3. Set the lowering speed while the car is in motion during an Up or Down run.
a. Turn the Lowering Speed adjustment in one-half turn increments. See Figure 9 on
page 2-27.
b. After each adjustment, leave the flat end of the screw pointed 45 degrees to the
tank return line.
c. Run the car to confirm the correct Down High Speed as displayed on the con-
troller’s UIT home screen.
If no speed change occurs with one full turn on the lowering speed adjuster, DO
NOT CONTINUE TO TURN IT OUT. Ensure the DN Start adjustment is turned out at
least one turn more than the DN Stop adjustment; should the issue remain, refer
to the troubleshooting section of the valve component manual.
Down Leveling Speed and Down Stop
The Down Leveling Speed and the Down Stop adjustments must be performed together
since Down Stop affects Down Leveling Speed. Down Leveling Speed, however, does not
affect Down Stop.
1. Place the controller on Inspection Operation.
2. Adjust Down Stop for a positive stop. See Figure 9 on page 2-27.
To avoid damage to the piston face and seat, never turn the Down Lowering and
Leveling Speed adjustment unless the car is in motion or resting on the buffers.
3. Adjust the Down Leveling Speed to 10–12 FPM.
4. Tighten the locknut on the Down Leveling Speed adjustment.
5. Re-check the Down Leveling Speed.
