If the remaining amount is sufficient to provide another service, a new request is
required to obtain the service.
The request signals are sent to pin 6 one by one. For this to happen pin 6 must
produces a change of status "inactive" state (which can be "0" or "1" as is
configured) to the "active" state for a minimum of 50 milliseconds. We need this pin
to go back to the standby state for a minimum time of 50 milliseconds to make the
sale of the next service.
Figure 4. Signal Times
If the introduced amount was higher than the amount required, but insufficient to
reach the value of the price programmed, the remaining value will be stored.
Example:
Price:
€ 1
Signal for this price:
60 seconds
The user introduces
€ 2
Until the user requests the service on 6 pin, the validator will not work. Once the user
requests the service, the validator will give 5 pulses to the corresponding pin. A new
service request is required to obtain the remaining 5 pulses.
In both working modes described above, you may obtain several signals which provide
information on the Status of the validator:
Counter
signal. It is used to count the base coin values that are introduced into the
machine. It is variable and configurable, time "0" and "1" time. For example, if the
base coin is €1, when 2 coins of 50 cents (€1) enters the machine, there will be a
counter pulse to increment the counter, or when 5 coins of 20 cents (€1) enter the
machine there will also be a credit on the counter. This output pin signal is
configurable.
Available Credit
signal. Generally used to illuminate a lamp indicating the user's
credit. This output pin signal is configurable.
