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 nonmetallic brush.
b) If acceptable performance is not restored, contact Simco-Ion Customer Service
at (215) 822-6401.
