Safety Introduction Product Overview Installation Operation
Pressure Governor Operation
The Waterous pressure governor uses various inputs to control the engine speed and discharge pressure. Additional control and information is available through
configuration settings and cable selection. Operating modes are available when the interlock settings permit. Upon power-up, 3 interlock inputs are available,
Throttle Ready
,
Pump Engaged
, and
OK To Pump
. The
Throttle Ready
interlock allows the pressure governor to control the engine. The
Pump Engaged
interlock allows the pressure governor to control the fire pump. The
OK To Pump
interlock is active when 1 of 2 conditions occur. One condition is when the
Throttle Ready
and
Pump Engaged
interlocks are simultaneously active. The second condition is when the
OK To Pump
interlock is active, and the
OKTOPUMP configuration parameter is set to OKTOPUMP. High-idle mode is activated when the
High-Idle
input and
Throttle Ready
interlock are active, and
the fire pump is inactive.
Speed Mode
This mode prioritizes the engine speed.
The pressure governor manages the
throttle to keep the engine speed at the
selected set-point.
Idle Mode
This mode brings the engine speed to idle.
The pressure governor manages the
engine and brings the engine speed to the
selected idle set-point.
High-Idle Mode
This mode raises the engine speed to
resolve a low-battery condition. A low-
battery condition is indicated by a yellow or
red battery icon.
Pressure Mode
This mode prioritizes the pump-discharge
pressure. The pressure governor manages
the engine speed to keep the discharge
pressure at the selected set-point.
Use the table to determine the available modes at given interlock states.
