In addition, they shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant, which are not dealt with by this document (e.g. sharp edges). The safety related parts of the control system shall present at least a performance level “c” in accordance with EN ISO 13849-1. 5.2 Mechanical hazards 5.2.1 General The interlocking devices shall be built inside the machine housing and shall comply with EN ISO 14119:2013, 4.2 and Clause 7. After activating an interlocking device the stopping time of the blade shall be ≤ 0,15 s. Hazardous after-run of tools shall be prevented by braking devices or other solutions with equivalent effect. Braking devices shall become automatically effective upon switching off the drive and in the event of a voltage failure and upon opening of the protective devices. SIST EN 13871:2015

If the enclosing guard (e.g. cutting chamber door, protective hood) is open, the sickle blade shall be prevented from any unintentional movement. It shall be stated clearly in the instruction for use that “Cut-resistant gloves shall be worn” when changing the cutting tools and when carrying out any work in the vicinity of the cutting tools. 5.2.2.5 Zone 6 – Drive mechanism Access to danger points at the drive mechanism shall be safeguarded by the provision of fixed or interlocked movable guards as defined in EN 953:1997+A1:2009, 3.2 and 3.5. If guards need to be opened for changing the operating process or for cleaning purposes, they shall be interlocked. The interlocking system shall be according to 5.2.1. 5.2.3 Cubes cutting machine with feed intake hopper and loading device 5.2.3.1 Zone 1 – Feed intake hopper with automatic driven closure gate Access to the danger points at the closure gate shall be prevented. This shall be achieved e.g. by the following measures: Access is prevented by: — the design (e.g. closed feed intake hopper) including a closed loading device for products (e.g. screw conveyor, pipeline with pump) (see 5.2.3.2.1) or SIST EN 13871:2015

There are no danger zones in the tilt range if the distance between the load bearing device and the mast is > 120 mm. If the tilt range of the load bearing device is > 2 000 mm or more above the floor, there are no danger zones if this distance is > 60 mm. 5.2.3.13 Zone 5 – Lift-tilt device for feed heights > 2 500 mm The path of movement of the load bearing device, with the exception of the run-in and run-out opening, shall be protected by means of a distance guard (e.g. a protective fence). An electro-sensitive protective device (e.g. a light barrier, mechanical bar or flap) shall be fitted on the upper edge of the run-in and run-out opening to prevent lifting of incorrectly positioned trolleys or containers. For requirements relating to the interlocking system of the mechanical bar or mechanical flap as well as the light barrier, see 5.2.3.2. 5.2.3.14 Zone 5 – Lowering velocity of load bearing device The lowering velocity shall be ≤ 0,4 m/s when it is controlled by a hold-to-run switch. The lowering velocity shall be ≤ 0,1 m/s if the descent is controlled automatically or by a switch with a locking contact. In this case the last 0,5 m until the transport trolley or container has touched down shall be controlled by a hold-to-run switch. 5.2.3.15 Zone 6 – Drive mechanism See 5.2.2.5. SIST EN 13871:2015
