Problem
The valve will not drive hydraulic cylinder far enough to get
sensor On-Grade
Causes Solutions
Valve offsets in
Control Box are set too
low
Raise the Valve Offset Value until the
sensor is driven to grade. See “Valve
Offset” on page 2-22 for more
information.
For Servo and Solenoid valves raise the
value by 2 to 5 numbers, then check
hydraulic performance
For Proportional valves raise the value by
10 to 15 numbers, then check hydraulic
performance
