Accepted coin sensors
To ensure that accepted coins actually arrive in the cash-box or in an
external sorting device and that coin acceptance has not been tampered
with, accepted coin sensors, positioned in front of the cash-box coin outlet
check whether the inserted coin drops unhindered into the cash-box chute.
A coin signal is not transmitted to the machine until the coin has passed this
checking function.
If the accepted coin sensors are continuously covered, e.g. by a coin pile-
up, coin acceptance is inhibited.
Exception: Casino model/mode
Due to fast coin acceptance the Casino model of the G-13.mft cannot utilize
the accepted coin sensors.
The accepted coin sensors are located in front of the cash-box coin outlet
and check whether a coin is directed into the cash-box. Usually, a coin signal
is only sent to the machine when the accepted coin sensors notice that a
coin is being accepted and directed into the cash-box (see above). To speed
up coin acceptance on the Casino model/in the Casino mode, the coin signal
is sent before the coin passes the accepted coin sensors. Consequently,
the acceptance gate of the coin validator is easier to tamper with, e.g. with
an inserted coin attached to a string.
For a balanced protection against manipulation, an accepted coin signal
independent of the coin signal can be transmitted via the return signal line
to the machine.
