)(& ,QF
This abnormal is caused from only 3 items.
1. When the tool transducer is sensing excessive torque due to pressure on the tool body.
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. Check that the tool has no external force applied to it.
2. Verify that the cable or controller are not located near any high voltage transient power
sources. Relocate as required and reattempt a fastening start input.
3. Exchange transducer (T/D) 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.
4. Replace the defective component.
9.3.5 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>(CODE 1-0) abnormal help procedure.
9.3.6 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>(CODE 1-1) abnormal help procedure.
9.3.7 code 1-6 TORQUE TRANSDUCER / selfcheck ZERO ERROR
Zero level voltage error during power on initialization.
This abnormal is caused from only 3 items.
1. When the tool transducer is sensing excessive torque due to pressure on the tool body.
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. Check that the tool has no external force applied to it.
2. Verify that the cable or controller are not located near any high voltage transient power
sources. Relocate as required and reinitialize.
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.
