safety-related notifications. The locations of these labels are given in the drawings supplied with your
equipment. There are three types of safety labels:
•Hazard notifications
•Mandatory procedures
•Prohibitive procedures
Additionally, NOTICE labels may appear on your equipment.
The meanings of the different kinds of labels are explained in the following sections.
Before you transport, install, operate or work on the equipment, find out about the location and meanings of
the labels. Maintain the labels so that they are clear of obstructions and are readable. Do not remove any
labels. Replace any label that is no longer readable.
2.1.1 Hazard Notifications
A hazard notification consists of the following:
•Hazard alert symbol (yellow triangle with black symbol)
•Signal word (DANGER , WARNING , or CAUTION )
•Special notifications related to the hazard (as required)
The signal word labels are attached next to the hazard alert symbol labels on the equipment.
2.1.1.1 Definitions of Signal Words
Signal words describe the level of risk of a particular hazard. The color of the safety label background
indicates the risk, as shown in the following table. The definitions of the signal words are based upon the
ISO3864 definitions.
DANGER (red): This signal word indicates an imminently hazardous situation which,
if not avoided, will result in death or serious injury.
WARNING (orange): This signal word indicates a potentially hazardous situation
which, if not avoided, could result in death or serious injury.
CAUTION (yellow): This signal word indicates a potentially hazardous situation
which, if not avoided, could result in minor or moderate injury.
2.1.1.2 Meaning of Hazard Alert Symbols
The following hazard alert symbols may be installed on your equipment.

3 Equipment Description
3.1 Function
An SMC (Smart Camera) is a camera that sequentially reads pre-printed information from various
packaging surfaces such as labels, bottles, or cartons. The SMC can check both the presence and the
quality of the printed information.
For every product that arrives at the camera, the SMC captures an image. After capturing the image, the
software calculates the characteristics of the product and compares it to reference samples that the user has
taught-in before. In case that one or more of the compared values exceed the set tolerances, the product is
evaluated as 'bad'.
SMCs can process image data on their integrated signal processor. As opposed to PC-based cameras
(such as the HRC) which capture an image and send the result to a connected PC for evaluation, SMCs use
their installed software to evaluate the image by themselves. The user can define an "area of interest" in an
image with so-called control windows and teach the camera how to interpret the information from that
image.
3.2 Equipment Overview SMC Series 3
Components
The hardware of the SMC comprises the following components:
•Housing
•Lens
•Internal illumination
•Mounting block
•Connectors and interfaces
•Status LEDs
•Manual trigger

7 Cleaning
7.1 General Cleaning Procedure
Regular cleaning is very important to keep good system operation. When cleaning your equipment follow
these steps in consultation with your Supervisor (if applicable):
1 Ensure that the production is stopped.
2 Switch off the equipment. If applicable, isolate the equipment from the electrical power supply. Follow
LOTO.
3 Let the equipment cool down.
4 Cover electrical equipment and other surrounding equipment that may get damaged by the cleaning
process.
5 Clean the equipment following the instructions in the Cleaning chapters.
6 After cleaning, ensure that all labels are available and readable. Replace any worn or missing labels.
7 Return the equipment to its normal operation condition. Follow LOTO. Before you restart the equipment,
make sure that all safety devices are back in their original positions and correctly fastened. For example,
if you removed any guards for cleaning, make sure that you reinstall them.
WARNING
Personal injury due to non-compliance to company-specific LOTO
LOTO (Lockout-Tagout) procedures may differ from company to company. Before starting
to work at the equipment inform yourself about the LOTO procedure at the company or
plant.
WARNING
Personal injury and damage to the equipment due to hot parts
During operation, some parts of the equipment may get hot. To avoid personal injury and
damage to the equipment, let the equipment cool down to room temperature before
handling the equipment (e.g. cleaning or maintenance).
CAUTION
Personal damage due to detergents
Wear sufficient protective clothing and hand protection as recommended by the
manufacturer of any detergents used.
NOTICE
Damage due to careless cleaning
The equipment components are made of different materials that have to cleaned using
different detergents. Only use the detergents given in the respective chapter. Do not use
pure alcohol, concentrated acid, or lye.
To prevent water from entering the equipment make sure that all doors and enclosures are
securely closed.
Do not use a high-pressure jet to hose down the equipment.
NOTICE
Damage to products due to unsuitable cleaning and sanitizing procedures
Depending on the products processed in your application (for example, anti-cancer drugs
or food), cleaning and sanitizing may be subject to special regulations. Ensure to be
informed about any relevant regulations and procedures concerning your specific application.

7.2 Cleaning Components Made of Aluminum
In general, components made of aluminum are anodized to protect them against corrosion. During
anodization, an invisible, resistant layer of aluminum oxide is created that protects the equipment.
Depending on the operational use and the conditions in the working environment, the equipment can
become dirty to some extent. The most common causes are fine iron particles in the air, active gases, the
accumulation of sediments, and the build-up of salts.
Overview
Interval1x per day
Required tools and
working materials
1 Observe the steps explained in the chapter [General Cleaning Procedure}Page18].
2 Clean the aluminum components using a slightly wet cloth without applying too much pressure. Change
the cloth several times. This prevents the surface from being scratched by dust particles in the cloth.
3 Wash off any residues with a suitable amount of warm water.
4 Dry the equipment using a cloth without applying too much pressure.
•Warm water
•Several soft, lint-free cloths
7.3 Cleaning the Glass Plate
The plate at the front of the camera is made of glass.
Overview
Interval1x per week
Required tools and
working materials
•Mild glass cleaner or mild solution of soap and water
•Soft, lint-free cloth
1 Observe the steps explained in the chapter [General Cleaning Procedure}Page18].
2 Clean the glass plate at the camera front using a cloth and a suitable detergent.
3 Dry the glass plate using a cloth.
