MODULAR SAFETY INTEGRATED CONTROLLER MOSAIC
Example of operation in the "no Gate" mode
switch
The guard lock used in the example continues to be locked when the electromagnet is
not energised. Therefore the "Interlock spring" option must be selected.

The Guard Lock operator parameters are shown on the right. On the left there is an
example of an application diagram. The electromagnet feedback consists of two
contacts, one normally closed and one normally open. When the electromagnet is
energised the two contacts switch status.
Figure 60
shows the traces relative to the operation. These are described in detail below:
(1)
(2) At this time the electromagnet is activated with a delay of "Unlock Time", after the
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 than 100ms ("Feedback Time") and so no errors have occurred.
(4)
(5) 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.
