1. The user demands the enabling of the guard locking device. The “UNLOCK_CMD” signal
changes from logic “0” to logic “1”, while the “O
UT” signal changes from logic “1” to logic
“0”.
2. The guard locking device is controlled as parameterized with the “U
NLOCK” delay time
of 0.5 s. The “L
OCKOUT” signal changes from logic “0” to logic “1”.
3. The guard locking device is activated with a delay of 95 ms, which is determined by the
technical properties of the guard locking device. With 95 ms, the actual time is below
the parameterized time of 100 ms.
4. The guard locking device is enabled and the user opens the safety door. The “G
ATE”
signal changes from logic “1” to logic “0”.
5. The user closes the safety door and the “G
ATE” signal changes from logic “0” to logic
“1”.
6. The user releases the control that enables the safety door. The “GUARD-LOCKING”
operator uses the “L
OCK_FBK” signal to detect the closed door and controls the blocking
of the interlock. The “L
OCKOUT” signal changes from logic “1” to logic “0” as does the
“U
NLOCK_CMD” actuation signal.
7. The guard locking pin feedback is returned with a delay of around 95 ms, which is de-
termined by the technical properties of the guard locking device.
8. As soon as the “GUARD-LOCKING” operator detects that the guard locking device is
in the locked position and the door is closed, the “O
UT” signal is set to logic “1”.
