Festo — MS6(N)-SV-...-E-10V24 — 2021-11e

Product overview

Fig. 6: Connection with NECA-…-MP3

static enable signals with opposite potentials

Time delay of the level change of the enable signals is monitored

Behaviour on detection of a cross circuit:

Product in exhausted status: remains in safe status and switches to malfunction

Product in pressurised status: switches to safe status and to malfunction

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.
