Operation with activated crossfault monitoring
The following errors are detected:
•
Crossfault between every digital input line F-DI. and a 24 V supply voltage.
•
Crossfault between a digital input line F-DIx and another digital input line F-DIy,
which is assigned to another sensor supply, if at least the associated switch con-
tact of the other digital input F-DIy is closed.
•
Crossfault between a digital input line FDI and a sensor supply line not assigned to
the input F-DI.
•
Crossfault between a sensor supply line F-SS and a 24 V supply voltage if the di-
gital input F-DI is assigned to the sensor supply and the switch contact belonging
to F-DI is closed.
•
Crossfault between the sensor supply lines F-SS themselves if the switch contact
belonging to the digital input F-DI is closed.
WARNING
The MOVISAFE
®
CS..A safety card cannot detect a short circuit between an F-SS.
sensor supply and an associated safe digital input F-DI. (bridging of the sensor).
Severe or fatal injuries.
•
Make sure that a short circuit between the sensor supply F-SS. and an associ-
ated safe digital input F-DI. is not possible.
