❈ Terminals 3 and 12 share the COM1 signal in common.
❈ Terminals 21 and 2 are isolated from each other.
• The 0-V power supply, COM1, and COM2 signals are common
in voltage through a choke coil. Check that there is no potential
difference between them.
• All unused terminals must be open. Do not connect any wires
to them, otherwise the LS-7000 Series may malfunction.
