1. Foreword
This document includes a technical report containing criticalities present onboard the machine and the
consequent technical measures to be taken to remove them.
1.1 Definitions
Damage: Bodily injury or damage to health.
Danger: Potential source of damage. The word “danger” may be qualified in order to define its origin (e.g.
mechanical or electric danger) or the nature of potential damage (e.g. risk of electrocution, risk of cutting, fire
hazard).
Risk: Combination of the probability of occurrence of a damage and the severity thereof.
Residual risk: Risk that remains after taking protection measures.
Protection measure: measure intended to achieve risk reduction, implemented:
• By the design engineer by means of guards and additional protection measures;
• By the user, by means of the provision and use of additional protective equipment.
Criticalities: Danger not removed in the design stage and only detected afterwards, i.e. after the equipment has
been out into service/made available on the market.
Risk assessment: Comprehensive process including both risk analysis and weighting.
Category: Classification of the safety-related parts of a control system with regard to their resistance to failures
and their consequent behaviour under fault conditions, obtained through the structural arrangement of the parts
and/or reliability thereof.
Safety of control systems: Capacity of the safety-related parts of a control system to perform their safety
functions over a given time, according to their specified category.
SRP/CS (Safety-Related Part of the Control System): Safety-related parts of the control system, i.e. part of
a control system which responds to safety-related input signals generating safety-related output signals.
� Page 4 (In accordance with Regulations UNI EN ISO 14121-1 and EN 415-4:2006)
Note 1: the SRP/CS jointly start at the point where the safety-related input signals are generated (including, for
instance, the drive cam and the position switch roller) and end at the output of the power control elements
(including, for instance, the main meter contacts).
Note 2: if monitoring systems are used for diagnosis, these too are considered as SRP/CS.
PL (Performance Level): Reasonable levels used to specify the capacity of the safety-related parts of the
control system to perform a safety function under conditions foreseeable. The performance level (PL) expresses
the probability of hazardous failure for each hour of operation of the SPR/CS system.
Safety function: Function of a machine whose failure may cause immediate risk(s) increase.
SRCF (Safety-Related Control Function): Safety function intended to keep the safety condition of the
machine or to prevent immediate risk increase.
SIL (Safety Integrity Level): Safety integrity for each SRCF function.

1.2 Risk assessment criteria
In the following document is used a so-called “three-phase” iterative method as illustrated in Regulation UNI EN
ISO 12100-1, through which the manufacturer or its authorized representative:
- determines the limits of the machine, which include the intended use and the reasonably foreseeable misuse;
- detects the dangers hat may be generated by the machine and the hazardous situations arising therefrom;
- assesses the risks according to Regulation UNI EN ISO 14121-1, taking into account the severity of the
possible injury or damage to the health and the probability of its occurrence, according to the following ratio:
R = G x F x P x A
G (severity of the damage): 1 (slight and reversible), 2 (serious and reversible), 4 (fatal);
F (frequency of exposure): 1 (rare or infrequent), 2 (frequent or continuous);
P (probability of occurrence of the event): 1 (low), 2 (medium, 4 (high);
A (possibility to avoid the damage): 1 (yes), 2 (no);
- assesses the risks in order to determine whether a risk reduction is required in conformity with
the goal of this directive my means of different types of intervention.
Through the use of bars, the result achieved is highlighted by means of the risk assessment,
considering the risk acceptable (1, 2, 4) as zero risk:
Risk acceptable Risk controllable Risk NON-acceptable
1 …….. 2 …… 4 ………….. 8 …………………………….. 16 ……. 32 ……………….. 64
1.3 Safety level assessment criteria
The choice of the safety category for the design of the different safety-related parts of a control
system is performed using a simplified method based on Regulation UNI EN 14121.
The method consists in assessing the severity of the injury (indicated by S) and the frequency of
occurrence, using auxiliary parameters aimed at improving the assessment, such as:
� Page 6 (In accordance with Regulations UNI EN ISO 14121-1 and EN 415-4:2006)
- The frequency and time of exposure to the danger (F);
- The possibility to avoid the danger (P).
Experience has shown that these parameters can be combined as indicated in the figure below
(Regulation UNI EN 954) so as to provide a bottom-to-top risk scale. It should be noticed that this is
a quality process which only provides a risk assessment.
WARNING - the safety categories outlined in this document concern only the part to be
implemented, so if the safety category of the whole safety circuit is lower, this will also
invalidate that of the newly installed part. The determination of the safety category with
regard to the safety circuit as a whole – and consequently of the compatibility with those
indicated in this technical report – is to be provided by the customer.
In the same figure the preferred category/ies is/are indicated by a large, full circle.
Starting point for the risk assessment for the safety-related parts of the
control system (see 4.3, step 3)
S Severity of the injury S1 Slight injury (usually reversible) S2 Serious injury (usually irreversible), including death F Frequency and/or time of exposure to the risk F1 From seldom to quite often and/or short exposure time F2 From frequent to continuous and/or long exposure time P Possibility to prevent the hazard
P1 Possible under certain circumstances P2 Scarcely possible
Choosing the category Categories B, from 1 to 4 for the safety-related parts of control systems Preferential categories for the reference points (see 4.2) Possible categories which may require additional measures (see B.1)
Measures which may be oversized due to the risk in question
Category
� Page 7 (In accordance with Regulations UNI EN ISO 14121-1 and EN 415-4:2006)
A smaller, full circle is used to countermark the categories requiring the implementation of further
accident prevention measures, while a large, empty circle is used to indicate the categories providing
the highest guarantees (justified in case of high or not perfectly defined hazards).
1.4 Criteria for determining the performance level required (PLr)
The level of resistance to failures “PLr” that the SRP/CS system must guarantee can be deduced
either from the standard of type “C” concerning the machine under examination or – if the machine
has not yet been provided with a specific product standard – it is obtained using a simplified method
based on Regulation UNI EN 14121 and applying the tree diagram present in the figure below (…from
Regulation UNI EN ISO 13849-1):
S Severit y of the injury
S1 Slight (injury usually reversible)
S2 Serious (injury usually irreversible or fatal)
F Frequenc y and/or durat ion of the exposure to the risk
F1 From rare to not very often and/or short time of exposure
F2 From frequent to continuous and/or long time of exposure
P Possibilit y to prevent the risk or limit the damage
P1 Possibility under specific conditions
P2 Scarcely possible
The factors taken into consideration are:
� Page 8 (In accordance with Regulations UNI EN ISO 14121-1 and EN 415-4:2006)
- Severity of the injury (indicated by S) the person might suffer in the event of an accident
- Frequency and/or time of operator’s exposure to danger (F)
- Possibility to avoid the danger (P).
The purpose of Regulation UNI EN ISO 13849-1 is in any case to define a Performance Level (PL) of
the SRP/CS system in terms of hazardous failures, which during the planning stage shall be compared
with the performance level required (PLr) based on the extent of the risk (PL≥PLr), according to the
following table:
Performance
Level
(PL)
Fields of the probability of hazardous failures per hour
(PFHD)
(1/h)
From: Up to:
a ≥10-5 <10-4
b ≥3· 10-6 <10-5
c ≥10-6 <3· 10-6
d ≥10-7 <10-6
e ≥10-8 <10-7
Table: Performance Levels (PL) provided for by Regulation UNI EN ISO 13849-1
WARNING – Since Regulation EN 13849 is a standard of type B1, if the machine is covered
by a standard of type “C”, this latter is the one to be held valid; therefore, should this
latter still refer to the “old” category classification, this is the one to be considered.
1.5 Criteria for determining the safety integration level (SIL)
� Page 9 (In accordance with Regulations UNI EN ISO 14121-1 and EN 415-4:2006)
The safety integrity level (SIL) to be assigned to the safety control functions (SRCF) which shall
ensure the reduction of the risks on the machine resulting from any hazardous situations can be
deduced either from the standard of type “C” concerning the machine under examination or – if the
machine has not yet been provided with a specific product standard – it is obtained from the following
matrix: ±
To complete a process which in the first analysis leads to carry out the risk assessment for each source of
danger or hazardous event adopting a method based on Regulation UNI EN 14121 which uses the
following relation (…from Regulation CEI EN 62061):
R = Se x (Fr + Pr + Av) = Se x Cl
Se (severity of the damage):
Fr (frequency and duration of the exposure):
Irreversible: death, loss of an eye or arm Irreversible: fracture of one or more limbs, loss of one or more fingers Reversible: requires the intervention of a doctor
Consequences Consequences Consequences Consequences

WARNING – Since Regulation EN 62061 is a standard of type B1, if the machine is covered
by a standard of type “C”, this latter is the one to be held valid; therefore, should this
latter still refer to the “old” category classification, this is the one to be considered

2. Analysis of current criticalities
Following the inspection carried out in your plant in order to execute a criticality analysis of the
machine present on site, for the palletizer classified by Regulation EN 415-4 as a “palletizer with load
stacking from above with top layer grouping”, it was possible to highlight the results described below.
2.1 Palletizer
For the “one-position” pelletizing machine, which is partly covered by the standard of type “C” UNI EN
415-4:2006 – Safety of packaging machines. Palletizers and depalletizers, operating both in the
automatic mode with automatic loading and unloading and in the semi-automatic mode with manual
unloading, and intended for handling and palletizing paperback and hardcover books, glued and sewn
book blocks, magazines, catalogues and phone books, shrink-wrapped or tied up piles of any product
and boxes.

2.1.1 Passage of output PALLETS
1. The operator’s access through the pallet output point is protected by means of multiple-beam
photoelectric barriers with inhibition function. These barriers – placed at a distance of 270 mm from the
danger zone – are intended to protect an access passage 1,140 mm wide, on top of which is installed a
muting lamp.

Protection m easur es: Technical
The solution adopted to prevent free access of the operator during the operation of the machine has to
be reviewed first of all because the relevant standard provides that during the inhibition of the barriers –
in order to prevent the operator from entering the shelters – the maximum distance “A” between the
machine and the loaded pallet is 200 mm, against 245 mm distance – which in some cases may even
be greater – you may have currently;
Figure 1
Furthermore, the safety distance “B” between the optical barrier and the danger zone which is presently
approx. 270 mm should be raised at least to 1,200 mm if you want to go on using hybrid barriers
(currently in use on the machine), since according to Regulation EN 999 these are considered multiple-
beam barriers. If, on the contrary, barriers with 35 mm resolution are used, this distance “B” may be
reduced to approx. 600 mm (for a more precise distance, you will need to assess the response time of
the barrier used and the stopping time of the machine). In both cases, however, the muting function
and a barrier height of 1,600 mm shall be confirmed.

Distance “A” = distance between the loaded pallet and the machine guard or barrier.
Distance “B” = distance between the machine danger zone and the barrier.

maximum size allowed by Regulation UNI EN 619:2004. However, it is necessary to check that the distance from the danger
zone is placed at a distance of at least 1,000 mm as required by Regulation UNI EN 13857.

2.1.3 Access to the pallet warehouse 1. The lateral zone of the machine which allows the operator to lean into the pallet warehouse is enclosed within mobile
guards interlocked with safety microswitches. The locking of the guards (signalled by the red warning light) is only activated
during some phases of the cycle, e.g. during the handling of the pallets (software management).

Protection measures: technical
a) The mobile guard has a slit-shaped opening “M” of size greater than 10 mm used by the operator to open
and whose dimensions allow accessing the danger zone with one’s hand. Since it is impossible to place the
shelter at a distance included between 120 and 850 mm, are required by Regulation UNI EN 13857, from
the danger zone, this opening must be limited to 6 mm, i.e. you must close the opening using a retractable
handle of commercial type.
b) The analysis of the risk and of the safety category leads to obtain, for this safety function, a PLr = b. It is therefore
necessary to use a circuit-based solution like the one currently adopted and further below proposed with indication in the
technical file of the frequency of checks on the proper functioning of the safety function:
You should therefore use a safety device such as the existing safety microswitch as well as a safety module (currently missing
but replaced with a functional PLC), besides the monitoring represented – in the case in point – by the automation PLC.
Currently, therefore, the existing control circuit can be schematized as follows:
dove:
Single Channel with Monitoring
Cat. 2
� Page 22 (In accordance with Regulations UNI EN ISO 14121-1 and EN 415-4:2006)
I = Input, i.e. safety microswitch with high MTTFd and DC
PLC = Logics and monitoring, i.e. automation PLC with low and zero MTTFd and DC, respectively
KM = output, i.e. functional switch or solenoid valve which inhibits the operation of the engines or pneumatic actuators “M” with
low MTTFd
From Annexe K to Regulation EN 13849-1 it can be deduced that it is possible to perform the safety function “opening of
guards to access to the inside of the machine” with PL ≥ b if the overall MTTFd of the function is ≥ 7.5 years .
To achieve the same result, you can use a safety circuit of category 3, like the one described below:
Which ses, for instance, components with double contact and monitoring performed by a safety module, with no indication in
the technical file on frequency of checks for the proper functioning of the safety function.
From Annexe K of Regulation EN 13849-1 it can be deduced that it is possible to perform the function safety “opening of
guards to access to the inside of the machine” with PL ≥ b if the overall MTTFd of the function is ≥ 3.9 years .

• Safety category 2 for the interlocking devices,
i.e. MTTFd of the safety function greater than
or equal to 7.5 years.
• Safety category 4 for the interlocking devices,
i.e. MTTFd of the safety function greater than
or equal to 3.9 years.
Products / solutions :
• Leaving the safety circuit unchanged, in category 2, you must
check the MTTFd of the safety function; if this later does not
meet the value found, it is necessary to modify the operational
logic by inserting a safety PLC or a safety module with high
DC (diagnostic covering).
• Installation of encoded safety magnetic switches not in
contact to detect movements of the axes when the guard is
opened in case you want to use a safety circuit belonging to
category 3 [mod. F3S-TGRNSMC-20-05]

2.1.4 Access to the shelters from the front side 1. The front side is provided with three doors with as many safety microswitches which, on opening the guard, send a signal
to the PLC. If the doors are opened during the handling (lifting and translation of the axes) of the pile, there will be a drop in
the power – with a delay of 0.5 seconds – thanks to the intervention of a magnetic switch; the doors can also be opened
with the axes in the resting position, with no power interruption. The position is in any case signalled by a micro magnetic
switch.

2.2 Safety signs
It is necessary to install appropriate signs as well to provide information essential to ensure the
workers’ safety to be placed near the control station (operator’s panel) and intervention area (pallet
input and output zone), such as:
Here is an example of plates to be placed near the keyboard:
On the electrical cabinet or near electrical equipment, where there must be the following signs:

2.3 Further remarks
1. During the assessment of the criticalities the operating and maintenance manual produced by you
was reviewed, finding out that information is a little insufficient, as specified under paragraph
1.7.4 of Annexe I to Directive 98/37/CE on machinery matters and Regulation EN 415-4, and
further specified below:
…each machine must be accompanied by instructions for use providing at least the following
information:
- Intended conditions of use (intended and non-intended use)
- Mode of transport of the machine
- Mode of installation
- Indications on the noise produces by the machine
- Indications on marking
- Indication of possible residual risks
- Indication of the workstation(s) which can be occupied by the operators
2. During the inspection, 3 different labels for the EC conformity marking were identified, of which
� Page 33 (In accordance with Regulations UNI EN ISO 14121-1 and EN 415-4:2006)
one on the machine itself and another two on the rollers. This implies for the purposes of the Machinery Directive,
respectively, a CE conformity marking, with technical file and manual, for the machine we define as a Palletizer or
Palletizing machine and two statements of incorporation for the rollers, along with technical documents, i.e. assembly
instructions and list of the RES applied.
In order to avoid all this, it is advisable to certify the machine and the rollers together, as though they formed one machine,
therefore providing a single EC label.
