For the purpose of this European Standard “well tried” components and principles means: a) electrical components if they comply with relevant standards including the following: !EN 60947-5-1:2004" (section 3) for control switches with positive opening operation used as mechanically actuated position detectors for interlocking guards and for relays used in auxiliary circuits; !EN 60947-4-1:2001" for electromechanical contactors and motor-starters used in main circuits; !HD 22.1 S4:2002" for rubber-insulated cable; !HD 21.1 S4:2002" for polyvinyl chloride cable if this cable is additionally protected against mechanical damage by positioning (e.g. inside frames). b) electrical principles if they comply with the first four measures listed in 9.4.2.1 of !EN 60204-1:2006". The circuits shall be “hardwired” or if electronic components are used in safety related control circuits they shall be in accordance with 9.4.2.2 (i.e. redundancy with cross-monitoring) or 9.4.2.3 (i.e. diversity) of !EN 60204-1:2006"; c) mechanical components if, for example they operate in the positive mode in accordance with the description given in !4.5 of EN ISO 12100-2:2003"; d) mechanically actuated position detectors for guards if they are actuated in the positive mode and their arrangement/fastening and cam design/mounting comply with the requirements of 5.2.2 and 5.2.3 of EN 1088:1995; e) interlocking devices with guard locking if they have as minimum unconditional unlocking in accordance with the requirements of Annex N of EN 1088:1995; f) pneumatic and hydraulic components and systems if they comply with EN 983:1996 and EN 982:1996 respectively; g) two-hand control devices if they are as a minimum type 3B in accordance with the requirements of EN 574:1996; h) pressure sensitive mats if they are in accordance with at least type 2 of EN 1760-1:1997 and if they are tested together with their associated control circuits at least at each starting of the machine; i) active opto-electronic protective devices (light beam(s)) if they comply with the requirements of at least type 2 of !CLC/TS 61496-2:2006" and if they are tested together with the associated control circuits at least at each starting of the machine; j) pressure sensitive edges (bumpers) and pressure sensitive bars (trip bars) if they are in accordance with the requirements of at least type 2 of !EN 1760-2:2001" and if they are tested together with their associated control circuits at least at each starting of the machine.

EN 1870-9:2000+A1:2009 (E) 13 Time delay devices used in hardwired safety related control circuits may be of category B according to
!EN ISO 13849-1:2008" if the time delay device is designed for at least one million actuations. Verification: By checking the relevant drawings and/or circuit diagrams !and" inspection of the machine !deleted text". !NOTE For components characteristics the information from the component supplier can be useful. " 5.1.2 Position of controls
See 10.1.1 of !EN 60204-1:2006" and in addition: 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 central between the saw units ± 300 mm for each adjusted position and not less than 300 mm from the closest position of a sawblade. 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 5.1.5) shall be positioned: e) within 1,0 m of the loading position; f) within 1,0 m of the unloading position; g) at the main control panel; h) within 500 mm of the two hand control (where provided); i) within 3,0 m of the saw unit. Verification: By checking the relevant drawings and/or circuit diagrams, inspection and relevant functional testing on the machine. 5.1.3 Starting See !4.11 of EN ISO 12100-2:2003" and 9.2.5.2 of !EN 60204-1:2006" and in addition: For the purpose
