Basic Operation
Inhibit This default function means that pin 5 of
the P-IO controls the operation of the
instrument.
Living Select Living, and load will be
operated in the mode of Living.
Latch Select Latch, and load will be
operated in the mode of Latch.
Input Pin 5 receives the level signal from the
outside.
Output Pin 5 sends the digital signal (1, 0, PWM)
to the outside.
True By default (Not-Invert), the out-
put digital signal is 1 (i.e. low
level), and in the case of Invert,
the output is high level.
False By default (Not-Invert), the out-
put digital signal is 0 (i.e. high
level), and in the case of Invert,
the output is low level.
PWM Digital signal of PWM.
PWM Freq Frequency
PWM Duty Duty cycle
How to Use
• When pin 5 is set to Inhibit-Living (Not-Invert), pin 5 can control the instru-
ment’s input state based on the level signal from external input.
– Under default conditions (namely, pin 5 is not connected), the input is
high level, and it will not impact the instrument’s input state.
– When the [On/Off] is in On state, input low level to pin 5, and it will im-
pact the input state: The [On/Off] button light is lighted on and VFD still
displays On, but the actual input is 0; when pin 5 receives high level sig-
nal again, the input state is recovered.
