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:
Note that:
LED ON = contact closed
LED OFF = contact open
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.
ERROR led flashing indicates alarm in
progress (situation does not impair gate
operation)

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.
Leds 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 on with a fixed light indicates
an error in progress (situation that locks
operation until the cause of the error has
been removed)
