Procedure
Open the Front Door and cheat the Interlock.
Run
DC330
[009-054] (Notes) (1ST BTR RETRACT MOTOR
CONTACT).
Did the 1ST BTR perform the CONTACT operation?
Y
N
Was the 1ST BTR RETRACT MOTOR going to operate?
Y
N
Is +24 VDC measured between the I/F PWB J533-
A16 (+) and GND (-)?
Y
N
Check the +24 VDC INTLK circuit to the I/F
PWB J533-A16 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 conductivity of the following:
• Between the I/F PWB J533-A16 and 1ST BTR
RETRACT MOTOR J237-5
• Between the I/F PWB J533-A19 and 1ST BTR
RETRACT MOTOR J237-4
• Between the I/F PWB J533-A18 and 1ST BTR
RETRACT MOTOR J237-3
• Between the I/F PWB J533-A17 and 1ST BTR
RETRACT MOTOR J237-2
• Between the I/F PWB J533-A16 and 1ST BTR
RETRACT MOTOR J237-1
If no problems are found, replace the 1ST BTR
RETRACT MOTOR.(PL5.4)
If the problem persists, replace the MCU PWB.
(PL13.1)
If the problem persists, replace the I/F PWB. (PL9.1)
Remove the mechanical load on the Contact/Retract
mechanism of the 1ST BTR.
Run
DC330
[004-014] (1ST BTR RETRACT SENSOR
POWER).
Run
DC330
[009-203] (1ST BTR RETRACT SENSOR).
And then, run
DC330
[009-055] (Notes) (1ST BTR RETRACT
MOTOR RETRACT) and
DC330
[009-054] (Notes) (1ST BTR
RETRACT MOTOR CONTACT) alternatively.
Is the level of the 1ST BTR RETRACT SENSOR switched
between H and L?
Y
N
Check the 1ST BTR RETRACT SENSOR using
Permeable Sensor Failure FIP.
Replace the MCU PWB. (PL13.1)
009-349 1ST BTR RETRACT FAILURE
Description
The 1ST BTR RETRACT SENSOR does not
detect L within the specified time after the 1ST BTR
RETRACT MOTOR was turned On (RETRACT operation has
begun).

Check conductivity of the following:
• Between the I/F PWB J533-A20 and 1ST BTR
RETRACT MOTOR J237-5
• Between the I/F PWB J533-A19 and 1ST BTR
RETRACT MOTOR J237-4

DC330
[009-055] (Notes) (1ST BTR RETRACT
MOTOR RETRACT) and
DC330
[009-054] (Notes) (1ST BTR
RETRACT MOTOR CONTACT) alternatively.
Is the level of the 1ST BTR RETRACT SENSOR switched
between H and L?
Y
N
Check the 1ST BTR RETRACT SENSOR using
Permeable Sensor Failure FIP.
Replace the MCU PWB. (PL13.1)
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.
