The  pressure  signal  shall  come  from  a  pump  mounted  pressure  transducer  allowing direct  reading  of  pressure  without  requiring  water  flow through  the  transducer  or  any part of the control system.

 

An  interlock  shall  be  incorporated  into  the  governor  that  shall  allow  the  system  to become operational only when the parking brake is set and the transmission is in drive with the midship pump engaged.

 

The governor controls shall be located at the pump operator's panel and consist of a series of indicator lights denoting system mode selection.  When the operator chooses either the "pressure control" mode or the "throttle control" mode an amber light shall come on indicating the system selected.  A momentary switch shall be used to provide an infinite setting for increasing or decreasing water pressure or engine speed.  The operator's  panel  shall  also  incorporate  a  system shutdown  push  button,  which  shall return the engine to idle.
