Where a visual aid or protective visor is required for use with the machine, the illuminance shall be multiplied by the reciprocal value of the transmitttance of this device Where the transmittance is unknown the illuminance shall be increased by at least 50 % BS EN 1837:1999+A1:2009 EN 1837:1999+A1:2009 (E) In control cabins or where processes are affected by light, the above illuminance may be reduced !NOTE Lighting controls can be helpful for increasing and reducing the illuminance level, e.g by dimming or switching or by mechanical adjustment." 4.3 Glare The integral lighting system shall avoid direct glare both to the machine operator and other workers in adjacent areas Any reflected glare shall be avoided as far as possible NOTE It is possible to achieve this by suitable shielding of the lamp(s), by location and direction of the luminaire(s), and by the use of light, matt surface finishes 4.4 Directionality The lighting system shall be designed and adjusted to avoid disturbing shadows on the visual task The directionality of the lighting shall ensure a perception of form which is appropriate for the visual task 4.5 Colour quality The colour rendering properties and colour appearance of the lamp(s) shall be suitable for colour discrimination of the visual task and for operator comfort 4.6 Stroboscopic effect The lighting system shall be designed to avoid stroboscopic effects which can lead to dangerous situations by changing the perceived motion of rotating or reciprocating machinery NOTE This can usually be achieved for example by use of DC electrical supply for incandescent lamps, or by operating incandescent or discharge lamps at high frequencies (around 30 kHz) ! 4.7 Ergonomic principles Ergonomic principles shall be taken into consideration for integral lighting systems of a machine e.g adjustable luminaires shall be stable in their position, but easy to move if necessary, particularly if changing from seating to standing position; actuators shall be adequate for the intended use 4.8 Emergency lighting Emergency lighting shall be provided in large machines that may be operational at times when the supply to the normal lighting of the machinery has failed (see EN 1838)." 5.1 Lighting equipment and installation Lamps Lamps shall be chosen to be safe in operation and not present a hazard to the machine operator BS EN 1837:1999+A1:2009 EN 1837:1999+A1:2009 (E) NOTE It is advisable that in general lamps are enclosed to protect the operator from injury caused by e.g damaged lamps, excessive heat or emission of harmful radiation 5.2 Luminaires Luminaires shall be designed to: a) provide the required lighting on the task, b) minimize the accumulation of dirt on lamps and optical surfaces, c) minimize premature ageing of optical elements, d) !facilitate ease of service, particularly ease of cleaning," e) comply with EN 60598, f) be compatible with the machine, for example withstand vibration, radiation, etc !NOTE Safety requirements for luminaires are provided in other standards, particularly in EN 60598-1 NOTE Some additional requirements of luminaires can be found in other standards (e g for protection classes in EN 60529)." 5.3 Installation Luminaires shall be mounted in such a way as to: a) provide the required lighting on the task; b) avoid interference with the task and hazard to the operator; c) minimize the accumulation of dirt on lamp(s) and luminaire(s); d) facilitate ease of service Examples showing the principles of some possible solutions are given in the informative Annex A 5.4 Availability of illumination Where failure of the integral lighting system of the machine can give rise to dangerous conditions the lighting system shall consist of more than one light source One of these sources shall be supplied from an alternative electrical supply 5.5 Electrical supply The lighting system shall be connected to the electrical supply so that it is capable of operation even when the machine is switched off Verification procedures The manufacturer of the machine with integral lighting shall: a) measure the illuminance and check the uniformity surroundings ( E / E ) in the task area and the immediate BS EN 1837:1999+A1:2009 EN 1837:1999+A1:2009 (E) Illuminance should be measured with an illuminance-meter having a cosine and V (λ) corrected photocell, b) check by visual inspection that glare control, directionality, colour properties and stroboscopic controls are satisfactory, c) provide a test report of the lighting system, !NOTE The test report should include all relevant data, e g.: - average illuminances in the task area(s) and in the immediate surrounding area(s) and the uniformities of the illuminances in these areas; - the positions of the luminaires in or at the machine; - confirmation that there is no disturbing glare under intended use conditions; - confirmation that there is no flicker and no stroboscopic effects under intended use conditions; - description of the intended use conditions." d) supply a testing and maintenance schedule !The performance of the lighting system shall be checked regularly, at least once a year, in accordance with d) and appropriate action shall be taken The lighting system shall be cleaned and maintained as given in the machine's maintenance schedule in accordance with d)."
