The grills below each fan function as
sensors and feed back a signal to the
balance circuitry. Therefore, it is
important not to hang or attach anything
to the fan grills.
Controls and Functions
Figure 2. Control Panel
The
CONTROL PANEL
is located on
the right hand end of the ioniser. It
provides controls for fan speed,
balance, and a key switch to prevent
unauthorised adjustment of the controls.
Also located on the control panel is an
I/O port that may be used for auto
calibration (with optional accessory
cable). It also is used to provide output
signals to allow remote monitoring of
ioniser status.
A. OFF/SET/LOCK
key switch - this
switch controls the power to the ioniser.
When the SET position is selected, it
allows the balance and fan speed to be
adjusted. When the LOCK position is
selected, a LOCK indicator is
illuminated on the front panel of the
ioniser. In this position, the balance and
fan speed controls are disabled and the
key is removable. In the OFF position,
power is shut off to the ioniser and the
key is removable.
B. FAN
speed adjustment switches are
used to set the fan speed to the desired
level that provides the best performance
while minimizing operator discomfort.
With the key switch in the SET position,
pressing and holding the “+” symbol will
increase fan speed, and the “-” symbol
will decrease fan speed. Relative fan
speed is displayed on the front panel
indicator.
C. BAL
controls are used to adjust the
balance of the ioniser and are used in
conjunction with a charged plate
monitor. With a charged plate located
directly under the ioniser, pressing the
“+” symbol will shift the balance offset
positive, while pressing the “-” symbol
will shift it negative. The BAL controls,
like the FAN speed, are only adjustable
when the key switch is in the SET
position.
D. I/O PORT
serves a dual purpose. It
accepts signals from a charged plate
monitor and automatically calibrates the
ioniser when the key switch is in the
SET position. It also outputs ioniser
status signals that can be useful for
remote monitoring.
E. IEC INPUT CONNECTOR,
based on
the International IEC 60320 Standard,
allows the power to be disconnected at
the ioniser and provides a fuse drawer
for a 5mm x 20mm fuse. The fuse
drawer may be opened when the
cordset is removed. In addition, an IEC
Outlet on the opposite end of the ioniser
can supply power for a charged plate
monitor, or for up to 10 ionisers to be
daisy-chained together.
Front Panel Display and
Controls
See Figure 3.
System Status
is the information center
on the front of the ioniser. From it, the
operator can easily check the
operational status of the ioniser.
F. PWR
- this indicator will normally be
green when the ioniser is operating
correctly. When the autobalance circuit
can no longer adjust for dirty emitter
pins, this indicator will turn red and
begin to flash. It is normal for it to flash
for a few seconds each time the ioniser
is turned on. This indicator will be on
when the key switch is either in the
"SET" or "LOCK" position.
G. LOCK
- when the key switch on the
end of the ioniser is set to lock, this
indicator will display a distinctive blue
light. This makes it readily apparent
that the ioniser has its settings locked,
preventing unauthorized adjustment.
H. AIRFLOW
- this display indicates
relative airflow output from the fans. If
the key switch is in the "SET" position
and the "+" or "-" button are pressed
and held, the fan speed will increase or
decrease with a corresponding change
in the AIRFLOW display. As fan speed
is increased, the display will move to the
right.
Minor Adjustments
(see figure 4) are
provided for balancing each fan zone.
These adjustments are designed for
minor adjustments to balance one fan to
another. Overall balance adjustments
should be done with the "BAL" switches
on the end panel.
VR6, VR5, VR2, and VR1
- are the
zone balance adjustments for the zones
1 through 4 respectively. Zone 1 is
closest to the right end. 61cm models
will only have VR6 and VR5
adjustments. These adjustments are
covered in the section titled "Calibration
Instructions".
VR3 and VR4
- are adjustments to
center the alarm and to change the
alarm sensitivity. These adjustments are
covered in the section titled "Calibration
Instructions".
