Tables 1 and 4; fencing shall have a minimum height of 1.40 m and comply with
EN 1034-1:2000+A1:2010, 5.1.3;
— pressure-sensitive safety devices in accordance with EN 1760-1:1 997+A1 :2009, EN 1760-2:2001 +A1 :2009 and EN 1760-3:2004+A1:2009;
— electro-sensitive protective equipment type 4 in accordance with EN 61496-1:2004 at the roll-in and roll-out areas where these areas can be accessed to reach the danger zone (for examples of muting systems see Annex B and EN 619:2002+A1:2010, Annex F);
interlocking movable guard;
— locating the in-feeding or out-feeding conveyor(s) at a height of at least 1.00 m above level of access and complying with the safety distances EN 349:1993+A1:2008 and safety distances according to EN ISO 13857:2008, Table 1 and Table 4.
EN ISO 13855:2010 shall be complied with. The related control system shall comply with at least EN ISO 13849- 1:2008, Performance Level PL c or EN 62061:2005, Safety Integrity Level SIL 2.
5.8 Rotating device with carrying rolls
5.8.1 On rotating devices with carrying rolls, the inrunning nips between the carrying rolls and the machine frame shall be avoided by designing the gap as small as possible and with a maximum of 8 mm.
5.8.2 Drawing-in points between paper rolls and the carrying rolls shall be safeguarded by safety devices In
accordance with EN 1034-1:2000+A1 :2010, 5.1 and 5.4, for example pressure-sensitive devices according to
EN 1760-1:1997+A1:2009. The related control system shall comply with at least
EN ISO 13849-1:2008, Performance Level PL c or EN 62061:2005, Safety Integrity Level SIL 1. EN ISO
13855:2010 shall be complied with.
5.9 Transfer points for industrial trucks
5.9.1 On sites where industrial trucks are used to take rolls from a conveying system, for example a conveyor, or to put them on the conveyor, provisions shall be made to inhibit automatic start-up of the conveying system while the roll is being transferred. Appropriate measures are for example induction loops provided en the floor or photoelectric curtains which prevent the conveyor from starting if the presence of an industrial truck is detected. The related control system shall comply with at least EN ISO 13849-1:2008, Performance Level PL b or EN 62061:2005, Safety Integrity Level SIL 1.
5.9.2 Driverless trucks used for handling rolls shall comply with EN 1525:1997. In the area where rolls are
transferred to driverless trucks, measures and devices are required in accordance with EN 1525:1997, 5.9.5.6.
5.9.3 The conveyor on the transfer-points for trucks shall not be higher than 1,5 m.
5.10 Interfaces/transfer points to adjacent conveying systems, the delivering machine and the receiving machine
5.10.1 Where roll handling systems are split up into sections operating under a joint safety device, and where an individual section needs to be accessed with the guard open while the adjacent area is active, provisions shall be made to ensure that the safety system for the active area is maintained, for example by a temporarily active trip device on the interface/transfer point.
5.10.2 On the interfaces/transfer points between the roll handling system and the delivering machine or the receiving machine, rolls shall be prevented from causing the safety system of the delivering or receiving machine to be defeated.
NOTE This may require manufacturers of roll handling systems and the manufacturers of delivering arid receiving machines to work together, for example for finding a common definition of the interface, installation of muting systems, General information on muting systems is given in Annex B.
5.11 Emergency stop device
5.11.1 Roll handling systems shall be provided with an emergency stop device in accordance with
EN 1034-1:2000+A1:2010, 5.7 and EN ISO 13850:2008.
5.11.2 Emergency stopping shall act on the entire intertinked roll transport system, including the conveyor of the delivenng machine and the feeding conveyor of the receiving machine.
5.11.3 The control system shall contain interfaces to ensure that the delivery conveyor of the delivering unit is included in the emergency stop circuit of the delivering unit and the feeding conveyor of the receiving unit in the emergency stop circuit of the receiving unit.
NOTE This may require manufacturers of roll handling systems and manufacturers of the delivering or receiving units respectively to work together.
5.11.4 The control system relating to the emergency stop function shall comply with at least EN ISO 13849-1:2008. Performance Level PL c or EN 62061:2005, Safety Integrity Level SIL 1.
5.11.5 Where interlinked roll handling systems extend over two or more floor levels or rooms of the building, risk assessment may reveal that more than one emergency stop device is required and, in deviation from 5.11.2, a particular emergency stop device may not need to stop all the machinery..
