Service
Regular servicing by a Sartorius
technician will extend the service life of
your Combics indicator and ensure its
continued weighing accuracy. Sartorius
can offer you service contracts, with your
choice of regular maintenance intervals
ranging from 1 month to 2 years.
The optimum maintenance interval
depends on the operating conditions at
the place of installation and on the
individual tolerance requirements.
Repairs
! Disconnect defective equipment from
power immediately (unplug the equip-
ment from the wall outlet (mains
supply)). Repairs may be performed only
by authorized Sartorius service techni-
cians using original Sartorius parts.
Repairs performed by untrained persons
may result in considerable
hazards for the user.
Important Note: If the equipment
is still under warranty, send the entire
indicator to the factory for repairs.
!
If a cable or cable gland is damaged
or defective, replace the cable as a
complete unit with all its connectors.
! Do not open the indicator while it is
carrying current. Allow at least 10 sec-
onds to elapse after disconnecting the
equipment from power before opening
the equipment housing.
Proper fitting of all surfaces is essential
for the IP rating of the housing; for this
reason the device must be opened and
closed by a certified technician.
Cleaning
! Disconnect the indicator from power
(unplug the from the wall outlet (mains
supply) and disconnect any data cables.
!
Make sure that no liquid enters the
indicator housing.
! Do not use any aggressive cleaning
agents (solvents or similar agents).
! Do not wash down the equipment
with water or dry it with compressed air;
this is not permitted.
§
Clean the indicator using a piece of
cloth which has been wet with a mild
detergent (soap).

If used in the food industry, use
a cleaning agent suitable for the parti-
cular working environment.

Care and Maintenance
$ If the weighing platform is installed in a
pit, make sure that no dirt accumulates
between the edge of the pit and the
weighing platform. This will prevent
measuring errors.
$
Observe your company’s internal
regulations and standard industry
guidelines with regard to cleaning
intervals and cleaning agents.
$
Regularly remove all dirt from the floor
of the pit.
Cleaning Stainless Steel Surfaces
Clean all stainless steel parts regularly.
Use a damp cloth or sponge to clean
stainless steel parts on the weighing
instrument. You can use any household
cleaning agent that is suitable for use
on stainless steel. Clean stainless steel
surfaces by wiping them down. Then
rinse the equipment thoroughly, making
sure to remove all residues. Afterwards,
allow the equipment to dry. If desired,
you can apply oil to the cleaned sur-
faces as additional protection.
Solvents are permitted for use only on
stainless steel parts.
Cleaning the Interior of the
Weighing Platform
$
If dirt enters the interior of the
weighing platform, the load plate
has to be removed.
Particular caution is advised when
working with models larger than
1000
+
1000 mm.
$
Blow out the interior with pressurized
air or rinse with a weak water jet
(max. 60°C).
Make sure no dirt enters the gap in the
overload safety mechanism (the gap
between the load cell and the screwed-
on plate).
Corrosive Environment
> Remove all traces of corrosive sub-
stances form the weighing platform on
a regular basis.
Replacing the Dust Cover
> Replace damaged dust covers.
§
Place the new dust cover on the
indicator and press down on the front
and back along the edges until the
cover is firmly seated.
Safety Inspection

longer ensured when:
– there is visible damage to the device
or power cord
