Auto-shift function (F 5)
When there are large fluctuations in the supply pressure, the switch
may fail to operate correctly. The auto-shift function compensates
such supply pressure fluctuations. It measures the pressure at the
time of auto-shift signal input and uses it as the reference pressure
to correct the set-value on the switch.
Auto-shift zero
The basic function of auto-shift zero is the same as the function for
auto-shift. Also, it corrects values on the display, based on a
pressure value of “ ”, when the auto-shift is selected.

Power-saving mode (F80)
Power-saving mode can be selected.
It shifts to the power-saving mode without button operation for 30
seconds. It is set to the normal mode (Power-saving mode is OFF.)
when ex-factory. (Decimal points and operation indicator light (only
when the switch output is turned ON.) blink in the power-saving
mode.)
K
Secret code setting (F81)
It can be set whether secret code input is required or not when key is
locked. It is set to input no secret code when ex-factory.

Rectified value
When the auto-shift is selected, “ ” will be displayed for about 1
second, and the pressure value at that point will be saved as a
rectified value “ ”. Based on the saved rectified values, the set-
value
Note)
of “ ”, “ ”, “ ”, and “ ” will likewise be rectified.
Note) When an output is reversed, “ ”, “ ”, “ ”, “ ” will be
rectified.
The F
