Page 6: Introduction
Introduction Introduction Cashpower Gemini HMI is part of the Gemini family of prepayment meters and is a single-phase, keypad-based, stand-alone or split prepayment electricity meter in a British Standard housing. If used as a split prepayment meter, it comprises two parts, namely the meter and the customer interface unit. -
Page 7: Human-Machine Interface (Meter)
Keypad: The meter has a 12-key non tactile keypad with audible feedback. The keypad is used for entry of tokens and accessing various management functions and meter parameters via the information mode. The keypad also has a backspace key.

Similar responses would apply during token entry e.g. entering an invalid Credit Transfer Number would result in the sad face flashing for a short period of time. Cashpower Gemini HMI – User Guide © Landis+Gyr (Pty) Ltd... -
Page 13: Led Indicators
On the Customer Interface Unit, the alarm indicator functionality of the LCD is duplicated on a flashing yellow LED to give a very clear visual indication to the consumer that the credit level is low and disconnection of the electricity supply could occur soon.

Page 18: Electricity Credit Token
Clear Credit Token On accepting a clear credit token, the meter clears any remaining credit to zero and opens the load switch, thus interrupting the electricity supply to the customer. Cashpower Gemini HMI – User Guide © Landis+Gyr (Pty) Ltd... -

On accepting a set credit metering mode token, the meter commences operation as described in section 10. 7.3.13 Set Prepayment Metering Mode (Meter-Specific Token) On accepting a set prepayment metering mode token, the meter commences operation as described in section 9 Cashpower Gemini HMI – User Guide © Landis+Gyr (Pty) Ltd... -
Page 20: Set Energy Limiting Mode (Meter-Specific Token)
Power limiting is not a form of safety overload protection. It is designed to generally limit the overall usage of power in a particular area (possibly dictated by reticulation limitations or linked to a tariff allocation). Cashpower Gemini HMI – User Guide © Landis+Gyr (Pty) Ltd... -
Page 21: Reverse Power Detection And Metering
From a safety point of view, the meter must not be powered when accessing this port – the Credit Reader provides the necessary low-voltage supply to power the logic circuitry. Cashpower Gemini HMI – User Guide © Landis+Gyr (Pty) Ltd... -
Page 22: Anti-Tamper Features
Once the terminal cover is fitted to the meter, check that the tamper switch is fully depressed by checking the tamper switch status in the meter state registers. If a meter has been tampered, normal operation can only be restored by entering a clear tamper token. Cashpower Gemini HMI – User Guide © Landis+Gyr (Pty) Ltd... -
