Installation

Post Installation Problems

■ Spurious Triggering

The Loma range of detectors is the product of many years experience and development. They

are inherently reliable, provided that it is installed and set up correctly. Remember that the

detector can detect can detect moving metal anywhere within its metal free zone. This is up to

a distance of 3 times the smaller of the aperture dimensions away from the detector.

Connecting the Detector Head Electrical Supplies

Connection of an electrical supply to the metal detector head must only be carried out by

suitably trained and qualified personnel.

The supply voltage for the search head is indicated on the identification/rating label that is etched on

the back of the search head. Diagrams are included to provide details for connection of the head to a

suitable electrical supply and also for connection of the head to reject mechanisms, warning alarms

and other external devices.

The following guidelines should be observed:

■

The power source chosen should be clean and independent of any other equipment and have

a good ground / earth connection.

■ Power cabling must be rated at no less than 5A current carrying capability and be routed into

the control box area through one of the four gland entry holes provided.

■ Power cabling for a UL approved detector is 20 -16AWG fed from a locally positioned switch

or power breaker that is within easy reach of the operator. The breaker must be labelled as

the disconnecting device for the equipment. The cable tightening torque is 5.5in/lbs, routing

into the control box area as described above.

Do not use rigid conduit of any type. Rigid conduit can lead to vibration being transmitted to

the head, resulting in spurious triggering.

When

refitting the head control panel cover the cover fixing screws must be tightened to 4Nm torque to

maintain the integrity of the IP69K rating for the head; preventing ingress of water or condensation.

The electrical supply is connected to the Mains Filter located inside the detector head front panel and

then distributed around the head via a MEANWELL Power Supply.

To connect an electrical supply, proceed as follows:

1. Remove the six front cover retaining bolts and drop

down the cover until it is held against the supports
