1 General information
The weighing platform is part of a modular system. The associated components, such as
terminals, application pacs and the extensive range of accessories, allow you to assemble a
weighing system ideally tailored to the needs of your operation.
2 Safety precautions
▲ The explosion-protected weighing platform is approved for operation in Zone 2 (gases) and
Zone 22 (dusts) hazardous areas. There is an increased danger of injuries and damage
when using the weighing platform in hazardous areas! Exercise particular care when using
in such areas. The rules for behaviour are based on the concept of "Safe Distribution"
established by METTLER TOLEDO.
▲ Explosion-protected weighing platforms may be used in hazardous areas of Zones 2 and
22 only in conjunction with weighing terminals that have the appropriate approval and interface specification.
▲ The connection cable may not be separated from the weighing terminal while it is
energised.
Selecting installation location
▲ The foundation must be capable of safely
support the weight of the weighing platform at its support points when it carries
the maximum load. At the same time, it
should be so stable that no vibrations occur during weighing operations. These requirements also apply when the weighing
platform is integrated in conveying systems and the like.
▲ Ensure that vibrations due to machines
near the installation site are kept to a
minimum.
Ambient conditions
▲ Use powder-coated/enamelled weighing platforms only in a dry environment.
▲ In a damp environment, in wet operation or when working with chemicals: use stainless-
steel or hot-galvanised weighing platforms.

3 Equipotential bonding
The equipotential bonding must be installed by a professional electrician when using the
weighing platform in Zones 2 and 22. METTLER TOLEDO Service only has a monitoring and
consulting function here.
➜ Connect equipotential bonding (PA) of all devices (weighing platform and service
terminal) in accordance with the country-specific regulations and standards. In the
process, make sure that all device housings are connected to the same potential via the
PA terminals.

4 Operating limits
The weighing platform has such a rugged design that no damage should result if the
maximum weighing capacity is occasionally exceeded.
The static load-bearing capacity, i.e. the maximum permissible load, is dependent on the type
of loading (positions A – C).

▲ Falling loads, shocks and lateral impacts
must be avoided.

▲ When travelling across recessed weigh-
ing platforms with lift trucks, ensure that
the axle load does not exceed the maximum side load (see above).
5 Cleaning the weighing platform
Maintenance of the weighing platform is limited to regular cleaning and subsequent oiling.
The procedure depends both on the type of surface (powder-coated/enamelled or stainless
steel) and on the environmental conditions prevailing at the installation location. Remove dirt
and deposits at regular intervals from the outside and inside of the weighing platform.
5.1 Notes on cleaning
DANGER
Danger of injury through shutting load plate
at KE...sk- und KES...sk weighing platforms!
▲ Only open and close the load plate with
the supplied tools!
▲ Never work under an opened unsecured
load plate!
CAUTION
Incorrect use of cleaning agents may cause damage to the weighing platform!
•Use only such cleaning agents that do not act on the plastics used in the
weighing platform.
•Be particularly careful when cleaning the measuring cell.
6
Powder-coated/enamelled version, dry
surroundings
• Wipe with a damp cloth.
• Use household cleaning agents.
Stainless-steel and hot-galvanised
versions
• Wipe with a damp cloth.
• Water jet up to 60 °C.
• Use household cleaning agents.
Corrosive surroundings
• Water jet up to 60 °C.
• Remove corrosive substances at regular
intervals.
• Only use disinfectants and cleaning
agents in accordance with the manufacturer's specifications and instructions.
Cleaning a recessed weighing platform
• Ensure gap (1) between weighing platform and pit frame is always kept clear.
• Remove larger dirt deposits at pit bottom
(2) at regular intervals.
• Check pit drainage channel (3) for
blockage at regular intervals.
7
5.2 Subsequent treatment
Carry out the following subsequent treatment in order to protect the weighing platform:
• Rinse the weighing platform with clear water.
• Dry off the weighing platform with a lint-free cloth.
• Treat the inside and outside of the weighing platform with an oil suitable for foodstuffs.
Special treatment for scales installed in the floor or a pit
• Treat all the moving parts, such as flexible bearings, knife edges and bearings, thoroughly
with an oil suitable for foodstuffs after cleaning them.
5.3 Cleaning the measuring cell
The load plate has to be removed in order to clean the measuring cell. For details please refer
to the next section.
CAUTION
The measuring cell can be damaged!
• During cleaning work, never touch, direct
an airflow against or spray the rubber
diaphragm (1) of the measuring cell.
• Blow out dirt or flush with a mediumpower water jet.

5.4 Information on removing the load plate
KC and KCS weighing platforms
• Remove the load plate by pivoting the two
side handles (1) outward.
• Replace the load plate (1) so that the
1
symbol O is located above the level indicator. Make sure that the load supports
(2) in the corners of the weighing platform are vertical.
2
K...sk weighing platforms
• Open the quick-release locks (2) with the
special key (1) and pivot up the load
plate.
CAUTION
The gas-filled springs can be damaged!
▲ Do not clean gas-filled springs with
steam jet.
▲ Do not oil the piston rod.
