1 Introduction
1.1 Instrument description
The 786 Swing Head is an auxiliary drive for the Sample Processors from
Metrohm, e.g. the 815 USB Robotic Sample Processor XL. It extends the
capabilities
precisely to any given position on a sample rack. The working area of the
Sample Processors is now being expanded even further. Now, even positions
outside of the sample rack can be moved to as a result. It is thus possible to
transfer samples from the sample rack into separate working stations in just
a few simple steps.
This is a high-precision motor drive, which is mounted on the tower of a
Sample Processor. Robotic arms of different construction types are available
for assembly on the 786 Swing Head. Equipped with the corresponding
accessories, these can be used for applications requiring a high degree of
flexibility or very complex working steps.

Warning
This instrument may only be operated in accordance with the specifications in this documentation.
1 Introduction
Warning
This symbol draws attention to a possible biological
hazard.
Caution
This symbol draws attention to a possible damage of
instruments or instrument parts.
Note
This symbol marks additional information and tips.
This instrument has left the factory in a flawless state in terms of technical
safety. To maintain this state and ensure non-hazardous operation of the

1.5.3 Tubing and capillary connections
Caution
Leaks in tubing and capillary connections are a safety risk. Tighten all
connections well by hand. Avoid applying excessive force to tubing connections. Damaged tubing ends lead to leakage. Appropriate tools can
be used to loosen connections.
Check the connections regularly for leakage. If the instrument is used
mainly
in unattended operation, then weekly inspections are mandatory.
1.5.4 Personnel safety
Warning
Wear protective goggles and working clothes suitable for laboratory work
while operating the 786 Swing Head. It is also advisable to wear gloves
when caustic liquids are used or in situations where glass vessels could
break.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Warning
Always install the safety shield supplied with the equipment before using
the instrument for the first time. Pre-installed safety shields are not
allowed to be removed.
The 786 Swing Head may not be operated without a safety shield!
Warning
Personnel are not permitted to reach into the working area of the instrument while operations are running!
A considerable risk of injury exists for the user.
Warning
In the event of a possible blockage of a drive, the mains plug must be
pulled out of the socket immediately. Do not attempt to free jammed
sample vessels or other parts while the device is switched on. Blockages
can only be cleared when the instrument is in a voltage-free status; this
action generally involves a considerable risk of injury.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Caution
Take care to ensure when mounting tubing and cables that there is no
traction on the drives while moving the lift or swiveling the robotic arm.
This could lead to overloading of and possible damage to the drive.
Remove
the clips of the two lowest chain links when you install the rinsing
and aspiration tubing.
3.3.3 Mounting the robotic arm reinforcement
In cases in which it is necessary to take up or strip off a filter or a pipetting
tip on the robotic arm, you must mount a 6.2058.090 robotic arm rein-
forcement. The reinforcement provides the robotic arm with stable resistance when picking up or stripping the tools used and prevents it from
bending.
The reinforcement has to be placed before mounting a robotic arm. Proceed
as follows:

3.4 Configuring the robotic arm
A variety of differently constructed robotic arms is available for enabling a
range of applications. They differ from one another in their geometric
wide
sizes, e.g. swing radius or maximum permissible swing angle. The configuration data must be entered in the Sample Processor or in the control
software prior to the assembly of the robotic arm. The data required
is engraved on the underside of the robotic arm. Examples of the most
common robotic arms are shown in the illustration below.

means swinging from the initial position (pointing towards the middle of the
rack) outwards to the left.
In
the case of a Sample Processor with two towers, a right-swinging robotic
arm must be mounted on Tower 1, a left-swinging robotic arm on Tower 2.
If the alignment is incorrect, the two robotic arms could possibly come into
contact with one another, resulting in damage to the drives.
3.5 Mounting the robotic arm
Depending on the model, robotic arms can be mounted as either rightswinging or left-swinging. The position of the limitation screw of the robotic
arm must be taken into account during assembly. The limitation screw must
face the tower of the Sample Processor during the mounting of the robotic
arm. The following illustration shows on the left the position of the limitation
screw at a right-swinging robotic arm (Position 1) and on the right with a
left-swinging robotic arm (Position 2).
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
Figure 10 Limitation screw at the robotic arm
For robotic arms which can be mounted in two different ways (e.g.
6.1462.050), the limitation screw can be fitted in accordance with the
required assembly direction (see above).
Note
The configuration data of a robotic arm must be configured in the control
software before it is mounted (see Chapter 3.4, page 13).
Mounting the robotic arm
The mounting of a robotic arm on the Swing Head is described here, taking
as an example a 6.1462.070 robotic arm for titration and a 6.1458.040
titration head insert. Initialize the Sample Processor before performing the
mounting sequence.
After the initialization of the Sample Processor, the drive disc of the Swing
Head
is positioned as though the robotic arm were located in the outermost
position.

Functioning of the beaker sensor
If the beaker sensor of the robotic arm is activated, then the lift of the Sample
Processor will move automatically into its work position after a MOVE command. The presence of the sample vessel is checked by the robotic arm
setting down on top of it.

No separate LIFT command is required in such cases.
Note
The work position of the lift must be configured in such a way that the
robotic arm is in place on the sample vessel. The robotic arm must bend
slightly while doing so, so that the Piezo sensor will generate a signal.

4 Handling and maintenance
4.1 General
The
786 Swing Head 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.
4.2 Quality Management and validation with Metrohm
Quality Management
Metrohm offers you comprehensive support in implementing quality management measures for instruments and software. Further information on
this can be found in the brochure «Quality Management with
Metrohm» available from your local Metrohm agent.
Validation
Please contact your local Metrohm agent for support in validating instruments and software. Here you can also obtain validation documentation to
provide help for carrying out the Installation Qualification (IQ) and the
Operational Qualification (OQ). IQ and OQ are also offered as a service
by the Metrohm agents. In addition, various application bulletins are also
available on the subject, which also contain Standard Operating Proce-
dures (SOP) for testing analytical measuring instruments for reproducibility
and correctness.
Maintenance
Electronic and mechanical functional groups in Metrohm instruments can
and should be checked as part of regular maintenance by specialist personnel from Metrohm. Please ask your local Metrohm agent regarding the
precise terms and conditions involved in concluding a corresponding maintenance agreement.
Note
You can find information on the subjects of quality management, valida-
and maintenance as well as an overview of the documents currently
tion
available at www.metrohm.com/com/ under Support.
