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.
