Electrical Installation - Advanced Detection Systems 1200E Series Installation Manual And Owner's Manual

ELECTRICAL INSTALLATION

WARNING: Whenever wiring is to be done to the terminal strip of the
detector, make sure ALL sources of power have been disconnected. Terminals
3 through 9 may be powered from sources other than those supplying the
metal detector. Caution should be used when working on machinery as
components may stop and start automatically without warning.
The metal detector operates from a single phase supply, 115/230 VAC +10%.
Use a power feed that is free of motor start-up transients or other
interference. A dedicated circuit is recommended but not required as long
as the power feed is "clean."
All power supply grounds for the detector, conveyor, and reject devices
must originate from a single point. Multiple grounds should be avoided to
minimize electrical noise.
Electrical connections to the metal detector are made via a terminal strip
housed inside of the control cabinet. A terminal connections chart is
located on page 4 and on the inside of the detector's front cover.
Occasionally, because of excess electrical noise on the incoming power
lines, it is necessary to use a constant voltage transformer to remove the
interference. The transformer that we recommend, and its wiring diagram
is show in FIGURE 8 near the end of this manual.
Main power is applied to the metal detector via Terminals LI, L2, and Gnd.
The remaining terminals are used to wire conveyor stops, reject devices,
and alarm systems. The rest of this section describes the wiring of such
devices.
