Input “GATE” The input monitors the position of the safety door (closed/open). This signal is generated by
the “GUARD-MONITORING” function block and applied to the “G
ATE” input.
The position of the safety door is detected externally via signal B1 (11-12) using the
“GUARD-MONITORING” function block. Provided the safety door is in the closed position,
the “G
ATE” signal is logic “1”.
Input “U
NLOCK_CMD” The “UNLOCK_CMD” input demands the signal for the release of the guard locking device by
the user. Specifically:
– - Logic “1”: “Unlock guard locking device” demand
– - Logic “0”: “Lock guard locking device” demand
For example, the control command can come from a button. Link this button signal to the
other enable conditions to unlock the guard locking device (e.g., zero-speed signal or safe
position signal).
Output “O
UT” The “OUT” output is used to enable the actuators.
Output “L
OCKOUT” This signal controls the electromagnets of the guard locking device and can assume the val-
ues logic “0” and logic “1”.
Output “E
RROROUT” The output signals an error in the control of the guard locking device with logic “1”. Other-
wise, a logic “0” is present at this output.
Operating modes (general description)
The “GUARD-LOCKING” operator checks the plausibility between the “U
NLOCK_CMD” con-
trol signal, the status of a door/gate (“GUARD-MONITORING”), if present, the “G
ATE” sig-
nal, and the status of the electromagnets via the “L
OCK_FBK” signal. The “OUT” output as-
sumes the value logic “1” if the interlock is closed and blocked.
Value Meaning
OUT
1
– Door/gate closed
– Guard locking device is in the locked position
0
– User request to unlock the guard locking device is pending
– Plausibility error
