Auto-shift function (F5) (Z/ISE20A, 20B, 20C series only)
When there are large fl uctuations in the supply pressure, the switch
may fail to operate correctly. The auto-shift function compensates for
such supply pressure fl uctuations. 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.
When the auto-shift function is selected, “
” will be displayed
on the sub screen for about 1 second, and the pressure value at that
point will be saved as reference value “ .” Based on the saved
reference value, output on-off points controlled by set values

such
as “ ,” “ ,” “ ,” and “ ” will also be rectifi ed.
∗2 When an output is reversed, output on-off points displayed at
“ ,” “ ,” “ ,” and “ ” will be rectifi ed.
The above is an example in hysteresis mode. On-off points are
similarly rectified in window comparator mode. Outputs that
enable the auto-shift function can be changed via the settings.
Auto-shift zero
The basic function of auto-shift zero is the same as that of auto-
shift. However, it corrects values on the display based on a
pressure value of “
”, which is set as the reference value when
auto-shift function is selected.

Copy function (F97) (Z/ISE20A, 20B, 20C series only)
The settings of the master sensor can be copied to the slave sensors,
reducing setting labour and minimising the risk of setting mistakes.
The set value can be copied to up to 10 switches simultaneously.
(Maximum transmission distance: 4 m)
1) Wire as shown in the fi gure on the left.
2) Select the slave sensor which is to be the master, and change it
into a master using the buttons. (In the default setting, all
sensors are set as slaves.)
3) Press the button on the master sensor to start copying.
