Account Events; Connecting/Disconnecting Supply Remotely; Detecting And Logging Events - Secure Liberty 100 Technical Reference Manual

If the user confirms the action by pressing key 'B' within 30 seconds of pressing key 'A' the switch will close and
the default display of the current mode will resume otherwise the display will revert to the Ready mode display
cycle.
Note: The supply switch connection displays are not shown during the switch cycle test in commissioning mode.

5.15.4 Account Events

Liberty 100 is programmed to disconnect the supply outside of Friendly Credit periods (see Section 5.5.3) when
its account balance is insufficient and Emergency Credit (see Section 5.5) is not enabled or has been
exhausted. Once disconnected, the supply cannot be restored unless sufficient credit is added to the meter's
account to drive the switch to the READY state.
After supply disconnection, the meter's switch can be returned to the READY state by either enabling
Emergency Credit (provided Emergency Credit is not exhausted) or adding sufficient credit to bring the meter's
account above its Zero Credit threshold. Once in the READY state the user can close the switch from the meter
keypad or IHD.
Unless configured, Friendly Credit does not stop the Low Credit, Zero Credit or Zero Emergency Credit alerts
from being given.

5.15.5 Connecting/Disconnecting Supply Remotely

Liberty 100 will accept remote requests for supply disconnection from an authorised source even if the supply is
in an off state due to another reason such as no credit in the meter. When this occurs the switch will not change
to a 'READY' state even if a user vends to the meter's account and puts it back into credit if a switch open
command from the authorised source has not been rescind. Supply restoration is only possible when there is no
reason for the main switch to be open.
A retailer can remotely operate the meter's switch by sending an authenticated supply UTRN to the meter. The
meter's switch can be remotely changed from On to Off state or from Off to READY state either immediately or
at a scheduled later date and time (in 30 minutes resolution); the scheduled date must be within 365 days
(compile time configurable) from the current date. The meter will not accept a supply UTRN for any scheduled
date which is more than the configured number of days.
Once disconnected, the supply can only be restored by user interaction at the meter or IHD when notified that
the meter's switch has been put into a 'READY' state. The meter will confirm supply restoration with a visual and
audible alert. Alerts or change of the meter's switch state (On, Off or READY) are also communicated to the IHD
and HES (if configured).

Detecting and Logging Events

The meter events should be checked periodically.
Liberty 100 detects the following events and stores a maximum of one hundred (100) of each type on a rolling
first in first out (FIFO) basis in separate storage groups:
● Hardware events
● Quality of supply events
● Tamper events
● Prepayment events
● UTRN events
