Using the PC terminal
This terminal is used to connect transistor output (open collector output)
such as a programmable controller (PC). Connecting the external power
supply common for transistor output to the PC terminal prevents a faulty
operation caused by a sneak current.
(The power supply voltage of the PC terminal should be 24VDC.)
Instruction for contact inputs
Since input signals to the control circuit are at a low level, use two parallel
micro signal contacts or twin contact for contact inputs to prevent a contact
fault.
