Output Relays Settings
BO-5 X2
The conditions of module outputs and signals/protective functions (such as reverse interlocking) can be passed
by means of alarm relays. The alarm relays are potential-free contacts (which can be used as opening or
closing contact). Each alarm relay can be assigned up to 7 functions out of the »assignment list«.
Set the following parameters for each of the binary output relays:
•
Up to 7 signals from the »assignment list« (OR-connected);
•
•
Each of the assigned signals can be inverted;
•
The (collective) state of the binary output relay can be inverted (open or closed circuit current principle);
•
»Latched« active or inactive
•
»Latched = inactive« :
If the latching function is »inactive« , the alarm relay respectively the alarm contact will adopt the
state of those alarms that were assigned.
•
»Latched = active«
If the »latching function« is »active« , the state of the alarm relay respectively alarm contact that
was set by the alarms will be stored.
The alarm relay can only be acknowledged after reset of those signals that had
initiated setting of the relay and after expiry of the minimum retention time.
