ANTI-TAMPER CONDITIONS
The SA2005P cater for the following meter tamper conditions and are indicated as follows:
Method
Description
Result
Phase
Voltages
One LED is provided for each phase to indicate abnormal
operating conditions.
During normal conditions, the LEDs
are continuously switched on.
Phase Failure, In case of a phase failure, the corresponding LED is
no voltage switched off.
The SA2005P will record the energy
consumption accurately under this condition
Phase
Sequence
Error
In case of phase sequence error, all LEDs are flashing with a re- The SA2005P will record the energy
petition rate of approximately 1 Hz. A connection of a line voltage consumption accurately under this condition
to the neutral terminal would be indicated in the same way.
Input / Output
Terminals
Interchanged
One LED is provided for each current sensor to indicate reverse
energy flow. If detected, the corresponding LED is switched on.
The SA2005P can be configured to accumulate the absolute
energy consumption for each phase measured, irrespective of
the direction of the energy flow.
The SA2005P will record the energy
consumption accurately under this condition
Missing
Neutral
Connection
The architecture of the meter should provide for a good "phantom In this case, the meter would register the
neutral" in cases where the neutral is disconnected from the
energy consumption correct.
meter.
Return
The SA2005P will therefore record the energy consumption
through Earth accurately under this condition.
A indication for this condition could be
realized external to the IC.
Load
Imbalance
Calibration
The calibration data is stored in an EEPROM. There are no
trim-pots required in this design.
The SA2005P will record the energy
consumption accurately under this condition
The meter can not be re-adjusted, only
reprogrammed.
