Operation
Determine in advance how your hopper must operate, since it will be necessary for you to choose the type of
operation best suitable for your requirements.
This hopper can work in three different modes,
Type0 Type1 Type2 …
4.1
Selection of conditions
The logic state of these inputs, that is, the operation mode that the hopper will be using, is detected only at
power up or reset.
The selection of conditions can be made by IN1 and IN2 inputs (pin 4 and pin 8). The following table shows all the
possible combinations to this purpose.

4.2
Type 0
By this operational mode the hopper dispenses continually the coins. Both pin 4 and pin 8 must be +24V dc powered.
The control of the hopper is exclusively made by powering the hopper motor by 24 Vdc through pin 9 (+) and pin 1 (0).
4.3
Type 1
Both pin 4 and pin 8 must be set to GND potential (0 V).
The + 24 Vdc must always be present between pin 9 and pin 1 for the hopper motor, and the control of the
distribution is made through IN3 (pin12) by a negative (GND) signal.
This is the method commonly used.
4.4
Type 2
Pin 4 must be +24 Vdc powered, while pin 8 must be set to GND (0 V). The game board sends to IN3 as many GND
signals as the tokens / coins to be paid out.
The 16-bit register in the hopper board counts the signals received through IN3. Then the hopper will dispense as
many coins as the registered pulses.
The 16-bit register counts up to 65535 coins, more than any hopper can contain.
4.5
Reset
The reset simulates the switching-off, so it is not a functional condition but a command that can be activated at any time.
It allows to
restore correct operation, after an error occurred
.
After an error the device can be either reset or switched off and on again.
The reset also allows to modify the type of operation on condition that IN1 and IN2 are re- configured within
one
second
from the removal of the signals that produce the reset.
This command and the control of IN1 and IN2 must be managed by the machine pcb.
