- ※ AC type proximity sensor cannot be used as the source of count input signals. 

- ※ Input terminal( , )and reset terminal ( , )are insulated 

inside. 

- ※ It is not possible to reset with AC power or DC power. 

- ※ When relay contact is used as the source of RESET signal, please use reliable contacts enough to flow 3VDC 5㎂ of current. 

## **Input from AC type proximity sensor** 

In case of free voltage input type, do not connect AC proximity sensors instead of a switch as shown in the figure 1. It may cause malfunction due to sensor's leakage current. Connect a relay as shown in the figure 2.
