9.1 Abnormal Conditions.
When an abnormal condition is detected by the system, the affected spindle stops 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. When connected to the AFC Userconsole software, the cause of the abnormal
is also reported via the Fastening Data Monitor screen.

When an Abnormal condition occurs (ABNORMAL LED is lit), the display mode will automati-
cally change to the STATUS mode. (If the display is not in the STATUS mode, depress the
MODE button until a blinking “A” appears in the [PARM] display area) A code number ap-
pears at the right side of the blinking character. This code refers to some specific type of fail-
ure detailed in the tables shown in the following sections.

The number shown at the most right position in the [D-NO] display area 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.
