Configuration With Interleaved Proximity
When an axis of the MV modules is configured for a measurement with two proximity
switches, these can be configured in interleaved mode. Under the conditions listed below
the system reaches a Performance Level = PLe:
• Proximity switches must be fitted such that the recorded signals overlap.
• Proximity switches must be fitted such that at least one is always activated.
Figure 10
In addition:
• The proximity switches must be PNP type.
• The proximity switches must be NO type (Output ON when detecting metal).
• With the above conditions fulfilled, the DC value is equal to 90%.
• The two proximity switches must be of the same model, with MTTF > 70 years.
RESTART_FBK
The RESTART_FBK signal input allows the MOSAIC to verify an EDM (External Device
Monitoring) feedback signal (series of contacts) from the external contactors, and to
monitor Manual/Automatic operation (See the list of possible connections in Table 24).
If the application requires it, the response time of the external contactors must be verified by an
additional device.
The RESTART command must be installed outside the danger area in a position where the danger
area and the entire work area concerned are clearly visible.
It must not be possible to reach the control from inside the danger area.
