9.5 System Memory / Tool EEPROM
9.5.1 code 4-0 system memory error / tool eeprom write error
Communications error between the tool preamplifier and the controller.
This abnormal is caused from only 2 items.
1. If the controller or the transducer cable is located in an electric or magnetic noise field.
2. When the torque transducer, transducer (T/D) cable or the controller malfunctions.
RECOVERY:
1. Verify that the cable or controller are not located near any high voltage transient power
sources. Relocate as required and reinitialize the system.
2. Exchange transducer (T/D) cable, tool and/or controller with known working units.
Reinitialize the system after each exchange, and make note of any change in the location of
the abnormal.
3. Replace the defective component.
9.5.2 code 4-1 system memory error / tool eeprom read error
Communications error between the tool preamplifier and the controller.
This abnormal is caused from only 2 items.
1. If the controller or the transducer cable is located in an electric or magnetic noise field.
2. When the torque transducer, transducer (T/D) cable or the controller malfunctions.
RECOVERY:
1. Verify that the cable or controller are not located near any high voltage transient power
sources. Relocate as required and reinitialize the system.
2. Exchange transducer (T/D) cable, tool and/or controller with known working units.
Reinitialize the system after each exchange, and make note of any change in the location of
the abnormal.
3. Replace the defective component.
9.5.3 code 4-2 system memory error / power on ram check error
Verification error while reading/writing the controller RAM.
This abnormal is caused from only 2 items.
1. If the controller is located in an electric or magnetic noise field.
2. When the controller malfunctions.
RECOVERY:
1. Verify that the controller is not located near any high voltage transient power sources.
Relocate as required and reinitialize the system.
2. Exchange the controller with known working unit. Reinitialize the system after the
exchange.
