5.5.5 Marshalling of the command relays -
block 64
The device has 2 command relays with trip duty, desi
gnated as CR 1 and CR 2. They can be marshalled in
block 64. You can reach the block from the initial state
of the device in level 1 as follows: Press the B key
(forwards), switch to the 2nd operating level with the
" key (next level), scroll with the B key until block
60 appears on the display. Switch to operating level 3
with the " key and scroll to block 64 with the B key
!: Marshalling command relay. Selection is carried
out as described in section 5.5.1. Multiple commands
are permitted, i.e. a logical indication can be transmit
ted to several command relays (see section 5.5.1).

All indications shown in table 5.3 can be marshalled
to command relays. Command functions have no ef
fect if the relevant protective function in the device is
not available, switched off or has been configured so
that it is not available or is parameterized as indication
only.
The general diagrams in appendix A show the assign
ment of the command relays on delivery. The follo
wing boxes show some examples for command
relay 1.
Table 5.6 shows all factory settings.
If several protective functions are to trip the same
circuit breaker, the relevant command relay must be
activated by the relevant command function.
