AEG SB4 series- Manuals

SB series User’s manual 9 1 OPERATION The S afety L ight C urtain (SLC) is made up of one bar with transmitting optical elements called Transmitter (TX) and one with receiving optical elements called Receiver (RX). The photosensitive elements are regularly scanned in sequence along all its length. T...

SB series User’s manual 11 If the barriers are installed in a horizontal position, the optical bars must be installed so that the distance that exists between the danger zone and the furthest optical ray is equal to the result of the calculation using the formula, with the following parameters: S = ...

SB series User’s manual 19 4.3 CODES AND SPECIFICATIONS OF AVAILABLE MODELS The columns with “Number of modules” and “Number of optical units per module” refer to operating management with muting (see section 9.3). The following table shows the standard models available in the SBx series, based on t...

SB series User’s manual 21 5 ALIGNMENT PROCEDURE After completing correct mechanical assembly and connections, as described in the previous sections, the SLC should be aligned as follows: • Disconnect the SLC’s power supply. • Open the test/restart contact. • Restore the SLC’s power supply. • Adjust...

SB series User’s manual 23 7 MUTING, OVERRIDE AND FLOATING BLANKING FUNCTIONS 7.1 GENERAL INFORMATION ON THE THREE FUNCTIONS The muting, override and floating blanking functions enable the barrier (or a part of it) to be bypassed when it is working for operational requirements. As required by curren...

SB series User’s manual 29 Application with two sensors and single direction for material exit: This muting activation sequence is only available for SLCs with postfix “–MTL” at the ordering code. Dangerous zone SLC B1 A1 D1 D2 D Electrical connection of muting input Muting input B (Yellow – 4) Muti...

SB series User’s manual 33 7.6 OVERRIDE This function makes it possible to override or bypass the system. It is used to start up the machine after the material has interrupted one or more of the SLC beams and to free the protected area from any material that is present in front of the SLC, If a pall...

SB series User’s manual 35 The zone that can be masked will have max 7 optical elements. 2) total optical elements = 105 optical elements available for Blanking = 31 The zone that can be masked will have max 20 optical elements, even if 30% of the total would be 31. 7.7.2 Alternative Blanking possib...

SB series User’s manual 37 7.7.3 Blanking recording procedure To record the object, proceed as follows: 1. Turn the power of the barrier off, 2. Position the object to determine the Blanking area. 3. Connect Muting input A to the 24Vdc. 4. Make sure that the contact of the Test/Reset button is close...
