The control system of the emergency stop device shall comply with the requirements of 5.2 and the control system of the start-up warning device shall comply with the requirements of 5.3. 5.7.2 For the control systems of interlocking devices of chucking or supporting systems of chucking cones, the following categories are suitable: a) category 3 according to EN 954-1:1996 where there is a risk of non-limited ejection of reels in case of loss of the safety function; b) category 1 according to EN 954-1:1996 where a mechanical safety device is provided to contain the reel ejected in case of loss of the safety function. 5.8 Noise The requirements of 5.15 of EN 1034-1:2000 shall be satisfied. The noise emitted from the sheeter unit and the connecting elements of the trim suction device shall be reduced by the measures defined in 5.15.1 of

EN 1034-1:2000. 5.9 Integrated lighting The requirements of 5.18 of EN 1034:2000 and EN 1837 shall be satisfied. 5.10 Ergonomic principles The requirements of 5.22 of EN 1034-1:2000 shall be complied with. Special consideration shall be given to the following operations of the work process: a) inserting the reel in the unwinding unit; b) removal of run-down tubes or reel shells; c) web threading; d) waste removal; e) removal of test sheets; f) adjustment of sheet lays in the belt section; g) adjustment of jogging plates of the sheet collating device.

EN 1034-5:2005 (E) 13 5.14 Unwinding unit 5.14.1 Reel shells and frame supports shall be designed such that reels and frames can be installed safely and unintended ejection is prevented. Safe installation is ensured, for example, by providing an inclined separating line of the support so that the reel or frame automatically moves into the support. Unintended ejection is prevented, for example, by providing support covers or adequately dimensioned support walls. 5.14.2 Reel shells and frame supports shall be designed such that the removal of reels or reel frames is prevented if the support cover is closed or the clutch engaged. Facilities that prevent removal of reels and frame supports when the support cover is closed are, for example, deflecting bars or guards on the support cover and on the clutch so that insertion of the crane hook is prevented. 5.14.3 Core chucks of unwinding units with shaftless winding shall not be allowed to move apart under the control of the respective control device if: a) the reel is lifted and b) the winding motion is switched on. Suppressing the interlocking function required for condition a) by means of an enabling device shall be allowed only where functional reasons require the core chucks to move apart in a position above the required level, for example, for removal of cores. For requirements of interlocking devices, see 5.7.2. 5.14.4 Core chucks of shaftless unwinding units shall only be capable of being engaged with a hold-to-run control if the danger zone is accessible. The control shall be located so that the operator is able to observe to movement. The associated control system shall be at least of category 1 according to EN 954-1:1997.

For automatic reel changing units, further safety measures are required in accordance with 5.14.7. 5.14.5 Drawing-in hazards between the reel and fixed machine parts, cylinders and other rollers shall be prevented or safeguarded for all reel diameters according to 5.4 of EN 1034-1:2000. A drawing-in hazard does not exist where there is a clearance of at least 500 mm between the reel and adjacent rollers, cylinders and beams. Inrunning nips which are located at a height of 2,0 m to 2,5 m above a possible level of operation can be safeguarded by providing a clearance of at least 300 mm; the instruction handbook shall then contain the information that no any access steps or other means of access shall be used. For the inrunning nip existing between reel and floor, the following measures can be applied, depending on the results of risk assessment according to EN 1050:1998:  clearance of > 500 mm between reel and floor;  safety devices in accordance with 5.4 of EN 1034-1:2000;  safety devices in accordance with 5.1.1 of EN 1034-1:2000;  safety measures in accordance with EN ISO 12100-1:2003. The instruction handbook shall in addition point out that marking the floor area beneath is required according to clause 7 and it is not permitted to creep beneath the reel.

Different or additional safety measures are possibly required for unwinding units with automatic reel changing facility in accordance with 5.14.7. 5.14.6 Where crushing and shearing points between the machine frame and the winding arms cannot be designed out, winding arms shall only be capable of being moved with a hold-to-run control. The associated control system of this control shall be at least of category 1 according to EN 954-1:1997. The danger zone shall be within the operator's view. Different safety measures may possibly be required for unwindi
