Page 3: Warning
EC machine directive 89/392. WARNING The MINERVA safety system consists of one or two pairs of photocells connected to the standard control unit AU S3, the control unit with integrated muting function AU S3M2 or the control unit AU S-TWIN (up to four pairs of photocells). To gain an understanding of... -
Page 4: General
GENERAL MINERVA is a barrier type photocell consisting of a separate emitter and receiver. When it is connected to the standard control units AU S3, AU S-TWIN or the integrated unit with muting function AU S3M2, MINERVA represents a type 2 safety system for the protection against accidents of people exposed to hazards on dangerous machinery. -

Page 8: Installation
INSTALLATION The MINERVA photocell system used in conjunction with a AU S3, AU S-TWIN or AU S3M2 control unit represents a type 2 electro-sensitive safety protection system. As provided for by international standards 61496-1 and prEN61496-2, in type 2 safety devices, possible faults or malfunctioning must be detected during the testing stage. -

Recommended Fc factors are listed in the table below: ENVIRONMENTAL CONDITION CORRECTION FACTOR Fc Mist 0,25 Vapours 0,50 Dust 0,50 Dense fumes 0,25 SAFETY DISTANCE AND POSITIONING The photocell must be installed at a distance greater than or equal to the minimum safety distance, S, so that no hazardous point can be reached until the hazardous action of the machine has stopped (fig. -
Page 10: Single Beam Protection
Figure 4 Double beam protection Through the use of two overlapping MINERVA photocells with the two beams aligned one on top of the other it proves possible to create a double beam protection set-up. In this case, the minimum safety distance must be calculated from the following formula:... -
Page 11: Distance From Reflecting Surfaces
Figure 5 Multiple systems When using 2 pairs of MINERVA systems, whether placed side by side or one on top of the other, make sure they do not interfere with one another by arranging the elements so that the beam emitted by the emitter of either system is received only by the... -
Page 12: Use Of Deflector Mirrors
Use of deflector mirrors For the protection and control of areas that can be accessed from several sides, in addition to the emitter and the receiver you can also use one or more deflector mirrors. Deflector mirrors, in fact, make it possible to reflect back on several sides the optical beams generated by the emitter. -

Page 18: Mechanical Assembly And Optical Alignment
Connection of two pairs of photocells with AU S3 unit or AU S3 M2 muting unit Mechanical assembly and optical alignment The emitter and the receiver must be assembled one in front of the other at a distance not to exceed the effective capacity of the equipment, by means of the fastening brackets (page 6) supplied as standards: for the assembly of the latter see fig. -
Page 19: Checking And Maintenance
Figure 9 CHECKING and MAINTENANCE The MINERVA photocell must be used within the operating temperature parameters given in the technical data. Before each work shift or power-up, verify the correct operation of the photocell through the following procedure: intercept the beam by means of a non-transparent cylinder shaped object with 12 mm diameter, to be placed first in the centre of the area between the emitter and the receiver, and then close to both components. -
