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.
<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.
H
Unit selection function (F0)
Display units can be switched with this function.
∗
The ZSE20 (vacuum pressure) and ZSE20F (compound pressure) will have different setting and display resolution when
the unit is set to MPa.
I
Power 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.
(During power saving mode, [ECo] will fl ash in the sub screen and the operation light is ON (only when the switch is ON).)
J
Setting 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.
Available delay time settings
1.5 ms or less, 20 ms, 100 ms, 500 ms, 1000 ms, 2000 ms, 5000 ms
