6.4.2.5 Marshalling of the command relays -
block 64
The bay unit contains 5 command relays, which are
designated by COMMAND RELAY 1 to 5. Several
functions can be marshalled to one command relay. In
the same way it is possible to marshall each logical
function to more than one command relay. The funcĆ
tions listed in table 6.8 can be marshalled to the comĆ
mand relays, too. The command relays are in the first
place determined for TRIP commands and transfer
trip signals. Depending on the station configuration
and the requirements they may, however, also be
used as additional alarm relays.
The pre-set functions upon delivery of the devices
are summarized in table 6.10.
