Does the Lamp Carriage scan?
Y
N
Are voltages from P/J 405-7,P/J 405-8 to COM +24VDC?
Y
N
Check +24VDC INTLK circuit.
Power off and disconnect P/J 605.
Are J605-1 to -3,J605-1 to-4, J605-2 to -5,J605-2 to -6
resistance values approx. 6.3
Ω
each?
Y
N
Replace the Lamp Carriage Motor.
Replace the Main PWB.
Enter [6-4] and press the
start
button.
Does the Lamp Carriage return?
Y N
Replace the Main PWB.
Using the Permeable Sensor F.I.P., General F.I.P. and the wiring
diagram, perform the diagnosis of Optical Regi Sensor. If no problem
exists, replace the Main PWB.
U3-1
LENS POSITION FAIL
Ref. BSD: 3
Preparation
: Ensure that the following connectors are securely
connected.
•
P/J405 of Main PWB
•
Relay Connector P/J604 of Lens Motor
•
Remedy the mechanical jam
•
Check the Lens Cable for disengagement, binding,
load, etc.
Procedure
Power on.
Does the Lens Assy move?(Does it perform its initial operation?)
Y
N
Are voltages from P/J 405-1,P/J 405-2 to COM +24VDC?
Y
N
Check +24VDC circuit
Power off and disconnect P/J604.Are J604-1 to - 3,J604-1 to
-5,J604-2 to -4,J604-2 to -6 resistance values approx. 100
Ω
each?
Y
N
Check P405-3,4,5,6 of Main PWB and P604-3,4,5,6 of
Lens Motor for an open circuit or a short circuit to
ground.
If the harness is good, replace the lens Motor.
Replace the main PWB.
Using the Permeable Sensor F.I.P., General F.I.P. and the wiring
diagram, perform the diagnosis of Lens Sensor. If no problem exists,
replace the Main PWB.
