SDM230-LoRaWAN User Manual
1 Introduction
This document provides operating, maintenance and installation instructions . The unit measures and displays the characteristics of single phase two wire(1p2w) supplies, including kWh, kVArh, kW, kVAr, kVA, PF, Frequency, Voltage, Current, dmd. THD etc. It support Max.100A direct connection, saving the cost to install external CTs. Maximum demand current can be measured over preset periods of up to 60 minutes. This unit has a built-in LoRaWAN module which allows long range wireless communication. Two pulse outputs are available for real time energy measurement.

1.1 Unit Characteristics
The Unit can measure and display: voltage and current Frequency Power, maximum power demand and power factor Active energy imported and exported Reactive energy imported and exported

The unit has password-protected set-up screens for: Changing password Demand Interval time, backlight time,scroll display time Reset for demand and partial energy measurements Pulse output type/ constant/ duration

1.2 Pulse outputs
The unit provides two pulse outputs. Both pulse outputs are passive type. Pulse output 1 is configurable. The pulse output can be set to generate pulses to represent total/ import/ export kWh or kVArh. The pulse constant can be set to generate 1 pulse per: 1 = 1 kWh/kVArh 10 = 10 kWh/kVArh 100 = 100 kWh/kVArh 1000=1000 kWh/kVArh Pulse width: 200/100(default)/60ms.

Pulse output 2 is non-configurable. It is fixed to export kWh. The constant is 1000imp/kWh.

1.3. LoRaWAN Classes
Eastron LoRaWAN energy meter is implement Class C functionality. The device will upload message after receiving the data sent from the network.

1.4 Active Upload Mode
The device also can be customized to active upload mode. Total 19 parameters can be set for automatic uploading. Interval time can be set from 0 to 255 through communication. 0 means the function is OFF. If

www.eastroneurope.com

SDM230-LoRaWAN User Manual
there are many parameters, the interval shouldn't be set too short in case of conflicting on data uploading. The meter will upload automatically once it joins the network. And after the interval time, it will upload again. The interval time is calculated since the last data uploading. Sometimes the interval time may have around 1-2 minutes difference due to the timer error.
1.5 Join
The unit uses standard LoRaWAN protocol for long range communication. Before Communication, the meter has to join the LoRaWAN network first. There are two Activation Ways for Joining: OTAA(Over-the-Air Activatioin) and ABP(Activation by Personalization).
To ensure the meter join gateway successfully, below information must be confirmed:
I. DevEui, AppEui, Appkey or DevAddr, NwkSKey, AppSKey information are correctly recorded into the gateway. II. The Uplink and downlink frequency are same as the gateway. III. RX2 (frequency and SF) information are same as the gateway.
If the Join delay function is ON, the meter will join the network with a few seconds delay by random.
1.6 Communication
LoRaWAN meter communicate based on international general purpose protocol. The communication data is placed in data segment of LoRaWAN protocol, they will be appointed follow the specified command format.
The format of standard LoRaWAN is shown below:

The following description of the text is defined the data in the segment of FRMPayload region in LoRaWAN protocol. The software in PC only need to get this part of data from gateway. According to the following protocol definition to parse the data.
The data format and encoding of meter communication protocol are modified based on the Modbus ASCII transmission mode. Remove the start and end characters from the Modbus ASCII transmission mode and change LRC validation to CRC validation.

SDM230-LoRaWAN User Manual
Encoding of data: communication data is encoded with ASCII, and each byte of data is sent with two ASCII characters. E.g.: a byte data 0x5b is encoded as two characters: 0x35 and 0x62 (ASCII code 0x35= "5", 0x62= "b")
Command format definition: I: The data format of the gateway sending the copy command:

Note: the reserved bit is fixed as 0x01

III: Note: the above commands need to be ASCII, so 1byte data will have 2 characters.

E.g. 1). Suppose to read the current data of the meter L1, the data sent by the gateway is the ASCII coded data as shown in the following table:

Note: the first address of the register of the meter L1 current is 00 06 and the number of registers is 2.
2) After receiving the above command, the meter will return the current L1 current data of the meter, as shown in the following table after ASCII coding.

SDM230-LoRaWAN User Manual

Note: Assume that the current meter's L1 current is 5.0A, since the data is in floating point format, the Hex data is converted to 0x40, 0xa0, 0x00 and 0x00.

To ensure the successful communication, below information must be confirmed: 1. The command is sent through Class C mode. 2. The command is sent in ASCII format.

2. Start Up Screens

6 Maintenance

In normal use, little maintenance is needed. As appropriate for service conditions, isolate electrical power, inspect the unit and remove any dust or other foreign material present. Periodically check all connections for freedom from corrosion and screw tightness, particularly if vibration is present.

The front of the case should be wiped with a dry cloth only. Use minimal pressure, especially over the viewing window area. If necessary, wipe the rear case with a dry cloth. If a cleaning agent is necessary, isopropyl alcohol is the only recommended agent and should be used sparingly. Water should not be used. If the rear case exterior or terminals should be contaminated accidentally with water, the unit must be thoroughly dried before further use. Should it be suspected that water might have entered the unit, factory inspection and refurbishment is recommended.
In the unlikely event of a repair being necessary, it is recommended that the unit be returned to the factory or nearest Eastron distributor.

7 Installation
7.1 Safety
The unit is designed in accordance with IEC 61010-1:2017 � Permanently connected use, Normal condition. Installation category III, pollution degree 2, basic insulation for rated voltage.
7.2 EMC Installation Requirements
Whilst this unit complies with all relevant EU EMC (electro-magnetic compatibility) regulations, any additional precautions necessary to provide proper operation of this and adjacent equipment will be installation dependent and so the following can only be general guidance:
Avoid routing wiring to this unit alongside cables and products that are, or could be, a source of interference.
The auxiliary supply to the unit should not be subject to excessive interference. In some cases, a supply line filter may be required.
To protect the product against incorrect operation or permanent damage, surge transients must be controlled. It is good EMC practice to suppress transients and surges at the source. The unit has been designed to automatically recover from typical transients; however, in extreme circumstances it may be necessary to temporarily disconnect the auxiliary supply for a period of greater than 10 seconds to restore correct operation.
Screened communication leads are recommended and may be required. These and other connecting leads may require the fitting of RF suppression components, such as ferrite absorbers, line filters etc., if RF fields cause problems.
It is good practice to install sensitive electronic instruments that are performing critical functions in EMC enclosures that protect against electrical interference causing a disturbance in function.

Warning

During normal operation, voltages hazardous to life may be present at some of the terminals of this unit. Installation and servicing should be performed only by qualified, properly trained personnel abiding by local regulations. Ensure all supplies are deenergized before attempting connection or other procedures.
Terminals should not be user accessible after installation and external installation

provisions must be sufficient to prevent hazards under fault conditions. This unit is not intended to function as part of a system providing the sole means of
fault protection - good engineering practice dictates that any critical function be protected by at least two independent and diverse means.

SDM230-LoRaWAN User Manual
The unit does not have internal fuses therefore external fuses must be used for protection and safety under fault conditions.
Never open-circuit the secondary winding of an energized current transformer. This product should only be operated with CT secondary connections Earthed. If this equipment is used in a manner not specified by the manufacturer, protection
provided by the equipment may be impaired. 7.3 Dimensions
