Light barrier
Features of the light barrier
Different beam lengths The light barrier is available with two different beam lengths:
– 0.5 m - 18 m
– 15 m - 70 m
Effectiveness
The light barrier is only effective in the AUTO operating mode. If the op-
erating mode switch is set to the MAN or 0 position, the light barrier will
not be effective.
Operating mode indica-
tion The signal tower has three lamps used to indicate the operational states:
Color Meaning
green The light barrier is active and not interrupted. The
CMM moves at the speed defined in the measurement
plan.
white The light barrier is not active. The MAN or 0 operating
mode has been selected.
Blue EMERGENCY STOP has been triggered.
Functions of the light barrier
The light barrier may have two functions: EMERGENCY STOP and REDUC-
TION . The required light barrier function must be set by a ZEISS service
engineer during the start-up of the light barrier. It is not possible to
switch between the two functions.
Option 1: EMERGENCY STOP function
An EMERGENCY STOP is activated when the light barrier is interrupted.
The drives are switched off and all travel movements are stopped. The
current measurement plan is interrupted and may need to be restarted
later if necessary.
Restarting As soon as the light beam is no longer interrupted, the light barrier is ac-
tive again.
– Switch on the drives.
Option 2: REDUCTION function
