Product overview

– 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 (by 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

Switching statuses
The time delay t2 between EN1 and EN2 must be automatically defined. The duration of the delay
is not evaluated. The multi-pin plug socket NECA-MP5 does not enable the product to detect shorts
across contacts.
Signal contact
The signal contact is a potential-free N/O contact of a semiconductor relay. The contact can be picked
up in the feedback circuit of a safety control system through terminals 3 and 4 of the NECA multi-pin
plug socket as required.
