Test K1 according to the following method:
50Hz is selected if dial K1 to the right
60Hz is selected if dial K1 to the lef
cut off the wiring clamp when use the fan speed adjusting board
Connect the two port
Dial P1 to realize fan speed adjusting
Fan speed adjusting board test method
Connect the test device with fan speed adjusting
board, dial power switch ON, then revolve P1 slowly to
place 1, place 2, place 3… until place 8, the indicate
lamp of port F(voltage output contolled by fan motor) will
change from dark to light, revolve P1 slowly from place 8
to place 1, the indicate lamp of port F will change from
light to dark.
Note: the voltage in each place is tested in the condition
of power voltage is 220V and frequence is 50Hz. When power characteristics (voltage, frequence)
change and load characteristic is different, the port F voltage output will change.
