3. INSTALLATION
1st Edition : Oct. 27, 2023-00
The converter receives a contact signal and performs the configured function.
Cable specifications:
Each CH requires two cores for this wiring.
Select the number of cores according to the number of contacts to be used.
Wiring instructions:
(1) The terminal screw of the converter is an M3 screw. The tightening torque is 0.6 N•m.
Use crimp terminals compatible with these screws to terminate the cable.
(2) Resistance or voltage values determine the “ON/OFF” of this contact input.
Switches must meet the conditions shown in the table below.

This terminal block has the following three functions.
● Analog input ( O
2
analyzer: available when “-1” or “-2” is selected)
When using an external oxygen meter to input the O
2
detector, use this terminal for current input
(4-20 mA). Set the 20 mA oxygen concentration to 100% in the external oxygen meter setting.
Cable specifications:
Use two-core cables for this wiring.
Wiring instructions:
(1) Use an M3 screw for the terminal screw of the converter. The tightening torque is 0.6 N•m.
Use crimp terminals compatible with these screws to terminate the cable.
(2) Do not wire with reversed polarity. Wire carefully to avoid mistaking the “+” and “-” polarity.
