length
of the connection must not exceed a maximum of 15 m.

3.21.1 Connecting dosing devices

Three dosing devices can be connected to the instrument.

The types of dosing devices that are supported are:

￭ 800 Dosino
￭ 700 Dosino
￭ 805 Dosimat
￭ 685 Dosimat

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭

Warning

If a Dosino is connected to the 864 Robotic Balance Sample Processor,
then the connection cable must be equipped with a ferrite core
T.2400.102. The ferrite core reduces any interference voltages that may
occur and thus ensures compliance with strict EMC standards pursuant
to applicable technical norms, see Chapter "Technical Data".

Proceed as follows:

1

Mounting ferrite core

Fasten a ferrite core T.2400.102 to the Dosino connection cable near
to the plug.

2

Connect a dosing device

￭ Exit the control software.
￭ Connect the connection cable to one of the sockets marked with

MSB on the rear of the control instrument.

Figure 40 Rod Stirrer and titration stand

Note

If an MSB stirrer is connected to the MSB1 socket, then the stirrer con­nector at Tower 1 cannot be used, because both sockets are controlled
internally via MSB1. This also applies to the MSB2 socket and the stirrer
connector on Tower 2 for 2-tower models of USB Sample Processors.

3.21.3 Connecting a remote box

Instruments that are controlled via remote lines and/or which send control
signals via remote lines can be connected using the 6.2148.010 remote
box. In addition to Metrohm, other instrument manufacturers also use
similar connectors that make it possible to connect different instruments
together. These interfaces are also frequently given the designations "TTL
Logic", "I/O Control" or "Relay Control" and generally have a signal level
of 5 volts.

Control signals are understood to be electrical line statuses or brief
(> 200 ms) electrical pulses which display the operational state of an
instrument or which trigger or report an event. Sequences on a variety of
instruments can thus be coordinated in a single complex automation sys­tem. No exchange of data is possible, however.

Proceed as follows:

1

Connect a remote box

￭ Exit the control software.
￭ Connect the remote box connection cable to one of the sockets

marked with MSB on the rear of the control instrument.

￭ Start the control software.

You can, for example, connect an 849 Level Control Box (fill level monitor
in a waste canister) or a 731 Relay Box (switch box for 230/110 volt alter­nating current sockets and low-voltage direct current outlets). The remote
box also has an MSB socket at which a further MSB instrument, e.g. a
dosing device or a stirrer, can be connected.

You will find precise information concerning the pin assignment of the
interface on the remote box in Appendix (see Chapter 6.1, page 69).

3.22 Connecting USB devices

Two USB connectors (Type A sockets) are available for connecting devices
with USB interfaces. The 864 Robotic Balance Sample Processor functions
then as a USB hub (distributor). If you wish to connect more than two USB
devices, you can also use an additional commercially available USB hub.

3 Installation

Note

When a USB device is connected, the control instrument recognizes
which device is connected. The control software automatically enters a
connected USB device into the system configuration (Device manager).

3.22.1 Connecting a barcode reader

A barcode reader is used as an input aid for entering text and numbers.
You can connect a barcode reader to a USB interface.

Connect a barcode reader as follows:

Configuring the barcode reader in the control software

￭ Configure the barcode reader in the configuration part of the

control software as described in the online Software Help.

Settings of the barcode reader

The barcode reader requires certain basic settings. You will find directions
in the Instructions for Use as to how you can program the barcode reader.
Switch the barcode reader to programming mode and make the following
settings:

￭ Select the keyboard layout for the desired country (USA, Ger-

1

many, France, Spain, Switzerland (German)). This setting must
match the setting in the control software.

￭ Make sure that the Ctrl characters (ASCII 00 to 31) are allowed to

be sent.

￭ Adjust the settings so that the ASCII character 02 (STX or Ctrl B) is

sent as the first character as "Preamble" or "Prefix Code".

￭ Adjust the settings so that the ASCII character 04 (EOT or Ctrl D) is

sent as the last character as "Postamble" or "Record Suffix" or
"Postfix Code".

￭ Exit programming mode.

4 Handling and maintenance

4.1 General

The 864 Robotic Balance Sample Processor requires appropriate care.
Excess contamination of the instrument may result in functional disrup­tions and a reduction in the service life of the sturdy mechanics and elec­tronics of the instrument.

Severe contamination can also have an influence on the measured results.
Regular cleaning of exposed parts can prevent this to a large extent.

Spilled chemicals and solvents must be removed immediately. In particular,
the mains plug should be protected from contamination.

4.2 Care

4 Handling and maintenance

￭ Check all tubing connections regularly for leaks.
￭ Flush out the tubing connections from time to time. The tubings must

be replaced after prolonged usage.
