5.2.7 Filter cartridge seasoning
New cartridges must be seasoned. Cartridges are seasoned by letting a dust cake develop
on the filter media before starting the pulsing cycles. To stop the pulse, turn the pulse regulator
off (to 0 bar). Operate the cabinet without pulsing for about two hours, or until visibility decreases,
which ever comes first. At that point turn the pulse regulator to 4,5 bar, to start the pulsing cycle.
6. Troubleshooting
ATTENTION!
To avoid serious injury, observe the following when troubleshooting.
. Turn off the air, and lock out and tag out the air supply.
. If checking the controls requires air, always enlist the aid of another person to:
- Hold the nozzle securely.
- Operate the foot pedal.
. Never bypass the foot pedal or wedge it in the operating position.
. Never override the door interlock system.
6.1. Poor visibility.
6.1.1
Poor visibility may be due to dirty filter cartridge. Empty the dust container
regularly. Inspect and replace the cartridge if necessary.
6.1.2
Motor rotating backwards. The motor should rotate as indicated by the arrow on
the housing. If it does not rotate in the proper direction, lockout and tag-out the power supply
and switch the motor leads as shown on the motor plate
.
6.1.3
Using soft media that rapidly breaks down, or using media that is too fine or worn
out can cause poor visibility.
6.1.4
Outlet damper closed too far restricting air flow in cabinet. Adjust static pressure
per Section 4.3.5.
6.1.5
Inlet damper requires opening. Restrictions at the inlet damper reduces air
movement in the cabinet. Open damper per Section 4.3.5.
6.1.6
Hole worn in flex hose between cabinet hopper and reclaimer inlet, or reclaimer outlet
and dust collector inlet. Replace hose and route it with as few bends as possible to prevent wear.
