Function Details

the set pressure value may change ±1 digit.

E
Key lock function
This function prevents incorrect operations such as accidentally
changing the set-value.
F
Zero-clear function
This function clears and resets the zero value on the display of mea-
sured pressure.
For the pressure switch with analogue output, the analogue output
shifts according to the indication. A displayed value can be adjusted
within ±7% F.S. of the pressure when ex-factory. (ZSE10F (for
compound pressure) ±3.5% F.S.)
B
Auto-preset function (F 5)
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.
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.)

Formula for Obtaining the Set-Value
A
Copy function (F97)
The settings of the master pressure switch can be copied to the slave pressure switches.
This can reduce the labour for setting and prevent the entry of incorrect set-values.
The set-value can be copied to up to 10 switches simultaneously.
(Maximum communication distance 4 m)
1) Connect the power supply and copy line as shown in the
left figure.
2) Select the slave switch which is to be the master, and
change it into a master using the buttons. (In the default
setting, all switches are set as slaves.)
3) Press the button of the master switch to start copying.
This function constantly detects and updates the maximum (mini-
mum) 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.

Anti-chattering function (F 3)
A large bore cylinder or ejector consumes a large volume of air in operation and may expe-
rience 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.

Display unit switching function (F 0)
Display units can be switched with this function.

Remedy
Load current of switch output (OUT1) exceeds 80 mA.
Turn the power off and remove the output factor for
the over current. Then turn the power on.
Reset applied pressure to a level within the set
pressure range.
Perform zero-clear operation again after restoring
the applied pressure to an atmospheric pressure
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
During zero-clear operation, pressure over ±7% F.S. is applied.
(ZSE10F (compound) ±3.5% F.S.)
After 1 s, the mode will reset to measurement mode. ±1% F.S. of
the zero-clear range varies between individual products.
Turn the power off and turn it on again. If the failure
cannot be solved, ask SMC for repair.
J
Power-saving mode (F80)
Power-saving mode can be selected.
It shifts to the power-saving mode without button operation for 30 se-

when ex-factory. (Decimal points and operation indicator light (only
when the switch output is turned ON.) blink in the power-saving mo-
de.)
K
Secret code setting (F81)
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.
The F in ( ) shows the function code number. Refer to the Operation
Manual for the details of operation procedures and function codes.
