Description
1
ALARM
Output
Output abnormality (refer to "8. Troubleshooting" for details)
2
CHECK
Output
Ionizer discharge abnormality (1 shot pulse of 200 ms is output at abnormality)
3
MAINT
Output
Maintenance output (air valve for blow/ionizer discharge needle)
4
EPS
Output
Electrostatic potential sensor decision output (output when the output is below the setting
value)
5
DUST
Output
Dust sensor decision output (output when the output is below the setting value)
6
END
Output
Blow operation finish output (1 shot pulse of 200 ms is output when the operation finishes)
7
VAC_START
Output
External device operation output
8
STOP
Input
Operation stop input
9
START
Input
Operation start input
10
ZC
(Zero
calibration)
Input
Electrostatic potential sensor zero calibration input
This is a feature to calibrate the reference potential where the measured value equals to 0 V.
0 V potential is read while facing to the grounded metal plate or a space without charged
objects.
11
DC24 V
-
Power DC 24 V output
It is connected to the 24 V power of, for example, an external sensor. (Capacity 24 V/100 m A
Max)
12
0V
-
I/O 0 V (common to the power connector 0 V)
Note: 0 V and FG (ground terminal) are internally connected.
Note: Value of the dust sensor is just a guide. It does not guarantee removal of dust from the workpiece.
