ERROR E5 to ERROR FF frequently
occur.
• Replace the main PCB with a new one.
All solenoids of head do not operate.
• Refer to the block diagram showing cable connections and check fuse
F2 on the power supply PCB.
If it is blown, replace it with a new one. The 60v circuit is faulty if the
fuse is blown immediately after turning on the power even after
replacing the fuse.
Jump solenoid does not operate.
• Check to see if connection from the jump solenoid to connector P10 of
the head PCB is proper.
• Check the resistance value of the jump solenoid which does not operate
with the connector section. The normal resistance value is
approximately 185
Ω
.
If it is faulty, replace the solenoid with a new one. In this case, the
head PCB may also be faulty. Also replace the head PCB with a new
one if it does not operate properly even after replacing the solenoid.
• Replace the head PCB with a new one.
Pickker solenoid does not operate.
• Check to see if connection from the pickker solenoid to connector P8
of the head PCB is proper.
• Check the resistance value of the pickker solenoid which does not
operate with the connector section. The normal resistance value is
approximately 426
Ω
.
If it is faulty, replace the solenoid with a new one. In this case, the
head PCB may also be faulty. Also replace the head PCB with a new
one if it does not operate properly even after replacing the solenoid.
• Replace the head PCB with a new one.
• Enter the encoder signal test mode and manually turn the main shaft
pulley.
If it is abnormally heavy, the main shaft mechanism is faulty.
• Refer to the block diagram showing the cable connections and check
to see if connection from the main shaft motor to the main PCB is
proper. Also check the connection from connectors P14 of the main
PCB to the 14v terminal of the power transformer.
Main shaft rotation speed error oc-
curs.
• Refer to the block diagram showing the cable connections and check
to see if connection of connector P22 of the main PCB in the control
box is proper.
• Check fuse F3 on the power supply PCB.
If it is blown, replace it with a new one. If it becomes blown again,
the 24v system circuit is faulty.
Exhaust fan motor stops.
