WARNING:

DO NOT CONNECT OR DISCONNECT CABLES OR OTHER SYSTEM

COMPONENTS WITH POWER APPLIED.

9.4.9 FULL SCALE TORQUE OVER ABNORMAL (axis Unit display code "a1")

MEasured torque exceeded full scale (CALIBration) torque.

1. Verify that the tool is properly secured to the mounting plate, and that there is no sign of

stress or misalignment. Ensure that there is no tool movement while the self-check is

being performed.

2. Turn off the power. Verify that the homerun cables are in good condition and are properly

connected to the Axis Unit and the tool.

3. ensure that the Axis Unit is not located near any strong electrical or magnetic fields.

4. Verify Axis Unit input voltage and ensure the power cables are properly connected.

5. If problem still exists, exchange the tool cables with a set that is known to be good. A

spare set of cables is normally provided with each System.

6. If the problem still exists, replace the affected tool. (Refer to Section 8.3.4)

7. If the problem persists, replace the affected AXIS UNit. (Refer to Section 8.3.3)

9.4.10 PREAMP EEPROM READ ABNORMAL (axis Unit display code "a3")

DAta error has been detected in the tool EEPROM information.

1. Verify that the communication bus ribbon cable is in good condition and is properly

connected to the ISA MAIN and AXIS UNITs.

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

Axis Unit and the tool.

3. ensure that the ISA Main and Axis Units are not located near any strong electrical or

magnetic fields.

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

5. If the problem still exists, exchange the tool cables with a set that is known to be good. A

spare set of cables is normally provided with each System.

6. If the problem still exists, replace the affected tool. (Refer to Section 8.3.4)

7. If the problem persists, replace the affected Axis Unit. (Refer to Section 8.3.3)
