Move to fully open position at 19.7 mA and over of
the input signal
7.8
Reverse mode (I/R)
7.8.1
It is used when user want to operate actuator by
inverting input signal and output signal.
7.8.2
When the command signal is 4 mA, the actuator moves
to fully open position, and makes 4 mA dc as an
output signal.
7.8.3
When the command signal is 20 mA, the actuator
moves to fully close position, and makes 20 mA dc as
an output signal.

7.9.3
Adjustable setting range of the Zero signal : about 3~8mA dc
7.9.4
Adjustable setting range of the Span signal : about 16~21mA dc
※
Example: Set as the 5 mA dc was apply to Zero, and 19 mA dc was Span signal
①
Confirm the mode knob position as “Stop”.
②
Turn on No 4 (I/S input set) of the DIP SW4.
③
Quickly flickering both of the red and green LED.
④
About 1.5 second later, quickly flickering the green LED only
⑤
