Setting Up Your Unit (continued)
Attach tag lines at several locations to help in controlling the unit when
lifted and to prevent spinning or swinging.
The dust collector should be lifted and lowered at a slow, uniform rate
and not allowed to bounce or joggle since this can cause excessive
impact stresses at the lift points.
Compressed Air Manifold: Typically, CAMCORP ships the compressed
air manifold installed complete with diaphragm valves and solenoid
enclosure(s), except when units are over legal shipping width with them
in place.
Doors and Flanges: Hold-downs on doors should only be hand
tightened. Excessive pressure can distort the door panel itself resulting
in leakage. All bolts on flanges should be tight. All ports in the dust
collector not being used must be plugged prior to start-up.
Electrical: A 120 volt 60 Hertz circuit is required to operate the dust
collector’s pulse-jet cleaning system (unless a different voltage for
components was requested). This timer must be wired according to the
wiring diagrams and be provided with a circuit that is free from transient
currents. The timer has a feature called “Demand Pulse” that allows the
output terminals to be energized and de-energized by the high and low
set points of a differential pressure switch such as a Dwyer Photohelic
Series 3000. The “Demand Pulse” terminals are marked “Pressure
Switch”. Do not over fuse.
The NCC pulse timer boards have adjustable pulse duration and interval
(time between valves firing) settings. Before applying power to the timer
always check these settings according to the table below. Since there are
many variances in operations and conditions these are presented only as
initial start-up guidelines. If you experience problems in cleaning of the
filter bags, please contact CAMCORP.
