Electrical wiring of the device is completed (see the “Wiring method” below).

There is an input signal from the controller (constant-current supply).
Note) If there is no 4 to 20 mA DC signal from the controller, connect a constant-current supply
(3.85 to 21.5 mA DC) to the input signal terminal. When doing so, be sure to remove the
wires coming from the controller off of the terminals.
