9.2.8 EEPROM Write Error

Data write error occurred while attempting to write to the Multi PCB EEPROM.

1. Enter the preset data required for the specified screen.

2. If problem still exists, turn off power. Remove the FC386 and Multi PCBs, and verify

compatibility of software between the two (2) circuit boards. This may be of concern if

boards have been replaced.

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

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

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

6. Turn on the power. If problem persists, replace the Multi PCB. (Refer to Section 8.3)

7. If problem still exists, replace the FC386 PCB. (Refer to Section 8.3)

8. If problem still exists, replace the entire Main Unit. (Refer to Section 8.3)

9.2.9 No Statistics Data

Statistic analysis cannot proceed because of a lack of fastening data.

1. A minimum of 7 fastening cycles are required for the statistical analysis data calculation.

2. The System must be cycled at least one time for a fastening torque curve to be displayed.

3. If the problem still exists, turn off power. Remove the FC386 and Multi PCBs, and verify

compatibility of the software between the two (2) circuit boards. This may be of concern if

boards have been replaced.

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

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

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

7. Turn on the power. If problem persists, replace the Multi PCB. (Refer to Section 8.3)

8. If problem still exists, replace the FC386 PCB. (Refer to Section 8.3)

9. If problem still exists, replace the entire Main Unit. (Refer to Section 8.3)

9.2.10 Run Mode

Data presets and changes cannot be made with the System operating in the RUN mode.

1. Verify that the Machine is not busy performing a fastening cycle.

2. Place the RUN / PROGRAM switch into the PROGRAM position. Enter the desired data,

then place the switch back into the RUN position.

3. If problem still exists, turn off power. Remove the FC386 and Multi PCBs, and verify

compatibility of software between the two (2) circuit boards. This may be of concern if

boards have been replaced.

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