G-13.6 Characteristic features of the system
Single blocking
Two blocks with six DIL switches each are installed on the back side
of the coin validator. They can be used to block individual coin
cannels. To do this the corresponding switch must be set to the upper
position. (If more than one channel is assigned to one type of coin,
e.g. for old and new coins or for different bandwidths all the switches
must be set to the upper position.)
Six output lines are assigned to the 12 coin channels (not valid for
totalizers). If an inserted coin is recognized the corresponding channel
receives a signal. If one type of coin is blocked externally the
corresponding output line is set to ground potential. Line 6 can be
used to block the whole acceptance (all types of coins).
Sorting outlets
A JST plug is installed on the pc-board. Hoppers or sorting gates can
be controlled by means of this plug. Signals can also be received
since these are bidirectional lines . If e.g. a hopper sends a "Full"
signal the coins are directed into the cash-box.
The validators can also be adjusted by NRI in that way that the return
line sends a sorting signal onto the 10-pole connecting cable.
String recognition
As a protection against manipulation with strings the coin validators
are equipped with a directional accept sensor. That means that a
coin signal is only given when a coin passes the light barrier coming
from the coin insert. To pull coins back out of the device is also made
more difficult by additional design measures.
For devices without a front plate the accept sensor is located on the
left side whereas it is located on the right side for devices with a
front plate.
Apart from that standard coin validators of the series G-13.6000 can
be equipped with a spring for additional support of this safety device.
