4.2.4 OPERATION OF AUTOMATIC
FEEDING DEPTH CONTROL LAMP
The automatic feeding depth control lamp is automatically
turned on by the automatic feeding depth selection switch.
This lamp is turned off if the manual switch is operated. If
an error 1 is generated during self-diagnosis, it blinks.
4.2.5 OUTPUT STOP OF SHALLOW AND
DEEP FEEDING MOTORS
When the feeding chain reaches the shallowest or deepest
feeding position, the limit switch turns OFF (normally ON)
and stops the relay which cuts power to the feeding depth
control relay. Then, power will not be supplied to the feed-
ing depth control motor.
4.2.6 MOTOR PROTECTION
If the feeding depth control relay's output in the threshing
controller is sent out 60 times consecutively to one direc-
tion, outputting to the direction is restricted. This restriction
is cancelled when the output is sent to the opposite direc-
tion or when the grain sensor S1 is ON and the S2 is OFF.
