5.8.3
As the filter cartridge cakes with dust, differential
pressure increases, and the pulse-pressure setting may
not adequately clean the cartridge (does not reduce
differential pressure below 4" WC, as noted on the
differential-pressure gauge). When differential pressure
reaches 4” WC, increase pulse pressure by increments
of 10 psi, up to the maximum of 100 psi.
5.8.4
When the maximum pulse pressure of 100 psi is
reached and pulsing does not lower differential pressure
below the changeover pressure of 4" WC, decrease
pulse OFF time to 20 seconds, per Section 5.9.2.
5.8.5
When differential pressure stays above 4" WC.
after increasing pulse pressure to 100 psi and
decreasing OFF time to 20 seconds, replace the
cartridge, per Section 7.12.

Digital Pulse-Control Timer
The pulse timer is attached to the diaphragm pulse valve
located on the dust collector pulse reservoir as shown in
Figure 21.

NOTE: There is no need to set the timer functions or
subranges.
If the timer function is accidentally changed, refer to
Section 5.9.4 to reset it to Function "A".
If timer subranges are accidentally changed, refer to
Section 5.9.5 to reset them to factory settings.

FACTORY SETTINGS

5.9.1.2
The timer is factory set at 40 seconds OFF and
150 milliseconds (0.15 second) ON, as shown in Figure 22.
Every 40 seconds, the cartridge is pulsed for 0.15 second.
5.9.2
Setting pulse OFF time (time between each
pulse) ‒ Figure 23
NOTE: The numbers shown in Figure 23 signify the
following step numbers:
1. Make sure the OFF subrange is set to seconds. The
sec (seconds) indicator light should be lit, as shown in
Figure 23. If the subrange is other than seconds,
reset it as noted in Section 5.9.5.1.
