Pack sensors
The pack sensors need to be kept clean to ensure correct operation of the 700 series machine.
The sensors may be mounted overhead or across the deck of the conveyor, one at the infeed conveyor &
one near the end of the scale conveyor. The sensor type is normally a optoelectronic type.
The overhead sensors are mounted higher and point down to a reflector mounted in the conveyor deck.
Ensure there is nothing blocking the sensing path, e.g. – no debris is resting in the conveyor where the
reflector is.
If the machine has across the deck type mounted sensors, the sensors are mounted at the back of the
conveyor and the reflector for each sensor is mounted at the front of the conveyor.
The sensor face and the reflector can be cleaned with a soft lint free cloth, moistened with dilute detergent.
When clean, and after the machine has been switched on, check the operation of the sensors.
