System Overview
The Waterous pressure governor uses various apparatus 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 interlock settings permit.
Speed Mode
This mode prioritizes the engine speed.
The pressure governor uses SEA J1939
protocol to control the throttle and
maintain the engine speed set-point.
Idle Mode
This mode brings the engine speed to
idle. The pressure governor uses SEA
J1939 protocol to control the throttle
and bring engine speed to the idle
set-point.
Pressure Mode
This mode prioritizes the pump-discharge
pressure. The pressure governor manages
the engine speed to maintain the pressure
set-point.

Installation Overview
This equipment is intended to be installed by a person or persons with the basic
knowledge of installing similar equipment. Contact Waterous with questions
about installing the equipment. The installation may require the following tasks
and abilities:
• Locating, drilling, and cutting
features into the apparatus.
• Connecting electronic devices.
• Configuring and calibrating the
system.
• Final testing.
• Do not install the equipment if you are not familiar with the tools and skills
needed to safely perform required procedures—proper installation is the
responsibility of the purchaser.
Determining Cable and Wire Routing
Use the Wiring Best Practices document, available at www.waterousco.com, as
a guide to select and route wiring for your application.
Preparing for the Installation
Read and understand all the installation instructions before installing the
equipment. Prepare a suitable, well-lit area, and gather all the necessary tools
before you begin the installation.
NOTICE
Before Operation
• Read and understand all
the instructions provided.
• Check all fluid levels
and replenish if necessary.
• Remove all shipping plugs
and install the operation
plugs or caps.
