PAGE 9-5
9-2 Basic Operational Tests
Following are the system inspection procedures.
9-2-1 Torque Transducer
AFC3000 system performs a transducer check before each fastening cycle, comparing the calibration
values from the torque transducer stored in the preamplifier memory to the value at that point. (The self
check can be disabled through I/O if needed) The system is maintenance free, however it can be
manually checked using the front display as follows:
These checks should be done without having any mechanical stress on the nutrunner tool.
Zero Torque and Calibration Torque Test
1. Make sure the controller is in READY condition and not able to
get a START signal from the PLC. (Supply STOP signal only)
2. Use the “
◄
“ or “
►
” pushbutton to make the bottom left side of
the display show "Non" (Mon).
3. Use the “
▲
” or “
▼
” pushbutton to make the bottom right side
of the display show "0".
4. Press the "RESET" pushbutton and make sure the value
displayed is near zero. Also, make sure the JUDGE LED turns
green.
5. Press the "CAL" pushbutton and make sure the value
displayed is near the calibration value of the tool. Also, make
sure the JUDGE LED turns green.
You can also check the Origin voltage value or CAL voltage value by the following process.
Zero Level Voltage and Calibration Voltage Test
1. Make sure the controller is in READY condition and not able to
get a START signal from the PLC. (Supply STOP signal only)
2. Use the “
◄
“ or “
►
” pushbutton to make the bottom left side of
the display show "Non" (Mon).
3. Use the “
▲
” or “
▼
” pushbutton to make the bottom right side
of the display show "1".
4. Press the "RESET" pushbutton and make sure the value
displayed is within ± (4%) 150 mV (CFT Tool), 110mV (NFT
Tool) or ± (10%) 375mV (CFT Tool), 275mV (NFT Tool). Also,
make sure the JUDGE LED turns green. This percentage is
selected by the "Zero Level acceptance window selection"
switch on DIP switch SW1 (See Section 4-12-2).
5. Press the "CAL" pushbutton and make sure the value
displayed is near 3.500mV (CFT Tool) or 2.500mV (NFT Tool).
Also, make sure the JUDGE LED turns green.
