seconds from 00 to 59. Minute and second count are separated with decimal point
except in case of 8 digit LCD where one blank digit is used as separation mark.
Time and imported value or rest value is not possible to present at the same time

Currently only error messages of display are supported.
In case that value on display is not possible to present(
out of range
) display will show
character
E
. Coin selector function will be correct. Example of error on display is when
number of credit to be displayed is more than 9 credits and we use display with only
one digit. Next example is in case of very long time period over 99 min and 59 seconds
which is theoretically possible to program if time multiplier and base time is big
enough!
Display with 8 digits has 12 segments per digit and some advance text message will be
possible to present in future or on customer request!
5.5 Rest management
The rest management is additional function available to use in all types of coin selectors
when there is some rest of accumulated value after credit activation or vend process.
Usually is used in dual stepper or multi price stepper or some time even with timer or
totalizator. User can select different options: to cancel the rest value(
set time to 0
), to
keep it permanently(
till power off
) or to cancel this value after time period that could be
programmed from 1 to 254 seconds.
Default setting is to keep rest permanently(
timer set to 255
).
After first coin insertion timer will be stopped and restarted again after next credit or
vending activation.
5.6 Fraud inhibit
ALBERICI coin selectors has advanced control of coin acceptance and protection against
the all kinds of fraud. The most common fraud is called “jojo” or coin on string. First of
all there is mechanical protection with wire cutter and anti-fishing hooks. Some models
(AL66K3) has 3 opto sensors for coin position and direction control.
Precise optical pulse timing measure is done to distinguish false movement of coin.
Deviation in direction or timing limits will be recognized as fraud and coin will not be
accepted as valid(
no credit
).
To make fraud attempt much difficult after fraud detection it is possible to block
acceptance for programmed time period(from 0 to 254 seconds). If time period is
programmed with value 255 than inhibition of acceptance will be active till next coin
insertion. Next coin there fore will be rejected.
