Feedback
The addition of a Meech 988 Feedback sensor bar can greatly increase the accuracy
of the neutralisation of static charges. By providing closed-loop control of the 977CM
the residual static charges on materials can be minimised despite changing conditions
and machine running speeds. This is particularly useful on rewinds, where large
charges can build up if the ionising system is not adjusted correctly. The feedback
system is primarily intended for use on installations using Meech model 971 Pulsed
DC Ionising bars.
In normal operation, the 977CM operates at a fixed rate and balance. The frequency
is set dependent on the distance from the ionising bar to the target material. Using
a static locator (983v2) the charge on the material after it has passed the ionising
bar can be measured. Ideally, the Ion balance of the output can be adjusted by the
operator, to remove all the charge on the material.
In reality, changes in running conditions, materials and cleanliness of the bar means
that this ideal state cannot be reached without constant adjustment of the pulsed DC
controller.
