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.
WARNING
If crossfault monitoring is deactivated and a dual-channel, equivalent-switching
sensor is used, the MOVISAFE
®
CS..A safety card
cannot
detect crossfaults in the
cabling.
Severe or fatal injuries.
•
Make sure that crossfaults are not possible at the safe digital inputs F-DI.
INFORMATION
Note that in the non-equivalent connection variant, the NC contact is connected to
the sensor supply F-SS0.
8.5.7
Active sensors (dual-channel)
When connecting a dual-channel sensor with additional voltage supply, the voltage is
supplied via an external DC 24 V power supply. The voltage supplies for the sensor
outputs are connected to the sensor supply F-SS0 and F-SS1. The safe outputs of the
sensor are connected with 2 channels to the respective safe digital inputs (F-DI.) at
terminal X60. Note the detailed assignment of the safe digital inputs (F-DI.) to the
sensor supply F-SS0 and F-SS1 in chapter "Terminal assignment".
Settings in the parameterization tool "Assist CS..":
•
Choose the dual-channel connection type (equivalent/non-equivalent).
•
Activate or deactivate the pulsed sensor supply, depending on the safety require-
ments.
•
Parameterize the permitted discrepancy time between the two input signals of the
sensor you are using.
