Continuity Test for Shunt CoilISeries
Coil
Continuity of the shunt coil
is
checked by
taking
a
reading between its S-terminal and
the body of the magnetic switch.
If
there
is
no continuity, then there is
a
break in
the shunt coil winding.
Continuity of the series coil
is
checked
between the S-terminal and the M-terminal.
If
there is no continuity, there is a
break
in the series coil winding.
