GUARD LOCK OPERATORS (max number = 4)

GUARD LOCK

The "GUARD LOCK" operator is designed to
control locking/unlocking of an
ELECTROMECHANICAL GUARD LOCK in a variety
of operating contexts.
Parameters
Manual Reset:
There are two types of reset: Manual and Monitored. When Manual is selected the system only
verifies the signal's transition from 0 to 1. If Monitored is selected the double transition from 0 to
1 and then back to 0 is verified.
Unlock Time (s):
The time that must pass between the UnLock_cmd input reaching and the real guard unlock (Lockout
output).
-
0ms...1 s Step 100 ms
-
1.5 s...10 s Step 0.5 s
-
15 s...25 s Step 5 s
Feedback Time (s):
Maximum delay accepted between LockOut output and Lock_fbk input (must be the one shown on the lock
data sheet with appropriate gap decided by the operator).
-
10ms...100 s Step 10 ms
-
150ms...1 s Step 50 ms
-
1.5 s...3 s Step 0.5 s
Interlock Spring: The guard is locked passively and released actively, i.e. the mechanical force of the spring
keeps it locked. The guard thus continues to be locked even when the power supply is disconnected.
Mandatory gate opening: Only with door opening and subsequent confirmation of input GATE, the cycle
proceeds.
Gate not present: If selected, enables configuration without Gate but only with LOCK FEEDBACK (feedback
coil lock).
Enable error out: This can be selected to enable a signal (Error Out) to indicate a lock malfunction. When
Error Out = 1 (TRUE) there is a fault in the lock. (e.g. open door with guard lock locked, Feedback Time
exceeding the maximum allowed, etc.).
