4.1 General
Machinery shall comply with the safety requirements and/or protective/risk reduction measures of this
clause. In addition, the machine shall be designed according to the principles of EN ISO 12100:2010 for
relevant but not significant hazards that are not dealt with by this document.
The safety related parts of the control system shall be in accordance with EN ISO 13849-1:2015 or
EN 62061:2005, EN 62061:2005/A1:2013, EN 62061:2005/A2:2015. The required performance levels
(PL ) or Safety Integrity Levels (SIL) are given in the relevant subclauses.
r
4.2 Mechanical hazards
4.2.1 Access through openings in the agglomerator chamber
In the agglomerator there are openings designed and constructed for feeding the material, discharging
the material, inspecting the process inside the agglomerator chamber and changing or maintaining the
agglomerating tools.
Access to agglomerating tools and their rotating support elements in the agglomerator chamber through
openings shall be prevented by one or more of the following:
— fixed guards in accordance with EN ISO 14120:2015, that may be distance guards as defined in
EN ISO 14120:2015, 3.2.2;
— interlocking guards with guard locking in accordance with EN ISO 14120:2015 and
EN ISO 14119:2013, such that the guards remain closed and locked until all motions of the
agglomerating tools have ceased; safety related parts of the control system shall be according to:
— PL = d or SIL = 2 for the interlocking function and
r
— PL = c or SIL = 1 for the locking function.
r
Safety distances preventing access to agglomerating tools and their rotating support element, if any, shall
be in accordance with !EN ISO 13857:2019", Table 2, Table 3, Table 4 and/or Table 6.
If the feeding equipment, or its part or the discharge system act as a guard and is capable of being moved
out of position without the use of a tool and the resulting access to the agglomerator does not comply
with the above safety distances of !EN ISO 13857:2019", then it shall act as an interlocking guard
with guard locking in accordance with EN ISO 14119:2013, such that it remains locked in position until
all motions of the agglomerating tool have ceased; safety related parts of the control system shall be
according to:
— PL = d or SIL = 2 for the interlocking function and
r
— PL = c or SIL = 1 for the locking function.
r
If the dimensions of the opening are greater than 500 mm × 400 mm, so that whole body access is
possible, falling through the feed opening shall be prevented by positioning the lower edge of the opening
at a minimum height of 1,20 m from the working level.
If, for operational reasons, it is necessary to move agglomerating tools and their support when
interlocking guards are open, e.g. to change or to adjust the agglomerating tools, the rotating support
shall be designed to allow its manual movement and preventing any contact with the agglomerating tools
(e.g. fitting removable handles). See 6.2.3.
If the manual rotation is not possible (e.g. for large machines due to the mass of the rotating support) a
specific operational mode shall be allowed which permits the powered rotation of the agglomerating
tools and their support when the interlocking guards are open. This specific operational mode shall:
— be activated by a selector switch in accordance with EN ISO 12100:2010, 6.2.11.10, that can be locked
in all positions by a removable or coded key or other means that prevent unauthorised selection and
— enable the rotation of the agglomerating tools and their support by a hold-to-run control device in
combination with a maximum peripherical rotating speed of 2 m/min, in accordance with
EN ISO 12100:2010, 6.2.11.9 and with !EN 60204-1:2018, 9.2.3.5, 9.2.3.6 and 9.2.3.7".
The safety related parts of the control circuit shall be PL = d or SIL 2.
r
To avoid any unexpected motion of rotating support of agglomerating tools during their changing or
adjusting, appropriate devices, e.g. mechanical lock with pins, shall be provided.
See 6.2.2, 6.2.3 and 6.2.5.
The temperature of the material that is processed shall be automatically controlled, e.g. using a cooling
system or reducing the speed of the rotating agglomerating tools, etc., in order to prevent the blocking of
the rotating agglomerating tools.
The safety related parts of the control system shall be according to PL = b.
r
See 6.2.10.
4.2.2 Feed material that is not pre-cut
If the intended use of the agglomerator is to process continuous films, fibres, strands or similar materials
likely to cause entanglement, then sensitive mechanically actuated protective equipment (e.g. pressure
sensitive edge, wire, etc.), in accordance with EN ISO 13856-2:2013 or EN ISO 13856-3:2013 shall be
provided at the feed opening to automatically stop the material being fed in when actuated. The sensitive
protective equipment shall be positioned at a height between 1,20 and 1,40 m in a way that it is
automatically actuated in case of entanglement by a force less than or equal to 250 N.
The safety related parts of the control system shall be according to PL = d or SIL = 2.
r
See also 6.2.4.
4.2.3 Moving parts of discharge systems
Access to powered moving parts of discharge systems shall be prevented by one or more of the following:
— fixed guards in accordance with EN ISO 14120:2015;
— interlocking guard in accordance with EN ISO 14120:2015 and EN ISO 14119:2013 and positioned
in accordance with EN ISO 13855:2010.
Safety distances shall be in accordance with !EN ISO 13857:2019", Table 2, Table 3, Table 4 and
...
