2-310 UI Panel Fail RAP
This Fault Code indicates that the UI Panel failed.
Initial Actions
• Refer to BSD 2.1, Control Panel (UI Panel) Switches and LEDs, in the following proce-
dure:
• Observe all LEDs on the top of the Control Panel for functional operation.
• Check all push-buttons on top of the Control Panel for electrical/mechanical function.
• Check the Touch Panel at the UI for functional operation.
Procedure
PO/PO the machine. Fault Code 2-310 is still declared.
YN
Perform the following:
• Check the connectors to the Control Panel.
• Reseat connectors P
/J
482A, CN2, CN3, and CN1.
All push-buttons are electrically and mechanically operational.
YN
Replace the Control Panel (PL
9.
5).
All LEDs functioned in Initial Action.
YN
Go to F
lag 5 on BSD 2.1, and check for +5 VDC at P/
J482A-9,10 and CN1-9,10.
+5VDC is measured at P/J482A and C
N1.
YN
Perform the following:
•Go to F
lag 4
on BSD 2.1, and check the harness between P/J482A on the UI
PWB and CN1 on the Display Power Supply for a short/open circuit.
• Replace the Control Panel (PL 9.
5).
• Replace the UI PWB (PL 9.5).
Replace the UI PWB (PL 9.5).
Perform the following:
•Go to Flag
1, Flag 2, and Flag 3 on BSD 2.1, and check the harness for open/short cir-
cuits.
• Replace the UI PWB (PL 9.5).
• Replace the Touch Panel (PL 9.
5).
• Replace the Control Panel (PL 9.
5).
2-340 UI RAM Fail RAP
This Fault Code is detected at power on and indicates that the UI PWB RAM Test failed.
Initial Actions
• Refer to BSD 2.2 UI Display in this procedure:
Procedure
PO/PO the machine. Fault Code 2-340 is still declared.
YN
Perform the following:
• Inspect the connections and connectors to the UI PWB, VR PWB, the Display, and
t
he
Power Supply.
• Reseat connectors P/J
484, P/J486, CN5, CN6, and CN1.
Go to Flag 2 on BS
D 2.2, and check for +24 VDC UI Power Supply voltage at P/J486-1. +24
VDC is measured at P/J486-1 on the UI PWB.
YN
Perform the following:
•Go to F
lag 1 on
BSD 2.2, and check the wires for an open/short circuit.
• Replace the Power Supply (PL 9.5).
Perform the following:
•Go to Flag 2
on BSD 2.2, and check between P/J486-2 and INVCN1 for an open/short
circuit.
• Replace the VR PWB (PL 9.5).
• Replace the UI PWB (PL 9.5).
• Replace the Display (PL 9.
