Valve Adjustment
(continued)
2. Run the empty car on Automatic Operation up into the master floor. Note where the
car sill is in relation to the master floor hatch sill.
3. Run the empty car on Automatic Operation down into the master floor. Note where the
car sill is in relation to the master floor hatch sill.
4. Achieve a valve stop that results in the same final car location in both travel directions.
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.
How to change the leveling speeds for the appropriate travel direction.
• Increase the leveling speed - To increase car momentum and put the car further in
its travel direction upon the stop.
• Decrease the leveling speed - To decrease the car momentum and shorten the final
resting place of the car in its travel direction.
DO NOT exceed 14 FPM maximum for empty car leveling speeds.
The UP and DOWN stop adjustments need to be firm so that the stop can be felt slightly (a
soft but noticeable bump at the stop), as this prevents fluid temperature-based variations
in performance and allows the control system to achieve increased car level positioning
control.
Relevel Check - All Jobs
1. Place the empty car on Automatic Operation at the master floor or at the top floor of a
two-stop job.
2. Force an UP relevel, and verify that the control system and the valve place the car at
floor level.
a. On the I-2/I-3 Valve, slowly turn the Manual Lowering Valve (t-handle) counter-
clockwise (ccw) to open, allow the car to lower slightly, then quickly turn the valve
clockwise (cw) to close.
b. Ensure that the car went low enough: >

" with P19 & P22 at default value.
• If the car did not go low enough: Troubleshoot the Manual Lowering Valve to
identify the problem, and repeat the relevel check until correct.
• If the car went low enough: The motor and valve should energize and
place the car back at floor level.
