D
Keylock function
The keylock function prevents operation errors such as the accidental changing of setting values.
This function displays error location and content when a problem or error has occurred.
E
Zero-clear function
This function clears and resets the zero value on the display of measured pressure.
The indicated value can be adjusted within
±
7% F.S. of the pressure at the time of factory shipment. (
±
3.5% F.S. for compound pressure)
A
Auto-preset function (F4)
The auto-preset function, when selected in the initial setting, calculates and stores the set value from the measured pressure. For example, if this function
is used for suction verification, 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. (This eliminates wide
variations of the indicated value.)
Suction Verification
Formula for Obtaining the Set Value
This function constantly detects and updates the maximum
(minimum) pressure when the power is supplied, and allows the
holding of the maximum (minimum) pressure value.
The hold value can be maintained even if the power supply is cut.
When the
buttons are simultaneously pressed for 1 second
or longer while “holding,” the hold value will be reset.

Description
Action
Over current
error
Load current of 20 mA or more is applied to the switch output
Turn the power off and remove the
cause of the over current. Then
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 the variation between individual products.
Use the zero-clear function again
after restoring the applied pressure to
atmospheric pressure.
Applied
pressure error
Supply pressure exceeds the maximum set pressure
Reset the applied pressure to a
level within the set pressure range.
Supply pressure is below the minimum set pressure
System error
Internal data error
Turn off the power supply and then
turn it on again. If the problem
cannot be solved, please contact
SMC.
If the error cannot be reset after the above measures are taken, or errors other than those above are displayed, please contact SMC.
