clocked enable signals (EN1/EN2 = 24 V) for detection of shorts across contacts.
Detection of shorts across contacts by clock signals is always carried out by the safety relay
unit/safety PLC.

The clock outputs of different controller manufacturers are not standardised. The usability must be
checked in every case. If the clock pulse is outside the described limits, this is recognised by the
product as an error and a safe switch-off is carried out.
MS6-SV-E with multi-pin plug socket NECA-S1G9-P9-MP3
The multi-pin plug socket NECA-S1G9-P9-MP3 is intended for conventional circuitry with electromech-
anical safety relays. If problems arise in use with bipolar semiconductor outputs, use the multi-pin
plug socket NECA-S1G9-P9-MP5.

–
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
