9.4 Tool EEPROM Errors
9.4.1 Code 3-0 PREAMPLIFIER / TOOL ID CHECKSUM ERROR
Communication data checksum error between the Preamplifier and the MNR Unit. Data is not
reliable due to data error.
This abnormal is caused from;
1. If the controller or the tool cable is located in an electrical or magnetic noise field.
2. When the torque transducer, tool cable or the controller malfunctions.
RECOVERY:
1. Verify that the cable or controller is not located near any high voltage transient power
sources. Relocate as required and reinitialize the system.
2. Exchange tool 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. 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 located on Data Display (see 7.2.5)
3. Program proper tool number into MNR Unit or change tool to proper tool.
9.4.3 Code 3-2 STARTED WITHOUT TOOL CONNECTED
The start signal was applied while a TOOL IS NOT CONNECTED abnormal condition existed.
RECOVERY:
1. Interlock the PLC circuit to disable the start signal during an existing abnormal condition.
2. Follow the TOOL IS NOT CONNECTED (Code 3-3) abnormal help procedure.
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;
1. The tool cable is not connected
2. If the controller or the tool cable is located in an electrical or magnetic noise field.
3. When the torque transducer, tool cable or the controller malfunctions.
RECOVERY:
1. Verify that the tool cable is connected.
2. Verify that the cable or controller is not located near any high voltage transient power
sources. Relocate as required and reinitialize the system.
3. Exchange tool 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.
