and the related control system shall be at least PL=c in accordance with the requirements of EN ISO 13849-1:2008; b) if a time delay is used it shall be of fail safe technique e.g. of capacity type conforming to the requirements of 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, measurement and relevant functional testing of the machine. NOTE For the components characteristics, a confirmation from the components' manufacturers can be useful. 5.2.2 Position of controls
Hand-operated control devices for start and stop of the motor for the saw spindles, emergency stop, integrated feed, reset controls and hold-to run shall be located in an area between 600 mm and 1700 mm above the floor level. NOTE For electric control devices, see also EN 60204-1:2006, 10.1.1. Where the machine is fitted with a two-hand control device, it shall be: a) situated at the front of the machine; b) below the workpiece support; c) at a minimum height above floor level of 750 mm; d) such that where the maximum distance between the saw units is ≥ 2,5 m it is capable of being located centrally between the saw units ± 300 mm for each adjusted position and not less than 300 mm from the closest position of a saw blade. Where the control for the clamps is separate from the two hand control it shall be within 400 mm measured horizontally to the two hand control. According to the size of machine, one or more emergency stops (see 5.2.5) shall be positioned: 1) within 1,0 m of the loading position; 2) within 1,0 m of the unloading position; 3) at the main control panel; 4) within 500 mm of the two hand control (where provided); 5) within 3,0 m of the saw unit. Verification: By checking the relevant drawings, inspection, measurement and relevant functional testing on the machine. SIST EN 1870-9:2012

NOTE For the purpose of this document "all the relevant safeguards in place and functional" is achieved by the interlocking arrangements described in 5.3.7 and 5.3.8 and "operation" means rotation and/or powered adjustment of any saw spindle and/or powered movement of any workpiece holding and feeding device and/or any machine element in which a saw blade is mounted.
b) Start or restart shall only be possible by actuation of the start control device provided for that purpose. c) The closure of movable interlocked guards shall not lead to an automatic restart of hazardous movements. d) The exceptions described in EN 60204-1:2006, 9.2.5.2 are not relevant. e) For semi-automatic machines, the cutting stroke shall only be capable of being started with a manually operated control device after saw blade rotation and clamping have been initiated. f) For all machines, the cutting stroke shall only be capable of being started after saw blade rotation and clamping have been initiated and when: 1) all interlocked guards are in the closed position; 2) no person is standing on pressure sensitive mats (where provided); 3) no person is within the beams of an active opto-electronic protective device (where provided). g) All start and/or reset controls shall be located outside protected areas and not reachable when standing inside a protected area. h) The safety related part of the control systems (also see 5.2.1) for starting and the interlocking arrangements shall be at least PL=c in accordance with the requirements of EN ISO 13849-1:2008.

When initiated, the stopping sequence shall be: a) initiate the return stroke of the saw unit(s); b) cut power to saw spindle drive motors and initiate the brakes (if provided); c) when braking sequence is complete, cut power to the brakes (if electrical brake is provided); d) remove power to the workpiece clamping device. SIST EN 1870-9:2012

b) Where the machine is fitted with pneumatic and/or hydraulic actuators, the restoration of the energy supply shall not result in a restart of any machine actuator.
c) The control system to prevent automatic restart shall be designed to achieve 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 and relevant functional testing on the machine. SIST EN 1870-9:2012
