Example:
Price:
€1
Signal for this price:
60
seconds
The user enters
€2
The validator immediately gives a signal of 120 seconds on the corresponding pin
Working in continuous mode with start request.
When it reaches (or exceeds) the programmed price, the user needs to request the
service through pin 6. Once this happens, the time will be provided continuously.
For the start request to be valid, it is necessary for pin 6 to produce a change of
status "inactive" state (which can be "0" or "1" as it is configured) to the "active"
state for a minimum of 50 milliseconds. This pin has to go back to the inactive state
during a minimum time of 50 milliseconds to make the sale of the next signal.
If the introduced amount was higher than the price, but insufficient to achieve the
value of another service, the remaining value will be stored.
Figure 2. Signal Times
Example:
Price:
€1
Signal for this price:
60 seconds
User introduces
€2
Until the user requests the service on pin 6, the validator will not send service. Once the
user requests the service, the validator will give a signal of 120 seconds to the
corresponding pin.
Working in Service Request Mode.
When the programmed price is reached (or exceeded) the user needs to request the
service on pin 6 to obtain a service. Once this happens, one service time will be
provided.
