3.8. Motor control
Connecting and interrupting the +12 or +24VDC supply controls the motor.
The motor is automatically stopped when the power-supply is switched off.
Motor duty cycle is 2:1.
An electronic overload detection system protects the motor and in case of a coin jam it will temporarily
turn the hopper disc several times in the opposite direction until the jam is solved if not the motor switches
itself off.
3.9. Current consumption
With maximum coin load: 850mA average.
Current is zero whilst stopped (hopper disconnected).
Motor start-up and reversing surge: 2A falling to approx. 850mA (hopper full) or 400mA (hopper empty)
after 200ms.

Power supply requirements
12VDC and 24VDC nominal (± 10%)
maximum ripple voltage ± 2.4V
absolute maximum voltage: 26.4VDC
minimal voltage when using 24VDC connection: 18VDC
minimal voltage when using 12VDC connection: 10.8VDC
switch / reverse current: 2A

Coin counting
Coin counting speed is 6 to 7 coins per second. All paid out coins pass by the optical sensor indirectly.
The coin exit output changes from high impedance to low impedance status.
This output stays high as long as the hopper is in the “Off” status (power disconnected).
When a coin appears at the counter pawl under the exit bridge the PCB controls the coin verification
and releases a logic signal. The opto-coupler and the counter pawl detect paid-out coins.
Payout signal: open collector NPN - active low, maximum sink of 25mA at 35Volt maximum.
Minimum time obstructs optics 30ms - minimum.
Time between coins: ±100ms.
