1. Lockout indicator
If the SL-CHS control circuit detects an error, the SL-CHS goes to lockout condition and the status indica-
tor turns orange. At the same time, the OSSD output (or FSD output when the SL-R11 is connected to
the SL-CHS) is turned off and the machine stops.
2. Bar LEDs
Each transmitter and receiver has an 8-segment LED indicator that shows the SL-CHS operation status.
When the paths of all beam axes are clear of any obstruction in the normal state, all LEDs turn green.
When there is some blockage of the beam axes, some of the eight LEDs will turn red to indicate the
percentage of the total beam axes whose light beams are being received.
When receiver cannot get any light from transmitter in spite of no obstruction, the red LED at the bottom
flashes.
3. Output status indicator
This indicates the OSSD output status (or the FSD output status if the SL-R11 is connected to the SL-
CHS Series). When the OSSD (or FSD) output is turned ON, the indicator lights green. When the OSSD
(or FSD) output is turned OFF, the indicator turns red.
Therefore, if the output status indicator is red, the OSSD (or FSD) output is turned OFF and the machine
has been stopped regardless of the functions being used.
4. Function indicator
The function indicator turns orange if each function supported by the SL-R12EX has been enabled. For
details, see the Instruction Manual for the SL-R12EX.
