Blower Speed Selector Switch(es) - Allow user to manually select between two
speeds (Low & High) for each blower. HIGH speed (factory default) is recom-
mended for high performance (10K RPM and higher) drives.
NOTE: In the event a blower fails, always set the speed of the remaining blower
to HIGH.
Status LED(s) -
Green = Steady glow indicates normal power supply/blower operation.
OFF = No glow indicates a fault in either the power supply or blower
(or both). Refer to the Indicator and Control Panel LEDs on the
front of the DS570 for further information.
