Isolate the electrical and compressed air supplies to the system.

Alternatively, if cleaning the conveyor belt with the power on, isolate the compressed
air supply to the system and then turn the X-Ray key switch the CLEANDOWN position.
3.
Check that there is no build-up of debris on the conveyor.
4.
Check that the belt and rollers are clean and free from a build-up of either product
or foreign material, e.g. wrapping film. Material on the rollers may cause incorrect
tracking of the belt.
5.
If there is a significant spillage of wet product onto the belt then remove the belt,
wash it down to ensure that it is clean and then dry both the underside of the belt
and the bed of the conveyor thoroughly with a paper towel or air-line before refitting.
This is required to prevent the underside of the belt sticking to the bed of the
conveyor and potentially causing the motor to overload.
6.
Check that the reject bin is not full, this is particularly important if a Bin Full detection
device is not fitted. If, necessary, empty the bin in accordance with company
practice.
7.
Either wipe or wash the system using a mild detergent solution and then rinse using
clean water. Pay particular attention to the centre section of the main cabinet as this
area is not seen when in production.
8.
Clean / wipe any photoelectric cells (PEC) and reflectors.
9.
Clean / wipe the lead impregnated curtains on the infeed, inner left, inner right and
outfeed areas of the system.
10.
Check that the air regulator unit water trap is clean and the outlet is not blocked.

Reconnect the electrical power and compressed air supplies to the system or if in
CLEANDOWN mode turn the X-Ray key switch to the ON position.
12.
Check that the conveyor belt is tracking correctly.
