Slope Sensor Symptom 2
“Cross Slope drives cylinder in the wrong direction.”
Probable Cause
Slope sensor installed incorrectly.
1. Verify the slope sensor is positioned correctly on the
transverse beam. “Slope Forward” Decal must be in
direction of travel.

hydraulically connected to the valve. Raised jog switch

should make the cylinder go down. Refer to the paver
manufacturers manual.

“Slope lights flash between raise and lower and will not stay
On-Grade.”
Probable Cause
Incorrect Performance Setting adjustments or a loose
transverse beam.
1. Check Valve Offset for proper operation. Refer to
“Setting Valve Offsets” section in this manual.
2. Check gain setting. Factory setting is 25.
3. Slope deadband set too low. Increase Slope Deadband.
Factory Setting is .075%.
4. Check for excess vibration in the Transverse Beam due
to poor connection at Tow Arm.
