Safety Interlock Relay
Relay A on each EMSwitch plug-in card can be used as a safety interlock relay.
As long as the connector is shorted (by an external interlock switch), the relay
can be activated. However, as soon as the interlock circuit opens, relay A will
return to the idle position.
Note: If you do not want to use this relay as a safety relay, the
connector must be shorted in order to use it as a standard relay.
When the safety interlock relay is activated, the power supply to the first relay of
the card will be interrupted (fully hardware controlled), causing the relay to switch
to the normally open position. The EMCenter will detect this interlock status and
display a message. For safety reasons, the software is not able to overrule this
interlock condition.
After the interlock has been closed again, the relay will switch automatically to its
original condition.
