MS6-SV-E with multi-pin plug socket NECA-S1G9-P9-MP5
NOTICE!
A cross circuit between the enable signals EN1/EN2 is not detected and does not cause an error
response. The system is pressurised only if the enable signals are applied correctly.
•
Ensure that detection of shorts across contacts is established and guaranteed by corresponding
measures in the peripherals (PLC/safety control) in accordance with the valid safety standards.
Fig. 8 Connection with NECA-…-MP5
–
static enable signals with opposite potentials
–
Time delay of the level change of the enable signals is not monitored
–
Behaviour on detection of a cross circuit (through upstream safety relay unit/PLC):
–
MS6-SV- E in exhausted status: remains in safe status and does not go into malfunction
–
MS6-SV- E in pressurised status: goes into safe status and does not go into malfunction
–
Enable signals are galvanically separated from the supply voltage
