Set Pressure Range and Rated Pressure Range
Set the pressure within the rated pressure range.
The set pressure range is the range of pressure within which setting is possible.
The rated pressure range is the range of pressure that satisfies the specifications (accuracy, linearity, etc.) of the switch.
Although it is possible to set a value outside the rated pressure range, the specifications cannot be guaranteed even if the value stays within the set pressure range.

Functions
Sub screen setting function
Auto-preset function
The display of the sub screen can be selected.
This function calculates a rough set value automatically based on the on-going operation.
Display value fine adjustment function
Evens out deviations in the displayed value
Peak value indication function
Can retain the maximum pressure value displayed during measurement
Bottom value indication function
Can retain the minimum pressure value displayed during measurement
Key-lock function (Selectable secret code)
The keyboard can be locked to prevent the accidental operation of the operation switch.
Zero-clear function
The pressure display can be set to zero when the pressure is open to the atmosphere.
Error indication function
This function displays the error location and content when a problem or error has occurred.
Anti-chattering function
Prevents possible malfunctions due to sudden fluctuations in the primary pressure by adjusting the delay time
Unit selection function
Can convert the display value
Power-saving mode
Reduces power consumption
Converts the display resolution from the normal value of 1/1000 to 1/100
Display resolution switch function
Can reduce flickering of the monitor
kPa ↔ MPa switch function
Copy function*1
Auto-shift function*1
Converts the unit between kPa and MPa
The settings of the master sensor can be copied to the slave sensors.
Measures the pressure at the time of external input and uses it as a reference to correct the set value of the switch

Set Pressure Range and Rated Pressure Range
Set the pressure within the rated pressure range.
The set pressure range is the range of pressure within which setting is possible.
The rated pressure range is the range of pressure that satisfies the specifications (accuracy, linearity, etc.) of the switch.
Although it is possible to set a value outside the rated pressure range, the specifications cannot be guaranteed even if the value stays within the set pressure range.

Over current
error
Load current of 80 mA or more is applied to the switch output.
Turn the power off and remove the

supply the power again.
Residual
pressure error
During zero-clear operation, pressure over ±7% F.S. (±3.5% F.S. for compound pressure) is
present. Note that the mode is returned to measurement mode automatically 1 second later.
The zero clear range varies by ±1% F.S. due to variation between individual products.
Perform zero-clear operation again
after restoring the applied pressure to
an atmospheric pressure condition.
Applied

Supply pressure exceeds the maximum set pressure
Supply pressure is below the minimum set pressure
Reset applied pressure to a level
within the set pressure range
System error
Internal data error
Turn the power off and then on
again. If the failure cannot be
solved, please contact SMC for
investigation.
Copy error
The copy function does not operate properly.
After clearing the error by pressing the
and
buttons simultaneously for a minimum of 1 second, check the wiring and the
model, and then attempt to copy again.
If the error cannot be reset after the above measures are taken, or errors other than those above are displayed, please contact SMC for investigation.

Function Details
G Anti-chattering function (Simple setting mode or F1)
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 by changing the delay time setting.
Available delay time settings
1.5 ms or less, 20 ms, 100 ms, 500 ms, 1000 ms, 2000 ms, 5000 ms
<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.

I Selection of power-saving mode (F80)
The power-saving mode can be selected.
With this function, if no buttons are pressed for 30 s, it shifts to power-saving mode.
At the time of shipment from the factory, the product is set to the normal mode (the power-saving mode is turned off).
(During power-saving mode, [ECo] will flash in the sub screen and the operation light will be ON (only when the switch is ON).)
J Setting of security code (F81)
The user can select whether a security code must be entered to release the key-lock function.
At the time of shipment from the factory, it is set such that a security code is not required.

manual for details about operation procedures and function codes.
The settings of the master sensor can be copied to the slave sensors,
reducing setting labor and minimizing the risk of setting mistakes.
The set value can be copied to up to 10 switches simultaneously.

ZSE20C(F)/ISE20C(H)
When there are large fluctuations in the supply pressure, the switch
may fail to operate correctly. The auto-shift function compensates for
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.

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*2 such

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 autoshift. 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.
