Technical Information: HOPPER U 3
Small hopper Medium hopper Large hopper
L=115 mm and 250 coins L=115 mm and 400 coins L=115mm and 600 coins
ÔMicroprocessor controlled PCB control board.
ÔAnti jam and anti span systems.
Jams. These hoppers have a current draw detection system to manage the possible
coin jams that may occur. When the detection system activates, the spin of the hopper
motor is reversed for 1.5 seconds to free the jammed coins.
Spans. The time span between the extractions of two coins is called a span. When a
span of more than five second is detected, the hopper reverses the movement of the
motor for 1.5 seconds to move the coins in the coin bay so that after the movement
the coins are in a better position to be extracted.
ÔAuto detection of errors and faults. Depending on the communication protocol used,
the number of errors that are detectable will be different.
ÔA useful life of 2 million coin extractions.
ÔDifferent systems to control the filling if the hopper: optic sensors, mechanical scales
or overflow.
ÔEmpty detection using optic sensors.
ÔDifferent communication protocols with the machine: serial or parallel.
When using parallel protocol the machine manages all the signals separately: one
wiring loom for each hopper.
When using cctalk communication protocol, the communication is carried out through a
bidirectional data line (DATA). This solution radically simplifies the wiring and therefore
the cost of the machine.
