TP5 DC24 V voltage measurement
• Order distinguish LED PCB, sensor
power supply, analog power supply
(DC12 V), colorimeter power supply
(DC12-1 V) and thermosensor analog
power supply (DC12 V)
• Connection failure between processor power
supply 1 and processor control PCB
• Failure in processor power supply 1 and
processor control PCB
• It shorted out between the processor control
PCB and order distinguish LED PCB
• The order distinguish LED
PCB does not emit light.
• The colorimeter does not
work.
• The order distinguish LED
PCB does not emit light.
• The temperatures of the
processing solution
temperature sensor and
dryer tthermosensor cannot
be adjusted.
TP6 DC5 V voltage measurement
• Power supply for digital circuits such
as FPGA, memory and CPU
• Connection failure between processor power
supply 1 and processor control PCB
• Failure in processor power supply 1 and
processor control PCB
• It shorted out between the processor control
PCB and each sensor.
•
☞No. 06901 ARCNET
