Safety And Maintenance
3.3.1
Control circuitry must be arranged to disconnect power to the
mechanism when the host machine is opened for servicing.
Removal of the hopper connector, without first disconnecting the
power source, may result in damage to the optical sensors.
3.3.2
Over-current protection is not provided on the mechanism. Customers
are strongly recommended to provide suitable fusing arrangements in
event of equipment failure.
3.3.3 The mechanism control board detects a stall situation and initiates
motor reversals to free jams. Control circuitry should be arranged to
disconnect power if this situation exceeds 10 seconds maximum, to
prevent motor damage.
3.3.4
Servicing and maintenance staff must be adequately trained and aware
of the hazards arising from the rotating disc. Fingers, long hair and
loose clothing, including ties, must be kept clear at all times.
3.3.5
Avoid handling the unit by the bowl only, as this could become
detached if not correctly located, thus causing possible injury or
damage.
3.3.6
Prevent foreign objects such as elastic bands, paper clips and screws
from entering the hopper bowl.
3.3.7
Regular cleaning of optical sensors is advisable to prevent miscounting.
3.3.8
When cleaning the bowl, use a diluted neutral detergent and dry with a
clean cloth.
3.3.9
Wiring errors are a common cause of problems, particularly with the
sensors which can be damaged with a relatively small voltage overload.
