4. INSTALLATION
Unpacking
Carefully remove equipment from the carton and inspect the contents.
NOTE
– If any damage has occurred during shipment, notify the local
carrier at once. A report should also be forwarded to Simco-Ion, 2257 North
Penn Road, Hatfield PA 19440. See Section 9 (Warranty) for Return
Shipment information.
Determining Pinner Bar Location
Although Simco-Ion’s Pinner, Pinner-R and Pinner-T bars prevent hard arcs from
occurring, the bars do exhibit a soft arcing that can be both useful in setting up the
application and useful in keeping the system operational. As the distance between the
Pinner Bar and ground reference is decreased, the first signs of electrical stress will be
observed. The pins will start to display a purple glow and, in quiet surroundings, a
slight sizzling buzz may also be heard as air molecules become stressed. Continuous
operation in this condition will cause premature aging of the bar. Once the power
supply is in position and operational, ensure that there is no purple glow at the
emitter points. It is this purple glow that indicates the overstressed condition and
that the bar is not providing its maximum possible pinning voltage.
CAUTION
– FIRE HAZARD
Do not install or operate equipment in close proximity to any flammable
solvents or flammable materials.
Option 1: Charging Bar with a Grounded Surface
In
Figure 1
, the charging bar faces an empty core in
a roll-to-roll changeover application. The empty core
is mounted on a grounded metal shaft and a plastic
film travels between the charging bar and the empty
core. The negative ions created by the charging bar are
driven toward the grounded metal shaft by an electric
field formed between them. The film blocks ion travel
through the field and becomes electrostatically charged,
resulting in adhesion between the film and roll.
