Table 6 Meter credit deduction example
The non-disablement calendar is a set of defined periods of time where the
meter will not open the supply control switch if credit runs out.
Note that if a meter has its supply control switch opened when the non-
disablement period begins it will not be possible to close the supply control
switch without first providing sufficient credit to pay the OWED value or by
accepting emergency credit if available.
Non-disablement periods are defined by means of a switching table which
consists of a schedule and special day table.
All switching schedules are controlled by the calendar clock; the maximum
settable parameters are:

Up to 20 special days

1 schedule table supporting up to 22 switching actions
An example of this can be seen in the following table.
