Chapter 17 Troubleshooting
17-2
17.1 Solutions When Trouble Occurs
If trouble occurs in the DRYPRO 832 main unit, use the solutions shown in the table below.
17.1.1 The DRYPRO 832 main unit will not start
Phenomenon
Parts to check
Cause
Solution
When the power
source breaker is
turned ON, it returns
to OFF
The power source
breaker protection
has activated
Short circuit in the AC line
Disconnect the power cable, then check
the conductance between TP1-TP2, TP1-
TP5, TP2-TP5.
If there is no conductance, replace the
power source breaker.
If there is conductance, replace the noise
filter, multiple power supply, power Assy,
noise filter Assy, and CB1 Assy.
Even if the main
power supply is on
and the operation
switch is pressed, the
LCD on the operation
panel is not displayed
Bad connection
A power cable (on the equipment
or wall socket) is not plugged in
Visually inspect how well the main power
supply side and equipment side cables are
inserted.
Broken wire in the
power cable
The power cable has a broken
wire
Remove the power cable from the
equipment, and check the power cable
conductance with a tester.
Replace the power cable if a broken wire
is found.
Power is not being
supplied from the
main power supply
or UPS
There is a fault on the main
power supply side or UPS
Check the output voltage of the main
power supply or UPS with a tester.
If there is no voltage output from the
main power supply or UPS, request
repairs from the facility owner.
STBY 5V is not
being output
Power fault or MEC fault
Measure the multi power ACN5 5 pins as
+ and 6 pins as - with a tester, and check
that 5V is being output.
If 5V is not output, replace the multi
power and MEC power Assy. If this does
not resolve the problem, replace the MEC
board.
Defective operation
of the operation
switch
Operation switch fault, or broken
wire in the cable
Check the connection of the densitometer
relay Assy, and if there are no problems,
remove MCN13 from the MEC board,
and check the conductance between the
MCN13 No.1 pin-No.2 pin while the
operation switch is pressed down.
If there is no conductance, replace the
operation switch board and densitometer
relay Assy.
Defective operation
of LCD board
Faulty LCD board, broken wire
in the cable, disconnected
connector, short circuit
Check the connection of the LCD relay
Assy, and if there are no problems,
replace the LCD board and LCD relay
Assy.
