A selector switch provides the possibility to choose between operating mode with activated protective
field of the AKAS® and fast closing speed or operating mode with protection only by monitored slow
speed closing, see
Wiring diagrams 8/S.32 und 9/S.32
. If the selector switch is activated, the protective
field of the AKAS® is muted (bridged). This state is displayed by the shining muting lamp. By disabling
of its
output
SGA
, AKAS® requires the NC to carry out only cycles in slow speed, which is monitored
by the AKAS®. Given the fact that in this operating mode, only cycles in slow speed are possible, the la-
teral protective grids are not monitored. Every switching-over of the selector, the reset buttomn must be
activated for the Emergency-OFF circuits and the circuits of the lateralprotective doors.
