Figure 116 shows the traces relative to the operation. These are described in detail below:
(1) At this time the user requests to unlock the guard lock. The “COMMAND” signal
switches from LL0 to LL1, and the “OUTPUT1” signal switches from LL1 to LL0.
(2) At this time the electromagnet is activated with a delay of "Unlock Time", after the
command is sent. This delay has been set to 0.5 seconds. The “ACTIV.” signal
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) At this time the user releases the unlock gate command. The “Guard Lock” detects
the gate closed condition, via the FBK_GATE signal, and sends a command to lock
the guard lock. The “ACTIV.” signal switches from LL1 to LL0.
(7) At this time the electromagnet is actually deactivated, approx. 95ms after the
command was sent due to the technical characteristics of the device. The guard lock
is now locked.
(8) As soon as the “Guard Lock” operator detects that the guard lock is locked and the
gate is closed, the “OUTPUT1” signal switches to LL1.
