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.

alarm history for your system using the buttons provided.
