One-Point Ionizer with S Power Supply
Checking for Proper Operation
When the one-point ionizer had been connected to the power supply using the high voltage
cable, turn the power supply ON. Then use Simco-Ion’s voltage detector to check for
proper functioning of the emitter point and high voltage supply. Place the voltage detector
tip on the one-point ionizer’s emitter point. The voltage detector’s top will be illuminated
to indicate proper functioning of the emitter point.
3. MAINTENANCE
Turn equipment OFF before cleaning, removing ionizers from machine, or breaking any
ground connection. If metal filings or fragments fall into the tip of the ionizer, they are apt
to short circuit the unit and make it inoperative until the particles are removed. Loosen the
ionizer brackets and rotate the unit to face downward, tapping it to dislodge the particles.
Rotate the ionizer back into position and tighten the brackets. Compressed air may be
used to keep the inside of the ionizer clean. Periodic use of a soft brush or compressed air
will prevent the points from accumulating hardened balls of lint, grease, and other foreign
matter that reduce their sharpness and decrease efficiency. One easy way to remove built-
up deposits is to occasionally press a soft pencil eraser down over each point in turn and
twist slightly. Including the one-point ionizers in the regular procedure of cleaning the
machine will pay dividends in service and excellence of performance.
4. TROUBLESHOOTING
If equipment fails to function properly, check connections to be sure they are tight before
proceeding with the following tests.
NOTE
– When the one-point ionizer is operating properly, no visual arcing should
occur. If the ionizer should arc constantly, check this particular unit for metal
fragments or other contamination that should be removed as outlined under
Maintenance above. When the voltage detector produces no light, the trouble is
either a defective ionizer or defective power supply.
To locate the faulty equipment:
1. Turn OFF current to power supply.
2. Disconnect all ionizers from the power supply by unscrewing knurled plugs from
plastic receptacles and pulling out high voltage cables.
3. After all ionizers have been unplugged, turn ON current to power supply and attach
a piece of insulated wire or cable to the ground terminal on the power supply.
4. Insert the other end of the wire into one of the plastic receptacles. As the conductor
approaches the screw at the back of the exposed hole, a spark should occur.
