32、ctive measures of this clause. In addition, the machine shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant which are not dealt with by this European Standard (e.g. sharp edges). For applications of a B-level standard such as !EN ISO 13850“, EN 953,

33、 !EN ISO 13849-1“, EN 982, EN 983, EN 1037 and EN 60204-1, the manufacturer shall carry out an adequate risk assessment for the require-ments thereof where choice is necessary. This specific risk assessment is part of the general risk assessment relat-ing to the hazards not covered by this European

34、Standard. Where the means of reducing the risk is by the arrangement of the installed machine or by a safe system of work, the manufacturer shall include in the information for use a reference to the reduction means to be provided, includ-ing training, and to any limiting value of the requirement an

35、d if appropriate to the means of verification. 5.2 The danger zones caused by the movement of loading and stacking mechanisms with or without flat glass, moving and rotating platforms for stillages and the travelling movement of the machinery shall be safeguarded by: 5.2.1 Perimeter fencing with a h

36、eight not less than 1,4 m mounted in a horizontal distance to the danger zone according to !EN ISO 13857:2008, Table 1“ but not less than 0,5 m with an interlocking access gate with or without guard locking guard locking shall be applied if access to the danger zone is possible within the stopping t

37、ime or if the design of the control demands that stopping shall be realised at reference points so as to allow to re-start easily. Using guard locking, the opening of the guard shall only be possible after standstill, or 5.2.2 !electro-sensitive protective equipment employing active opto-electronic

38、protective devices, detecting intrusion of the whole body in the danger zone. These devices shall be in accordance with EN 61496-1:2004, type 4, and CLC/TS 61496-2 with two separate beams in accordance with EN 999:1998, 6.1.4, positioned at a minimum safety distance S = 1 600 T + 850 mm. The beams s

39、hall be mounted at a height of 0,4 m and 0,9 m above floor level. A device with one single horizontal beam can be used if a risk assessment concludes, after taking account of the risk level in the danger zone, the possibility for bypassing a single beam and the possible reasons for such bypassing, t

40、he risk is low. The single beam shall be mounted at a height of 0,75 m above floor level and at a minimum safety distance S = 1 600 T + 1 200 mm in accordance with EN 999:1998, 6.1.5, or“ 5.2.3 !a fixed distance guard (see EN 953:1997, 3.2.2) closer to the machinery with a height not less than 1,4 m

41、 with a movable interlocking guard for access with or without guard locking according to EN 953:1997, 3.3, 3.5 and 3.6, and with minimum safety distances according to EN ISO 13857:2008, Table 1, where there is no free space (room) to use methods of 5.2.1 or 5.2.2.“ Guard locking shall be applied if

42、access to the danger zone is possible within the stopping time or if the design of the control demands that stopping shall be realised at reference points so as to allow to restart easily. Using guard locking opening of the guard shall only be possible after stand-still. NOTE 1 Risks by glass fallin

43、g out laterally or ejected glass see 5.10. NOTE 2 Combinations of 5.2.1 or 5.2.3 with 5.2.2 also are possible. 5.2.4 Perimeter fencing in accordance with 5.2.1 and fixed distance guards in accordance with 5.2.3 shall be drawn to the floor. There may be a gap of maximum 0,15 m between guard and floor

44、 for the purpose of cleaning. 5.3 !The parts of the control system related to guard interlocking shall as a minimum comply with performance level d in accordance with EN ISO 13849-1:2008 (see also examples in informative Annexes B and C). Where fixed guards are used, their fixing systems shall remai

45、n attached to the guards or to the machinery when the guards are removed.“ 5.4 After a stop caused by an interlocking guard or a trip device, a re-closing of the guard or leaving of the light beam shall not initiate a restart but restarting shall require actuation of a switch (reset) at a place with

46、 a good view of the danger zone. This switch shall be mounted in such a way that it is not operable by a person who is within the danger zone (safeguarded area). DIN EN 13035-5:2010-07 EN 13035-5:2006+A1:2009 (E) 10 5.5 5.2 to 5.4 do not apply to the movement of the loading and stacking mechanisms a

47、nd of platforms for stillages if the movement is done by means of a hold-to-run device and the operator has a good view of the danger zone and if there is a distance of minimum 1,8 m between the actuator and the danger zone. NOTE 5.10 and 5.11 are applicable. Where applicable, crushing points betwee

48、n the loading/unloading mechanism and the supporting surface, e.g. ta-ble, conveyor, shall be laid in a distance of minimum 0,5 m from the outer edge of the supporting surface if hold-to-run devices are the only safety measure. 5.6 !The safety-related parts of the control system related to stopping

49、operations initiated by safety equipment (see for example 5.2) shall as a minimum comply with performance level c in accordance with EN ISO 13849-1:2008, e.g. by 5.6.1 de-energizing using contacts (see EN 60204-1:2006, 9.2.2, stop category 0) and applying spring-loaded brakes to motor-driven machines, or NOTE For hydraulic and pneumatic drives: see 5.21.1. 5.6.2 electronically controlled braking and the removal of power using contacts when the stop is achieved, e.g. via a timing element (see EN 60204-1:2006, stop category
