Bit Comment
17 Remote parameterization protection acti-
vated on communication module with
role A. Remote parameterization protec-
tion is a DIP switch that prevents parame-
ters from being changed via
communication.
18 Remote switching protection (RSP) acti-
vated on communication module with
role A. Remote switching protection (RSP)
is a terminal that must be bridged in order
to deactivate remote switching protection
(RSP).
19 If CubicleBUS² is not active, this indicates
an internal communication error and may
be the reason why internal data are not
available.
All rotary switches of the ETU600 are in
the e.SET position, all parameters can be
set via the communication connection.
21 When the VTM module is active, voltage
and energy metering values are available.
Depending on the functions of the
ETU600, other metering values or extend-
ed protective functions are also available.
22 Warning is present.
Active warning can be determined in
register 0x61DC "ETU warnings". For more
information, see section Status of warn-
ings (Page 24).
23 The Bluetooth interface deactivates itself
automatically after a set time if it is not
used.
26 Maintenance is required when compo-
nents of the circuit breaker have reached
the end of their service life and need to be
replaced.
