009-342 2ND BTR CONTACT FAILURE
Description
The CONTACT operation cannot be performed
within the specified time after the 2ND BTR MOTOR was
turned On.
BSD on : CH9.24A CH9.31A
Procedure
Run
DC330
[009-200].
Open the LEFT COVER, and turn the 2ND BTR RETRACT
SENSOR On/Off with paper.
Is the display switched between H and L?
Y
N
Repair the 2ND BTR RETRACT SENSOR using Generic
Rermeable SEnsor Failure FIP. (PL2.9)
Close the LEFT COVER and run
DC330
[009-051] (Notes) and
DC330
[009-052] (Notes) alternatively.
Was the operating sound of the 2ND BTR RETRACT MOTOR
audible?
Y
N
Is +24 VDC measured between the I/F PWB J533-B8 (+)
and GND (-)?
Y
N
Check the +24 VDC circuit to the I/F PWB J533-B8
by referring to Chapter 4 Wiring Data.
(WN4.3.13 +24 VDC-1) (WN4.3.14 +24 VDC-2)
(WN4.3.15 +24 VDC-3) (WN4.3.16 +24 VDC-4)
Check the wire between the I/F PWB J533 and the 2ND
RETRACT MOTOR J216 for an open circuit and poor
contact.
Is the open circuit or poor contact found?
Y
N
Replace the 2ND BTR RETRACT MOTOR. (PL2.9)
Replace the MCU PWB. (PL13.1)
If the problem persists, replace the I/F PWB. (PL9.1)
Repair the open circuit or poor contact.
Check the mechanical connection between the MOTOR and the
Shaft and check the Sensor Actuator. If no problems are found,
replace the MCU PWB. (PL13.1)

009-348 1ST BTR CONTACT FAILURE
Description
The 1ST BTR RETRACT SENSOR does not
detect H within the specified time after the 1ST BTR
RETRACT MOTOR was turned On (CONTACT operation has
begun).
For the DC330 that have "Notes" in the following
FIP, check the machine status before selecting and
executing the appropriate DC330.
If the Diag with On signals is executed to the part
that is On, the communication link between the PSW
and the Main Unit may be broken.
In addition, the Diagnostics button indicated in
"Notes" is set to be executed after the Chain-Link
No. is selected.
