Start or restart shall only be possible by actuation of the start control device provided for that purpose. Closure of movable interlocked guards shall not lead to an automatic restart of hazardous movements. The safety related part of the control systems (also see 5.2.1) for starting and the interlocking arrangements as indicated in 5.2.7, 5.2.8, 5.3.6, 5.3.7 shall be at least PL = c in accordance with the requirements of
EN ISO 13849-1:2008. When fitted with a unit for scoring and/or post-formed edge pre-cutting, the scoring saw blade spindle drive motor or the post-formed edge pre-cutting saw blade drive motor shall not be capable of being started before the main saw blade drive motor. For electrically operated machines, the requirements of 9.2.5.2 of EN 60204-1:2006 apply but the exceptions described in 9.2.5.2 of EN 60204-1:2006 are not relevant. The safety related part of the control systems (also see 5.2.1) for interlocking between starting of the main saw blade drive motor and starting of the scoring saw blade spindle drive motor or the post-formed edge pre-cutting saw blade drive motor shall be at least PL = c in accordance with the requirements of
EN ISO 13849-1:2008 (see also 5.2.6, 5.3.7). Verification: By checking the relevant drawings and/or circuit diagrams, inspection of the machine and relevant functional testing of the machine. 5.2.4 Normal stopping The machine shall be fitted with a stop control whereby all saw blades and – if fitted – a demountable power feed unit can be stopped (see also 5.2.8). The stopping shall include disconnection from energy supply of the corresponding actuators except workpiece clamping unless STO in accordance with EN 61800-5-2:2007 is used. For normal stopping of PDS(SR) (power drive system, safety related) see 4.2.2.2 "safe torque off (STO)” and 4.2.2.3 “safe stop 1 (SS1)” of EN 61800-5-2:2007. If the machine is fitted with a spring operated mechanical brake, this stop control shall be of category 0 in accordance with the requirements of 9.2.2 of EN 60204-1:2006. If the machine is fitted with any other type of brake e.g. electrical brake, this stop control shall be of category 1 in accordance with the requirements of 9.2.2 of EN 60204-1:2006. Wher
