IMPROPER SYSTEM PERFORMANCE
Ensure independent stop circuit safety relays have mechanically linked contacts that prevent
contact overlapping in the event of a welded contact.
Failure to comply with these instructions could result in death or serious injury.
IMPROPER INSTALLATION OF CE VERSION FF-SB SERIES LIGHT CURTAIN
Use Figure 3-7 wiring diagram to ensure external relay monitoring by the CE version of the
FF-SB Series Light Curtain.
Failure to comply with these instructions could result in death or serious injury.
Two versions of FF-SB Series light curtains exist: an Original version and a CE version. The
CE version may be used instead of an Original. However, an Original version will not work
(red condition) with the circuit illustrated in Figure 3-7.
