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.
Configuring output relay events
An event is generated when an output relay picks up or resets, that is this type of event takes any reset
delay that has been set or blocking by another signal into account. As in the case of the binary input
signals in
1. Select an output relay in the overview dialog box first by clicking on its label above the signal list
(its column is then highlighted).
2. Click CR event config to open the event configuration dialog box.
