Valve Speed - Sets System Speed
Select Valve Speed from the Valve Setup Menu
and enter.
Rotate the right multi-switch to change the valve
speed. Values are selectable from 0 to 100.
The valve speed is applied to both valves.
The factory default setting is 50.
Presetting Valve Speed - Blade in Air Method:
1. Set up the rotating laser at a typical working range. If a selectable rotation speed is available,
set it to 600 RPM or faster.
2. Mount the receiver in its normal operating position to receive the laser.
3. Select an On-grade deadband of approximately 1/2 of the jobsite tolerance. If working at
ranges that exceed 500 feet (150 m), this may be increased to compensate for the rotating
laser's beam "bounce".
4. Set the machines throttle to normal operating RPM. Ensure the machine is on flat ground.
5. Place the blade approximately 1 foot (0.3 m) above the ground.
6. Select Manual control. Raise the blade to position the receiver at the lower edge of its
vertical reception range, but still receiving the beam. Select Automatic control.
7. The blade and receiver will move towards on-grade. Note any overshooting of On-grade.
Repeat procedure for raise correction. Once again, note any overshooting of On-grade. Adjust
the Valve Speed until there is none or one small overshoot for a full receiver length correction
in either direction of both sensors.
Increasing Valve Speed corresponds to a faster, but less stable correction.
Decreasing Valve Speed corresponds to a slower, but more stable correction.
If one side seems more reactive than the other side, the RH/LH Balance may be used to
correct this.
