These validators offer two operating modes:
Working with continuous pulses.
When the programmed price is reached (or exceeded), the validator automatically
and continuously gives credit pulses corresponding to the amount introduced.
Input pin 6 serves as inhibition in the acceptance of coins. The range of inhibition is
configurable.
Example:
Price:
€ 1
Pulses for this price:
5 pulses
The user introduces
€ 2
The validator immediately provides 10 pulses 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, the corresponding service
credits will be supplied.
