10. Operation

The following describes how to navigate through the various menus and submenus.

10.1. Main Menu Pages

After the power supply is initially connected , the test screen appears first. After about two seconds, the "Active Energy Import" main menu page is displayed.

Each time you press the Right Arrow button, you navigate through the various main menu pages.

By pressing and holding the "Right Arrow" button for more than 2 seconds, you can also scroll backward through the circular menu (firmware version 1.3.0 or later).

10.2. Submenu Pages

The available submenu pages are described below.

Energy Displays

The main menu pages for Active Energy Import/Export and Reactive Energy Import/Export display the total energy consumption or total energy supplied, respectively. By default, the following schema is used for the submenu pages:

To ensure the most accurate display of energy values possible, the Hyperion features an autorange function. If the displayable range is exceeded, the message OF appears on the display. The registers that can be read via the communication interfaces only overflow at significantly higher values (approx. 18 billion GWh) than the display (99 million MWh).

The energy values are shown on the display according to the following scaling:

Maximum energy register value: 18,446, 744,073,709,600,000 Wh = 18,446.7 PWh

10.3. Power and Electricity Consumption

The main menu pages "Active Power," "Reactive Power," and "Apparent Power " each display the current total power across all three phases.

Use the Down Arrow key to switch between the power values of the individual phases.

On the Current main menu page, the total current of all three phases is displayed by default. Use the Down Arrow key to view the current values for the individual phases.

The four-quadrant diagram shows the relationship between positive and negative active and reactive power. When active power is negative, the displayed current is also shown as negative. In addition , the energy directions (P>>, Q>> etc.) are displayed.

Quadrant I

• Positive active power; active energy reference register is incremented.
• Reactive power is positive; the reactive energy consumption register is incremented.

Quadrant II

• Active power is negative; the active energy delivery register is incremented.
• Reactive power is positive; the reactive energy delivery register is incremented.

Quadrant III

• Active power is negative; the active energy consumption register is incremented.
• Reactive power is negative; the reactive energy consumption register is incremented.

Quadrant IV

• Active power is positive; active energy consumption register is increased.
• Reactive power is negative, reactive energy consumption register is increased.

10.4. Voltage, Power Factor, and Frequency

These menu pages display the current values for voltage, power factor, and frequency. The display is updated every second.

13. 4. Error Cases

If you detect an error with the Hyperion, first consult the following information on the most common error patterns.

Discrepancies in Energy Measurement by the Hyperion Energy Meter

Initial Situation: One or more phase currents are displayed with a negative sign .

Solution: Check whether the connections S1 ↑ and S2 ↓ (for direct-connection meters: Lx ↑ and Lx ↓) are connected correctly.

S1 ↑ or Lx ↑ must always be connected to the utility side . S2 ↓ or Lx ↓ must always be connected to the load or generation side.

The meter is measuring too much or too little energy

Solution 1: Check the set current transformer and voltage transformer ratios. The settings must correspond to the transformers actually in use.

Solution 2: Check that the meter is wired correctly. Phases with negative current flow are assigned to the export register.

Incorrect consumption display for transformer-based meters

Initial : The Hyperion displays a significantly higher or lower consumption than expected.

Solution: Ensure that the set current transformer ratio matches the current transformer actually in use.

The current transformer ratio can be configured directly using the Hyperion's control buttons.

• 5 / 5 A to 20,000 / 5 A in 5-A increments
• 1 / 1 A to 4,000 / 1 A in 1-A increments

Incorrect consumption display in single-phase operating mode

Initial situation: The Hyperion is counting incorrectly or the energy meter reading is not increasing during single-phase operation.

Solution: Check the wiring diagram for single-phase operation as described in Chapter 9.5.

Behavior for Consumption and Delivery

The Hyperion stores energy consumption and energy delivery in separate registers.

The register values are never counted backward or offset against each other.

The register Active Energy Consumption contains the electrical energy consumed from the utility and forms the basis for energy consumption.

The register Active Energy Supplied contains the energy fed into the grid, for example from a photovoltaic system.

Example:

Current consumption of a residential complex at 1:00 p.m.:

• Phase L1: 10 kW
• Phase L2: 20 kW
• Phase L3: 30 kW

Total consumption: 60 kW

Feed-in from the photovoltaic system at 1:00 p.m.

• Phase L1: 25 kW
• Phase L2: 25 kW
• Phase L3: 25 kW

Total feed-in: 75 kW

In this case, 15 kW is currently being fed into the grid.

The Active Energy Consumption register remains unchanged for phases L1 and L2, since no energy is being drawn from the grid.

The Active Energy Supply register is increased for phases L1 and L2, since energy is being fed back into the grid there.

Phase L3 . Therefore, the Active Energy Supplied register for L3 remains unchanged, while the Active Energy Consumed register is further increased.

The Hyperion is supplying incorrect values via the pulse output

Check whether the configured pulse rate and pulse duration of the Hyperion energy meter match the specifications of your pulse receiver.

The pulse rate and pulse duration can be adjusted directly using the Hyperion's control buttons.

Available settings:

• Pulse rates: 1, 10, 100, 1000, or 10,000 pulses per kWh / kvarh
• Pulse widths: 2 ms, 10 ms, 30 ms, 40 ms, or 120 ms

The following values are set at the factory:

The tariff switching is not working

Tariff 1 is enabled by default. Check whether the tariff switching has been connected correctly.

The LoRaWAN® communication interface is not working

• Make sure that the meter is registered on your LoRaWAN® network server.
• Check whether the set LoRaWAN® transmission interval matches the available network bandwidth. A high number of end devices on the same network can impair communication.
• Ensure that the meter can synchronize its time via the LoRaWAN® network.

14. Advanced Information on Load Profiles According to PTB-A 50.7

14.1. Measurement Accuracy Guidelines: Requirements for Users Pursuant to Section 23 of the and Calibration Ordinance

The Measurement and Calibration Ordinance requires all users of measuring instruments to conduct measurements and operate measuring instruments in such a manner that the accuracy of the measurement results is guaranteed.

Taking into account the market roles under the Metering Point Operation Act, a distinction is made between the following groups:

• Meter Users
  • Meter users are metering point operators as defined by the Metering Point Operation Act.
• Measurement Value Users
  • Measurement value users are individuals or organizations that record measurements, pass on measurement values to authorized third parties, and handle billing for energy supply and grid usage.

Metering device users are obligated to ensure that measurement value users are made aware of the following requirements.

Transparency of Use

The measurement value user must be able to clearly explain to electricity customers how the billed active energy and, if applicable, reactive energy values are calculated.

Transparency means that customers can understand the items on their electricity bill using the meter readings relevant under metrology law.

In particular, the following information must be provided:

• Which displayed measurement values may be used for billing purposes.
• That values not displayed may not be used for billing purposes.
• That displayed values originating from functions not relevant to metrology serve exclusively for informational purposes and may not be used for billing.

In addition, the devices must be used in such a way so that electricity customers can clearly read both the meter readings relevant for billing and any error messages at any time.

Tariffing

For the use of meter reading sequences in compliance with metrology laws, only the tariffs T1 and T2 may be used.

In doing so, the requirements of § 33 MessEG must be observed.

The user of the meter readings must ensure that invoices, insofar as they are based on meter readings, can be easily understood and verified by the invoice recipients. If necessary, suitable tools must be provided for this purpose.

It must be ensured at all times that all registers used for billing are also displayed on the meter's screen.

14.2. Error Messages / Time Adjustments

Error Messages

The accompanying documents describe the device malfunctions that can be themselves. 14.2. Error Messages / Time Adjustments Error Messages The accompanying documentation describes the device malfunctions that can be detected and displayed by the meters themselves. If one or more of the events designated as "metering-law

If one or more of the events designated as "metering-law-relevant error messages" occur, the device's compliance with metering laws is no longer guaranteed. In this case, the stored measurement values must be considered unreliable.

The affected devices must be removed, repaired if necessary, and re-calibrated, provided they are to continue to be used for billing purposes.

Time Adjustment

For meters with a remotely controllable internal clock, technical measures must ensure that any change to the time relevant to measurement and billing accuracy can be traced.

For Hyperion meters, this is implemented as follows :

• Any change to the meter clock via one of the available communication interfaces generates an entry in the calibration log.
• The recording period in progress at the time of the time change is marked as invalid.
• The recording period restarted after the time change ends at the next integer multiple of the set registration period length—for example, at minute 00, 15, 30, or 45, relative to the newly set time.

Use of Communication Interfaces

The meters' communication interfaces do not comply with metrology regulations.

Measurement values read via these interfaces may be used for billing purposes only to the extent that to the extent that they represent an unchanged repetition of the measurement results displayed on the screen. The provisions of the Measurement and Calibration Ordinance, Annex 2, Section 8.1, are decisive in this regard.

Time Synchronization

The meters mentioned can be synchronized via the existing communication interfaces.

To ensure that meter reading procedures meter reading transactions, the operator must ensure that the meter's internal clock is synchronized with the legal time.

Before transmitting the date and time, the specified prerequisites must be met:

• The M-Bus must be available for communication.
• The Ethernet connection must be available for communication.
• Legal time must be used as the time source.

If these requirements cannot be met, the meter reading operations must not be used for billing-related purposes.

Measurement results that must not be used for billing purposes

Measurement values other than those listed in the type examination certificate may not be used for billing purposes.

Logbook Function

The meters mentioned have a metrological logbook. This can only be deleted by bypassing the manufacturer's access protection.

Hyperion

The following describes the menu items of the Hyperion energy meter relevant to load profile operation.

The load profile of the Hyperion energy meter is certified according to PTB-A 50.7. For the LP version of the Hyperion energy meter, the following information applies regarding tariff switching, time synchronization, transformer parameters, and the S0 pulse output.

Current and Voltage Transformer Ratios

The set current and voltage transformer ratios determine the factor applied when measuring energy quantities. The values must be set according to the current and voltage transformers used.

Changes to the current transformer and voltage transformer ratios can only be made using the SRVC button. The SRVC button can be secured against unauthorized access with a seal.

Real-time clock

The real-time clock displays the currently valid device time.

If automatic time synchronization , the use of UTC time is recommended, as automatic daylight saving time adjustment is not supported.

Changes to the real-time clock can be made using the SRVC button. The SRVC button can be secured against unauthorized changes with a seal.

S0 Pulse Output

The S0 pulse output can be configured for different types of energy:

• Active energy diff: All active energy, regardless of whether it is consumption or supply, is output together.
• Reactive energy diff: All reactive energy, regardless whether it is consumption or supply, is output together.
• Active Energy Import: Only consumed active energy is output via the S0 output.
• Reactive Energy Import: Only consumed reactive energy is output via the S0 output.
• Active Energy Export: Only supplied active energy is output via the S0 output.
• Reactive Energy Export: Only supplied reactive energy is output via the S0 output.

The S0 output generates an electrical pulse for the set amount of energy. These pulses can be used to calculate the amount of energy transmitted.

The following parameters can be configured:

• Pulse value: Number of pulses output per unit of energy.
• Pulse duration: Duration of a single pulse.

The settings for the S0 pulse output can be changed only using the SRVC button.

The SRVC button can be protected against unauthorized changes by means of a seal.

Use for Billing Purposes

For the LP version of the Hyperion energy meter, only active energy measurements are approved for billing purposes.

These readings can be retrieved at any time via the display or the respective device interface.

All other measured values shown on the display are for informational purposes only and must not be used for billing purposes.

This also applies to measured values that can only be read via interfaces and are not shown on the display.

Description

The load profile function according to PTB-A 50.7 consists of two subfunctions:

• Load Profile Memory
  The load profile memory records measured values and is designed as a circular buffer. Once the maximum storage capacity is reached, the oldest entries are overwritten. For technical reasons, overwriting occurs in groups of 27 data records each.
• Logbook Memory (Metrological Logbook)
  The logbook documents all changes to parameters that affect the load profile recording.

The logbook memory cannot be tampered with without damaging the existing seals.

The following changes are logged:

• Changes to the date and time
• Changes to the voltage transformer or current transformer ratio
• Changes to the S0 pulse polarity
• Changes to the S0 pulse duration

Within a load profile interval, each of these parameters can be changed only once. Further changes are possible only after the start of the next recording interval.

The logbook has a maximum capacity of 2,048 entries. These entries cannot be deleted or overwritten.

If the storage capacity is exhausted and a further change is subsequently made to one of the logged parameters, the meter enters a state that is invalid under metrology regulations.

This is indicated by the symbol PTB NV on the display. In addition, all subsequent load profile entries are assigned the status NG (invalid).

Recording Interval

The load profile recording interval is fixed at 15 minutes for the LP versions of the Hyperion energy meter and cannot be changed.

Time Synchronization

Time synchronization is performed via a defined command using the M-Bus or TCP/ IP interface, via a time server recognized under metrology law that provides legal time, or directly via the meter's control buttons.

In this process, the date and time are transmitted to the meter. Synchronization is performed immediately and, when synchronized via the M-Bus interface, is confirmed with an ACK message.

The time can only be synchronized or set once per 15-minute recording period. Legal time must always be used.

A distinction is made between time synchronization and time setting:

• Time synchronization: Any time setting with a deviation of less than 9 seconds from the previously valid time is considered normal synchronization. In this case, no log entry is created.
• Time setting: If the real-time clock is set for the first time or if the deviation from the previous time exceeds 9 seconds, a log entry is generated and the current load profile is marked with the status NG.

The internal buffer (power reserve) for maintaining the system time during a power outage lasts for at least 18 days, provided the meter has been in operation for at least two hours beforehand.

The messages TNV, TNS or NTP appear on the display. The following figure shows under which conditions these messages are displayed and what effects they have on the validity of the measured values.

Tariff Change

For the LP version (PTB-A 50.7 certified) a tariff change is not applied until the start of a new recording period.

The tariff applied to terminals 9 through 11 at the start of the interval remains valid until at least the start of the next recording period.

For the LP version, only dual-tariff operation is available.

The tariff is switched via the tariff inputs on the back of the meter (terminals 9 through 11).

External Interface Readout

Readouts via the external interface can be used for billing purposes.

The interfaces provide the same billing-relevant information that is also displayed on the device's screen.

Storage Capacity

The internal memory offers the following capacities:

• Continuous load profile recordings: 105,378 entries

With a load profile interval of 15 minutes, this corresponds to a period of approximately three years.

S As soon as the maximum storage capacity is reached, the meter overwrites the oldest entries in batches. In this process, the first 26 entries are deleted and replaced by new data records.

Thus, the most recent 105,352 load profile entries are available at all times, while older data records are lost.

• Logbook entries: 2,048 entries

Every change to the current transformer ratio, the voltage transformer ratio, the real-time clock, or the S0 pulse polarity or pulse length generates an entry in the calibration log.

Once all available log entries have been used up, any further change to one of these parameters puts the Hyperion into a state that is invalid for calibration purposes in accordance with the requirements of PTB-A 50.7. state. The device may no longer be used for billing-related applications and must be replaced.

14.3. Power Outage and Restart

Power Outage

All load profile values are stored at fixed 15-minute intervals, i.e., at XX:00, XX:15, XX:30, and XX:45. After a power outage, recording resumes accordingly.

Example:

• Current time: 7:37 a.m., last saved entry at 7:30 a.m.
• Power outage until 8:12 a.m.
• The next entry is made at 8:15 a.m. and is automatically marked as NG .
• The entries for 7:45 a.m. and 8:00 a.m. are missing.

After every power outage, the first load profile entry is marked with the status NG (not valid).

If the internal power reserve was able to maintain the time during the outage, the subsequent load profile entries are not marked as invalid.

Restart

In rare cases, an internal restart of the meter may occur. In this case, the affected load profile entry is marked with the status NG.

Load Profile Display

When the load profile display is opened, the most recently saved entry is always shown.

If all 105,378 available load profile entries are occupied, Hyperion automatically deletes the oldest 26 entries. The sequential numbering is not reset in the process.

Example:

If a Hyperion has already stored 200,000 load profiles, entry 200,000 is initially displayed when the screen is opened. After scrolling back 105,378 entries, the display jumps back to the most recent data records. In this case, the oldest entries have already been overwritten.

The following information is shown on the display:

• 000003: Index of the displayed entry.
• January 5, 2021 10:45:00: Timestamp of the stored load profile.
• NG: Indicates an invalid load profile entry.
• T1 / T2: Associated rate plan.
• 00000000.0 kWh: Meter reading of the active energy register at the time of recording.

A load profile entry is marked as NG (not valid) if:

• relevant device parameters have been tampered with,
• it is the first load profile after a reboot or power outage,
• no time synchronization has been performed within the last two weeks.

Valid load profile entries are displayed without any additional marking.

Imp / Exp refers to switching between the consumption and supply registers.

By pressing and holding the "Down Arrow" key (> 2 s), you can switch between import (consumption) and export values (delivery).
