Rated pressure range of switch
Set pressure range of switch
Set the pressure within the rated pressure range.
The set pressure range is the range of pressure that is possible in setting.
The rated pressure range is the range of pressure that satisfies the specifications (accuracy, linearity, etc.) on the switch.
Although it is possible to set a value outside the rated pressure range, the specifications will not be guaranteed even if the value stays within
the set pressure range.

The settings of the master sensor can be copied to the slave sensors,
reducing setting labor and minimizing risk of mistakes in setting.
Can copy to up to 10 switches simultaneously.
(Maximum transmission distance 4 m)
BAuto-preset function (F4)
Auto-preset function, when selected in the initial setting, calculates and stores the set-value from the measured pressure.
The optimum set-value is determined automatically by repeating vacuum and break with the target workpiece several times.

FZero-clear function
This function clears and resets the zero value on the display of
measured pressure.
For the pressure switch with analog output, the analog output shifts
according to the indication.The indicated value can be adjusted
within ±7% F.S. of the pressure when ex-factory. (ZSE40AF (for
compound pressure) ±3.5% F.S.)
Fine adjustment of the indicated value of the pressure sensor can be
made within the range of ±5% of the read value.
(The scattering of the indicated value can be eliminated.)
This function constantly detects and updates the maximum
(minimum) value and allows to hold the maximum (minimum)
pressure value.
When the buttons are simultaneously pressed for 1 second or
longer, while “holding”, the hold value will be reset.
Note) When the display calibration function is used,
the set pressure value may change ±1 digit.

Load current of 80 mA or more is applied to the switch output (OUT1).
Eliminate the cause of the over current by turning

H
A large bore cylinder or ejector consumes a large volume of air in operation and may
experience a temporary drop in the supply pressure. This function prevents detection of
such temporary drops in the supply pressure as an error.
<Principle>
This function averages pressure values measured during the response time set by the user and then compares the average pressure value with
the pressure set point value to output the result on the switch.

Function Details
LAuto-shift function (F5)
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.
JPower-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.)
KSetting of secret code (F81)
Users can select whether a secret code must be entered to release
key lock. At the time of shipment from the factory, it is set such that
the secret code is not required.

second, and the pressure value at that point will be saved as a recti-
fied value “”. Based on the saved rectified values, the set-value Note)
