CHECKLIST:
1. Place the rotary switch in the "E" position on the MPU board.
2. Ensure that the transfer elevator motor operates during power–on. If the motor is
operating properly, go to Step 5. Otherwise, go to Step 2.
3. Check the fuse.
a. Put the leads of the digital multimeter on either side of F4 (fuse 4) on the I/O
b. Measure the resistance, which should be 0Ω (the fuse is not blown).
If the fuse is blown, replace the I/O board.
4. Check the I/O board. Check whether the relay (RY2) and the transfer elevator
motor operate during power–on. If the relay is not operating properly, replace the
I/O board.
5. Ensure that the transfer unit is properly installed. The green lever must be in the
up position, and the pin beneath the lever must be fully in the up position.
6. Check the transfer elevator.
a. Remove the transfer elevator motor CN28 on the I/O board.
b. Remove the elevator motor box.
c. With the connector pins open, can the motor axis be rotated without making
d. With the connector pins short circuited, can the motor axis be rotated without
If the transfer elevator is not normal, replace it.
