3.3 Connecting MSB devices
In order to connect MSB devices, e.g. stirrers or dosing devices, Metrohm
instruments are equipped with up to a maximum of four connectors on
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 figure provides an overview of the instruments that can be
connected to an MSB socket, along with a number of different cabling
variations.

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.
CAUTION
Exit the control software before you plug in MSB instruments. When it
is switched on, the control instrument automatically recognizes which
device is connected to 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 maximum connection length permitted is 15 m.
3.3.1 Connecting a dosing device
Four dosing devices can be connected to the instrument (MSB 1 to MSB

3.3.3 Connecting a Remote Box
Instruments that are controlled via remote lines and/or that send control
signals via remote lines can be connected via 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 electrical
pulses (> 200 ms) which display the operating status 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:

disrupted by electrostatic and electromagnetic fields in media with low
conductivity. Use our 6.0229.100 Solvotrode or other special electrodes
for pH measurements in organic solvents. If no reliable measurements are
possible with these, then a 6.5104.030 (230 V) or 6.5104.040 (115 V) differential amplifier can be used. The differential amplifier is connected to
the high-ohm measuring input (Ind.).

4 Setting up the titration vessel
4.1 General
During the titration, it is important that the solution be well-mixed. The
stirring rate should be high enough for a small "vortex" to appear. If the
stirring rate is too high, then air bubbles will be aspirated. This results in
incorrect measured values. If the stirring rate is too low, then the solution
at the electrode will not be correctly mixed. In order to ensure that measurement is carried out in a well-mixed solution following addition of the
titrant, the buret tip should be placed in a position where the turbulence is
high. In addition, the distance between the addition of the titrant and the
electrode should be as large as possible. Also take into account the stirring
direction (counterclockwise or clockwise) when positioning electrode and
buret tip (see figure below).

5 Operation and maintenance
5.1 General notes
5.1.1 Care
The 902 Titrando requires appropriate care. Excess contamination of the
instrument may result in functional disruptions and a reduction in the service life of the otherwise sturdy mechanics and electronics.
Spilled chemicals and solvents should be removed immediately. Above all,
the plug connections on the rear of the instrument (in particular the
power socket) should be protected from contamination.
CAUTION
Although this is largely prevented by design measures, the power plug
should be unplugged immediately if aggressive media have found their
way into the interior of the instrument to prevent serious damage to
the instrument electronics. In such cases, Metrohm Service must be
informed.
5 Operation and maintenance
5.1.2 Maintenance by Metrohm Service

9 Warranty (guarantee)
Metrohm guarantees that the deliveries and services it provides are free of
defects in materials, design or manufacturing.
The general warranty period is 36 months (exclusions below) from the
date of delivery, or 18 months in the event of continuous operation. The
warranty remains valid on the condition that the servicing is provided by a
service organization authorized by Metrohm at defined intervals and with
a defined scope.
The warranty period for anion suppressors of the type "MSM" is 120
months from the date of delivery or 60 months in the case of continuous
operation.
The warranty period for IC separation columns is 90 days after start-up.
For third-party components that are recognizable as such, the manufacturer's warranty regulations apply.
9 Warranty (guarantee)
For instruments sold under the Metrohm NIRSystems brand, a full 16month warranty is applicable. In the event of continuous operation, the
warranty period is reduced by half.
Consumables and materials with limited storage life and glass breakage in
the case of electrodes or other glass parts are excluded from the warranty.
Warranty claims cannot be asserted if the ordering party has failed to
meet its payment obligations according to schedule.
During the warranty period, Metrohm undertakes either to replace free of
charge or to credit the purchaser for any modules or components that can
be shown to be faulty. Any transport or customs fees that may apply are
the responsibility of the ordering party.
The precondition for this is that the ordering party has to specify the article number, the article designation, an adequate error description, the
delivery date and (if applicable) the serial number or chip data in the Support Tracker. Metrohm then decides whether a replacement or a credit
note is to be issued or whether the faulty part has to be returned using
the Return Material Authorization (RMA). If a replacement or credit note is
issued, the ordering party undertakes to store the faulty part for at least
24 months in accordance with the current storage directives (in compliance with ESD guidelines) and to hold it in readiness for onsite inspection
or for return shipment to Metrohm. Metrohm reserves the right to invoice
the ordering party for these articles, including retroactively, in the event of
noncompliance with these preconditions.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
The same warranty periods that are specified for a corresponding new
part apply to parts that are replaced or repaired within the above-mentioned warranty periods. However, replacement or repair of a part does
not extend the warranty period of the entire system.
Deficiencies arising from circumstances that are not the responsibility of
Metrohm, such as improper storage or improper use, etc., are expressly
excluded from the warranty.
Metrohm also offers a 120-month spare parts availability guarantee and a
60-month PC software support warranty, calculated from the date on
which the product is withdrawn from the market. The content of this warranty is the ability of the customer to obtain functioning spare parts or
appropriate software support at market prices during the time of the warranty period. This does not apply for software products sold under the
Metrohm NIRSystems brand.
If Metrohm AG is unable to meet this obligation due to circumstances
beyond the control of Metrohm AG, then the ordering party shall be
offered alternative solutions at preferential conditions.
