4.1
Load switch Status Indicator
This icon indicates the s
tatus of the meter‟s internal load control switch.
Under normal operating conditions i.e. with the meter in credit, the load switch
will be „closed‟ and
power supplied to the consumer. It will „open‟ when credit expires.
4.2
Alarm Indicator
This is a „low credit‟ warning indicator that turns on if the remaining credit value is greater than zero,
but less than half the low credit level programmed into the meter. Under these conditions it is
displayed in conjunction with the smallest credit wedge icon on the LCD.
4.3
Remaining Credit Indicator
This „wedge‟ provides a quick visual indication of the remaining credit in the meter and functions as
follows:
Displays all four credit wedge icons if the credit register is greater than, or equal to, the high
credit level.
Displays the three smallest credit wedge icons if the credit register is greater than, or equal to,
the low credit level but less than the high credit level.
Displays the two smallest credit wedge icons if the credit register is greater than or equal to half
the low credit level, but less than the low credit level.
Displays the smallest credit wedge LCD icon if the credit register is greater than zero, but less
than half the low credit level.
If the remaining credit is less than or equal to zero, all the credit wedge icons will be off.
When the remaining credit level reaches zero, the numeric display indicates
0.0kWh. If, for any reason, the credit level is decremented below zero i.e.
negative, the display indicates 0. kWh. This is the case if the meter has been
personalised not to display negative credit. Although there is no negative value
displayed, it gives a quick visual indication that a negative value is present.
The Remaining Credit Indicator‟s function varies slightly, depending on which mode the meter is
operating in.
In prepayment mode, the wedge segments toggle at pre-defined (token-settable) credit levels.
In energy limiting mode, the wedge icons are continuously scrolling from either left to right or
right to left. If the amount of energy being consumed by the connected load is less than the rate
at which energy credit (DAE) is being added i.e. the overall energy credit level in the meter is
increasing, it scrolls from left to right. If the amount of energy being consumed by the
connected load is more than the rate at which energy credit (DAE) is being added i.e. the
overall energy credit level in the meter is decreasing, it scrolls from right to left.
The rate at which energy credit is added depends on the value of the DAE. This
value is typically set to zero at the time of manufacture and can then be set to any
value with an appropriate engineering token from the prepayment vending system
at the time of installation.
4.4
Information Indicator
This icon turns on in response to pressing the information key on the keypad. It indicates that the
meter is in information mode and the contents of various registers can be viewed.
