6 TROUBLESHOOTING

When in trouble:

This section describes the measures to be taken when this sensor does not
operate properly or cannot detect a work due to some reasons.
Color cannot be selected well.
The color selection window may be too large.
• Reduce the size of the window and mach it to the intended color.
The color range may be too wide.
• Reduce the set value of COLOR% P(Width of the detection color for
the position correction) for the position & magnification corrections
and the set value of COLOR% R (Width of the detection color for the
rotation correction) for the rotation correction.
The screen may be dark.
• If the screen is dark, it is more difficult to detect the target color since
noise element increases. Reduce the set value of IMG GAIN (Image
sensor gain) and add the external lighting or make the distance to the
work closer.
• If the set value of DARK CMP (Darkness correction ratio) is too large,
a dark color cannot be detected. When a dark color is selected, set this
value to "20" to "24".
Color is not detected at a part in the screen.
The color detection area may be limited with COLOR WINDOW on
the teaching menu.
• Set the color detection area again since it is switched over for each
bank.
The brightness may be irregular at the edge in the screen by the
lighting.
• There is a case where the intended color is not detected due to the
brightness irregularity. Execute the brightness irregularity correction
on the system menu.
Position, magnification, and rotation corrections shift
gradually.
Confirm that the detection color when the teaching is done is
correctly detected.
