Set-Up and Operation
The ESD ProCenter Plus is shipped set-up and ready to use. The installation, set-up and use procedures are the same
as a standard ProCenter Plus. See the Set-up guide that is included with the ProCenter Plus.
There are two settings to the ESD system which are optimized at the factory and require no additional adjustment.
1.
The air flow out of the ionizer electro probe's sockets. This air flow is adjusted with the center regulator in
the electronics box on the back of the ProCenter. This air flow is set at the factory using an electrostatic
meter charged plate system to measure static neutralization in the work area of the chamber. The air flow
requires no further adjustment.
2.
The angle of the ionizer bar. The ionizer's angle is set at the factory to flood the normal working area of
the blasting cabinet. As with the ionizer's air flow, no further adjustment is required.
GUIDELINES FOR USING THE ESD CONTROL PROCENTER:
1.
Only blast when the ProCenter is operating and air is flowing out through the electrode probes.
2.
Check to be sure the ionizer is ON and operating correctly. The indicator light in the top of the bar should
be green. If the light is red or flashing there is a problem with the system and maintenance is required.
(See below)
3.
Ground as many of the board's connectors as possible.
4.
If possible, use an abrasive that produces low charging.
5.
The use of operator grounding devices is highly recommended.
6.
Observe good board handling procedures both in and out of the ProCenter.
MAINTENANCE:
Note: Prior to performing any maintenance on the ProCenter Plus, always turn off unit and disconnect it from its electrical
power and compressed air sources.
The ionizer bar has a series of indicator lights on its top surface.
ION MONITOR: When the ProCenter Plus is first turned on, the ION MONITOR lights will sequence through
a series of red flashes and then the center light will remain on in a steady green state.
ION/ALM COND:
Flashes 1 time per second – Indicates environmental conditions (e.g. the temperature, humidity or metals in
or near the Procenter Plus) are unstable and likely to reduce the performance of static elimination. This
condition could likely be caused by metal object such as a fixture inside the cabinet which is absorbing the ions.
The ionizer will continue to operate but the static elimination will likely be unstable.
Flashes 2 times per second – Indicates the level of ion generation is low due to dirty or worn out electrode
probes. Clean or replace probes. (See below) The ionizer will continue to operate but at diminished
effectiveness.
Flashes 3 time per second – Indicates internal circuit is damaged or an abnormal electrical discharge occurs.
The ionizer will stop emitting ions and needs to be repaired or replaced.
Electrode Probe Maintenance:
Some abrasives may cause contamination of the electrode probes. They can be cleaned with a soft brush or cotton swab
with alcohol, and also by gently blowing off with compressed air. If the probes lose their sharp point, they should be
replaced. The probes can be removed for replacement by unscrewing counter clockwise. A package of (4) Electrode
Probes is Comco part number ST2472.
