| • The monitored muting lamp is connected to Y1 and Y4. A power consumption of min. 3.6 W and max. 60 W is condition, since this is monitored by the safety circuits. The muting lamp is illuminated to show active muting function. • The muting sensors (A, C and B, D) are connected to the terminals S11-S12 and S22-S23. The muting sensors must be switched in the following sequences: A; B; C; D or D; C; B; A. There must be a time difference of at least 0.5 s between actuation of the muting sensors and that of the safety light grid. • SCR 1R to monitor a feedback circuit for Control Category 4 to EN 954-1 • Safety light grids/curtains to guard dangerous areas • The feedback circuit monitors the positions of the positive-guided NC contacts on the conactors K6 and K7. • Start push button © A start push button can be connected to the feedback circuit. If no start push button is mounted, the terminals X2 and X3 must be bridged. |
