･Shielded cable (connectable range:AWG26-20, cross-section area:0.14-0.5mm
recommended. Select the diameter that there is margin in the current capacity. (stripped wire
length is 9mm)
･When using shielded cable, the grounding connection should have a resistance of less than 100
ohms, and grounded one end.
･Connect the wire with pushing the orange color button.
About output of communication error
･In communication style that always perform wireless communication (1:1 topology, 1:1 topology
with repeaters, 1:N topology polling, 1:N topology for report), it outputs the communication error
when wireless communication is cut off continuously.
･Output of communication error and ALARM indication are lighted up at the same time.
･Output of communication error and ALARM indication are turned of the light if wireless
communication is restarted correctly.
･When output of communication error is output, it is possible to select by MODE switch either
"Turn off output signal (OUT0-7 or OUT0-5) coercively" or "Keep state of output that before
communication error is output"
