•
Button Hold - The user may choose a one second (default), two second, or five
second button hold duration upon an event that requires a button hold.
•
Preset Pressure - The user may set a preset pressure ranging from 0 to 300 psi
(0 to 2,069 kPa).
A preset pressure of 150 psi (1,034 kPa) is default.
The user must
confirm a change in the preset pressure if changed.
•
Preset Output - The user may set a preset output to the pump displacement
solenoid ranging from 0% to 60%.
