Status Indicator RAPs
8-306 Drawer Interlock Open RAP
The Drawer Interlock is detected open.
Initial Actions
Refer to BSD 1.4 and BSD 8.10 for the following procedure.
Procedure
Enter dC330 008-306 Drawer Interlock Switch. Press Start. Open, then close, the Drawer.
The display changes from H when the Drawer is open to L when the Drawer is closed.
YN
Connect the meter from P
/J4
19B-18 on the IOT Drive PWB to machine frame. Open,
then close, the Drawer. The voltage at P/J419B-18 go
es from +5 VDC when the
Drawer is open to less than +1.0 VDC when the Drawer is closed.
YN
Connect the meter from P/
J11A-
3 on the AC Driver PWB to machine frame. Open,
then close, the Drawer. The voltage at P/J11A-3 g
oes from +5 VDC when the
Drawer is open to less than +1.0 VDC when the Drawer is closed.
YN
Connect the meter from P/
J14-8
on the AC Driver PWB to machine frame.
Open, then close, the Drawer. The voltage at P/J14
-8 goes from less than
1.0 VDC when the Drawer is open to +5.0 VDC when the Drawer is closed.
YN
There is + 5 VDC from P/
J19-4 on
the AC Drive PWB to machine
frame.
YN
Replace the AC Driver PWB (PL 9.3).
Go to F
lag 7 on BSD 1.
4 and check the harness for an open circuit. If the
harness is good, replace the Drawer Interlock Switch (PL 2.18).
Replace the AC Driver PWB (PL 9.3).
Go to Flag 6 on
BSD 1.4 and check the harness for an open circuit.
Replace the IOT Drive PWB (PL 9.2).
I
f the fault code is present and can not be cleared, replace the IOT Drive PWB (PL 9.
2). If the
fault code is not present and is occurring intermittently, go to Flag 6 on BSD 1.4 and check the
harness for an intermittent open circuit. If the harness is OK, go to Flag 7 on BSD 1.4 and
check the wire for an intermittent open or short circuit. If the harness is good, replace the
Drawer Interlock Switch (PL 2.18). If the problem continues, replace the AC Driver PWB (PL
9.3). If the problem still continues, replace the IOT Drive PWB (PL 9.2).
Main Motor 2 RAP
Main Motor 2 is inoperative.
Initial Actions
Refer to BSD 8.9 for the following procedure.
Procedure
Enter dC330 008-043 Main Motor 2. Press Start and Stop several times. Main Motor 2 ener-
gizes and deenergizes.
YN
Press St
op. +24 V
DC is measured between P/J414B-3, 4, 5, 6 on the IOT Drive PWB
and machine frame.
YN
+24 VDC is measured between P/
J414B-1 on
the IOT Drive PWB and machine
frame.
YN
Replace the IOT Drive PWB (PL
9.
2).
Go to Flag 1 and Fl
ag 2 on BSD 8.9 and check the harness and connectors. If the
harness and connectors are OK, replace Main Motor 2 (PL 1.5).
Press Start. Th
e voltage at P/J414B-3, 4, 5, 6 on the IOT Drive PWB goes to approx-
imately +23 VDC.
YN
Replace the IOT Drive PWB (PL
9.
2).
Replace Main Motor 2 Motor (PL 1.
5).
If the problem is occurring intermittently, go to Flag 1
and Flag 2 on BSD 8.9 and check the har-
ness for an intermittent open circuit. If the harness is good, replace the Main Motor 2 (PL 1.5).
If
the problem continues, replace Main Motor 2 (PL 1.5). If the problem still continues, replace
the IOT Drive PWB (PL 9.2).
