MS6-SV-E with multi-pin plug socket NECA-S1G9-P9-MP5
Note
A cross circuit between the enable signals (EN1/EN2) is not detected and does not
cause an error response. The system can is pressurized only when the enable signals
are applied correctly.
•
Ensure that the cross-circuit detection is established and guaranteed by means of
conforming measures in the peripherals (PLC/safety control) in accordance with
valid safety standards.

Connection with NECA-...-MP5
–
Static enable signals with opposite potentials
–
The time delay of the level change of the enable signals is
not
monitored
–
Behaviour on detection of a cross circuit (through upstream safety switching device/PLC):
•
MS6-SV-E in the exhausted status: remains in the safe status and does
not
go into malfunction
•
MS6-SV-E in the pressurized status: goes into the safe status and does
not
go into malfunction
–
Enable signal are galvanically separated from the supply voltage
