Operating instructions

Combics complies with the European
Council Directives as well as inter-
national regulations and standards for
electrical equipment, electromagnetic
compatibility, and the stipulated safety
requirements.
§ To prevent damage to the equipment,
read these operating instructions
thoroughly before using your Combics.
! Do not use the equipment in a
hazardous location.
! The indicator may be opened only by
authorized service technicians who
have been trained by Sartorius and who
follow Sartorius’ standard operating
procedures for maintenance and repair.
! Make absolutely sure to unplug the
indicator from power before you
connect or disconnect any electronic
peripheral devices to or from the
interface port.
! If you use electrical equipment in
installations and under ambient
conditions requiring higher safety
standards, you must comply with
the provisions as specified in the
applicable regulations for installation
in your country.
– Warning When Using Pre-wired RS-232
Connecting Cables! RS-232 cables
purchased from other manufacturers
often have incorrect pin assignments
for use with Sartorius weighing systems.
Be sure to check the pin assignments
against the chart below before
connecting the cable, and disconnect
any lines identified differently from
those specified by Sartorius.
– Use only extension cords that meet the
applicable standards and have a protec-
tive grounding conductor.
– Disconnecting the ground conductor is
prohibited!
– Note on installation:
The operator shall be responsible
for any modifications to Sartorius
equipment and must check and, if
necessary, correct these modifications.
On request, Sartorius will provide
information on the minimum operating
specifications (in accordance with
the Standards for defined immunity to
interference).
$ If there is visible damage to the
equipment or power cord: unplug the
equipment and lock it in a secure place
to ensure that it cannot be used for
the time being
Industrial protection ratings for
the housing:
– CISL models are rated to IP44
(IP65 with option L1)
– CIS models are rated to IP67
– Connect only Sartorius accessories and
options, as these are optimally designed
for use with your Combics.
– Do not expose the indicator to
aggressive chemical vapors or to
extreme temperatures, moisture,
shocks, or vibration.
– Clean your Combics only in accordance
with the cleaning instructions (see
“Care and Maintenance").
$ If you have any problems with your
Combics:
contact your local Sartorius office,
dealer or service center.
NEMA Protection rating on CIS
models:
– Protection of the indicators according
to NEMA is ensured only if the rubber
gasket is installed and all connections
are fastened securely (including the
caps on unused sockets). Weighing plat-
forms must be installed and tested by a
certified technician.
– If you install an interface port or
battery connector after setting up your
Combics, keep the protective cap(s) in
a safe place to be used for protecting
the interface port or battery connector
when not in use, or prior to shipment.
This will protect the data interface or
battery connector from vapors, moisture
and dust or dirt.
Using the Equipment in Legal
Metrology:
– When the indicator is connected to
a weighing platform and the resulting
weighing instrument is to be verified,
make sure to observe the applicable
regulations regarding verification.
Make sure to read the brochure stored
on the enclosed CD first: “Guide to
Verification of Weighing Instruments."
When connecting a Sartorius weighing
platform, make sure to observe the
permitted weighing ranges as listed in
the Declaration of Conformity.
– If any of the verification seals are
damaged, make sure to observe the
national regulations and standards
applicable in your country in such
cases. In some countries, the
verification will become null and void
and the equipment must be re-verified.
