Signal delay
Every output signal can be configured either to latch (until reset by a signal) or to
have a defined reset delay. A reset delay can be entered in the field "t" and can be
changed by clicking with the mouse.
Blocking output signals throughout the system
In the case of all the output signals being blocked by the self-supervision function
or a signal applied to the blocking CU or BU input "Block output relays", the
statuses of the selected output signals cannot change. This setting determines
whether a signal is really blocked or is generated anyway.
Relay output
The current signal is assigned to the output relays with checked check boxes. Other
signals of the same type (tripping command or control signal) may also be assigned
to the same relay.
Unavailable output relays (grey) already have signals of the other type assigned to
them. The remaining relays are available for other signals.
Event configuration
The configuration of an output signal event is the same as for an input signal event.
An event is generated when the output signal is set, respectively reset.
