6. Electronic Description

6.1 General Electronic Description

Operation of the hopper is controlled by an 8-bit microprocessor.
The firmware allows the choice of 3 different operating modes.
It also provides PWM motor control drive via a MOSFET bridge and an optical pay-out detection
output.
Separate power supplies are recommended for the motor supply input and the logic supply input.

6.2 Operating Mode Selection

Three modes of operation are available, selected via inputs IN1 and IN2 (pins 4 and 8 of the 12
way connector). Input signals may be controlled by the host machine, or may be hardwired.
Additionally, input IN3 (pin 12) is the logic control line, used in modes 1 and 2. These inputs are
passive pull-up and active pull-down.
The signals therefore default to logic “1” if left open circuit.
NOTE: It is strongly recommended that if these inputs are to be controlled by the host machine,
then open collector NPN transistors, referenced to logic OV (connector pin 2) be used to set the
input levels to IN1, IN2 and IN3.
The exception is the RESET mode, which can be applied at any time (with instantaneous effect).
Mode selection is determined at power up.
The hopper allows a 100ms timeout after power up, then reads the inputs IN1 and IN2. The hopper will
remain in the selected mode until the power is removed, i.e., any further changes in the levels at IN1
and IN2 will be ignored. See Table 3: Mode selection input logic.

Table 3: Mode selection input logic

6.2.1 MODE 0 DIRECT SWITCHING

This is the default operating Mode, and is selected when all of the input selectors are left
open circuit. When the 24V line is established, the motor starts in the forward direction and
when the 24V power line is removed, the motor is braked.

6.2.2 MODE 1 LOGIC CONTROL

In this mode the logic and 24V power supplies can be permanently connected and motor
function is determined via a logic level on the IN3 input.
When IN1 (pin 4) and IN2 (pin 8) are pulled down to OV at power up, mode 1 is selected.
The operation of the motor is now controlled via a logic signal on IN3 (pin 12). With the 24V
supply present, a low level on IN3 starts the motor and a high level on IN3 brakes the motor.

6.2.3 MODE 2 COIN COUNTING

In this mode, the hopper will pay out a coin for every pulse it receives on input IN3.
Mode 2 is selected by setting IN1 (pin 4) high and IN2 (pin 8) low at power up. Once
selected, the processor continually scans input IN3. When a pulse is detected on IN3, an
internal register is incremented. When a coin is paid out, it is detected and the register is
decrement.
The motor is started when the internal coin register is non-zero and is stopped when it
returns to zero. The maximum count for the coin register is 4095 coins. Should the 24V line
fail at any point, the motor is braked. When the 24V line reappears,
the pay-out of coins continues until the coin register returns to zero. Coin counting on IN3 can take
place while coins are being paid out. A pulse is defined as a falling edge followed by a rising edge.
Pulse edges may be no closer than 5ms. This is so that the processor has adequate time to poll the
IN3 pin and debounce. This represents a maximum pulse rate of 100Hz.
There is no lower limit. The waveform duty cycle is unimportant.
