The sawblades can be mounted on one or more saw spindle(s) which may be capable of vertical adjustment. The sawblades may be capable of axial adjustment. The sawblade spindle(s) may be arranged so that they are: a) all mounted above the workpiece support; b) all mounted below the workpiece support; c) mounted both above and below the workpiece support. The cutting mode can be ‘against the feed’ (see Figure 1a) or ‘climb cutting’ (see Figure 1b) or a combination of both.

These control systems shall, as a minimum, be designed and constructed using “well tried components and principles”. For the purposes of this European Standard “well tried components and principles” means: a) electrical components if they comply with relevant standards including the following: 1) !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; 2) !EN 60947-4-1:2001" for electromechanical contactors and motor-starters used in main circuits; 3) !HD 22.1 S4:2002" for rubber-insulated cable; 4) !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) mechanical components if they comply with !4.5 of EN ISO 12100-2:2003"; c) 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 and 5.3 of EN 1088:1995; d) hydraulic and pneumatic components and systems if they comply with EN 982:1996 and EN 983:1996 respectively; SIST EN 1870-4:2002+A1:2009
EN 1870-4:2001+A1:2009 (E) 14 e) 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 either “hardwired”, or if electronic components are used in safety related control systems 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"; f) interlocking devices with guard locking if they satisfy the requirements of 5.2.7. Time delay devices used in hardwired safety related control circuits may be of category B in accordance with !EN ISO 13849-1:2008" if the time delay device is designed for at least one million actuations. Verification: By checking 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 Electrical controls for start and stop of the motor(s) for the saw spindle(s), for the feed and for the height adjustment of the upper roller support shall be situated either as shown in Figure 2 or on a moveable control panel at the loading position. For positioning of emergency stop control see 5.1.5.
