An Intended Use applies if …
the labeler is used exclusively for automatic labeling of moved respectively stopped
products.
maintenance is only carried out after stopping the labeler.
the labeler is used with specified products as well as specified labels. Products and
labels have to meet all * documented specifications agreed upon between manufac-
turer and customer.
* "documented specifications" are normally laid down in the LSS (Labeling Systems Survey) and handed out to the
customer with the confirmation of order.
the labeler is operating in explosion-proof environments (not intended for explosion-
risk areas) !
the labeler does not come in direct contact with food products.
the labeler is not operating outdoors.
the labeler is used with an additional pneumatic shutter at the aperture for the Tamp
when operating in a wet environment.

failures at the labeler affecting the safety have to be reported and immediately re-
solved by trained and briefed personnel.
maintenance is kept and performed correctly.
the labeler is used exclusively under faultless conditions.
safety equipment is not by-passed or abrogated.
arbitrary changes at the machine are omitted.
the labeler is used or operated by adequate personnel, refer to “Authorized Person-
nel” (s. page 20). These persons must have read and have to be familiar with the
content of the manual.
Handling the labeling system without considering one of these points is not for the in-
tended purpose and can cause serious damages to persons or properties.
Chapter 2 Safety Regulations Alpha Compact 32708612
Version: 14.12.2012 page 16 of 135
Reasonably Forseeable Misuse
Another use as fixed in the „Intended Use“ or even more applies as not intended!
For damages caused by not inteded use:
the operator bears the complete responsibility,
the manufacturer assumes no liability.
If you do not use the system according to the regulations, risks may occur!
Not inteded uses are e.g.:
operation in exlosible atmosphere
the labeler comes in contact with food …
Retrofitting and Changes at the Labeling System
Unauthorized retrofitting and changes at the system lead to an immediate expiration of li-
ability and warranty covered so far by the manufacturer! This is also valid for interventions
and program changes at programmable control systems as well as program changes at
control units as far as they are not described in this Manual.
The electromagnetic performance of the system can be affected by amendments or
changes of any kind.
Do not arrange any changes or amendments at the systems without consultation and writ-
ten approval of the manufacturer.

Sources of Danger at Labeler
Fig.: 2-1: Sources of Danger at Labeler
The rollers of the unit that brings the objects forward rotate in the opposite direction so
that objects may be detected and may be pulled between the rollers. A protective plate
here protects the user from injuries. The rewinder is motor-powered. Objects may be de-
tected. There is the danger of being crushed between rewinder table and cabinet. The
power is limited to less than 50 N by a round belt and protects the user from injuries.
There exists the danger of crushing at the bracket of the peeler blade when the peeler bar
swings out. A protective plate protects the user from injuries. In the area of the peeler
blade, there may also arise a danger of being crushed by the customer’s product feed.
Depending on the conveying system and the fed products there may be protective
measures by customer necessary.
Chapter 2 Safety Regulations Alpha Compact 32708612
Version: 14.12.2012 page 18 of 135
*²Labeler with optional applicator
Fig.: 2-2: Sources of danger at the applicator Tamp Blow, rotating tamp and pneumatic peeler blade
All applicators of labelers have been designed according to safety criteria. The arising
forces at the Tamp are limited to 50 Newton for both movements of the stroke, which may
be potential risks of injury to persons classified as low (usually reversible). Therefore addi-
tional protective devices (e.g. safety guards, protective cabinet…) are not required. The
limitation of the Tamp force to 50 Newton is realized by using a smaller cylinder diameter.
The prescribed pressure of the compressed air may not be exceeded (see p.25).
*² Only if labeler has the appropriate feature.

Safety Instructions
Danger caused by direct or indirect contact with live parts.
DANGER TO LIFE!
Contact of persons with live parts.
Before performing any work on electrical equipment of the la-
beler, separate from power source.
Work on electrical equipment of the labeler may only be carried
out by electricians.
The electrical equipment of the labeler has to be checked regu-
larly. Damages have to be repaired professionally and imme-
diately.
Incorrect and faulty connected control units can cause fail-
ures/damages and lack of safety.
To avoid static electricity, ground the labeling system.
Danger caused by highly combustible label material.
FIRE DANGER!
Label web is highly combustible. Risk of injury by fire and smoke.
Keep clear from naked flame and source of ignition.
Danger caused by actively triggered movements.
DANGER OF DRAWING IN!
Rotating elements at the labeler, rewinder, web brake and rollers
of the friction unit.
Do not grip in, at or between the moving parts.
Danger from moved products.
DANGER OF BEING CRUSHED!
At *²pivoted peeler blades the passing products push away
the peeler blade. Thus the distance between deflection roller
and bracket of peeler blade is decreased. Objects may then
be crushed.
At *²fixed mounted peeler blade, objects may be crushed
between product and peeler bar.
When using an *²applicator, objects may be crushed during
extension and retraction movement or swinging movement
between tamp or peeler bar.
Maintain a distance from *²peeler blade, bracket of peeler
blade, *²tamp pad and the products.

Health hazard caused by rough surfaces
HEALTH HAZARD!
The friction rollers have a rough surface. Long contact may cause
abrasions.
Do not grip in, at or between moving parts.
Health Hazard due to inappropriate handling of lubricants and
detergents
HEALTH HAZARD!
For used lubricants and detergents, the valid information of the
safety data sheets of the manufacturers and the valid safety- and
disposal regulations have to be observed and followed for each
product.
Risk of injury at angles and edges
RISK OF INJURIES!
Sharp angles and edges may cause grazing and gashes at the
skin. Keep the working place always clean. The label web builds
sharp angles.
If work is performed close to sharp angles and edges, proceed
cautious. Remove parts that are not required.
In case of doubt wear safety gloves.
Attention when inserting and changing label web.
Engine (motor) and controller have to be grounded (ground-
ing screw next to motor plug). Short time overloads influence
the internal direct-current voltage in a negative way (chassis
on 0V potential) and should be avoided.
Remaining Risks
The labeler is constructed for a safe operation. Hazards that are not preventable due to
construction purposes are limited as far as possible by protection devices. A certain
amount of risk is always existent! The knowledge about the remaining risks assists you to
arrange your work safer and to avoid incidents. In order to avoid the dangers, please ob-
serve additionally the particular security advice in the single chapters.
