SINK (Negative) logic/SOURCE (Positive) logic (When an external power supply<br />

is used)<br />

The PLC terminal is used to connect to an external power supply or to insulate a terminal from other input<br />

or output terminals. As for input terminals, turn the SW4 slide switch to the PLC position.<br />

Selecting the functions of the VIA terminals between analog input and contact<br />

input<br />

The functions of the VIA terminal can be selected between analog input and contact input by changing<br />

parameter settings (). (Factory default setting: Analog input)<br />

When using these terminals as contact input terminals in a sink logic circuit, be sure to insert a resistor<br />

between the P24 and VIA terminals. (Recommended resistance: 4.7KΩ-1/2W)<br />

In case source (Positive) logic circuit, connect the resistor between VIA and CC terminals.<br />

When using the VIA terminal as a contact input terminal, be sure to turn the VIA (SW3) switch to the V<br />

position. If no resistor is inserted or the VIA (SW3) slide switch is not turned to the V position, contact input<br />

will be left always ON, which is very dangerous.<br />

Switch between analog input and contact input before connecting the terminals to the control circuit<br />

terminals. Otherwise the inverter or devices connected to it may be damaged.<br />
