Self-Service station for unattended areas

Pre-pay power band system.
Power consumption measurement can be divided into 3 tariff bands limited by programmable momentary absorption thresholds (example: up to 4 Amp: Free of charge, from 4 Amp to 10 Amp: Tariff “1”, from 10 Amp to 16 Amp: Tariff “2”).
DESCRIPTION OF THE USE OF THE KEY
Inserting a key or electronic transponder card charged with pre-paid credit, the client can fill up on water or electric power or both. Note: Electric power and water supplies can be selected independently. Upon request, a separated Drinkable and Non-drinkable water supply unit can be provided. Delivery occurs with the removal of the key and continues until the all the credit has been used or the annulment of the operation with the restitution of the credit remaining when the same key is re-inserted. The control unit signals the credit loaded has nearly been used and the status of the user in every moment, in addition to supplying instructions on the display during the delivery of service in the user language selected. Credit is detracted on the basis of the power or water effectively consumed (flowmeters or turbines are not used to read water consumption).

NOTE-1: With the pre-pay system, the power supply unit permits the automatic switch-on of the night light without requiring the presence of a special lighting line.

The display can provide information in 8 languages (and others on request).
