The power switches are optional. These switches can be used for additional security regarding hopper
payout. By powering the hopper first with the logic supply, the presence and hopper status can be
checked by testing the security and coin exit outputs. If the hopper is Ok, the power switches may be
activated to start hopper payout.

7.3 Hopper control

As soon as the hopper logic power supply is present, the hopper will set the operating mode by
reading its In1 and In2 inputs. See Table 3: Mode selection input logic for all modes.
The mode can be set by hardwiring In1 and In2 or by logic control by the machine.
Controlling the In1 and In2 inputs by the machine gives the possibility to put the hopper temporarily in
RESET mode to check the opto-sensors and coin exit output.
As long as the hopper logic power is present, the hopper mode can not be changed, except for the
RESET mode. Entering RESET mode can be done always. After leaving the RESET mode by
changing the In1 and In2 level again, the hopper performs an internal reset, and the new operating
mode is determined from the In1 and In2 levels.

7.3.1 Mode 0

If the hopper is set in mode 0, the hopper is started by applying Vmotor to the hopper. This can be
done by switching the 24V power line, or by switching the 0V line or both. The hopper is braked as
soon as Vmotor is switched off. Note that in order to prevent any over-payouts, the hopper should be
braked at the first (falling) edge of the coin exit output pulse.

7.3.2 Mode 1

In mode 1 the hopper is started by pulling the In3 line low to ground. The hopper is braked as soon as
the In3 line is pulled up again to Vlogic. Note that in order to prevent any over-payouts, the hopper
should be braked at the first (falling) edge of the coin exit output pulse.

7.3.3 Mode 2

In mode 3, for each active low pulse transmitted on In3, a coin is paid. The hopper will stop
automatically after the last start pulse.

7.3.4 Security Output

During normal hopper operation this output is active low. The security output will be pulled up to Vlogic
(high) if the opto-sensor is not working correctly (dirty, fraud or defect).
This output can also be used to check the presence of the hopper (output should be low then).

7.3.5 Coin Exit Output

As soon as a coin enters the opto exit window, the coin exit will go active low (after a small digital filter
5ms) and go up again (pulled up) when the coin leaves the coin exit window.
If a coin blocks the opto-sensor for more than 1 second, the hopper motor is braked and started again
as soon as the opto is not blocked anymore.
If the opto-sensor has become too dirty, the coin exit will remain low.

7.3.6 Low Level and High (Top) Level output

These outputs are directly attached to the plate sensors of the Evolution Hopper. The must be pulled
up by the machine. When the hopper is filled with coins these plates are shorted to the ground plate
via the coins. During payout the coins will move over the plates causing changing signals on the
outputs. The best moment to check the coin level outputs is when the hopper is not paying out.
