
Standby pressure is adjusted at the pump, and is the pressure created by the
pump when there is no demand

Standby pressure is displayed on the console gauge when there are no active
functions
Control Valve Specs
Pressure values are measured in the load sense line with the work port blocked,
function stalled, or cylinder at the end of stroke.
The system pressure gauge on the control console displays the pump pressure.
Pump pressure is the total of work port pressure plus standby (differential) pressure;
therefore the gauge will read higher than work port pressure by the value of the standby
pressure.
The inlet relief (on the control valve) is a secondary protection in the case of
pump relief valve failure. To set this pressure, the pump pressure must be temporarily
adjusted higher than specification. Once the inlet relief is adjusted, the pump relief valve
must be reset to its proper pressure. Failure to do so will cause the truck engine to
attempt to start under load, or create excess heat generation.
