Contracor ECO-80SL [31/152] Troubleshooting

CONTRACOR

ECO-series suction blast cabinets

whichever comes rst. Only at that point should the dust collector lter be cleaned by opening

and closing the ball valve rapidly several times, thereby expanding a pulse of compressed air

onto the inner surface of the lter.

When tted with an automatic pulsed air cleaned dust collector, reduce the pressure

of the pulse regulator to 0 bar (see section 4.3.6). The timer will continue to pulse, but as the

pulse pressure is null, no cleaning of the lter will occur. Operate the cabinet without pulsing

for about two hours, or until visibility decreases, which ever comes rst. At that point turn the

pulse regulator to 4,5 bar, to start the normal 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 lter cartridge. Empty the dust container

regularly. Inspect and replace the cartridge if necessary. It is imperative that the dust collector

lter be regularly cleaned (see section 4.2.4).

6.1.2 Fan 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 ne or worn

out can increase dust quantity and thus cause poor visibility.

6.1.4 Throttle valve for air suction closed too far, restricting air ow in cabinet. Adjust
