The
Output Test
switch “S3” provides a relay sequence test. With power OFF, place S3 ON
and switch power to ICE. The correct lighting sequence should be none, 2, 3, 4, 1, & 4,
normal sequence every 5 seconds. (The LEDs are not in numerical order on the board. See
the diagram on the next page for the location and numbering of LEDs). S3 should remain in
the “OFF” position for normal operation.
The application switch located between relay X3 & X4 must be set to match the original
board application. Place this switch in the ALP position if there is no white wire supplied to
the K1 connector. If there is a white wire, place the switch in the C position. If this switch is
placed in the wrong position either the compressor contactor will remain energized with the
control switch OFF or the unit will not start.
The dip switches should be adjusted per the adjustment chart in II.C.4., “Controls and
Adjustments.” Number 8 must remain in the OFF position.
