Problem Possible Cause Remedy
Loss of capacity. Leak in the system. ● Find the leaks and stop
them.
Activated safety valve. ● Check differential pressure
and see causes marked with
*.
Possibly set the safety
valve’s opening pressure.
Dirty inlet filter or blocked
pipes.
● Clean and possibly replace
filters and pipes.
Loose belts. ● Replace belts.
Too high differential pres-
sure*.
● See symptoms and causes
marked with *.
Continuously activated safety

cally wired.
● Check and reconnect.
Overloading. ● Look for causes of increased
differential pressure in the
system and repair.
Wrong power supply. ● The power supply must be
consistent with data on mo-
