Automatic cleaning with the timer
In addition to the pressure drop cleaning, preset cleaning times
can be established. These times will signal clean ing whether the
fans are in operation or not. This allows for off-line cleaning as
well as maintenance of filters dur ing low-airflow operation. When
there is low airflow (only one or two arms in operation), the
pressure drop will be naturally low, even though dust accumulates
on the sur face. When higher airflow is used (all five arms are in
use), this residual dust may cause a higher pressure drop and
result in an alarm condition. In applications where this variability
may happen, as well as cutting operations, timed cleaning is
recommended.
DO NOT USE THE TIMER CLEANING DURING THE FIRST TEN HOURS
OF OPERATION!!
This allows the precoating powder to get
established on the surface of the filter. If a cleaning cycle is
initiated during this initial period, the precoating powder may not
be well estab lished on the cartridge and will result in lower
efficiency and shorter life.
Timers can be set on the timer clock located in the con trol box.
The cleaning cycle will run continuously (factory set at one pulse
per minute) during the on time. The one minute interval can be
lengthened by adjusting the timer relay to the right of the clock
timer (off-time). One full revolution of the filters takes approx-
imately 60 pulses.
Adjusting the cleaning and pause time.
The cleaning and pause times for the pressure-drop activated
cleaning cycle are preprogrammed into the PC board software.
The times for the clock-timer operated cleaning, however, are
adjustable using the timer relay to the right of the clock timer. The
cleaning pulse time (upper dials) is pre-set to 1 second. This
should not be adjusted. The pause time has a minimum one
minute, but can be increased using the lower dials. For off-line
clean ing, longer pause times allow the fine dust to settle to the
drum.
Manual Cleaning
DO NOT INITIATE A CLEANING CYCLE DURING THE FIRST TEN
HOURS OF OPERATION!!
This allows the precoating powder to get
established on the surface of the filter. If a cleaning cycle is initiat -
ed during this initial period, the precoating powder may not be
well established on the cartridge and will result in lower efficiency
and shorter life.
A full cleaning cycle (one complete revolution around the filter)
can be initiated by pressing the start/reset button on the control
box. During this time, the cleaning pulse will fire, the tank will
refill during a pause time, then the next section of the filter will be
cleaned. This will continue until the complete filter has been
cleaned. During the entire revolution, the indicator will light
continuously. The cycle can be stopped at any time by pressing
the start/reset button.
