Chapter 8: Troubleshooting
8.1 Abnormal Display
When an abnormal condition is detected by the system, the affected press 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 [D-NO] display.
• Abnormal code display.
When an Abnormal condition occurs (ABNORMAL LED is lit), the display mode will
automatically 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
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 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.
The main Abnormal codes are:
ABNORMAL
