Thin Type Ionizer
ER-VW
Air supply monitoring function
This function causes discharging to stop automatically if the
supply of air drops below a certain pressure. Notification of
this is given when the AIR indicator lights and the discharge
output (DSC) turns off. This prevents objects which are not
charged from being overlooked when the air supply has
been stopped.
FUNCTIONS
The functions support accurate charge removal
In addition to the air supply monitoring function, the
ER-VW
is equipped with the following functions to ensure accurate
charge removal.
•
Discharge halt function
•Check function
•
Abnormal discharge
monitoring function
•
Discharge output
•Check output
•
Error output
: Uses external input to forcibly stop discharge.
:
Uses the CHECK indicator and output to notify the operator
when it is time to clean or replace the discharge needle.
: Uses the ERROR indicator and output to notify the
operator when a problem with discharge occurs, and stops
discharge. It can be canceled by means of reset input.
: Output is ON during discharging. This lets you
check when discharging is being carried out.
: Output turns ON when the discharge needle is dirty.
: Output turns OFF when there is a problem with
discharging (normally it is ON). It also allows you to
check the power supply to the ionizer.
