Control Panel
Operation LED: The Operation LED (Yellow) is on when the control output is
on.
Reference color set button: This button is used to memorize the reference
color when the sensor is aimed at a color target. The reference color can also
be registered using an external signal and the set input wire (SET). In either
case, the reference color existing in memory is replaced by the new refer-
ence color.
Inspection tolerance dial: Turn this dial to program one of ve different
degrees of sensitivity. Set the dial to 1 to distinguish the slightest variation in
reference color (narrow range of tolerance). Set the dial to 5 to tolerate con-
siderable variations in the reference color (wide range of tolerance).
Inspection mode switches:
Color only (C): Color only is used to inspect on the basis of color alone,
when surrounding lights inuence intensity , or when the inspection spot
varies.
Color plus intensity (C+I): Color plus intensity is used to inspect on the
basis of color and depth of color when necessary to distinguish between
slight variations in shade.
Synchronous mode switch:
Select external or internal.
External synchronous mode (EXT):
External (EXT) is used to synchronize inspection with an external signal.

1. In the gur e above, "t" represents the amount of time
the external synchronous signals should remain on in
response to the response mode.
F (fast response): 0.2ms or more
N (normal response): 0.5ms or more
S (slow response): 3ms or more
2. To prevent chattering, use a non-contact output
sensor as the external synchronous input.
Internal synchronous mode (INT): Internal (INT) is used to perform
inspections continuously corresponding to the response mode selec-
tion. Internal response is activated when INT is selected and the refer-
ence color set button is pressed.

Response mode switch:
Fast response mode (F): This mode is used for high-speed inspection.
Response time is 0.3ms.
Normal response mode (N): This mode is used for normal inspection.
Response time is 1ms.
Slow response mode (S): This mode is used for stable inspection.
Response time is 5ms.
Off-delay timer (T-ON/T-OFF) switch: This mode is used to select the OFF-
delay timer. The timer maintains the output for 40ms.

Operation at Power ON
The light source does not go on immediately when power is turned on. The
sensor contains a circuit to initially delay the output for two seconds. To
ensure stable sensing, run a test operation for approximately 15 minutes.
