MODEL PL PLATE COIL
Plate coils can either be mounted under a previously
prepared metal free section such as wood or fiberglass
or if the plate coil is a SF or SFC type item directly
mounted onto the base of a metal-sided conveyor.
In the latter case if the base of the conveyor is metal,
a section of it must be removed for the length of the
coil plus 1/8" (3mm). The search coil can be drilled into
or through in any of the crossed areas shown on the
drawing supplied with the search coil.
The PL search coil should be mounted such that the
conveyor belt passes above the plain surface of the
coil with the resin side facing down.
INSTALLATION RECOMMENDATIONS FOR
CONNECTING RFI FILTERS TO HIGH FREQUENCY
INVERTER DRIVES
Because of the complex circuit design used in these
filters a Ground Leakage Current of 8 to 80MA may
be observed. It is possible that nuisance trip ping of
extremely sensitive type of ground fault cir cuit breaker
may occur so this figure should be considered when
choosing such a device. It is im portant to provide
well-defined paths for the high frequency currents
involved. The best results are achieved when both
filter and inverter are mounted securely on the same
conducting, grounded backplate and not on rails etc.
