switches from LL0 to LL1.
(3) At this time the electromagnet is actually activated, 95ms after the command was
sent. This delay is due to the technical characteristics of the electromagnet. In any
case, 95ms is less than100ms ("Feedback Time") and so no errors have occurred.
(4) At this time the guard lock is unlocked and the user opens the gate, the FBK_GATE
signal switches from LL1 to LL0.
(5) At this time the user closes the gate and the FBK_GATE signal thus switches from
LL0 to LL1.
(6)
the gate closed condition, via the FBK_GATE signal, and sends a command to lock
