Installation

Disconnect power prior to installation.

Reinstall any covers that are displaced during the installation before powering the unit.

Mount the meter in an appropriate electrical enclosure near equipment to be monitored.

Do not install on the load side of a Variable Frequency Drive (VFD), aka Variable Speed Drive (VSD) or Adjustable Frequency Drive (AFD).

The meter can be mounted in two ways: on standard 35 mm DIN rail or screw-mounted to the interior surface of the enclosure.

A. DIN Rail Mounting

1. Attach the mounting clips to the underside of the housing by sliding them into the slots from the inside. The stopping pegs must face the housing, and the outside edge of the clip must be ush with the outside edge of the housing.

2. Snap the clips onto the DIN rail. See the diagram of the underside of the housing (below).

Clip ﬂush with outside edge

The E51Hx power meters have a number of dierent possible system wiring congurations (see Wiring Diagrams, page 5). To congure the meter, set the System Type via the User Interface or by writing the Present_Value of AV2 with the System Type value in the table below. The System Type tells the meter which of its current and voltage inputs are valid, which are to be ignored, and if neutral is connected. Setting the correct System Type prevents unwanted energy accumulation on unused inputs, selects the formula to calculate the Theoretical Maximum System Power, and determines which phase loss algorithm is to be used. The phase loss algorithm is congured as a percent of the Line-to-Line System Voltage (except when in System Type 10) and also calculates the expected Line to Neutral voltages for system types that have Neutral (12 & 40).

Values that are not valid in a particular System Type will display as “----” on the User Interface or as QNAN in the BACnet objects.

Fuse Recommendations

Keep the fuses close to the power source (obey local and national code requirements).

For selecting fuses and circuit breakers, use the following criteria:

• Select current interrupt capacity based on the installation category and fault current capability.

• Select over-current protection with a time delay.

• Select a voltage rating sucient for the input voltage applied.

• Provide overcurrent protection and disconnecting means to protect the wiring. For AC installations, use Veris AH02,

AH03, AH04, or equivalent. For DC installations, provide external circuit protection. Suggested: 0.5 A, time delay fuses.

• The earth connection (G) is required for electromagnetic compatibility (EMC) and is not a protective earth ground.

For system type 1+N (10), this is a Line to Neutral Voltage, indicated by “V LN”. Note: the meter will reject settings that are not within the meter’s operating range when divided by the PT ratio.

System Power: MX KW – The theoretical Maximum System Power is calculated by the

meter from the System Voltage, CT size, and System Type. Power Factor is assumed to be unity. The value of System Power is used to determine which combinations of pulse weight and duration are valid and will keep up with the maximum power the meter will see. This value is read only.

BACnet Programming Information

The E51Hx is programmable via BACnet protocol and can easily be connected to a BACnet MS/TP network using an o-the shelf BACnet router. It uses ve types of BACnet objects. A standard PICS (below) describes the required characteristics of the BACnet implementation, but this additional descriptive context may be helpful to the integrator.

In addition to the required properties, the device object utilizes some optional properties to support other functionality, Time Synchronization (primarily used for data/trend logging on the device) and Description and Location properties to simplify installation and maintenance. Congure all of the meter’s functions, other than Data Logging and writable Device Properties, by writing the Present_Value of the 11 Analog_Value objects. These values (except for the conguration register, AV1, which always returns zero when read) are all readable and stored in nonvolatile memor y so that they are retained if power to the device is interrupted.

Data values other than log information and alerts are all accessed by reading the Present_Value of the 52 Analog_Input objects. Most of these values are instantaneous readings of measured service parameters. Some of them, (AI1-AI10, AI22-AI27, AI31-AI54, AI76-AI78) represent accumulated values and are stored in nonvolatile memory as well. If power to the device is interrupted, these values are retained, but no additional information accumulates until the device completes its re-initialization.

Alerts are used to indicate conditions of potential concern to the installer or the system, such as input voltage or current on any phase that exceeds the meter’s measurement range, phase voltage below the Phase Loss Threshold set by the user, or Power Factor below 0.5 on any phase. Alerts are accessible individually by reading the Present_Value of the Binary_Input objec ts or as a group by reading the Present_Value of Analog_Input object 52. Alerts are not latched and do not generate events to system. They indicate presence of these conditions at the time they are read, but the device does not latch and store them until they are read (if the condition changes before they are read, the alert will go away).

All Analog_Value, Analog_Input, and Binary_Input objects implement the reliability property and use it to indicate that the Present_Value properties are functional, valid and current. For complete assurance, check the Reliabilty property for a No_Fault_ Detected status before reading the Present_Value of any AV, AI or BI objec ts.

The E51H5 includes data logging capability, which is implemented using three Trend_Log objects. These are described in more detail in the section on data logging.

Analog_Value Objects

Use the Present_Value property of the Analog_Value object for all writable variables in the meter other than those used specically for BACnet conguration, Time Synchronization (in the Device Object), or Data Logging (in the Trend_Log objects).

Values are checked when writ ten, and errors are returned for invalid entries. This table describes how the meter uses those variables, what values are valid, and what their defaults are. When writing values to the Present_Value properties of Analog_ Value BACnet objects, there is a delay of up to about two seconds to validate and store the new value. An immediate read of the same property before that delay has elapsed can return the prior value (even if the new value was accepted). To read a value immediately after writing it, check the Reliability property rst. When it reports a No_Fault_Detected status, the Present_Value of the object is current.

These objects support the Description and Reliability object properties and all required Analog_Value object properties, but Present_Value is the only writable property.

Any phase (as congured in AV2) whose level drops below this threshold triggers a Phase Loss alert - i.e. if the System voltage is set to 480 V L-L, the L-N voltage for each phase should be 277 V. When the threshold is set to 10%, if any phase drops more than 10% below 277 V, (less than 249 V), or if any L-L voltage drops more than 10% below 480 V (less than 432 V) the corresponding phase loss alarm bit will be true.

For a 3-phase Y (3 + N) system type (40 in object AV2), both Line to Neutral and Line to Line voltages are tested. In a 3-phase ∆ System type (31 in object AV2), only Line to Line voltages are examined. In a single split-phase (2 + N) system type (12 in object AV2), only the line to neutral voltage are compared.

manual triggerring of demand intervals and the logging of another Trend_Log record, set this value to 0 and write 21211 to the reset register (object AV1) each time the sub-interval must be externally reset. Default is 90000 (15 minutes). This variable is tied directly to the Log_Interval property of all three Trend_Log objects (their value is always the same as this one). Changing any of these four properties changes all of them.

Trend_Log values are only used on the E51H5 model.

Analog_Input Objects

Use the Present_Value property of the Analog_Input objects for all read-only numeric variables in the meter other than those used specically for device conguration (in the Device Object) or data logging (in the Trend_Log objects). Only the E51H5 supports the data logging capability.

These objects support the Description and Reliability object properties and all required Analog_Input object properties. None of them are writable. The values that are not instantaneous (i.e., Accumulated Energy, Max Demand, Pulse Input Counts) are non-volatile. They are not updated while control power is inactive, but their past values are retained when power is restored. The Present_Value of the accumulated data objects (AI1-AI10 and AI31-AI54) use oating-point data types (all AI objects use oating point data points). The resolution of the accumulated values decreases as the value grows larger over time and more of the signicant digits precede the decimal point. If the size of the value limits the resolution unacceptably, read and store the current value oine and reset the accumulators to restore ner resolution.

For complete assurance, check the Reliabilty property for a No_Fault_Detected status before reading the Present_Value. If the line voltage or input frequency of the system being monitored falls out of the supported range, the corresponding alert bits (BI1-BI7) are set and the reliability property of any values that cannot be accurately measured under those conditions returns Unreliable_Other.

Binary_Input Objects

Use the Present_Value properties of the Binary_Input objects as alerts for conditions of potential concern regarding to the system measurement. These values are dynamic and are not latched, so if the condition is resolved, the alert will go inactive, whether it has been read or not.

These objects support the Description and Reliability object properties and all required Binary_Input object properties. None of them are writable. For complete assurance, check the Reliabilty property for a No_Fault_Detected status before reading the Present_Value.

To test the meter’s alert status, read the Present_Value of each of the Binary_Input objects representing the alert bits of interest, or read the Present_Value of AI52, which combines all 15 bits into a single decimal value. AI52 represents the status of all 15 Binary_Object alert values in one number that can be read without having to access mulitple objects. The bit value of Object BI1 is the least signicant bit and BI15 is the most signicant bit (BI15 is only present on the E51H5).

Data Logging (EH Only)

The E51H5 includes a data logging feature that records three meter parameters, accessible via BACnet using Trend_Log objects. All three Trend_Log objects utilize shared data logging resources in the meter, so all three are controlled in unison. All writable properties other than Log_Device_Property_Object are common to all three Trend_Log obects. Changes to these properties (Log_Enable, Start_Time, Stop_Time, Log_Interval, Stop_When_Full or Record Count) for any one of the objects will be reected in the corresponding property of all three objects. The Log_Interval property is also common with the Demand_Subinterval (Present_Value of AV11), since logging records are updated synchronously with demand calculations.

Default settings cause logging to begin immediately, with 15 minute intervals and no stop time. When full, the buer will wrap and overwrite the oldest data rst (unless the Stop_When_Full property is used).

Conﬁguration

Use Log_Device_Object_Property to select the meter parameter to log with each object. Set this property to point to Present_ Value property of any of the Analog_Input objects. The default the values for the Log_Device_Object_Property of the three Trend_Log objects are set as follows:

• TL1 = Real Energy Import (AI2 Present_Value)

• TL2 = Real Energy Expor t (AI3 Present_Value)

• TL3 = Total Real Power Present Demand (AI19 Present_Value)

The Log_Interval (& Demand Subinterval) can be set from 10 seconds to 32767 seconds (values of 1000 to 3276700). The subinterval timer, which determines how often the meter’s demand accumulators are updated, also triggers writing to the Trend_Log log buers. Use the Log_Interval property to set the data logging time subinterval, in units of hundredths of a second (0.01 seconds). The default subinterval is 15 minutes (a value of 90000 in the Log_Interval property). The Buer_Length is xed at 5760, so at a 15 minute interval setting, the buers hold 60 days of data.

Use the Stop_When_Full property to select either Single Shot (Stop_When_Full = TRUE) or Continuous mode (Stop_When_Full = FALSE) for data logging. The default mode is Continuous. In Single Shot mode, the meter records data only until the buer is full. Data for this time period is kept, but newer energy information is lost. In Continuous mode, the meter continues to record energy data as long as the meter is operating. The buer can only hold 5760 entries at one time, however, so when the number of records exceeds 5760, the oldest entry is deleted to make room for the newest.

To start data logging with any of the three Trend_Log objects, set the Log_Enable property to TRUE or set the Start_Time and Stop_Time properties appropriately and wait for logging to commence at Star t_Time.

By default, the Record_Count property of the Trend_Log objects is initialized to Zero.

Reading Data

Access logged data with corresponding timestamps via the Log_Buer property of the Trend_Log object using the BACnet ReadRange service. The E51H5 supports both the “by Position” and “by Sequence Number” modes of the ReadRange service, but not the “by Time” mode.
