	Explanations without specific type details apply to both types.
Purpose	The user manual contains all the information required for application of the
	meters for the intended purpose. This includes:
	• Provision of knowledge concerning characteristics, construction and
		function of the meters
	• Information about possible dangers, their consequences and measures
		to prevent any danger
	• Details concerning the performance of all work throughout the service
		life of the meters (parametrizing, installation, commissioning, operation,
		maintenance, shutting down and disposal)
Target group	The contents of this user manual are intended for technically qualified per-
	sonnel of energy supply companies responsible for the system planning,
	installation and commissioning, operation, maintenance, decommissioning
	and disposal of the meters.
Conditions	The user of this manual has received instruction in basic electrical princi-
	ples, in particular the various principal types of circuit for energy measure-
	ment.
Subdivision	This user manual is divided in a logical manner suitable for learning and
	application, i.e. the individual chapters follow the sequence of information
	probably required during the various phases of the service life of the me-
	ters. This provides the following structure:
	•	Chapter 1	Description of unit
	•	Chapter 2	Safety
	•	Chapter 3	Construction and Function
	•	Chapter 4	Control elements and displays
	•	Chapter 5	Programming / Interrogation Interface
	•	Chapter 6	Installation and commissioning
	•	Chapter 7	Data readout
	•	Chapter 8	Metering testing

General view of meter

Residential metering

The S2AS meters form a family of solid state single phase meters to cover the whole range of residential metering applications. Single or two rate register, pulse output and communcation interface according IEC 1107. The meters can be used for currents up to 100 A.

The meter is equipped with features to enable the detection of fraud attempts. The meter has a reverse energy register as well as a register recording the number of power-on hours it sees.

A unique feature is the low power consumption which helps to reduce the network losses

Modular design

The meter fulfils the requirements of today’s metering practice, while the design concept is already prepared to cope with tomorrow’s needs in a fully liberalised market. Future requirements can be realised in the form of external circuits incorporated in a module unit that can be adapted to the basic meter (adaptive meter concept).

1.2Technical Data

1.2.1 Voltage Values

Rated Voltage
•	Nominal as per IEC 61036....................................................	230V + 10%
•	Range for mains input voltages .................................	0.8 up to 1.15 x Un

Note:

1.The meter is fully operational within 4 seconds of the application of a voltage supply in the above range

2.The meter will power down and inhibit all operations if the mains voltage falls below 150VAC.

3.Between ISO V and 184 V operation is not guaranteed, however the meter will not malfunction, corrupt stored data or register spurious consumption and will power up or down cleanly once the mains input voltage rises above or below these values.

4.The requirements specified in 2 and 4 above, are independent of the rate of change of the mains input voltage.

5.The meter will remain operational for mains voltage interruptions of up to 0.2 seconds. For interruptions of greater than 0.2 seconds, the meter may power down and up again but shall do so without malfunction, corrupting data or registering spurious electricity consumption.

1.2.2 Current Values

Basic current Ib ................................................................	either 10A or 20A
Maximum Current Imax..................................................	either 80A or 100A
Maximum measuring range ...........	up to 120A without exceeding 5% error
Creep inhibit circuit operating ...............................	at approximately 40mA

Note: Current sensing is by means of a shunt.
