Manipulation detection (option)
In case manipulation is detected while a coin is being accepted the coin validator emits a foul
signal and a string signal as an option.
5.9.1
Foul signal (only v² eagle BACTA)
The coin validator reports a manipulation of the acceptance gate by transmitting a foul signal
(pulse length: at least 600
ms) via all signal lines in the standard mode (in the binary mode: via
all signal lines except for the strobe line). Coin acceptance is inhibited.
5.9.2
String recognition
To ensure that no coins suspended from a string can be inserted into the coin validator or that
the acceptance gate cannot otherwise be tampered with, the coin validator can be equipped
with an optical string sensor (cannot be retrofitted) in the acceptance area which recognizes
both tight and loose strings.
The construction of the acceptance gate (dismounted in figure) makes
the string go through the light beam between the two optical
sensors. If the acceptance gate is completely closed, the string
changes the light signal. If the acceptance gate is slightly
open (tight string), the light beam is directly interrupted by
flag on the acceptance gate.
If the sensor recognizes a string, coin signal line 1 or 6
of the BDTA interface sends a string signal, or the BACTA
interface sends a foul signal
(cf. Chap. 5.9.1 Foul signal (only v² eagle
to the machine, and the coin is not accepted.
At first, coin acceptance is inhibited for 30 seconds. If the
string is not removed within this time period and the sen-
sor continues to recognize it, coin acceptance remains
inhibited and in addition all "jammed coins" are automatically released.
Whether in case of the BDTA version the string signal is transmitted via coin signal line 1 or 6 is
determined by customized factory programming
(cf. Chap. 10.2.1 BDTA interface, p. 46)
.
Sensitivity of the string sensor
To enable faster testing of the string sensor for functioning, coin acceptance is
not inhibited when diagnosis is performed. When the string sensor is activated
only a string signal is transmitted.
