Instruction

1. Local Offline Vending mode:

For STS keypad meter, After the customer recharges in POS station or agency station, the recharge token code is generated in PVMS system and printed on a receipt, and when back home the user inputs TOKEN on meter keypad or User Indoor Unit to realize the recharge business; the meter will be closed after the user successfully recharges; the utility can read the meter frozen data or implement local parameters setting by the HHU Field Tool.

For STS Smart meter without Keypad, customer recharges then get the TOKEN code in vending station mentioned above, and when back home the user inputs TOKEN on UIU (User Interface Unit), the TOKEN will transferred to meter and charged success if the TOKEN is valid. The UIU is RF wireless or PLC connected with smart meter.

For IC card or RF card STS meter, after the customer recharges, the recharge token code is written to card by card reader, and when back home the user insert the card into meter to realize the recharge business; the utility can also read the meter frozen data or implement local parameters setting by the IC/RF card.

2. Remote online Vending mode:

The remote online vending is based on modern AMR/AMI system with two-way communication network. HES system is required for remote meter data reading and command setting, including the TOKEN transmission.

For smart meter, After the customer recharges in POS station or agency station, the recharge token code is generated in PVMS system, and delivered to the end meter through the communication network; When the user's remaining credit and friendly threshold reach the limit, the meter relay automatically trips, the insufficient balance is reported to the HES/PVMS system, the meter will be closed after the user successfully recharges.
