1 Introduction
1.1 Safety instructions
General
The ICS426x weighing terminal is approved for operation in Category 2 / DIV 1 hazardous areas.
If the ICS426x weighing terminal is used in hazardous areas, special care must be taken. The code of
practice is oriented to the "Safe Distribution" concept drawn up by METTLER TOLEDO.
Competence
• The weighing system may only be installed, maintained and repaired by authorized METTLER TOLEDO
service personnel.
• The mains supply may only be installed by a specialist authorized by the owner-operator.
Ex approval
• No modifications may be made to the terminal and no repair work may be performed on the modules.
Any weighing platform or system modules that are used must comply with the specifications contained
in this manual. Non-compliant equipment jeopardizes the intrinsic safety of the system, cancels the "Ex"
approval and renders any warranty or product liability claims null and void.
• The safety of the weighing system is only guaranteed when the weighing system is operated, installed
and maintained in accordance with the respective instructions.
• Also comply with the following:
– the instructions for the system modules,
– the regulations and standards in the respective country,
– the statutory requirement for electrical equipment installed in hazardous areas in the respective
country,
– all instructions related to safety issued by the owner.
• The explosion-protected weighing system must be checked to ensure compliance with the requirements
for safety before being put into service for the first time, following any service work and every 3 years, at
least.
Operation
• Prevent the build-up of static electricity.
– Always wear suitable working clothes when operating or performing service work in a hazardous
area.
– Only use the weighing terminal when electrostatic processes leading to propagating brush
discharges are impossible.
• Prevent the build-up of dust layers.
• Do not use protective coverings for the devices.
• Avoid damage to the system components.

• Approved for Category 2 / DIV 1 hazardous areas
• Compact scale
Default equipment
The weighing terminal offers the following interfaces:
• 1 serial interface IS-RS232
• 1 scale interface (SICSpro)
Optional equipment
The weighing terminal can be equipped or retrofitted with an additional interface CL20mA to be connected to
the ACM200 interface converter in the safe area.

Straight weighing display – Bargraph
The device offers a bargraph indicating the scale capacity.
The bargraph indicates roughly which part of the scale capacity is already occupied and what capacity is
still available.
In the example above, approximately 3/4 of the scale capacity is occupied, although the applied net weight
isn’t really high. The reason therefore could be a high tare weight.
Metrological data line
The metrological data is stored in the weighing platform. The weighing terminal only serves as
indicator.

1.3 Commissioning
1.3.1 Selecting the location
The correct location is crucial for the accuracy of the weighing results.
1 Select a stable, vibration-free and, if possible, a horizontal location for
the weighing platform.
ð The ground must be able to safely bear the weight of the fully
loaded weighing platform.
2 Observe the following environmental conditions:
ð No direct sunlight
ð No strong drafts
ð No excessive temperature fluctuations
1.3.2 Leveling of weighing platforms
Only weighing platforms that have been levelled precisely horizontally,
provide accurate weighing results. Weights and Measures approved
weighing platforms have a level bubble to simplify levelling.
− Turn the adjustable feet of the weighing platform until the level bubble’s
air bubble is inside the inner circle.
For more details refer to the weighing platform documentation.

• Do not clean the weighing terminal using high-pressure or high-temperature water.
• Observe all existing regulations on cleaning intervals and permissible cleaning agents.
• Do not use compressed air or vacuum.
• Remove dust layers.
2.11 Verification test
The weighing instrument is verified if:
• the accuracy class is displayed in the metrological line,
• the approval readability is shown with "e = readability",
• it bears an official verification mark,
• the validity is not expired.
The weighing instrument is also verified if:
• the metrological line shows "Approved scale",
• labels with the metrological data are placed near the weight display,
• the securing seal is not tampered with,
• it bears an official verification mark,
• the validity is not expired.
The period of validity is country-specific. It is in the responsibility of the owner to renew verification
in due time.
