" Operation".

*2

*1. When connecting a resistor less than 150

may malfunction when power is largely fluctuated.

Cautions 1. The above constants may be changed without notice.

2. The example of connection shown above and the constant do not guarantee proper operation.

Perform thorough evaluation using the actual application to set the constant.
