How to set contact input/output
The connector J11 can be used for the connection of contact input or voltage input.
Refer to the figures shown below to make the wiring which complies with the input
specification.
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).
• (Setting for contact input)
Use NH connector
and AWG24 wire.
