CONNECTION
Take care that when using the products in series connection, the applied air pressuredrops
gradually unit by unit. (The volume of the drop depends on the connected tube length.)
Use the optional series connection set (ER-VWAR80) for series connection (One
●
set per unit is required). The maximum No. of the connectable units is 5 (Including
this unit). When using the units in series connection, fit the end connector on the
connector for series connection of the unit connected to the end. Even if only one
unit is used, fit the end connector on the connector for series connection.
Fit the air inlet fitting (enclosed with the series connection set) after taking the sealing
●
cap off with a hexagonal wrench. The tightening torque should be 0.5N･m or less.
Note that the gasket is fit in the air inlet. Be sure to tighten the fitting with the gasket.
When using the units in series connection, make sure that the air pressure around
●
the air inlet of each unit is appropriate.

INPUT SIGNAL CONDITIONS
● Conditions for the discharge halt input and the reset input are as follows.
・ Discharge halt input
Open
DSC OFF
(Low input)
Low
Note: Repeat control with 'DSC OFF' input should be 1Hz or less.
Note that the continuous discharge for 2 sec. or more is required for stable detection of check
output. (CHECK). In case of using with the continuous discharge for less than 2 sec. again
and again, confirm the check output (CHECK) with the continuous discharge for 2 sec. or
more when maintenance is carried out.

Notes: 1)
The air monitor function is to monitor the supplied air pressure. If the air pressure falls less
than 0.02MPa approx., the discharge from the needle stops and the indicator lights up. If
the air pressure rises again after the pressure fall was detected, discharge starts again.
2)
The air monitor function always check the air pressure and independent from the other functions
(ERROR, CHECK or the discharge halt input). Thus, even in the state that the discharge was
stopped by another function, if the air pressure falls, the air monitor indicator (orange) lights up.
3)
In the state that the discharge from the needle stops, such as when the air pressure fall is detected
or while the discharge halt input is input etc., CHECK and ERROR detection function do not operate.
4)
The discharge halt input is invalid in error state. CHECK function doesn't operate as well.
5)
When the discharge from the needle stops due to the air monitor function, the discharge
halt input or ERROR detection function, the detection result by CHECK function is erased.
The detection is carried out again when the discharge from the needle restarts.
6)
Remove the cause of error, and then reset the unit. In case the cause of error has not been
removed, the unit goes into the error state again.
7)
In order to reset the unit in error state, turn the power off and on again.
8)
In case the discharge from the needle is controlled in the state that air is supplied, CHECK
may be output temporarily due to a transitional state of the discharge phenomenon.
However, the charge removal capability remains the same.

MAINTENANCE
Make sure to turn off the applying air and the power supply while inspection,
●
cleaning or maintenance is carried out.
Before loosening the nozzles for maintenance etc., be sure to stop applying air.
●
Otherwise, the discharge needle unit may be flew by the air pressure.
If dirt, such as dust, etc., is stuck on and around the discharge needle or inside
●
the nozzle depending on the environment of use, the charge removal effect
deteriorates. Clean those areas periodically, as a reference, once a week.
However, when using this product in the environment exposed to too much dust,
be sure to clean up the discharge needle frequently.
The discharge needle is a part having a product life time. It is recommended that
●
the needle should be replaced, as a reference, after 10,000 hours in use. When
the needle is replaced, replace the discharge needle unit (optional).
Procedure for cleaning and replacing the discharge needle nit
Unscrew the discharge needle counterclockwise.
①
Remove dirt on and around the discharge needle, inside the
②
nozzle and inside the tube fit in the nozzle with a cotton bud
soaked in absolute alcohol. Particularly, clean inside the tube
fit inside the nozzle and around the discharge needle
thoroughly such that any dirt or grease doesn't remain there
(refer to the right figure), or the charge removal capability
may deteriorate. Remove / fit the discharge needle along the
guide groove on the air outlet of the main body.
After cleaning, screw the nozzle clockwise. Tighten the
③
nozzle by hand till it stops and then confirm that the nozzle
doesn't move. If the nozzle is not tightened enough, the
charge removal capability may deteriorate or the nozzle may
come off.
