The meter complies with Class M2 Mechanical environment and Class E2 Electromagnetic Environment as defined in the Measuring Instruments Directive 2014/32/EU. The AS302P meter has been designed and manufactured to comply with the relevant requirements of the following Directives and Specifications.
This Manual covers the features of the AS302P SMETS2 product. The SMETS2 meter is designed specifically for the UK market and conforms to all DECC published requirements (GBCS V1.1, SMETS2 v2.0). The AS302P is a Multi-tariff Residential Smart Meter that can be programmed by the Supplier to operate as a Credit or Prepayment Meter.
Import (+R) kvarh Export (-R) 6.4. Meter Accuracy The AS302P meter measures Active Energy, in accordance with the requirements of: • EU Directive 2014/32/EU (MID) - Class A or Class B (EN 50470-1, EN 50470-3) The meter measures Reactive Energy in accordance of the requirements of: •...
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.
AS302P Single Phase Smart Meter ____________________________________________________________________ 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...
Type 1 or Type 2 Devices. Price Information is also used for the Prepayment Application and to calculate Cost Information. The AS302P contains the ‘Active’ and a ‘Deferred’ Price Matrix which must be configured for each TOU Rate. The Price Matrix is for Import Active Energy only.
The TOU Block Price Matrix can be programmed to be activated at a specified Activation Date/Time. The TOU Block Price Matrix for the TOU Block Tariff is shown below: 11.3.2. Maximum Demands The AS302P calculates and stores the following Maximum Demands: • Maximum Demand Active Power Import Value •...
AS302P Single Phase Smart Meter ____________________________________________________________________ 13. CUSTOMER COST INFORMATION 13.1. Consumption Data The AS302P stores the following data for Daily, Weekly and Monthly Billing: • Import kWh • Estimated Cost for kWh Import Daily Cost is calculated by taking the advance in each TOU or TOU Block Register and multiplying this by the Current Price plus Standing Charge.
An event will be created in the Event Log (with appropriate code) when the PIN is disabled or changed via the Pushbuttons. Honeywell suggests that the Utility providing the meter includes in its User Guide advice on: selection, secure handling or entry of the user PIN.
21.2. Direct Communications Connection to the Comms Hub The Comms Hub Interface allows provision for a Hardwired Interface between the Meter and the Module. This feature is not supported by the AS302P meter. 21.3. HAN Communications Connections to the Comms Hub The meter provides a HAN Interface that conforms to the following standards: ZigBee Alliance as compliant with the ZigBee SEP v1.2b...
AS302P Single Phase Smart Meter ____________________________________________________________________ • On joining a ZigBee SEP v1.2 Smart Metering Home Area Network, the AS302P is capable of generating and sending an Alert to that effect via its HAN Interface. • Restricting Personal Data Available for Type 1 and Type 2 Devices from a defined UTC Date and Time •...
The Comms Hub notifies the AS302P that a New Firmware Image is available • The AS302P downloads the new Image, via the ZigBee OTA process, when it is aware of the availability of a suitable Upgrade Image 22.3.2. Verification of the Image •...
• The AS302P verifies its Firmware at every Power On to check that it is the same as the last Verified and Running Firmware. If the verification fails then an entry in the Security Log will be made and an Alert will be generated on the HAN.
25. CONTACTOR A single pole, 100A Contactor is provided in the AS302P. Contactor Technical Details are given in Section 29.2. Note that in normal use, the user can Enable the Supply if the Contactor state is Ready for connection (Armed) using the meter display.
__________________________________________________________________________ 26. INTERNAL CLOCK The AS302P compares its Time with the Comms Hub and adjusts as necessary. No event is recorded, providing the time difference is no greater than 10s. If the Time Difference is greater than 10s then the meter does not adjust its time but generates an Event in the Security Log and sends an Alert over the HAN.
(based on the command outcome). 27.2. Security Credentials The AS302P generates Public-Private Keys to support Cryptographic Algorithms, initiated by a Command. These are the Device, Signing and Key Agreement Certificates. Once a device has been installed then the Supplier should send an ‘Issue Security Credentials Command’ to the meter within seven days of installation.
The Meter employs techniques to protect against Replay Attacks, on any communications. 27.6. Security Log The AS302P has a Security Log to store any Security Related Events (See Section 28), this Log cannot be cleared unless the Physical Boundary is breached.
AS302P Single Phase Smart Meter ____________________________________________________________________ 28. METER LOGS The AS302P stores a number of Event Logs to record events that have occurred in the Metering Device. These Logs are: • Security Log • Event Log • Power Quality Log All Logs are stored on a FIFO basis and each event is stored with a UTC Date and Time Stamp.
HHT needs a robust connection to Suppliers Systems to make the Installation Viable due to sequencing of Commands and Responses – The AS302P is likely to remain on its Own Time (from factory) but identified in GBCS terms as “Unreliable” until a Comms Hub WAN connection is established –...
31.5. Electromagnetic Compatibility (EMC) The AS302P meter has been designed and tested for compliance with the EMC Directive. It is, however, the responsibility of the installer for ensuring that a system conforms to the Directive.
26mm. The terminal block dimensions on the AS302P meter have a maximum sectional area of 50mm Fully insert cables into the terminals so that the insulation butts up into the counter-sunk recesses in the bottom face of the terminal block.
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.
Various methods of checking the accuracy of registration of the AS302P meter are available. Methods using the LED test indicator and Register advances are described below. Note: The AS302P meter does not have potential disconnect links. Where multiple meters are to be tested, a multi- secondary voltage transformer will be required.
