CHECKING
THE
LEDS
After
making all the connections and powering the board, check the
status
of the leds against the
status
of the inputs
in the following table (in
Fig.
6, the condition where the
automated
system
is
closed in stand-by).
These LEDs
indicate the
status
of the board inputs and are of considerable
importance
to
automated
system
move-
ment:

The inputs
STOP,
FSW CL, FSW OP
are
safety
inputs with
a N.C. (Normally Closed)
contact and the corresponding leds must
therefore be ON; where the
automated
system is
in stand-by, they
will
go off when
the connected device
is
engaged.
The inputs OPEN A, OPEN B/CLOSE
are inputs
with a N.O. (Normally Open) contact
and
the corresponding leds must therefore
be
OFF; where the automated system
is
in
stand-by, they
will
come on when the con-
nected device
is
engaged.

eds
FCA
and
FCC
represent the N.C. contacts of the limit
switch built into the board that open when
engaged and
turn off the associated
led:
ERROR
led flashing indicates alarm in
progress (situation does not impair
gate
operation)
ERROR
led on with a fixed light indicates
an error in progress (situation that locks
operation until the cause of the error has
been removed)
