XO 4 & XO FLEX TROUBLE SHOOTING GUIDE
Version 3.30
48
Satelec: 28KHz to 36KHz
Odontoson: 42KHz.
If no frequency variation, change
the generator.
If variation, and no vibration
verify that the scaler tip is
properly tied to handpiece.
No water.
No water on the instrument
bridge.
Check the water at the syringe. If
no water, refer to “water/air in XO
4 & XO Flex”.
Water on the instrument bridge
but not on other instruments
Check the following:
The nozzle in the "flow meter"
block is obstructed.
Clean the flow regulator properly.
Read document “YB-910 Clean
the flow meter”.
The "Powerdriver » is defective.
The "Powerdriver" power up the
proportional valve.
Measure output PWM between
pin 2 and 3 on J5 "power driver".
(68KHz).
Replace "power driver" PCB AO-
137 if no output.
Proportional water valve
defective
Even if Output OK on the “power
driver” the valve
AN-903 still does not work.
Change proportional valve.
Flow meter is defective
Check by configuring to MAX
water flow 100ml/min in the
“technician menu”. If still no
water flow; Replace AN-119 Flow
meter.
Verify the Flow meter return
voltage on Jumper J7 - Pin 4 and
5 on the bridge PCB AN-368
No flow if the voltage <0.5V
If water on syringe and all other
instruments.
Check the following:
The water flow is set to zero in
the software.
Check in the "technician menu"
that the water flow configuration
is >0.
Refer to "technician menu" on
page 13 for configuration
Water flow properly configured
Check if the electrical connection
between the valve and the
suspension PCB is properly
inserted.
Check it the power on J5 “water
valve” is 24V.
Check the resistance of the coil
if R=0Ω, change the valve. AN-
506.
The instrument bridge PCB is
defective.
Change the “ bridge PCB AN-
368”
