When choosing the power supply line for the metal detector, it should be remembered that starting of heavy electrical machinery

creates very considerable (though momentary) voltage drops in the line. Such "spikes" can cause the metal detector to trigger.

Since the power consumption of the detector is very low (approximately twenty-five watts), it is recommended that a lighting

circuit be used for its supply rather than a machinery power circuit. Where this is not possible, and line noise does trigger the

detector, contact Goring Kerr for recommendation of a suitable isolation transformer or power line filter.

a) The metal detector connections are shown in the Power Supply Connections section. If the control unit is mounted on the

search head, the connections from the search head to the control unit are already made.

b) The cable between the power supply unit and control unit is of a specific type. Do not substitute or splice on

extra cable. Likewise, the cable between the control unit and search head (when remote) is of a specific type.

Do not substitute or splice on extra cable. Either cable can be cut to length and they are not sensitive to

movement. Contact Goring Kerr for extra cable or cable information if required.

c) Use waterproof cable glands at all cable entries.
