AirSep Corp. — FreeStyle Service Manual 5-19
5.11 Hour Meter Functionality
General
FreeStyle’s hour meter includes two monitoring channels: a historical channel
that cannot be reset, and a maintenance channel ( See Figure A-1). An onboard,
momentary-action pushbutton can be used to toggle the display between the two
channels. While displaying the maintenance channel, the switch can be used to
reset the accumulated maintenance hours to zero. Reset the hour meter at each
5,000-hour interval. The historical channel is generally used to monitor total
operating hours over the life of the FreeStyle unit, while maintenance channel
provides the hours logged between service intervals. When the preset maintenance
interval is reached, an external yellow alarm/service indicator at or displays on the
keypad. This light remains on until the maintenance timer is reset. Note that the
historical channel cannot be reset.
5.11.1 Icons
Two LCD icons are used to indicate each mode. In historical mode, an
“h” is displayed to indicate hours. While enabled, the “h” will illuminate
intermittently. In maintenance mode, both a “wrench” symbol and an “h”
are displayed.
5.11.2 Power
When the FreeStyle is connected to AC or DC power, the historical hour
meter reading is displayed along with the “h” icon.
When the FreeStyle is connected to AC or DC power supply, the hour count is
displayed, but the time does not accumulate. When the FreeStyle compressor
is started when the unit is turned on, the historical hour meter will function.
The “h” icon will flash to indicate that time is being accumulated.
5.11.3 Service LED
When the FreeStyle unit has reached the predetermined interval of 5,000
hours, the alarm/service indicator in the upper left hand corner of the
keypad will display yellow to indicate that the expected check
performance period has been reached. This light remains on until reset in
maintenance mode.
