ABSTRACT:
A method for detecting trouble in a fluid pressure system which has a fluid pressure source including a fluid pump, a pressure tank connected to the pump, a pressure detector for detecting fluid pressure in the pressure tank, and a control device for controlling the operation of the fluid pump on the basis of an output signal from the pressure detector, comprising the steps of operating such fluid pressure systems with output fluid pressure from the fluid pressure source, detecting variation in the output signal from the pressure detector and when the output signal is less than a first predetermined value during operation of the fluid pressure system driving said fluid pump regardless of the output signal from the pressure detector, and when the variation in output signal from the pressure detector is less than a second predetermined value as a result of such driving of said fluid pump energizing a signal to indicate that the system is out of order. During operation of said system, monitoring the fluid pressure detected by said pressure detector for reliably and accurately detecting trouble in the system.
