The Serial Atomizer Module maintains complete
control of the rotator speed. Normal operating
conditions are indicated by reading "00" or the
requested speed on the front panel display readout.
The DRIVE LED will be lit during all speed re-
quests except "00". The BRAKE LED will be lit
only during the transition from a higher speed to a
lower speed. It is normal for BRAKE and DRIVE
LED's to be on at the same time during speed
changes.
If during normal operation speed feedback is lost
or speed control is not maintained within 10 krpm,
the Serial Atomizer Module will enter the automatic
shutdown mode.

When the Serial Atomizer Module automatically
shuts down because of the abnormal conditions
(See "Automatic Shutdown" in the "Operation"
section) it is extremely helpful to know what the
status is when troubleshooting. This status can
be displayed directly on the Atomizer Module
display which is normally used for displaying
turbine speed by setting SW2-6 to ON and SW2-
5 to OFF. These status codes are explained in
Figure 5. Note that the module can display a
status code, such as loss of feedback, Code 04,
but not be in an automatic shutdown condition, say
if the speed was set to zero. If the F.O. feedback
was interrupted while the bell was running, this
would cause an automatic shutdown and display
Code 44. Anytime the module shuts down
automatically, and the display is in this mode, it will
add 40 to whatever is being displayed.
