4.3.3 Basic Screens
Filter Screen
The Filter screen can be displayed by the operator by
selecting the filter status icon on the Home screen shown
in Figure 6. The Filter screen will then be displayed with
all available filters. This screen will display the differential
pressure across the filter during operation.
Blower Screen
The standard blower screen will display the status of the
blower. If your equipment is equipped with the Auto-Flow
option and it is activated, the Blower screen will look
different than that shown in Figure 8. Refer to section 4.3.4
for additional details. The only time the blower will shut
down is when the blower has an internal fault. Such faults
as: Low line voltage, phase to phase issues, ground issues,
temperature issues, or for a catastrophic failure. If the
blower shuts down refer to Section 6 for troubleshooting.
On the blower screen you are able to adjust the speed
of the blower using one of two different ways. The first
adjustment can be done using the up/down arrows.
This adjustment will achieve a change of +/- 1%.
This will increase or decrease the airflow adjustment
by 1% for each touch of the up or down arrows.
The second method of airflow adjustment is to touch the
box that shows the percentage of the airflow. A number
pad will be shown in a pop up screen. You can enter any
number between 20 and 100 this will correspond to the
percentage of blower capability. The blower is capable of
4,200 RPM at 100%, 3150 RPM for 75%, 2100 RPM for
50%, and 1050 RPM for 20%. These numbers are only an
approximate of the actual that could be displayed.
There is a minimum set point for speed which is 20%
for the purposes of the blower design. The PNP may
have multiple blowers incorporated within the system for
the designed performance of the unit depending on the
customer application. All of these blowers will respond as
one blower with our controller.
Cleaning Screen
The cleaning screen will show the current settings of the
cleaning system as well as current operating values related
to the cleaning system. To make adjustments to the
cleaning system, refer to section 4.3.6.
Information Screen
The information screen will provide a phone number for
customer service. There is also a link to our website that
can be used to locate your nearest representative.
You are also able to see any pending alarms and the
alarm history for your system using the buttons provided.
