6AS302P Single Phase Smart Meter
____________________________________________________________________
©Honeywell -M450 001 1D -23.05.2019
WARNINGS (continued)
Removal of Covers
All supplies connected to the meter must be isolated before any attempt is made to remove the meter terminal cover.
Failure to do so may result in electric shock or death.
Live parts will be exposed when the terminal cover or main cover is removed.
Removal of the communications module is permissible whilst the meter is still energised.
Removal of the main cover invalidates the certification of certified meters.
Liquid Crystal Display
Liquid crystals are toxic. If a display is damaged, avoid contact with the liquid. If the liquid makes contact with the skin
it must be washed off immediately with water.
Seek medical advice.
Batteries
The meter contains an internal 3.0V Lithium Coin Cell.
This battery is completely safe under normal conditions. However, it must never be recharged, disassembled, short-
circuited, heated above 100°C, incinerated, or have the contents exposed to water.
Fire, explosion or severe burns may result if these instructions are disregarded.
In the interests of safety, environmental protection and relevant legislation, Lithium batteries require careful disposal.
Before arranging for the disposal of these cells, users should satisfy themselves that the proposed means of disposal is
both safe and compliant with local legislation requirements.
Honeywell would like to draw the user's attention to the International Standard for Lithium Batteries - IEC 60086-4 -
which gives further information about the handling, storage, transport and disposal of lithium cells.
Honeywell should be contacted by the user should difficulties arise in arranging proper disposal. They will if practical
help the user identify safe disposal means.
Transferring Meters from Cold to Humid Conditions
The AS302P meter can be safely stored in the temperature range of -25C to +70C.
However a sudden change in temperature can cause condensation which if present can compromise the safety and
operation of the meter.
On installation, a meter that has been stored in cold conditions should be removed from its packing and acclimatised at
site temperature for at least one hour before connecting to the mains supply to allow all traces of condensation to
evaporate.
Auxiliary Relay
The 230V a.c. relay current must not exceed 2A.
The installer is responsible for the type and gauge of cable used and must ensure the cable is protected by a suitable
fuse (≤ 2A).
All supplies connected to the meter must be isolated before connecting the cable.

The Main Cover is secured by two screws (shear head)
A separate sealable screw secures the Terminal Cover.
A separate sealable screw secures the Comms Hub.
The Outline and Fixing Dimensions are shown in 34.5.
6.6. Unauthorised Physical Access (Tamper Detection)
If a Tamper Event is detected the meter can be configured to open the Main Contactor. In this event the contactor can only
be closed again by a Command from DCC.
Communications Hub Removal Detection
Pins are provided on the Comms Hub or in the ICHI Blanking Plate that allow the meter to electronically detect if the
Comms Hub is present or not.
The Removal of a Comms Hub event is stored in the Security Log with a Time and Date Stamp.
Magnetic Field Detection
The AS302P has a sensor which detects if a Strong Magnetic Field has been detected or removed.
The detection or removal of a Magnetic Field is logged in the Security Log with a Time and Date Stamp.
Detection Level of a Magnetic Field (three planes) is:
Range 25 to 60 Gauss (2.5 to 6.0 milli-Tesla).
When there is no power to the meter, only the first tamper event will be recorded:
Main Cover and Terminal Cover Removal Detection
The Main Cover and Terminal Cover are fitted with Tamper Switches to detect removal.
The Removal of a Cover Event is stored in the Security Log with a Time and Date Stamp.
7. TEST OUTPUT DEVICES & ANTI CREEP INDICATION

8. FEATURES
The meter contains numerous features; combinations of which can be selected to provide the required metering function.
The meter stores 4 types of data:
•Operational Data (See Appendix D for details) - Created/updated by the meter, this can be read by the DCC at
any time.
- It is expected that data read from the meter should be verified in the Suppliers backend system e.g. to
ensure cumulative registers have advanced etc.
•Configuration Data (See Appendix D for details) - Can be read and configured by the DCC at any time
- If this data is configured then an event is stored in the Event Log with a Time and Date Stamp
•Constant Data (See Appendix D for details) - configured during manufacture and can be read by the DCC at any
time
•Internal Data (See Appendix D for details) –this data is not available outside the meter
8.1. Registration of Quantities
kWh (Active Energy)
•kWh Import (+A)
•kWh Export (-A)
kvarh (Reactive Energy)
•kvarh Import Reactive (+R)
•kvarh Export Reactive (-R)
kvarh is derived using the phase shift method.
The resolution of registration is 0.001kWh (kvarh).
Total Import and Export Quantities are registered separately.
The measurement discrimination is such that as the power
factor of any load from 0.05Ib to Imax is varied over 360°, the
import and export registers will never advance together.
Note: The diagram shows a representation of the quadrants. The quadrant of the present load can be shown on the
display.
8.2. Demand Registers
A Demand Register is associated with the Import and Export kWh Registers.
The Demand Period is set at 30 minutes.

9. OPERATING MODES
The AS302P can be configured to operate in Credit or Prepayment Mode. If no parameters are sent the meter will remain
as programmed during Manufacture. The following mode switching configurations are available:
Credit to Prepayment
Prepayment to Credit
Credit to Credit
Prepayment to Prepayment
The mode of operation is available on the display and through the HAN for other devices.
9.1. Change of Operating Mode
On any change of mode the following actions occur:
•A Set of Billing Data is Recorded
•The Time and Date is Recorded
•The Meter Balance is Set to Zero
Credit Mode to Prepayment Mode (or Credit to Credit)
•As above.
Prepayment to Credit Mode (or Prepayment to Prepayment)
•As above
•Prepayment Billing Information is recorded
GBCS Use Case ECS03 “Set ESME Payment Mode to Prepayment” is used to switch the Meter to Prepayment mode. On
using this use case the following parameters are configured in the meter:
•New account in Prepayment mode
•Disablement threshold
•Suspend Debt Disabled and Suspend Debt Emergency
•Activation time for the new account, Disablement Threshold and Suspend Debt Disabled / Emergency
parameters
GBCS Use Case ECS02 “Set ESME Payment Mode to Credit”is used to switch the Meter to Credit mode. On using this
use case the following parameters are configured in the meter:
•New account in Credit mode
•Suspend Debt Disabled and Suspend Debt Emergency –Note: these are not actually used in credit mode
•Activation time for the new account and Suspend Debt Disabled / Emergency parameters
10.CHANGE OF SUPPLIER AND TENANCY
The AS302P can be programmed with an Activation Time/Date for a New Supplier or a New Tenant (Restrict Data). This
will be actioned by a command from DCC.
10.1. Contact Details
Name and Phone Number for the Supplier is available on the Meter Display and can be configured as follows:
•Supplier Details –15 characters
•Supplier Phone Number –18 characters

10.2. Restrict Data
A dedicated Restriction of Data Notification Command is used to restrict the data made available on the display and to
Type 1 & Type 2 Devices. This command will contain a date from which the data is restricted (this date can be in the past).
All data will still be available to read via the DCC.
11.TARIFF
11.1. Deferred (Pending) Tariff
There is a Command from DCC to set a Tariff on the meter.
This will contain the following information:
•Tariff TOU Price Matrix (at least one has to be populated)
•Tariff Block Price Matrix,
•Tariff Switching Table
•Tariff Thresholds
•Standing Charge
•Currency Units (£ or €)
The Tariff previously set in the meter will continue to be used until the newly downloaded tariff is activated.
Each of these items can have their own Activation Date/Time. If an Activation Date/Time is set in the past, this will be
actioned immediately. It is possible for an Activation Date/Time to be set significantly far enough in the future so that any
new tariff element will never be activated.
A Cancellation Command can be sent to prevent any part of the tariff becoming active.
When the meter changes its tariff structure then Billing Data is captured. If in Prepayment Mode, Billing and Prepayment
Data will be captured.
11.2. Tariff Structure
The meter can operate in either TOU Mode or TOU Block Mode.
Switching times on the TOU can be subject to a Randomisation Offset. This is based on:
- Randomised Offset Limit (A value in seconds in the range 0 to 1799)
- Randomised Offset Number (A randomly generated value between 0 and 1)
11.2.1. TOU Mode
Independent Switching for 48 TOU Registers based on Imp KWh.
