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 is operating normally, the
happy face
will be on. However, if it is
tampered
, the
sad face
will come on. Similar responses apply during entry of the prepayment voucher e.g. entering
an invalid voucher will result in the
sad face
flashing for a short period of time. Note that an
out of
credit
con
dition is not considered to be a 'bad‟ status and the
happy face
will be on.
6.4
Alarm Indicator
This is a „low credit‟ warning indicator that turns on if the
current credit register
value is greater than
zero, but less than half the
low credit level
. Under these conditions it is displayed in conjunction with
the smallest
credit wedge
icon
– 11.9.
6.5
Load Switch Status Indicator
This icon indicates the status of the
load-switch
. If it is closed, electricity is supplied to the customer. If
it is open, the custom
er‟s electricity supply is disconnected.
Under normal operating conditions e.g. with the meter in credit, the
load switch
will be closed. It will
open when credit expires.
6.6
Remaining Credit Indicator
This 4-
segment „wedge‟ provides a quick visual indication of the
remaining credit
in the meter and
functions as follows:
All four
credit wedge
icons are displayed if the value in the
credit register
is above the preset
high credit level
.
The three smallest wedge icons are displayed if the value in the credit register is somewhere
between the preset
low credit level
and
high credit level
.
The two smallest wedge icons are displayed if the value in the
credit register
is somewhere
between the preset
low credit level
and half of that level.
The smallest wedge icon is displayed if the value in the
credit register
is somewhere between
zero and half of the preset
low credit level
.
All the
credit wedge
icons will be off when the meter runs out of credit (zero or negative values).
NB: The actual credit levels at which th
e individual bars in the „wedge‟ icon toggle are personalised at
the time of manufacture but can be changed at any time with an engineering voucher from the
prepayment vending system.

interrogation.
