9.2.4 Code 1-3 TORQUE TRANSDUCER / CAL SELF CHECK ERROR
Calibration Level Voltage error after a fastening start was attempted.
This abnormal is caused from;
1. When the tool transducer is sensing excessive torque due to pressure or vibration during
the fastening cycle start.
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. Check that the tool has no external force applied to it.
2. Verify the tool mounting bolts are tight and nothing is causing excessive vibration to the
tool.
3. Verify that the cable or controller is not located near any high voltage transient power
sources. Relocate as required and attempt a fastening start input again.
4. Exchange tool cable, tool and/or controller with known working units. Input the start input
after each exchange and make note of any change in the location of the abnormal.
5. Replace the defective component.
9.2.5 Code 1-4 TORQUE TRANSDUCER/STARTED ON ZERO ERROR CONDITION
The start signal was input while a Zero Voltage Abnormal condition existed.
RECOVERY:
1. Interlock the PLC circuit to disable the start signal during an existing abnormal condition.
2. Follow the ZERO VOLTAGE ERROR abnormal help procedure.
9.2.6 Code 1-5 TORQUE TRANSDUCER / STARTED ON CAL ERROR CONDITION
The start signal was input while a CAL Voltage Abnormal condition existed.
RECOVERY:
1. Interlock the PLC circuit to disable the start signal during an existing abnormal condition.
2. Follow the CAL VOLTAGE ERROR abnormal help procedure.
9.2.7 Code 1-6 TORQUE TRANSDUCER / ZERO LEVEL SELF CHECK ERROR
Zero Level Voltage loaded to memory from tool EEPROM during initialization does not match the
actual zero level during a self check with the self check function enabled.
This abnormal is caused from;
1. When the tool transducer is sensing excessive torque due to pressure on the tool body.
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. Check that the tool has no external force applied to it.
2. Verify that the cable or controller is not located near any high voltage transient power
sources. Relocate as required and reinitialize.
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.
