1-1 Features
The F3SP has two independent microprocessors forming a "dual system" and can be
used up to system with safety category 4.
One or two light curtains can be input to the F3SP, and input state will be displayed with
four input indicators (Green LEDs).
When one or both safety light curtains are interrupted, the F3SP opens both safety
output contacts.
Status indicator (7-segment display) supplies information on the state and on probable
failures.
The F3SP has both muting and override function, which forces system operation not
relate to light curtain status.
The muting function makes it possible to inactivate one or both light curtains in order to
allow, for instance, the objects passage without stopping the machine.
The override function allows the system to be manually overridden allowing material to
be cleared from the muting area if a fault has occurred.
Both the muting and the override functions force the system to work. Therefore,
activating these functions needs some precautions to avoid the reduction in safety
(Please refer to section 4-2 and 4-3).
