preset number stops flashing. Now press the footpedal
to turn on the motor and LED and then release it and
verify that the LED remains on for 20 +/-5 seconds.
9.
Place the motor into a calibrated ATU-0037
tachometer. Confirm that the torque is set to 100%.
Set the speed to 40.0KRPM. Press the footpedal to
turn on the motor and record the speed which the
tachometer shows and verify that it is 40.0KRPM +/-
2.0KRPM. Values outside this range are non-
conforming.
10.
Attach an Anthogyr 8:1 (actually 7.2:1) handpiece to
the motor and set the controls to 8:1 ratio, 500RPM,
100% torque and ENDO mode. Attach the handpiece
to the bit on the dynamometer assembly (copper
cylinder) and press the footpedal. While the motor is
running, decrease the Torque% setting until the motor
stops and goes into ENDO mode. Record the Torque
% setting where this happens. It should be less that
50% and greater than 5%. If not, remove the
handpiece and lubricate it with Aseptispray and repeat.
If it still fails, mark it as nonconforming.
11a
. Remove the handpiece. Depress the foot pedal
with the Handpiece Water and Handpiece Air toggle
valves off and check that no cooling air or water is
coming from the two holes between the 0-rings on the
motor E-head. You will feel motor cooling air at the
front of the E-head however.
11b.
Turn the Handpiece Air toggle valve on and adjust
the Handpiece Air needle valve on the Delivery Module.
Depress the footpedal and verify that air is coming from
the motor E-head hole between the two o-rings farthest
from the motor body on the E-head.
11c.
Partially fill the Delivery Module water bottle and
insert an internal irrigation type handpiece such as the
AHP-72MB onto the motor. Turn the Handpiece Air
toggle valve off and the Handpiece Water toggle valve
on and adjust the Handpiece Water needle valve on the
Delivery Module. Depress the footpedal and verify that
water is coming from the handpiece. Turn on the
Handpiece Air and verify that a fine mist is coming from
the handpiece.
11d.
Operate the handpiece motor with the Handpiece
Air toggle on and then turn the toggle off while still
operating the motor. Release the foot pedal and place
the hand motor firmly in its holder and wait 5 seconds.
Press the footpedal. If the motor comes on, the
designed leak isn’t present or of adequate magnitude.
11e.
Turn off the AEU-525 and trip the HVE and bottle
pressurization toggles to remove all compressed air
from the system. Close the toggles. Fill the ATU-0088
bottle to the line on the side and mount on the AEU-
525. Turn on the AEU-525 and observe the final
pressure of the ATU-0088 gauge. It should be between
25 and 35 PSI and should be reached within 10
seconds of turn on. Repeat steps 4 more times. If
pressure is wrong or it takes too long to pressurize then
the module needs to be reworked.
12.
Simultaneously hold the Preset and Ratio buttons
until the display resets and factory defaults are set.
F. Performance Test (Syringe):
1.
Fill the water bottle and turn on the compressor to fill
the air reservoir. Press the syringe air button (the right
one) and check that the pressure gauge doesn’t go
below 20 PSI. If it does, change the screwdriver adjust
for the syringe air.
2.
Release the syringe air button and allow the
compressor to refill the reservoir. Press the syringe
water button (left one) and verify that water comes out
the syringe.
3.
Press both buttons and verify that a mist is created.
4.
Use ATU-0090 and plug the syringe tip into the
syringe. Press the syringe air button and observe the
MAXIMUM pressure on the gauge. It must be between
48.0 and 55.5 PSI
G. Performance Test (Scaler):
1.
Remove scaler from its holder, install a tip, turn the
scaler intensity to “10”, turn the Scaler Water control
counterclockwise as far as it will go, turn the Scaler
Water toggle valve on and press the foot pedal and
observe that the scaler produces water from the tip, that
the scaler lights come on, and that when the scaler tip is
placed against a thin metal surface, there is high pitched
noise produced.
2.
Turn the Scaler Intensity control from “10” to “100”
and back and verify that the control adjusts the intensity
of the scaler vibrations.
3.
With the Scaler Intensity control set to “10”, adjust the
Scaler water control clockwise and counterclockwise to
verify that it controls the amount of water coming from
the scaler tip.
4.
Press the foot pedal several times to verify that the
scaler goes on and off with no more than a ½ second
delay. Remove the scaler tip
H. Performance Test (Waste Tank)
1.
Remove the Waste Tank lid from the tank and with
the floats at the bottom place the .82“ spacer over the
sensor wells and then press each float upward as far as
possible. There must be no alarms. Remove the .82”
spacer and lift each float about .250” and there must be
flashing from the red LED on the lid and beeping from
the main case.
2.
Turn on the HVE so that the compressor is on
continuously and place a .0625 spacer above the first
float and raise the float as high as possible. The
compressor must stop.
3.
Repeat for other float.
I. HiPot and Ground Bond Tests:
1.
On the AC/DC Withstand Voltage Tester, press MENU
-> MENU -> SYSTEM and change the “PLC REMOTE”
setting to “OFF”.
2. Ground Bond Test
- Earth Ground at Power Inlet to
accessible earthed metal.
Test parameters:
Current limit 25 Amps, Dwell time 2
seconds, Resistance limit 0.1 Ohms.
