FIG. 7-1 Operational controls and indicators
7.1.1 Manual Fastening controls.
wSTART.
This push-button initiates the fastening cycle.
wREV (Reverse).
Manual reverse. While this push-button is depressed, the nutrunner turns in the
counter-clockwise direction.
wCAL (Calibration).
CAL voltage checking push-button. Depress this push-button to obtain the CAL voltage
level of the tool pre-amplifier. This level is compared to the data stored in memory. If the
difference is within the allowed range the accept LED will light, otherwise the REJECT LED
will light. The calibration voltage level is converted to the full-scale torque, according to the
parameter setting and is shown in the "DATA" display.
wRESET.
This is used to reset the Axis unit. If this key is pressed during fastening, the process will
stop, and all the fastening data and output signals will be reset. At the same time, the Zero
level of the torque transducer will be checked. If it is within the acceptable range, the
ACCEPT LED will light. If it is not within range, the torque REJECT LED will light.

7.1.2 Fastening Indicators.
wBUSY LED (Yellow).
Indicates when the Axis unit is performing a fastening or reverse operations.
wABNORMAL LED (Red).
Indicates when an abnormal condition occurs during fastening or during the system SELF
CHECK function.
wACCEPT LED (Green).
Indicates when the fastening results are within acceptable limits.
wBYPASS LED (Red).
Indicates by flashing when the Axis unit is in a bypass condition.
wTORQUE LED (Orange and red).
Orange indication represents a LOW TORQUE REJECT as the fastening result.
Red indication represents a HIGH TORQUE REJECT as the fastening result..
wANGLE LED (Orange and red).
Orange indication represents a LOW ANGLE REJECT as the fastening result.
Red indication represents a HIGH ANGLE REJECT as the fastening result.
Chapter 7: System Operations (Rev. 8/98)
w1ST RATE LED (Orange and red).
Orange indication represents a LOW 1ST RATE REJECT as the fastening result.
Red indication represents a HIGH 1ST RATE REJECT as the fastening result.
w2ND RATE LED (2ND RATE).
Orange indication represents a LOW 2ND RATE REJECT as the fastening result.
Red indication represents a HIGH 2ND RATE REJECT as the fastening result.
wTIME LED.
Orange indication represents a 1ST TIME REJECT as the fastening result.
Red indication represents a FINAL TIME REJECT as the fastening result.
7.1.3 Fastening Preset / Result displays.
w[D-NO] Data number indicator (2 digits).
Indicates the Display mode and data type by number.
w[DATA] Data value indicator (4 digits).
Displays the current torque value of the torque transducer while in the real-time indication
mode. Displays the data specified by [D-NO] while in the fastening data indication mode.
w[PARM/ABN] Parameter number/abnormal number indicator (1 digit).
Display for the parameter number of the last fastening. If an abnormal condition occurs, it
shows the abnormality number.

7.2 Run State Modes.
The AFC 1100 system has two operational states that are controlled by the selection of the
Run/Bypass switch on the front of the Axis unit or by the PLC Bypass input. The operational
modes availible in the Run State are identified below. Under this condition the BYPASS
switch on the front panel is in the RUN position and the BYPASS external signal is not active
(the BYPASS LED is off). During the RUN condition, the display mainly shows the results of
fastening, abnormalities, preset values, etc.
7.2.1 Display indication modes.
Three modes can be selected while in the RUN state by pressing the MODE push-button.
