A command has been transferred to the MULTI board that is either not recognized or is

impossible to respond to due to the machine configuration. Example: Invalid/out of range

preset data for the configured equipment.

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

screens match the physical machine configuration.

2. Reenter the data on the MACHINE CONFIGURATION / SET SEQUENCE / SET

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

3. 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. Check Main Unit input voltage and power cable connection.

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

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

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

9.2.4 Fastening Error

AN attempt was made to change the pREset data during the fastening process.

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 previously 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)

9.2.5 Upload Error

Fastening has not been performed, or the data that has been collected cannot be processed.

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
