0x0042
Overtemperature
(0 -> 1): alarm - overtemperature is
active
(1 -> 0): alarm - overtemperature is
not active
The relay will respond if the internal circuit breaker
temperature is too high. The relay will respond at 5 °C
below the threshold of the overtemperature release.
The relay will drop out again with a hysteresis of 5 °C.
0x0043
Ground-fault pre-alarm
Default setting for relay 2
– for breakers with
ground-fault protection
(0 -> 1): alarm - ground fault is active
(1 -> 0): alarm - ground fault is not
active
The relay will respond if the adjustable threshold value
of between 50 % and 100 % of I
g
is exceeded.
If the setting “ground-fault alarm” has been selected,
the threshold will be set to 100 % of I
g
.
The relay will drop out again with a hysteresis of 5 %.
Default settings: 75 %
0x0044
Thermal memory
(trip is imminent)
(0 -> 1): alarm - thermal memory full
(75 %)
(1 -> 0): alarm - thermal memory
normal
The relay will respond if the thermal memory of the
breaker is 75 % full.
The relay will drop out again with a hysteresis of 5 %.
0x0045
Watchdog
(0 -> 1): alarm - watchdog is active
(1 -> 0): alarm - watchdog is not
active
The relay will respond if an external power supply is
available and the trip unit is functioning normally.
The relay will drop out if a fault has occurred that can be
detected by the trip unit’s internal diagnostics. If the
external power supply is interrupted, the relay will also
drop out.
0x0047
Internal error
(0 -> 1): alarm - internal error has
been detected
(1 -> 0): alarm - internal error has
been reset
The relay will respond if a fault has occurred that can be
detected by the trip unit’s internal diagnostics. The relay
will drop out, either if the device has been reset, or a
reset command has been sent via the communication
interface, provided that the fault is no longer present.
0x0048
Settings error
(0 -> 1): alarm - settings error has
been detected
(1 -> 0): alarm - settings error has
been reset
The relay will respond, if a settings error has been
detected.
0x0049
Low residual life
(0 -> 1): alarm - residual life is less
than x % (adjustable threshold)
The relay will respond if an adjustable threshold value of
between 0 % and 50 % of residual life is exceeded
(default value: 25 %)
0x004A
Communication error
(0 -> 1): alarm - communication error
(1 -> 0): alarm - communication error
has been reset
The relay will respond, if an external communication
error has been detected. The relay will open if the device
has been reset, or a reset command has been sent via
the communication interface. If the error continues to
persist, the relay will again respond.
Note:
Detects only external communication errors. Internal
communication errors are covered by position 18.
0x004B
General alarm
(0 -> 1): alarm - general alarm
(1 -> 0): alarm - general alarm has
been reset
The relay will respond in the event of an alarm
(alarm reasons 12 to 21). The relay will drop out once the
alarm is no longer active.
0x0020
Standard auxiliary
contact (HIN)
( 0 -> 1): status: device is closed
(1 -> 0): status - device is open
The relay will respond if the circuit breaker is in the
“closed” contactor state.
The contactor states “open” and “tripped” will cause
the relay to drop out.
0x0021
Trip-indicating auxiliary
switch (HIA)
(0 -> 1): status - device has tripped
(1 -> 0): status - device has been reset
The relay will respond if the circuit breaker is in the
“tripped” contactor state. Once this is no longer the
case, the relay will drop out.
