My System's Abnormal LED is lit.  How do I find out what the abnormal was without the AFC Software?

The Axis Unit can display an abnormal code when the display unit is attached to the Axis Unit.  The Code will indicate the cause of the abnormal condition.

From section 7.1.3 of the manual.
FASTENING PRESET / RESULT DISPLAYS.

• [D-NO] Data number indicator (2 digits).

Indicates the Display mode and data type by number.

• [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.

• [PARM] Parameter number/abnormal number indicator (2 digits).

Display for the parameter number of the last fastening. Also indicates if an abnormal condition occurs. When the CAL switch is pressed, "E" is shown if the FULL-SCALE preset value is missing or a wrong tool is connected (Refer to Chapter 9).

From section 9.1 of the manual.
ABNORMAL CONDITIONS

When an abnormal condition is detected by the system, it halts and lights the ABNORMAL LED. For ease of troubleshooting the nature of the abnormal, the system provides an abnormal code in the [PARM] display and an abnormal sub-code in the [DATA-NO] display.

• Abnormal code display.

When an Abnormal condition occurs (ABNORMAL LED is lit), go to the STATUS mode by depress the [MODE] key several times until a blinking "A" appears in the [PARM] display. A code number appears at the right side of the blinking character. This code refers to some specific type of failure detailed in the tables shown in the following sections.

• Abnormal Sub-code display.

The number shown at the most right position is a sub-code that can be used in conjunction with the Abnormal failure code to further narrow down the cause of the fault. See the following sections.
