39 Noload protection
Noload protection
M10x protects the motor against no load
conditions. Practically, noload protection is the
same function as underload protection. The
function also uses I
Lmax
/In as the criterion.
The I
Lmax
/In is compared against the no load
alarm level. When I
Lmax
/In decreases below the
alarm level a noload alarm is issued.
The I
Lmax
/In is compared against the noload trip
level. When I
Lmax
/In remains below the trip level at
a time longer than noload trip delay, a noload trip
alarm is issued and the contactor tripped.
