Function Details
G Anti-chattering function (Simple setting mode or F1)
A large bore cylinder or ejector consumes a large volume of air during operation and may experience a temporary drop in the supply pressure.
This function prevents the detection of such temporary drops in the supply pressure as errors 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.
H Unit selection function (F0)
Display units can be switched with this function.

Additional range
I
Input range selection (F0)
Display value can be set by user according to the sensor
input (voltage input: 1 to 5 V, current input: 4 to 20 mA).
∗ The display and analogue output are interlocked, so if one is changed
the other will change.
J
Power-saving mode (F80)
Power-saving mode can be selected.
It shifts to power-saving mode automatically when there is no button operation for 30 seconds.
The product is set to normal mode (Power-saving mode is OFF) at the time of factory shipment.
(When in power-saving mode, [ECo] will fl ash in the sub screen and the operation light will be ON (only when the switch is ON).)
K
Setting of security code (F81)
Users can select whether a security code must be entered to release the key lock.
At the time of factory shipment, it is set so that a security code is not required.
