AL55/66 Technical manual Version 1.1
4. Functional versions
ALBERICI coin selectors support the possibility to adjust coin selector to various
applications. For user this gives the great flexibility. With same type of coin selector
user can have uniform spare stock and reuse same coin selector in different machines.
This technical manual describes only basic functional versions supported with
programming software. After version selection simply make one “click” and coin selector
function will be changed.
Every function has additional options and data that could be selected or changed by
user

.
Experienced users can create they own “custom” functions, and our company will
provide all necessary support and help.
Basic functional versions are:
- Validators
- Totalizers
- Timers
- Multi-price steppers
4.1 Validators
Validators are type of coin selectors that use output pins of interface connector to
transfer simple pulse as information about coin that has been detected. Mostly they use
parallel interface with host machine. Coin type is detected by pin number that has been
activated. I special case validator could be serial and pass the information to host as
number of serial pulses according to accepted coin relative value.
The problem with serial transfer is time for transfer that in some cases could be
significant. That is the main reason why parallel validators are in use.
Parallel validators have several versions:
- Standard parallel
- Parallel combinatorial (EVA standard)
- Multi-impulse parallel
- Parallel with Spanish protocol
4.1.1 Standard parallel
Standard parallel validator is most commonly used. Most of coin selector producers
support that type of function.
Coin selectors with 10 pole connectors use 6 outputs to indicate coin type that has been
detected and accepted. One input called “inhibit” is used to block acceptance of all
coins. Some validators have also one output as indication of return or “flight deck”
opened. After the acceptance of one programmed coin, corresponding output is
activated for a brief time period. Active level is mostly “low” and period is typically 100
ms.
For coin selectors AL55/66 user can program time period from 5 to 1000 ms in steps of
5 ms. Using programming software all output timing will be set at same values but
different timing period could be easily programmed for each output separately
(
custom
).
