Detection Timing
If both the Upper Home Position Sensor and the Lower
Home Position Sensor are HIGH during an initial opera-
tion:
• If the Lower Home Position Sensor (PC33) does not
go LOW at a time 2.5 sec. after the Bin Switching
Motor (M1) has started turning forward, the Bin
Switching Motor is kept deenergized for a given
period of time and then energized again to turn back-
ward. The Upper Home Position Sensor (PC32) does
not go LOW after the motor has started turning back-
ward.
• When the Lower Home Position Sensor (PC33) goes
LOW, the Bin Switching Motor (M1) starts turning
backward. The Upper Home Position Sensor (PC32)
does not go LOW at a time 2.5 sec. after the motor
has started turning backward.
• When the Lower Home Position Sensor (PC33) goes
LOW, the Bin Switching Motor (M1) starts turning
backward. The Lower Home Position Sensor (PC33)
does not go HIGH at a time 1 sec. after the motor has
started turning backward.
• The Home Sensor (S31) is LOW at a timing immedi-
ately before the Shift Motor (M1) starts turning back-
ward.
• The Home Sensor (S31) is LOW after the lapse of a
given period of time after the Shift Motor (M1) has
started turning backward.
• The measurement taken by the ATDC Sensor (UN1)
at a time 2.5 sec. after the Main Motor (M1) has
started turning is less than 3 % (greater than 4.98 V).
• The measurement taken by the ATDC Sensor (UN1)
at a time 2.5 sec. after the Main Motor (M1) has
started turning is 19 % or more (1.41 V or less).
• The adjustment of the ATDC control voltage is not
completed within 1 sec. after sampling has started of
the ATDC Sensor (UN1) as part of an operation of
ATDC Sensor Automatic Adjustment.
• The ATDC Sensor control voltage falls outside the
range of 5.39 V to 8.15 V during an operation of ATDC
Sensor Automatic Adjustment.
Master Board (PWB-A) to Control Board (PWB-C) con-
nection failure
• There is no acknowledge signal transmitted from the
Master Board (PWB-A) to Control Board (PWB-C) for
1.5 sec. or more.
• An error command signal is transmitted from the Con-
trol Board (PWB-C) to Master Board (PWB-A).
• An error status signal is transmitted from the Master
Board (PWB-A) to Control Board (PWB-C).
