b) stop category 1 for the main drive in accordance with the requirements of EN 60204-1:2018, 9.2.2.
The stopping sequence for emergency stop shall be:
a) stop of the vertical motion of the frame;
b) alternatively, for horizontal cutting (see 3.1.1.1 - 3.1.1.3), instead of stop of vertical motion of the
frame, stop of translation of the machinery on its carriage or translation of the block trolley on its
rails;
c) stop of drive wheel.
The control circuit for emergency stop shall be at least PL = c in accordance with the requirements of
EN ISO 13849-1:2015.
Verification: By checking the relevant drawings and/or circuit diagrams, calculation, inspection and
functional testing of the machine.
4.2.6 Mode selection
4.2.6.1 General
Where machines are designed to be operated during setting with the movable interlocked guards and/or
protective devices disabled, a mode selector to select between machining mode of operation (see 4.2.6.2)
and machine setting mode of operation (4.2.6.3) shall be provided, and the following conditions shall be
met:
a) the mode selector shall be lockable in each position (e.g. by key or password) and shall be located
outside the peripheral enclosure (see 3.12), e.g. on the main control panel (see 4.2.2 for location of
control devices);
b) the control system for mode selection shall be at least PL = c in accordance with the requirements of
EN ISO 13849-1:2015;
c) the mode selector shall not allow more than one mode to be active at any one time;
d) it shall not be possible to change the mode of operation before the machine has been brought to a
complete and safe stop. The mode selection by itself shall not initiate any machine operation.
Verification: By checking the relevant drawings and/or circuit diagrams, calculation, inspection and
functional testing of the machine.
4.2.6.2 Machining mode of operation
In the machining mode, any movement shall only be possible when the interlocking guards (for definition
see EN ISO 14119:2013, 3.2 and 3.5) and/or protective devices are in place and functional.
Verification: By checking the relevant drawings and/or circuit diagrams and inspection and functional
testing of the machine.
4.2.6.3 Machine-setting mode of operation
In the machine-setting mode of operation if the movable guards are open and/or protective devices
disabled, any movement shall only be possible when the following requirements are met:
a) the tangential speed of wheels shall be limited to 0,2 m/s;
b) any single axis movement shall be controlled by a hold-to-run control. The movement shall be limited
to a peripheral speed of 5 m/min or a maximum increment of 10 mm for a single step. Both the hold-
to-run control and speed/increment monitoring shall be PL = c in accordance with the requirements
of EN ISO 13849-1:2015. If this is technically not possible, alternatively hold-to-run control and the
speed/increment monitoring shall be provided in conjunction enabling device PL = c in accordance
with the requirements of EN ISO 13849-1:2015;
c) the wire-tension system requirements shall be in accordance with the requirements of 4.3.4.2;
d) the translation movement of the block trolley shall be in accordance with the requirements of 4.3.3.3;
e) the hold-to-run control devices and enabling devices for wheel, axes movements, block trolley
translation and wire-tension system, shall be located on the main control panel and/or on the
maintenance panel connected to the machine by a cable or wire-less system (see 4.2.2). For wireless
hand-held control sets, EN 60204-1:2018, 9.2.4, applies.
f) the automatic restart of the machine shall be prevented in accordance with the requirements of
EN ISO 14118:2018, Clause 6.
Verification: By checking the relevant drawings and/or circuit diagrams, calculation, inspection and
functional testing of the machine.
4.2.7 Failure of power supply
Stationary diamond wire saws shall be equipped by mechanical systems that stop any movement of the
machine in case of interruption or reduction of hydraulic or pneumatic pressure levels below a set value
of design.
If a machine stops in any working position as result of a failure of power supply, no further movements
shall be possible.
For electric supply, see EN 60204-1:2018, 7.5, paragraphs 1 and 3.
The requirements of EN ISO 14118:2018, Clause 6, apply.
The safety-related part of the control system to prevent automatic restart shall achieve at least PL = c.
Verification: By checking the relevant drawings, calculation, circuit diagrams, inspection of the machine.
4.3 Protection against mechanical hazards
4.3.1 Transport of the machine
For the transport of the machine, appropriate provisions for the easy and safe handling shall be made in
accordance with EN ISO 12100:2010, 6.3.5.5.
