19 Diagnostics FieldLevel II diagnostics valve test
Rate fluctuates around target.
1. Check that a drive calibration has been performed.
2. Set the Rate to Manual. With the drive "locked" the drive should be running steady. If the rate
is still fluctuating check the encoder.
If drive calibration is performed, check that motor(s) have sufficient hydraulic flow.
For Rawson:
1. Check that drive is running above 100 RPM. Adjust gate height to achieve proper RPM.
2. Isolate the drive from the shaft if possible (try to minimize the load on the drive.) Make sure the
drive operates properly with little or no load.

or an active field design open by either tapping:
l Auto: To engage the system (this sets the current elevation as Target Height = 0.0) and tests its
response as height offsets are added or subtracted from the current elevation, based upon the
current coarse offset entered into the system
l Up or Down: To manually stroke the valve to 100% command in the required direction to verify
valve performance and wiring accuracy
GPS status
