6. If problem still exists, replace the affected tool. (Refer to Section 8.3)

7. If problem still exists, replace the affected Axis Unit. (Refer to Section 8.3)

9.4.10 Preamp EEPROM Read Abnormal (Axis Unit display code "A3")

Data error has been detected in the tool EEPROM information.

1. Turn off the power and verify the communication bus ribbon cable is in good condition and

is properly connected to both the Main Unit and the AXIS UNIT.

2. Verify that the homerun cables are in good condition and are properly connected to the

Axis Unit and the tool.

3. Remove the Main Unit Multi PCB, and verify the software is compatible with the Axis Unit

PCB. This may be of concern if a component has been replaced.

4. Verify correct installation of all removable IC chips on both the Axis Unit and Multi PCB.

5. Reinstall the Multi and Axis Unit PCBs, as necessary. Ensure that the circuit boards are

properly seated.

6. Ensure that the Main Unit and Axis Unit are not located near any strong electrical or

magnetic fields.

7. Verify correct input voltages and ensure all power cables are properly connected.

8. Turn on the power. If problem still exists, exchange the tool cables with a known good set.

A spare set of cables is normally provided with each System.

9. If problem still exists, replace the affected tool. (Refer to Section 8.3)

10. If problem still exists, replace the affected Axis Unit. (Refer to Section 8.3)

9.4.11 Tool Type Mismatch Abnormal (Axis Unit display code "A3")

Preset tool type and connected tool type are mismatched.

1. Verify that the MACHINE CONFIGURATION / SET SEQUENCE / SET PARAMETER

screens match the physical machine configuration.

2. Re-enter the data on the MACHINE CONFIGURATION / SET SEQUENCE / SET

PARAMETER Screens or reload the Preset files from the PRESET FILE UTILITY screen.

3. Check the connected Axis Units for indications of abnormality. A locked-up display, an

illuminated Abnormal LED, and failure to count down are all possible indicators of a

malfunctioning Axis Unit. If all Axis Units appear to be functional, the problem is likely to

be found in another System component (Refer to Step 4). If some Axis Units appear to be

funtional, use an affected (abnormal) Axis Unit to perform the following inspections,

beginning with Step 12.

4. If all Axis Units appear to be affected, turn off the power. Remove the FC386 and Multi

PCBs, and verify compatibility of software between the two (2) circuit boards. This may

be of concern if a board has been replaced.

5. Verify correct installation of all removable IC chips on both the FC386 and Multi PCBs.

6. Reinstall the FC386 and Multi PCBs. Ensure that the boards are properly seated.

7. Ensure that the Main Unit is not located near any strong electrical or magnetic fields.

8. Verify correct Main Unit input voltage and ensure the power cable is properly connected.
