How to set contact input (MC-3020D)
Use the connectors J3 to J6 on the MC-DIN Board (24P0116) to set the contact input.
See the tables on the next page.
Note 1: For contact input, use the AWG24 wire for jumper.
Note: The input must not exceed the range of the input voltage, to prevent malfunc-
tion.
-Setting for voltage input: 21.6V to 31.2V
-Setting for contact input: Voltage cannot be input (contact signal only).
