Preamplifier / Tool EEPROM
9.4.1 code 3-0 preamplifier / tool eeprom 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.
9.4.2 code 3-1 preamplifier / tool type error
The connected tool type does not match the tool type programmed into the controller
connected to that tool. This error may occur in the multi tool type application or when
controllers are replaced and not reprogrammed with the correct configuration.
RECOVERY:
1. Verify the tool type name from the tool identification tag
2. Compare the tool tag name with the setup value. Refer to section 7.3.6.
9.4.3 code 3-2 preamplifier / started without tool connected
The start signal was applied while a
RECOVERY:
1. Interlock the PLC circuit to disable the start signal during an existing abnormal condition.
2. Follow the
9.4.4 code 3-3 preamplifier / tool is not connected
Communications error between the tool preamplifier and the controller.
This abnormal is caused from only 3 items.
1. The transducer cable is not connected
2. If the controller or the transducer cable is located in an electric or magnetic noise field.
3. When the torque transducer, transducer (T/D) cable or the controller malfunctions.
RECOVERY:
1. Verify that the transducer cable is connected
2. Verify that the cable or controller are not located near any high voltage transient power
sources. Relocate as required and reinitialize the system.
3. 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.
4. Replace the defective component.
