5. Reset auto stopper (protective switch)
Function of auto stopper
A running pump with a broken
diaphragm may cause a major break
down and excessive repair cost. To
prevent this from occurring, EL-
series pumps are equipped with a
protective switch.
If the diaphragm is broken, the
magnet reciprocates with abnormal
amplitude and the projection of the
magnet hits the slider of the auto
stopper. The contact is interrupted
and power is cut off.
