pressure
governor
• It monitors both the pump discharge and intake discharge pressures and
maintains a steady pump discharge pressure within system capabilities by
controlling the engine speed or holds a selected engine RPM.
• It operates in one of two modes, pressure or RPM
PRESSURE MODE
In pressure mode the governor maintains a constant pump discharge pressure. The
discharge pressure is monitored and compared to the Operator’s selected pressure
setting, the engine RPM is varied to keep the discharge pressure at the selected setting.
RPM MODE
In RPM mode the governor maintains a constant engine RPM.
FRC GOVERNORS
What is the purpose of a Governor?
Engine Control Methods:
• J1939 or ISO CAN Bus
– Most current production diesel engines
• Analog Signal (0.6 – 4.5V max)
– Used on most engines prior to CAN Bus
datalink control capability
– Used to control most engines, except
Caterpillar
• Pulse Width Modulated (PWM) Signal
– Used to control Caterpillar engines prior to
May 2008

FRC GOVERNORSPROVIDE SAFER PUMP OPERATION
• Constantly monitors discharge
pressure and make corrections
if required.
• Limits RPM increases when
conditions arise that fall outside
of normal operating parameters.
• Message display always alerts
operator to what the governor is
doing and what type of problem
it is encountering if one exists
Running Away From Water
● If pressure drops and an
increase in RPM does not bring the
pressure back up, the governor
recognizes this as a running away
from water condition.
● When this condition occurs the
governor switches to the RPM
LIMIT MODE, LOW WATER CYCLE
or NO SUPPLY WATER, alerts the
operator and controls the engine
RPM accordingly.
Running Away From Waterpressure is above 45 PSI but lower than expected at that RPM
RPM LIMIT MODE
● If the discharge pressure stays above
45 PSI, the governor behaves like a
manual throttle and the operator can
raise or lower the engine RPM.
● If the RPM is manually lowered to a
point where the pump is not running
away from water and pressure is stable,
the RPM limit mode is canceled.
● When the pressure comes back to the
selected pressure setting, the RPM limit
mode is canceled and the governor
switches to normal operation.
RPM LIMIT MODESystem Monitors Both Pressure & RPM – Calculating the Pumps Output Characteristics it Limits RPM if Pressure is Not Sufficient
Running Away From Waterpressure is between 15 and 45 PSI
LOW WATER CYCLEEngine Limitedto 1100 RPM
LOW WATER CYCLE
● If the discharge pressure is between
15 and 45 PSI, the engine is set at 1100
RPM.
● If the pressure does not rise above 45
PSI in 7 seconds, the governor sets the
engine RPM at idle.
● The governor repeats the low water
cycle as long as the discharge pressure
is between 15 and 45 PSI.
● When the pressure rises above 45
PSI the governor resumes normal
operation.
Running Away From Waterpressure is lower than 15 PSI
NO SUPPLY WATER
● If the discharge pressure is below 15
PSI, the engine RPM is set at idle and
the message display flashes NO
WATER.
● If, within 3 minutes, the discharge
pressure rises above 15 PSI the
governor enters the low water cycle.
● If the discharge pressure does not
rise above 15 PSI within 3 minutes, the
governor switches to idle mode and
cancels the pressure setting.
