The pulse cleaning settings can be adjusted by selecting the
Cleaning button on the Customer Settings screen. Figure 16
shows the Pulse Cleaning Settings screen. The cleaning modes
and various pulse settings can be updated on this screen.
Depending on the selections, items may appear or disappear
based upon their relevance.
The On-Demand cleaning mode is the more desirable of
the two modes. This mode will allow the PNP to monitor
the performance of the primary filter. When the primary filter
reaches the high set point the cleaning system will activate
automatically and pulse each filter one at a time until the
low set point is reached. The program will remember the last
filter pulsed and start the next cycle when the high set point
is reached again. This will give the filters the best cleaning
performance possible. The high factory default setting will
be 2.25, and the low value will be 2.00. As the primary filters
age the high and low set points will need to be adjusted
over time by the operator to give the primary filters the best
performance.
The Continuous cleaning mode is only desirable when the
process dust is very heavy and will plug the primary filters often.
With this mode of cleaning the pulse valves will continuously
fire as long as the blower is in operation.
The last mode is Down-Time cleaning. This cleaning mode
can be used in conjunction with all previous modes.
The selection of this mode is for cleaning the filters after the
blower is turned OFF. The unit will wait until the blower is
turned off and then delay the amount of the setting of the
Pulse Delay. The Pulse Delay is set to 10 seconds from the
factory. It will then pulse each filter for cleaning. The number
of cycles is selectable by the operator, but is set to 2 as
default. Down-Time Cleaning is factory set to ON, but if no
Down-Time cleaning is desired then select the number of
cycles at 0.
The Pulse Delay is the amount of time in seconds between
the pulsing of each valve. If your compressed air system is
not able to completely fill the air tank built into the PNP fully
before the next pulse, then the operator will need to increase
the delay time between each pulse.
The operator can select the Service settings shown here.
Each of the selection will allow the operator to see the health
of the unit.
The Service hours will allow the operator to see how long
the Primary filter and the after filter have been in service.
These hours are reset table by holding touching the specific
button and holding it until the number resets to 0.
The operator can also see the total number of hours the
PNP has been in service since being built at the factory.
During factory testing the units are quality checked and may
show a low amount of hours such as 1 or 2 from this test.
