Manual No. 23478 Rev D
Use conditioner proportionately for larger collectors.
* It does not impair cartridge efficiency by adding
additional conditioner. Once the container is open, use
all the conditioner rather than store an opened container.
6.2.3.3
Start the exhauster and feed the conditioner up
stream of the collector into the ventilation system, such
as ducting access port, blast room outlet baffle or
reclaimer inlet or access door. Feed the conditioner slow
enough so it does not fall out of the air stream at the
intake point.
NOTICE
Do NOT shut OFF the exhauster for six hours
after the treatment or the conditioner may
dislodge from the cartridge media.
6.2.3.4
Reset the damper to 100% open if the collector
is new or to the original setting if replacing cartridges.
6.2.3.5
Begin operation of the system
but do NOT turn
the sequence switch ON until the differential-
pressure gauge reads is 2" above the initial reading
,
after the exhauster is adjusted to the correct cfm as noted
in Section 4.3 or 4.4. After the 2" difference in pressure is
reached, turn the sequence switch ON to start the pulse
cycle.
6.2.4
Set Pulse Sequence Timer
6.2.4.1
After the differential pressure is reached, set the
pulse pressure to 70 psi per Section 4.1, and set the
timer OFF time to 40 seconds per Section 4.2.
7.0 TROUBLESHOOTING
WARNING
Shut down the collector immediately when dust
emits from the exhauster. Check to make sure
filters are correctly seated and not worn or
damaged. Prolonged breathing of abrasive dust
and blasting by-product dust could result in
serious lung disease or death. Short term
ingestion of toxic dust such as lead, poses an
immediate danger to health. Identify all
materials that are to be removed by blasting,
and obtain a Safety Data Sheet (SDS for the
blast media
.
7.1
Collector not pulsing
7.1.1
Check the manifold-pressure gauge. If pressure
is low, check the compressed-air supply; look for a
closed supply valve.
7.1.2
Check function of the pressure regulator located
on the pulse-manifold inlet.
7.1.3
Make sure the sequence switch located on the
panel cover is ON.
7.1.4
Check the fuse in the sequence control panel.
Replace as necessary.
7.1.5
Have a qualified electrician check for electrical
malfunction; check the supply voltage to pulse sequence
board. Check outlet voltage to solenoids.
7.2
Some cartridges not pulsing
7.2.1
Solenoid defective. Have a qualified electrician
check supply voltage to solenoids.
7.2.2
Check the diaphragm pulse valves.
7.2.3
Check for blockage in the tubing between the
diaphragm pulse valve and solenoid assembly.
7.3
Pulse is a steady stream of air instead of a
quick pulse
7.3.1
Check for a leak or split in the tubing between
the diaphragm pulse valve and solenoid assembly.
7.3.2
Solenoid remaining in open position. Have a
qualified electrician check for electrical malfunction, clean,
or replace.
