DIAGNOSIS

¶

Confirmation of Single Display of LED

1. DC+10V is impressed for 1 pin (GND) and 5 pin (+10V) of the CN001.

2. GREEN single display: +5V is impressed to the CN001 2 pin.

3. BLUE single display: +5V is impressed to the CN001 3 pin.

4. RED single display: +5V is impressed to the CN001 4 pin.

¶

Attention When Diagnosing

• Handle LEDs carefully because it is weak to static electricity.

• Do not impress +5V to each terminal (2, 3, and 4 pins) at the same time.

• The LED might be destroyed when impressing at the same time.

• When the LED is destroyed partially, brightness falls.(It is incomprehensible in single color.)

NOTES:

Parts marked by "NSP" are generally unavailable because they are not in our Master Spare Parts List.
The mark found on some component parts indicates the importance of the safety factor of the part.
Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.
Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).
