Routing the cable between the search head and the control box
The 12-core screened cable supplied must be used to join the search head to the control
box.
NOTE: Do not route the cable with any electrically noisy wiring, such as mains supplies.
Static precautions for dry powder products
For products likely to generate static it is essential that the product pipe which runs through
the aperture is fitted with an antistatic screen. Please consult your Loma Service Centre for
details.
Connecting electrical supplies
The standard Loma stand-mounted freefall metal detector requires a single-phase electrical
supply. Electrical connections are made to a connector block inside the control box
The following illustration shows the connection arrangements at the connector block:
The main incoming earth connection is made to the
left-hand control box ground stud (in a group of 3)
located just below the right-hand edge of the control
board.
• Power cabling must be rated at no less than 5A current carrying capability and be routed
into the control box by a suitable watertight gland. The power input gland hole is on the
extreme left of the control box when facing the controls.
• Power cabling for a UL approved model is 20-16AWG fed from a locally positioned switch
or circuit breaker that is within easy reach of the operator. The breaker must be labelled as
the disconnecting device for the equipment. Cable tightening torque is 5.5in/lbs routing
into the control box as in the above diagram
NOTE: Do not use rigid conduit of any type. Rigid conduit can lead to vibration being
transmitted to the head, resulting in spurious triggering.
• Open the control box door and remove the safety cover angled terminal access plate only
from the power supply cover. Place it in the bottom of the control box door.
