The interlocks should stop the blasting when the doors are opened, and permit blasting
when the doors are closed.
NOTE:
Negative pressure inside the cabinet may cause the doors to flex inward. Tests
should be performed with the exhauster on.
4.3.7 Pulse pressure
Adjust pulse pressure using the regulator mounted on the pulse manifold. Begin pulse
pressure setting at 4,5 bar.
When pulsing alone does not adequately clean the cartridge, increase pulse pressure
by 0,5 bar increments up to max. 6,0 bar. Increasing pulse pressure over 6,0 bar may cause
damaging of the cartridge filter. If after pressure increasing, dust cakes on the cartridges
and differential pressure increase, adjust cycling of the pulses.
4.3.8 Timer
Adjust pulse time and cycling on the timer
(see Picture 2 for location).
Use ON scale to adjust the pulse length and
OFF scale to adjust the time period between the
pulses.
Begin setting is as follows:
Pulse length
(ON scale) - 60 ms (by 4.5 bar
pulse pressure).
Time between pulses
(OFF scale) - 5 min
