Latching Relay Status Indicators
Two icons are used to indicate the status of the internal latching relay.
Under normal operating conditions i.e. with the meter in credit, the latch
will be „closed‟ and power is supplied to
the consumer. A second „open‟ indica
tor is used to indicate that the latch is open, e.g. when credit expires.
Under normal operating conditions e.g. with the meter in credit, the latch
will be closed. It will open when credit expires.

Information Mode Indicator
This icon turns on in response to pressing the i-key on the keypad. It indicates that the meter is in information
mode and the contents of various registers can be viewed.
Note that the information mode automatically times out after a period of 1
minute in the absence of any further interrogation.
3.7
Power Indicator (kWh)
This function is used whenever the displayed units represent power (kWh). It applies to both normal meter
operation, and when viewing registers via the information mode.
The icon will be ON when the latch is closed and the load exceeds the minimum creep load (typically 40mA)
and the icon will be flashing when the latch is open and there is no load in excess of the creep limit.
The power (kWh) icon will flash on and off if no measurable energy is being
consumed.
3.8
Power (W) Indicator
This function is used whenever the displayed units represent power (W), such as instantaneous power, or
power limit setting. It applies to both normal meter operations, as well as when viewing registers via the
information mode.

Remaining Credit Indicator
This „wedge‟ provides a quick visual indication of the remaining credit in the meter.
The actual credit levels at which the individual bars in the „wedge‟ icon
toggle are personalised at the time of manufacture but can be changed at
any time with a maintenance token.
The indicator functions as follows:
All four credit wedge icons are displayed if the value in the current credit register is above the
pre-set high credit level.
The three smallest wedge icons are displayed if the value in the current credit register is
somewhere between the pre-set low credit level and high credit level.
The two smallest wedge icons are displayed if the value in the current credit register is
somewhere between the pre-set low credit level and half of that level.
The smallest wedge icon is displayed if the value in the current credit register is somewhere
between zero and half of the pre-set low credit level.
All the credit wedge icons will be off when the meter runs out of credit (zero or negative
values).
