NOTE For guidance in connection with risk reduction by design, see EN ISO 12100:2010, 6.2, and for safeguarding measures, see EN ISO 12100:2010, 6.3. In addition, the machine should be designed in accordance with the principles of EN ISO 12100:2010 for hazards relevant but not significant, which are not dealt with by this document (e.g. sharp edges of the machine frame). 5.2 Controls 5.2.1 Safety and reliability of control systems 5.2.1.1 General For the purpose of this document, safety related part of a control system means the system from the initial actuator or position detector or sensor up to and including the power control element of the final machine final actuator e.g. motor or brake. Safety related parts of the control system of this machine comprise parts concerning the following functions and they shall fulfil at least the requirements of the PL given below in accordance with the requirements of EN ISO 13849-1:2008:  starting and restarting: PL=c (see 5.2.3);  normal stopping: PL=c (see 5.2.4);  prevention of unexpected start-up after failure of the power supply: PL=c (see 5.2.5);  the braking system: PL=b or PL=c (see 5.2.4, 5.3.4);  monitoring of the clamp-closing pressure (if workpiece clamping is fitted): PL=c (see 5.3.7). Verification: By checking the relevant drawings and/or circuit diagrams and inspection of the machine. 5.2.1.2 Use of protective devices Protective devices shall be in accordance with the specific standards. For the devices listed below the following requirements apply: SIST EN 1870-17:2012

If fitted with pneumatic work-piece clamping the controls for clamping and unclamping shall be either: 1) where a manually operated controls device is used, situated at the front of the machine below the work-piece support;
2) where a foot pedal is used, situated on the floor within 1,0 m of the cutting line when it is at 90° to the fence; Where an automatically operated switch is used, it shall be ensured that the work-piece is securely clamped before chipping commences. Verification: By checking the relevant drawings, measurement and inspection of the machine. 5.2.3 Starting Before starting or restarting the machine all the safeguards shall be in place and functional. This is achieved by the interlocking arrangement described in 5.3.6. NOTE Starting means switching on the saw spindle drive motor. Start or restart shall only be possible by actuation of the start control device provided for that purpose. For electrically operated machines the requirements of EN 60204-1:2006, 9.2.5.2 apply. The direction of the rotation of the saw spindle shall be such, that the cutting force of the saw blade is directed against the fence. The safety related part of the control system for starting the rotation of the spindle (see 5.2.1) shall conform to at least PL=c in accordance with the requirements of EN ISO 13849-1:2008. Verification: By checking the relevant drawings and/or circuit diagrams, inspection of the machine and relevant functional testing of the machine. SIST EN 1870-17:2012

c) polycarbonate with a wall thickness of at least 3 mm or other plastic material passing the test in Annex C; d) cast iron with an ultimate tensile strength of at least 200 N mm-2 and a wall thickness of at least 5 mm. Verification: By checking the relevant drawings, tensile strength, measurement, for materials with characteristics other than those given for polycarbonate in c) above by performing the test in Annex C and inspection of the machine. NOTE For the ultimate tensile strength a confirmation from the manufacturer of the material can be useful. 5.3.3 Tool holder and tool design 5.3.3.1 Saw blade design If the machine is fitted with saw blades, they shall be in accordance with the requirements of
EN 847-1:2005+A1:2007. See also 6.3 j). Verification: By checking the relevant drawings and inspection of the machine. 5.3.3.2 Saw spindle design The saw spindle shall be manufactured from steel with an ultimate tensile strength of at least 580 N mm-2 and fulfil at least the tolerances given in Annex B.
