Installation
The supply to the conveyor must be either 5-core cable (3-core cable is suitable for single
phase machines) fed through a flexible conduit or 5-core armoured cable . Insert the cable
through the gland.
Do not use rigid conduit of any type. Rigid conduit can lead to vibration being transmitted to
other components, resulting in spurious triggering / rejects.

Do not start the machine and initiate the use of any electrical circuitry before the Loma
commissioning engineer has approved the installation.
Checking Guards
Check that all guards are securely fastened in place.
On some conveyors that are made to special order, hatches may be fitted to permit access to
some areas of the machine. These hatches are generally fitted with electrical interlocks which
prevent the machine from operating whilst a hatch is open. Check that all hatches are closed.
Check that the infeed and outfeed areas of the conveyor are clear of obstructions.
Checking Belt Tracking (PV belt system only)
The belt must be checked for correct tracking before running the conveyor for any length of time. If
belt tracking needs to be reset. See Conveyor Belt Maintenance for further details.
