IQ Power HLC Power Supply
& Control Station
5201259 Rev. D
System Operation
The operation of the IQ Power HLC Power Supply is controlled through the IQ
Power Control Station. In operation, a device icon appears on the Control Station
Home Page. Tapping on the device icon opens a Summary page containing
information about the HLC power supply, static neutralizing bar, and static sensor
(if connected). More detailed information and user editable parameters are available
through device tabs.
There are four Operation Modes available for the IQ Power Neutralizing Bar: Fixed,
Auto-Tune, CLFB and Manual. The Operation Mode is found on the Control
Station, HL Device page, Neutralizer tab. By tapping on the pencil icon adjustment
may be made to the Operation Mode.
Fixed
is the default setting and requires no user input. Fixed provides standard
operation, with output voltage regulation. The output current is monitored (against
a calibration point) and when output current is outside acceptable limits a clean bar
alarm will occur.
Auto-Tune
is an operation mode that includes the current monitoring found in the
standard mode, plus automatic output compensation that takes into account web
speed, bar type, bar mounting distance and measured ion current to optimize static
neutralization performance. In order to successfully invoke Auto-Tune, certain
operating parameters must be defined:
• The Web Speed will have to be entered by the user.
• The Mounting Distance will have to be entered by user. It is the distance
between face of bar and the web or material to be neutralized.
CLFB (Closed-Loop Feedback)
is an operation mode that incorporates use of an
IQ Power HL Sensor. The sensor must be mounted downstream (after, minimum
12”) the static bar so that it can “report back” to the static bar on how well it’s
performing. The Sensor Interface must be paired with the HLC. Once CLFB is
enabled and the bar is paired with the sensor, the sensor detects any electrostatic
charge on the web and directs the static bar to adjust its ion output to minimize any
residual charge on the web. For best performance, the static bar should be mounted
as close as possible (within the operating distance range) to the web. This allows the
static bar to use its maximum range of performance while still achieving a minimum
of residual charge.
Manual is a power unit mode that includes the voltage regulation and current
monitoring found in the standard mode, plus manual control of the ion balance
ratio. This mode of operation would only be selected where the web, or material to
be neutralized, exhibits extreme and consistent charging of one polarity.
