Verification: By checking the relevant drawings and/or circuit diagrams, inspection of the machine, measure-ment 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 All hand-operated controls shall be located at a height between 600 mm and 1800 mm above floor level. The controls for starting the saw blade spindle drive motor, normal stopping, mode selection (where fitted) and integrated feed of the work piece (where fitted) shall be located together on the machine or on a mobile con-trol desk from which there is a view possible to the loading position (for electrical drives see also 11.2.1 of EN 60204-1:2006). Where controls are located on a mobile control desk the following requirements shall be met: a) it shall be connected by cable to the machine; b) its position shall be indicated in the instruction handbook. Where the machine is fitted with a two-hand control device it shall be: 1) situated at the front of the machine so that one of the manual control actuators is located on one side of the cutting line and the other manual control actuator on the other side of the cutting line (see Fig-ures 2, 3 and 4); 2) below the work piece support; 3) at a minimum height above floor level of 750 mm. Where the control for the powered work piece clamping is separate from the two-hand control device it shall be within 400 mm measured horizontally to the two hand control. According to the size of the machine, emergency stops required by 5.2.5 shall be positioned: i) within 1,0 m of the loading position; ii) within 1,0 m of the unloading position;
iii) at the main control panel; iv) within 500 mm of the two-hand control device (where provided); v) within 3,0 m of the saw unit. SIST EN 1870-10:2013

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. Closure of movable interlocked guards shall not lead to an automatic restart of hazardous movements. For semi-automatic machines the cutting stroke shall only be capable of being started with a hand-operated control device after saw blade rotation and powered work piece clamping have been initiated. For all machines the cutting stroke shall only be capable of being started when: a) saw blade rotation and powered work piece clamping (where fitted) have been initiated; b) all interlocked guards are in the closed position; c) no person is standing on pressure sensitive mats (where provided); d) no person is within the beams of an active optoelectronic device (where provided). For electrically operated machines see the requirements of 9.2.5.2 of EN 60204-1:2006 but the exceptions described in 9.2.5.2 of EN 60204-1:2006 are not relevant. SIST EN 1870-10:2013

EN 61800-5-2:2007. When actuated the emergency stop shall disconnect power from all machine actuators and actuate the brake (if provided). When initiated the stopping sequence shall: a) initiate the return stroke of the saw unit; b) remove power to work piece clamping (where fitted); c) cut power to saw spindle motor and initiate the brake (where fitted); SIST EN 1870-10:2013
EN ISO 13849-1:2008. For the cutting stroke of the saw unit see 5.2.3.
