Trip conditions
LS_Status[1]
Bit 0 Trip I
i
: short-circuit
LS_Status[2] Bit 1 Trip I
2
t (when I
2
t option selected):
Overload variable short-time delay
Trip I
mv
(when I
2
t option not
selected):
Overload constant short-time
delayed
LS_Status[3]
Bit 2 Trip I
r
: Overload variable long-time
delayed
LS_Status[4] Bit 3 Trip I
dn
: Fault current, constant
short-time delayed
LS_Status[5]
Bit 4 Trip Select: time limit with H-
selectivity exceeded (not yet
supported)
LS_Status[6] Bit 5 Trip Com: trip has been initiated via
PROFIBUS-DP
LS_Status[7] Bit 6 Trip Temp: trip due to device
overtemperature (NZM)
LS_Status[8]
Bit 7 Not used
Octet 2
1)
Alarm conditions
LS_Status[9] Bit 0 Load rejection prewarning
LS_Status[10]
Bit 1 Overload range 1
LS_Status[11] Bit 2 Overload range 2
LS_Status[12] Bit 3 Motor protection (only significant
with -ME types, otherwise constant
“0”): the circuit-breaker has
detected an overload case and
demands that the DMI switch off the
motor. If the overload continues, the
circuit-breaker will trip.
