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.
