The circuit selection wiper on Electrical Reset Steppers can be reset to zero or the home position
from any desired position by energization of the reset magnet. One of the most versatile and widely
used steppers in the Guardian line, the ME offers smooth and reliable performance - proven in thou-
sands of applications. The interlock arraingment between the reset and step magnets allows the
MER to perform some of the functions of an interlock relay.
