4.2. Typical Operational Displays
4.3. Happy and Sad Faces
These two icons are used in combination to give a quick visual indication of good and bad
status. For example, if the meter were operating normally, the happy face would be on.
However, if it were to be tampered, the sad face would come on. Similar responses would
apply during token entry e.g. entering an invalid CTN would result in the sad face flashing for
a short period of time.
4.4. Contactor Status Indicators
Two icons are used to indicate the status of the load-switch (an internal latching relay).
Under normal operating conditions i.e. with the meter in credit, the load switch will be ‘closed’
and power is supplied to the consumer. A second ‘open’ indicator is used to indicate that the
latch is open, e.g. when credit expires.
