Control signal to hopper
If the hopper is in standby mode (after start-up), the machine may activate
the hopper motor at any time by transmitting a signal via the control line
(voltage drop). The motor turns the payout disc as long as the signal is
present. The hopper thus pays out coins until the voltage is increased again.

Coin signal to control system
The hopper transmits a short signal (30 ms) to the control system via the
coin line (voltage drop), whenever the sensor located in front of the hopper's
coin outlet is covered by a coin.

Error signal to control system
The hopper detects malfunctions such as coin jams or defective plug
connections/cables, and informs the control system by transmitting a
certain number of short signals via the error line (voltage drop, 1:1 pulse
pause ratio, 10 ms; 100 ms between pulse intervals of 1–8 pulses).
