Operation
!
CAUTION
If the rotor makes an unusual noise, turn the
timer to zero. When the rotor stops, open the
chamber door and remove the rotor. Check to
make sure the rotor is loaded correctly. Correct
the problem before restarting the run (see
Table 4-1).
ENDING THE RUN
1. When the timer reaches or is turned to zero, the rotor will coast for
about 2 minutes. After the 2-minute delay period, the run light
goes out and the brake pin engages the rotor. The rotor will stop
about 1 to 3 minutes later, depending on the rotor.
➠
NOTE
If the coasting time is too short—45 seconds or
less—check the time-delay relay setting and/or
adjust the flow of levitation air as described in
Section 5.
2. After the rotor has stopped , turn the pressure regulator knob to
the left (counterclockwise) until the PRESSURE gauge reading
is zero.
3. Open the chamber door. Refer to the applicable rotor manual for
instructions on unloading and cleaning the rotor.
➠
NOTE
Do not tighten the pressure regulator knob
between runs.
