6. TROUBLESHOOTING
NOTE –
Only qualified service personnel are to perform troubleshooting tasks.
1. Troubleshooting electrical stress observed between Charging Bar and the target
material:
• 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.
2. Troubleshooting electrical arcing from Charging Bar to machine frame:
• 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
representative for more details.
3. 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.
NOTE –
Do not exceed the 5.0 mA current capacity 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:
• Remove contamination by brushing the emitter pins with a nonmetallic brush.
• If acceptable performance is not restored after cleaning, the pins of the Pinner
Superbar should be replaced. Remove existing emitter pins using needle-nose
pliers and replace with new pins in each socket.
• If acceptable performance is not restored, contact Simco-Ion Customer Service at
(215) 822-6401.
