Fan Tray
The fan tray unit contains 8-12V fans which pull air from the front of the unit through a series
of air vents. A curved frame, housing the front panel display unit, attaches to the front of the
fan tray unit and should be considered an integral part of the fan tray unit. This curved frame
should not be removed at any time.
NOTE:
If the fan tray unit is removed for more than two minutes, the encoder may shut down.
