ABSTRACT:
A fluid operated machine is monitored and regulated by providing a logic with a memory for storing the timings of properly operating functions, and detectors the outputs of which are used to calculate the actual operating timings of the functions. The actual operating timings are compared to the timings in the memory, and if they deviate beyond acceptable tolerances a warning signal is given. In addition to monitoring the timings, the device will also open or close control flow valves to bring the operating speeds of functions within acceptable tolerances.
