Each tower of the 717 Sample
Changer is equipped with a
beaker indicator to detect the
presence of a beaker in front
of the particular tower. This
infrared sensor detects many
different materials, if any object is placed in correct position.

The magnetic sensor to detect
the individual rack codes is
mounted below the sample
changer's turntable.
The 717 Sample Changer
should be initialized right after
every rack change, because the
magnetic binary code of the
racks can only be read, if the
rack is in initial position and
therefore the magnet holder is
in accurate position right above
the rack code indicator.

2 Installation
2.1 Setting up the Instrument
Packaging
The 717 Sample Changer is supplied with the accessories in
separate special packages designed to ensure maximum protection. These contain shock-absorbing foam linings. As only these
special packages guarantee damage-free transport of the instrument, it is essential you store them in a safe place.
Control
Immediately following delivery, check that the consignment is
complete and undamaged (compare with delivery note and accessories list, page 29ff). In case of damage, see "Warranty",
page 24.
2.1 Setting up the Instrument
Setting up
The 717 Sample Changer is a rugged instrument and may be
used in rough environments such as laboratories and manufacturing plants. It must not be exposed to a corrosive atmosphere.
If the sample changer is operated in a rough environment, regular
maintenance is strongly recommended.
717 Sample Changer, Installation

2.2 Safety Considerations
2.2 Safety Considerations
If failure or malfunctioning occurs during operation of the
717 Sample Changer, the Metrohm Service Department should be
consulted.
If opening the instrument is unavoidable, the following safety precautions are to be strictly adhered to:
Before opening the instrument disconnect it from all electrical sources. Make sure that all main cables have been disconnected.
Only in exceptional cases should the instrument be opened while it
is switched on. Because parts that conduct current are exposed in
this case, this should only be undertaken by an expert who is acquainted with the associated dangers.
Electronic components are sensitive to static electricity and can be
destroyed by discharge. Before touching any components inside
the instrument, both the person and his tools should be grounded
by grasping a grounded object (for example: a metallic part of the
casing of the instrument or a radiator) in order to eliminate any
static electricity.
When peripheral instruments are connected to the 717 Sample
Changer, the sample changer and the instruments to be connected have to be switched off, otherwise all instruments could
suffer damage.
If it becomes apparent that the instrument can no longer be operated safely, it must be put out of operation.

717 Sample Changer, Installation
2.3 Arranging the Accessories
2.3.1 Setting up the Rinsing Equipment
To mount the PTFE tubings to the pump inlets or outlets enlarge it
carefully using a screwdriver, a pen or another appropriate tool. A
piece of sand paper facilitates grasping of the tubing.
The arrangement of the tubing depends on the rinsing equipment.
Rotating nozzle
Using a changer model with one pump per tower only, the rotating
nozzle (6.2740.000) is recommended for rinsing. The Teflon tubing
is then directly connected to the rinsing pump (pump 1). The distribution head may be dismounted in this case.
2.3 Arranging the Accessories
Place the rotating nozzle vertically in the titration head with the aid
of a SGJ14/12 mm sleeve.
Spray nozzles
When using a changer model with two pumps per tower, spray
nozzles (6.2740.020) may be used in combination with an aspiration tip M8 (6.1543.170). Insert the spray nozzles into the sloped
borings of the titration head. Use Teflon tubings to connect them
to the distribution head. Each of the four outlets of the distribution
head must be plugged. Plug unused outlets with an M6 thread
stopper (6.1446.040) to avoid splashing of liquid during rinsing.
Fix the tubings in the guide chain. Chain links may be removed if
necessary (see below).
Insert the aspiration tip vertically into a boring (SGJ9) of the Macro
Titration head. The Micro Titration head offers also a vertical boring for the placement of the aspiration tip. Connect the tip with the
Teflon 4/6 tubing (6.1805.510) and a screw connector 4/6 mm
(6.1820.030) to pump 2 (valve marked with 'ê'). During the rinsing
procedure, first the sample is sucked off then the electrode is
rinsed in the empty vessel.
717 Sample Changer, Installation
7
2.3 Arranging the Accessories
The pump heads of the diaphragm pump, the fittings and the coupling rings are made of PVDF. PVDF is resistant to many chemicals. Acetone, acetanhydride or dimethylformamide (DMF) should
not be used. The diaphragm, and the inner parts of the valves
consist of PTFE and are resistant to most chemicals.
If your samples contain solids (e.g. silver chloride) or sticking substances, you should use the 772 Peristaltic Pump Unit in combination with the 731 Relay Box instead of the diaphragm pump integrated into the changer.
The PE canisters (6.1621.000) are suitable for aqueous solutions.
2.3.2 Tubing Fixation
In order to fix the tubing in
the guide chain any chain link
may be opened with a screw
driver or another appropriate
tool.

3 Sample Racks
3 Sample Racks
A sample rack is a sort of turntable for the positioning of beakers
which are to be placed on the 717 Sample Changer. Because for
titration, various sizes of beakers are common or required, many
kinds of racks can be used and are easily interchangeable. The
rack offers space for various numbers of samples depending on
the diameter of the beakers. Metrohm delivers the following predefined types of standard racks:
Type Number of
beakers

If desired, other user-defined racks can be delivered. Irregular arrangements of beaker positions are also possible.
Every single rack can be identified by a unique magnetic code.
Rod magnets which are attached to the bottom of the rack can be
combined to form a 6-place binary code. The sample changer can
then automatically recognize the mounted rack. This is possible
when the rack is positioned with the first rack position in front of
tower 1. When changing a rack, the sample changer should first
be reset to the normal position. This way the save recognition of a
rack and therefore the correct beaker positioning is made possible. An internal position table containing the unambiguous definition of the turning angles and beaker positions is assigned to each
rack type.
This position table is stored in the control device.

The standard racks provided by Metrohm are already equipped
with a predefined magnetic code for every rack type. If several
racks of the same type are used, the magnet rods can be arranged differently so that a unique identification of a sample rack
is possible, if this is desired.
Format of a magnetic code (example):
000001 i.e. only one magnet is inserted, bit 0
000101 i.e. two magnets are inserted, bit 0 and 2
63 different combinations are possible. The code 000000 stands
for "no code defined".

4.1 Prerequisites
4 Swing Head
To ensure that the individual vessels are approached with precision even when using multiple-row sample racks, a 759 Swing
Head can be installed instead of the normal titration head. The
swing head is fitted with either a titration head (2.759.0020) or a
transfer head (2.759.0010) for pipetting the sample from the sample vessel into a bigger titrating vessel.
4.1 Prerequisites
The 759 Swing Head can be used in combination with the following racks:
Sample rack 759 model Number of
towers
Titration 48 x 75 mL for direct titration
Article No. 6.2041.350
Pipetting 126 x 15 mL and
2 x 150 mL for pipetting
Article No. 6.2041.400
If the two-row sample rack with 48 beakers is used on the 2-tower
model for direct titration, sample beakers cannot be approached
with tower 2. If the rack is used for transferring samples from 126
test tubes into two central measuring/rinsing vessels (special
beakers), all the positions can be approached with tower 1,
whereas tower 2 can only approach the two special beakers.
The swing head cannot be used in combination with other standard rack types.
4.2 Installing the Swing Head
The best procedure for installing the swing head is described below. The swing head will normally be installed by our service personnel.
If a 2-tower sample changer is used, the swing head must always be connected to tower 1 (see page 4)!

Aligning the titration/transfer head
The swing head executes a shift movement as it approaches the
sample vessels. It can adopt any of four fixed positions, depending
on which row is targeted, or whether the lift is in the shift position.
The titration or transfer head should be aligned in order to guarantee that the individual positions are approached with precision.
Place the sample rack that you wish to use on the sample changer
and insert a few sample vessels. Approach one sample position.
Slightly loosen the three screws securing the titration head to the
underside of the swing head and align the titration head so that
electrodes, stirrer, burette tip and tubes are centered in the sample vessel. Retighten the screws. Proceed in exactly the same way
for the transfer head.

717 Sample Changer, Appendix
5.2 Servicing and Maintenance
5.2.1 Servicing
The maintenance of the 717 Sample Changer should include a
yearly service check carried out by a specialist from Metrohm. If
caustic or corrosive chemicals are frequently used, shorter time
intervals between service checks can be necessary.
The Metrohm Service Department can offer technical advice regarding servicing and maintenance of all Metrohm instruments at
any time.
5.2.2 Maintenance / Attendance
Not only do highly sensitive measuring instruments require proper
care, a sample changer also requires this. Serious contaminations
can lead to functional disorders and a shortened life-span of the
rugged mechanics and electronics of the sample changer.
5.2 Servicing and Maintenance
Heavy soiling of the titration heads can influence the results of
measurements. Regular cleaning of exposed parts can prevent
this for the most part.
Chemical or solvent spills should be cleaned up immediately. The
connectors (in particular the power supply) should be protected
from contamination. The sample changer should never be operated without the covering foreseen for this purpose.
If corrosive media has entered the inside of the instrument, the
power plug has to be disconnected immediately to avoid massive
damage to the instruments electronic components. In case of such
damage, the Metrohm service personnel should be notified.
The instrument should not be opened by untrained personnel.

ered by the warranty. Checks which are not a result of material or
manufacturing faults are also charged during the warranty period.
For parts of outside manufacture insofar as these constitute an
appreciable part of our instrument, the warranty stipulations of the
manufacturer in question apply.
With the regard to the guarantee of accuracy, the technical specifications in the instruction manual are authoritative.
Concerning defects in material, construction or design as well as
the absence of guaranteed features, the orderer has no rights or
claims except those mentioned above.
If damage of the packaging is evident on receipt of a consignment
or if the goods show signs of transport damage after unpacking,
the carrier must be informed immediately and a written damage
report demanded. lack of an official damage report releases
Metrohm from any liability to pay compensation.
If any instruments and parts have to be returned, the original
packaging should be used if at all possible. This applies above all
to instruments, electrodes, burette cylinders and PTFE pistons.
Before embedment in wood shavings or similar material, the parts
must be packed in a dustproof package (for instruments, use of a
plastic bag is imperative). If open assemblies are enclosed in the
scope of delivery that are sensitive to electromagnetic voltages
(e.g. data interfaces etc.) these must be returned in the associated
original protective packaging (e.g. conductive protective bag).
(Exception: assemblies with built-in voltage source belong in a
non-conductive protective packaging). For damage which arises
as a result of non-compliance with these instructions, no warranty
responsibility whatsoever will be accepted by Metrohm.
