ePad Automatic Pulse Controller
The DFS Series Collectors come equipped with the RoboVent ePad controls, which includes
automatic control of all pulse cleaning functions. The Controller constantly measures the
pressure across the filter surface and provides a display in both kilopascals (kPa) and inches
of Water (in. WC). This Pressure Differential value shows the pressure drop across the filters,
helping to gauge filter life. Once the pressure across the filter has risen by a pre-set factor,
the self-cleaning system will begin to operate. (see
APPENDIX A
).
On-Line Cleaning vs Off-Line Cleaning
The On-Line Cleaning Cycle pulses the equipment while it is running by a pre-set time
programmed into the controller. (see
APPENDIX A
). The on-line default setting is 90 seconds.
Once the differential pressure between the clean and dirty sides of the filters has reached a
pre-determined pressure, a signal will be sent to one of the pressure valves and compressed
air will back-flush that line of cartridges. This helps keep the dust loose so that the off-line
cleaning can remove the dust from the filter.
Off-line cleaning happens automatically every time the system is shut down. This is the most
effective means of removing the dust from the filters. The duration and frequency of this
cleaning cycle is programmed into the controller. (see
APPENDIX A
).
IMPORTANT!
The off-line cleaning cycle is extremely important for extended filter life! Therefore,
it is important that power to the ePad Controller is not disconnected via the main
disconnect switch on the control panel. The DFS should be powered on via the ePad
touch screen. Turn off the main disconnect only when servicing the unit.
A record of this pressure differential should be recorded periodically and kept for future
reference. During use of your DFS the differential pressure will increase as the filters load
up. (Cartridge filters should be replaced when the gauge reads approximately 2.7 kPa. to 3.4
kPa.) To change cartridges follow the procedure for “
Cartridge Filter Maintenance
”.
Note: 1 kPa is equivalent to approximately 4 inches of water gauge.
