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 SAN Unit. Data is
not reliable due to data error.
This abnormal is caused from;
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. Reini-
tialize 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 SAN 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 ex-
isted.
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 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. Reini-
tialize the system after each exchange, and make note of any change in the location of the
abnormal.
4. Replace the defective component.
