In addition, the machine should be designed according to 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). 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. 5.2 Controls 5.2.1 Safety and reliability of control systems 5.2.1.1 General For the purposes of this document a safety related part of control system means the system from the initial device, e.g. push button or position detector or sensor up to and including the power control element of the final machine actuator or element, e.g. motor or brake. The safety related parts of control system of this machine are those for 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 of the saw-blade(s) rotation, the movements of the saw unit(s), the work-piece feed mechanism: PL=c (see 5.2.3, 5.2.6);  normal stopping: PL=c (see 5.2.4);  emergency stop: PL=c (see 5.2.5);  interlocking: PL=c (see 5.3.7);  interlocking between the feed chain motor with the position of the saw spindles: PL=c (see 5.2.6);  interlocking with guard locking: PL=c (see 5.3.7);  prevention unexpected start-up after failure of the power supply: PL=c (see 5.2.8);  hold-to run control: PL=c (see 5.3.7.3);  control duplication (where fitted): PL=c (see 5.2.7);  initiation of the braking system: PL=b or PL=c (see 5.3.4). For all components exposed to environmental conditions, e.g. dust, fumes and/or gases, these conditions shall be taken into account. Verification: By checking the relevant drawings and/or circuit diagrams and inspection of the machine. NOTE For the component characteristics a confirmation from the manufacturer of the component can be useful. SIST EN 1870-15:2012

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 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 controls are located on a separate movable control console it shall be of the type with cable connection to the machine and its position relative to the machine shall be indicated in the instruction handbook (see 6.4). For positions of emergency stop, see 5.2.5 and for the position of the hold-to-run control devices, see 5.3.7.3. Verification: By checking the relevant drawings and/or circuit diagrams, inspection and relevant functional testing on the machine. 5.2.3 Starting The requirements of EN ISO 12100:2010, 6.2.11 and EN 60204-1:2006, 9.2.5.2 apply and in addition: Before starting or restarting the machine all the safeguards shall be in place and functional. This is achieved by the interlocking arrangements described in 5.3.7. Start or restart shall only be possible by actuation of the start control device provided for that purpose. Starting of the saw spindle drive motor(s), the powered movements of the saw units and the powered movements of the saw spindles (if provided) shall only be possible by manually operated control devices. For starting the feed chain motor, see 5.2.6. For starting the feed chain drive motor, either a manually operated control device or a foot pedal shall be provided. Where for initiating the movement of the feed chain a foot pedal is used this control device shall in accordance with the following requirements: a) it shall be of the hold-to-run control type; b) it shall be shrouded against unintentional activation; c) the force required to actuate the foot pedal shall not exceed 350 N; d) the safety related parts of the control system shall conform to at least PL=c in accordance with the requirements of EN ISO 13849-1:2008.
