H
Anti-chattering function (F3)
A large bore cylinder or ejector consumes a large volume of air in operation and may ex-
perience 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.
If the switch will not recover to normal even after all of the above-mentioned solutions have been applied, consult SMC for investigation.

Solution
Load current of switch output (OUT1) exceeds 80 mA.
Shut off the power supply. After eliminating the out-
put factor that caused the excess current, turn the
power supply back on.
Bring the pressure back to within the set pressure
range.
Bring the pressure back to atmospheric pressure
and try using the zero-out function.
Load current of switch output (OUT2) exceeds 80 mA.
Supply pressure exceeds the maximum set pressure.
Supply pressure is below the minimum set pressure.
Internal data error
A pressure of
±
7% F.S. of atmospheric pressure is applied in the
zero-out function. (
±
3.5% F.S. or more for ZSE30AF (compound
pressure))
The switch will automatically return to measuring mode in 1 sec-
ond, however. Due to individual product differences, the setting
range of the zero-out function varies within
±
1% F.S.
Shut off the power supply. Turn the power supply
back on. If the switch will not recover to normal,
consult SMC for investigation.
J
Power-saving mode (F7)
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 pow-
er-saving mode.)
K
Secret code setting (F8)
It can be set whether code number input is required or not when
key is locked. It is set to input no code number when ex-factory.
