Remarks
Range: 0.1–2 nS
Set the value lower to increase sensitivity and to deactivate the
electrostatics sooner as a grounded object approaches the applicator. Set
the value higher to decrease sensitivity and to eliminate nuisance errors.
This value is most useful for slow-moving targets.
Range: 0.1–4 nS/s
Set the value lower to increase sensitivity and to deactivate the
electrostatics sooner if a grounded object is approaching the applicator
at too high a speed. Set the value higher to decrease sensitivity and to
eliminate nuisance errors.
Range: 0–100kV (solventborne) or 0–60kV (waterborne)
Decrease the voltage if changes to the static and dynamic limits are not
sensitive enough.
Range: 0.01–1.00 s by 0.01
Valid for all Presets. Set the averaging interval to make the Dynamic Arc
Limit more sensitive. Lowering this setting adds to the sensitivity achieved
by setting the Dynamic Arc Limit itself. The default averaging threshold
is adequate for most applications. If nuisance errors are seen when
triggering or detriggering fluid, increase this parameter.
Range: 0.0–30.0 s by 0.1
Valid for all Presets. Arc detection is suppressed from when electrostatics
are activated until the blanking time has elapsed. Adjust the setting to
ensure the system reaches full voltage during the blanking time. If arc
detection errors occur when the electrostatics are activated, increase the
blanking time. Decrease the blanking time for greater sensitivity.
Arc detection is deactivated during the blanking time.
• Activate the electrostatics only when the applicator is in SAFE
POSITION.
• Do not move the applicator out of the SAFE POSITION before the
blanking time has elapsed and arc detection is active.
Use interlocking signals between the controller and the device performing
the applicator's motion control. See
information.
Range: 0.0–5.0 s by 0.1
Valid for all Presets. Increase the transition time if arc detection errors
occur when the voltage (or current) set point is changed. This setting helps
eliminate nuisance arc detection errors during transition time.
