Troubleshooting Electrical Stress
• Electrical stress can occur between the bar and a ground reference beneath
the target material. This stress typically occurs at edges of material being
charged and comes from the ion emitter points at the end of the Charging Bar.
Eliminate this stress by gradually reducing the operating voltage from the power
supply.
Troubleshooting Electrical Arcing
• If electrical stress occurs between the bar and frame member on which the bar
is mounted, the bar may be improperly mounted. Verify that all equipment has
been properly mounted and grounded.
• If electrical stress occurs from the end of the bar to the side frame of the
machine, slide the bar away from the side frame if possible. If it is not possible
to do this, it may be necessary to install an arc shield, please call your Simco-Ion
representative for more details.
Troubleshooting Low Pinning Strength
• If pinning strength is not adequate and the power supply is already at maximum
output voltage, moving the bar closer to the target material can increase
pinning strength. Reduce the bar-to-material distance until pinning strength
is adequate. At this new distance, it may be necessary to adjust the operating
voltage of the power supply.
• Low pinning strength may also be due to erosion of the emitter points. Sharp
points promote the best ionization of air molecules. Inspect the emitter points,
if they are visibly eroded or corroded follow these steps:
a) Remove contamination by brushing the emitter pins with a non-metallic
brush.
b) If acceptable performance is not restored after cleaning, the pins of the
Pinner-R Bar should be replaced (NOTE- Emitter pins of the Pinner and
Pinner-T Bar are NOT replaceable). Remove existing emitter pins using
needle-nose pliers and replace with new pins in each socket.
c) If acceptable performance is not restored, contact Simco-Ion Customer
Service at (215) 822-6401.
