Caution:
A function’s tripping command will normally only generate a
general tripping alarm, if it is assigned to the tripping logic
(matrix) and configured to be recorded as an event (ER).
The distance function is an exception, because it always
sets the general tripping alarm.
Tripping relays
Tripping relays can be used for signalling purposes. From Ver-
sion V4.2 signals can be assigned to tripping relays to which a
signal (‘u’ indication in the signalling channel selection window)
or a tripping logic (signals and trips OR logic) has already been
assigned. The procedure for assigning tripping relays is the
same as for signalling relays above.
The plug-in unit and channel numbers for the selected tripping
relay (e.g. C201) are indicated in the parameter value column of
the “Edit function parameters” window.
Cxyy: x = plug-in unit number (1...4)
yy = channel number (1...2).
SCS signals
Before a signal can be assigned to the SCS, the respective
group (1 to 24) must be selected in the “Select SCS group” win-
dow. The SCS signal groups 1c…24c are intended for transmit-
ting short signals via the interbay bus(signal capturing). The
“Signals to SCS” selection window then appears.
