GENERAL SERVICE INFORMATION

This service and parts manual offers information and parts lists not available in the AEU-25 Endo DTC Operation and Maintenance Instruction Manual. It will help you better understand how the Endo DTC Unit works, thereby reducing service time. Parts are listed and referenced to callouts in the Parts List. Use the information in the Parts List when ordering replacement parts.
Inspection & Operation Verification
To verify that the Endo DTC unit is functioning properly, follow the set-up procedure in the Operation & Maintenance manual. First, check that the voltage selector is set to the proper voltage. Turn the fuseholder until the white lettering  with the proper voltage is right side up. Use 115V for 110-120V 60 Hz voltages, and the 230V for 220-250V 50Hz voltages. Attach the power cord to the back of the console and plug into a grounded electrical outlet. Connect the AE-4B-30  motor to the receptacle on the lower front panel of the console. Attach the ‘E’ Type handpiece to the motor. Attach the supplied AE-7P On/Off foot switch to the connector on the back of the unit marked “Foot Switch”. Turn the power  switch on the rear panel of the console ‘On’ (-) position. The console LCD display should light up and the startup screen will be displayed for a few seconds. The screen should display the software version onboard your Endo DTC:
ASEPTICO AEU-25
Software Rev. (-Revision Number-)
Press, hold, and release the “CAL” button to enter the System Setup Menu. Follow the menu commands displayed on the screen to select appropriate menu options (refer to Operation and Maintenance Instruction Manual). Insert an endodontic rotary file into the handpiece. Use the calibration function (“CAL” button) to calibrate the Endo DTC (refer to “FILE LIBRARY” and “OPERATION” chapters in the Operation Manual for complete file library selection and calibration instructions).
The above procedures describe basic inspection and verification of the Endo DTC. If the unit still does not perform as required, further diagnosis of components in the system may require service. Use the Troubleshooting section as a  guide to symptoms and appropriate procedures to fix various problems.

Cleaning and Lubrication
When servicing the Endo DTC unit, a hot detergent solution or alcohol are effective cleaners on all non-electrical parts. Abrasive cleaners have the potential to damage surface finishes and should be avoided. Any wiping should be done  with a soft lint-free cloth.
Electrical parts should be cleaned with an appropriate electrical parts cleaner or air. Use a silicone base lubricating grease, such as Dow Corning No. 103 to lubricate O-rings and seals on handpieces. Before performing any reassembly of  parts that contain O-rings or seals, apply a light coat of silicone grease.
This will make installation easier and prevent the O-rings or seals from being damaged.

The Endo DTC power PCB board may be the source of the problem. For troubleshooting procedures specific to the PCB board, refer to the PCB testing chart on page 7.
   

MOTOR FIELD TESTING

NOTE: Endo DTC motor testing in the field is limited to simple manual and visual tests that help to determine the source of the problem. We recommend that the motor/cord assembly be returned to Aseptico for all repairs. Do not attempt to disassemble the motor assembly.

1. Motor Rotation Test: This test can be performed manually using a simple turning tool that can be improvised in the field or procured from Aseptico. The tool needs to be able to grasp the motor’s internal rotor/magnet assembly and  rotate it to determine if the assembly is damaged.
   Insert tool into motor tip and engage rotor shaft as shown in Figs. 19A & 19B. Turn tool back and forth to determine if rotor assembly moves freely (Fig. 19C). If resistance is felt, return motor/cord assembly to Aseptico for repair.

2. Connector Pin Test: This test consists of a simple visual check of the pin condition of the motor/cable connector socket on the lower front of the Endo DTC console.
   Refer to Figs. 20A, -B, and -C to determine if pins appear damaged. If pins cannot be repaired or the connector wiring assembly replaced in the field, return the unit to Aseptico for repairs.
   

REPROGRAMMING THE UNIT

The Endo DTC provides a Field Programming tool (Ref PN AEU-25FP) that enables a technician to reprogram the Endo DTC software in the event the existing software is accidentally erased or corrupted. To reprogram the unit, follow the steps below:

1. Install a standard 9 Volt battery onto the Programmer (Fig. 21). The red and green LEDs will illuminate for approximately 30 seconds and then turn off.
2. Turn the Endo DTC unit over to expose the chassis bottom. Locate and remove the plastic hole plug with a slot-head screwdriver or other thin-edged tool. (Fig. 22).
3. Carefully insert the Programmer into the hole as shown in Fig. 23 and plug 4-pin socket into 4-pin connector port located on printed circuit board below. NOTE: The PCB includes a pin guide which prevents misalignment of the  Programmer socket to the 4-pin connector (See inset in Fig. 23).
4. Press the small button switch located at the top end of the Programmer to initiate software download into the Endo DTC unit. (Fig. 24 The red and green LEDs will flash rapidly as the program downloads. If reprogramming was  successful, the green LED will illuminate after the flashing stops, or if unsuccessful, the red LED will light.
5. Once reprogramming is completed, remove Field Programming tool, reinstall programming port plug, and place Endo DTC unit upright on its base. Turn unit power ‘On’ and ensure that the proper software level is shown on the  startup screen.
   

HI-POT TEST (DIELECTRIC WITHSTAND VOLTAGE TEST)

WARNING
Dangerous voltages are present during the following Hi-Pot testing. Severe electric shock can result and could prove fatal. Only qualified technicians should perform these tests.

The Hi-Pot (High Potential) test should be performed each time a new power PCB board or transformer are installed in the DTC unit. Hi-Pot testing consists of two separate test routines, typically performed in tandem via two Hi-Pot test/measurement devices:

1. Dielectric Withstand Voltage Test – This test stresses the Endo DTC unit’s insulating material beyond what it will ncounter duing normal operation. It assures that the unit will withstand higher than normal voltage potentials before flashover or breakdown. To test the Endo DTC, set up the unit and test equipment as shown in Figures 25 & 26.
   NOTE: Test equipment shown in example is the Associated Research, Inc. Model 3665 AC/DC Withstand Voltage Tester and Model 3130 Ground Bond Tester.
   Configure the hi-pot tester to apply 3000 VAC for one second across the mains (appliance inlet) and the applied part (motor shaft), with the leakage trip level at the applied part set at 1.0mA.
   NOTE: Ensure that the above test parameters are set up correctly before operating the test.

2. Ground Bond Test – This test is performed between the earth terminal on the appliance inlet and the applied part.
   Configure the ground tester to apply 25Amps at 6VAC for two seconds, with a limit of 0.1 Ohm.
   NOTE: Ensure that the above test parameters are set up correctly before operating the test. Also, it may be necessary to offset the resistance of the power cord to achieve accurate readings.
   IMPORTANT: Any system that fails either of the above tests must be removed from service and thoroughly examined, repaired and retested by a qualified technician.
