NOTICE

The E50H2-T2 DIN rail power meter provides a solution for measuring energy data with a single
device. Inputs include control power, CT, and 3-phase voltage. The E50H2-T2 supports BACnet TP
protocol. The E50H2-T2 has one pulse contact input and a phase loss alarm output. The LCD
screen on the faceplate allows instant output viewing.

The meter is housed in a plastic enclosure suitable for installation on T35 DIN rail according to
EN50022. It can be mounted with any orientation over the entire ambient temperature range,
either on a DIN rail or in a panel. The E50H2-T2 meters are not sensitive to CT orientation,
reducing installation errors.

Warnings, Cautions, and Notices

Safety advisories appear throughout this manual as required. Your personal safety and the
proper operation of this machine depend upon the strict observance of these precautions.

The three types of advisories are defined as follows:

Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, could result in
minor or moderate injury. It could also be used to alert against unsafe practices.

Indicates a situation that could result in equipment or property-damage only
accidents.

Important Environmental Concerns

Scientific research has shown that certain man-made chemicals can affect the earth’s naturally
occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the
identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine,
Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon
(HCFCs). Not all refrigerants containing these compounds have the same potential impact to the
environment. Trane advocates the responsible handling of all refrigerants-including industry
replacements for CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs.

Important Responsible Refrigerant Practices

Trane believes that responsible refrigerant practices are important to the environment, our
customers, and the air conditioning industry. All technicians who handle refrigerants must be
certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth
the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and
the equipment that is used in these service procedures. In addition, some states or municipalities
may have additional requirements that must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.

Read the following guidelines before starting installation.

• Disconnect power prior to installation.

• Reinstall any covers displaced during installation before re-powering unit.

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

• Do not install the load side of a variable frequency drive (VFD).

Mount the meter using one of the following two methods:

1. DIN Rail Mount

a. Attach mounting clips to the underside of housing by sliding them into the slots from the

inside.

NNoottee:: The stopping pegs must face the housing and the outside edge of the clip must be

flush with the outside edge of the housing.

b. Snap the clips onto the DIN rail.

Supported Systems

The E50H2-T2 meter has a number of different possible system wiring configurations (Refer to
the table below and next section, Wiring Diagrams). To configure the meter, set the System Type
via the User Interface or by writing the Present_Value of AV2 with the system type value listed in
the following table. 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 configured as a percent of the Line-to-Line System Voltage (except
when in System Type 10). In addition, it 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
display as ———— on the User Interface or as QQNNAANN in the BACnet objects.

NNoottee:: To avoid distortion, use parallel wires for control power and voltage inputs.

Fuse Recommendations

Keep the fuses close to the power source. 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.

• Use a voltage rating sufficient for the input voltage applied.

• Provide over-current protection and disconnecting means to protect the wiring.

• Use the earth connection (G) for electromagnetic compatibility (EMC), not a protective earth

Notes:

• The voltage and current ratings on the terminals are compliant with the requirements
of the EIA RS-485 communications standard.

• The RS-485 transceivers are ¼ unit load or less.

• RS-485+ has a 47 kΩ pull up to +5V, and RS-485- has a 47 kΩ pull down to
Shield (RS-485 signal ground).

• Wire the RS-485 Bus as a daisy chain from device-to-device, without any stubs.
Use 120 Ω termination resistors at each end of the bus (not included).

• Shield is not internally connected to Earth Ground.

• Connect Shield to Earth Ground somewhere on the RS-485 bus (only at one point).

For all terminals on E50 meters:

• When tightening terminals, apply the correct torque: 0.37-0.44 ft·lb (0.5-0.6 N·m).

• Use 14-24 gauge (2.1-0.2 mm

BACnet Programming

BACnet Programming Overview

The E50H2-T2 is programmable via BACnet protocol and can easily be connected to a BACnet TP
network using an off-the shelf BACnet router. It uses five 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.
Configure 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
configuration register, AV1, which always returns zero when read) are all readable and stored in
nonvolatile memory so that they are retained if power to the device is interrupted.

Data values are 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,
AI26, AI27, AI37-AI45, AI47, AI50 and AI51) 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 objects 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 objects.

Analog Value (AV) Objects

Use the Present_Value property of the Analog_Value object for all writable variables in the meter
other than those used specifically for BACnet configuration, Time Synchronization (in the Device
Object).

Values are checked when written, 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 first. When
it reports a No_Fault_Detected status, the Present_Value of the object is current. These objects

BAS-SVX076C-EN

27

BBAACCnneett PPrrooggrraammmmiinngg

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

Figure 10. Analog Values (AV)

Figure 11. Analog Values (AV) [continued]

Analog Input (AI) Objects

Use the Present_Value property of the Analog_Input objects for all read-only numeric variables in
the meter other than those used specifically for device configuration (in the Device Object). .

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, AI26-AI27 and AI42-AI44) use floating-point

28

BAS-SVX076C-EN

BBAACCnneett PPrrooggrraammmmiinngg

data types (all AI objects use floating point data points). The resolution of the accumulated values
decreases as the value grows larger over time and more of the significant digits precede the
decimal point. If the size of the value limits the resolution unacceptably, read and store the
current value offline and reset the accumulators to restore finer resolution.

NNoottee:: As a best practice, verify 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 (BI) 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 goes 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 these
bits into a single decimal value. AI52 represents the status of all 14 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 significant bit and BI14 is the most significant bit.
