TE-BBR Instruction and Operation Manual
Check the Control Unit
The default settings for front panel indicators are LOCAL and ZERO. Check for these initial settings,
which should be maintained or restored prior to activating the air bearing compressed gas supply.
When power is turned ON, the red indicator LEDs for the small push-button switches on the left
panel should be on.
Note: If either switch has the green LED illuminated when power is initially
applied, there may be a problem.
Toggle the upper LOCAL/REMOTE switch on the front panel to the REMOTE (green) mode, and then
back to LOCAL (red) mode. Do the same for the ZERO/LOAD switch located directly below the
LOCAL/ REMOTE switch. An audible click of a solenoid valve should be noticed each time this switch
is pressed.
The ZERO/LOAD switch only functions when the LOCAL/REMOTE switch is in the LOCAL mode.
Control Unit Operation Checklist
1. Make sure that there are no beams on the supports and that the front panel indicators are set to
the LOCAL and ZERO modes.
2. Turn on the compressor or the valve on the compressed gas supply.
3. Using the dials on the Control Unit front panel, adjust the LINE pressure to 40 psi, and the
BEARING pressure to 25 psi. Turning the dials clockwise increases the pressure; counter-clockwise
reduces the pressure. Make certain that the LINE (supply) pressure is always set higher than the
bearing pressure to ensure adequate regulation from the bearing pressure regulator.
4. Place the LOAD switch in the ZERO mode. Adjust the ZERO pressure regulator to obtain a free-
floating condition for the shaft. Turn the dial counter-clockwise to lower the shaft, clockwise to
raise the shaft.
5. Return the ZERO/LOAD switch to LOAD.
6. Turn the LOAD pressure regulator until the shaft is again in free-float condition.
Note: Because each unit may differ in bearing characteristics, there is a sticker
attached to the gauge with the pressure settings.
