The EM-RS485 is a three channel meter, capable of monitoring single-phase, two-phase and three-phase systems, as well as 3 independent single-phase systems with one meter. The EM-RS485 meter offers BACnet MS/TP and Modbus RTU protocols and 2 pulse inputs to maintain flexibility during installation and operation. The EM-RS485 is compatible with all sizes of current/voltage transducers (CVTs). With the EM- RS485 intelligent meter technology, the device self-configures baud rate, serial format, protocol, and address (BACnet only) - eliminating additional configuration steps. Each CVT is independently calibrated to measure and digitally communicate power values to the meter. The CVT’s flexible Rogowski coil makes installations less burdensome. The voltage connections are made directly into each CVT - keeping all high voltage away from the meter. Each CVT is rated from 90 to 600VAC. WARNING !

Call 1-866-660-8864 o Network Connectivity The EM-RS485 installs with minimal user configuration. The EM-RS485 is designed for use on both BACnet and Modbus networks. The meter is designed to automatically identify the network baud rate, protocol type, serial formats and self-address (BACnet only) for quick startup. The following details the steps required to add an EM-RS485 meter to an existing network. Separate steps are detailed based on the network protocol type (BACnet & Modbus). Modbus Network Connectivity Once the meter has been connected to the RS-485 network, it will automatically detect Modbus traffic and begin auto- configuration. The EM-RS485 will detect and match baud rate, parity and stop bits. Connect the EM-RS485 to a Modbus network through the following steps: 1. Wire the EM-RS485 meter to an existing Modbus network utilizing the wiring diagrams in Section 3 - Wiring. 2. Apply power to the EM-RS485 meter. 3. The device will analyze the network traffic for the following parameters: baud rate, serial format and protocol. During this configuration, the RS485 LED y should display approximately 15-30 seconds of blinking activity in yellow while the meter configures itself to the network.

The RS485 LED y will appear green after the meter has discovered and set the protocol type, baud rate and serial format. If the RS485 LED does not appear green, see the Network Activity subsection. 5. The EM-RS485 ships with a default Modbus address. The default address will be between 100-199. To identify the default address, look at the serial number on the EM-RS485 label. The last two digits will form the default serial Modbus address. See below label example for where to find your meter serial number: 240042 L3C T Example: This meter shown would have a default Modbus address of 142, based on the serial number. Alternative address assignment can be accomplished through manual configuration (See Section 7 - Auto-Detection Settings - Setting 1. Address Assignment) or by writing to the address register utilzing the EM Modbus Protocol Guide document. Tip: Customizing the Modbus address from the Senva default? Mark the newly assigned address on the EM-RS485 label with a permanent marker for a quick reference point in the future: Class 2 60 °C Max address Device Status BACnet Network Connectivity Once the meter has been connected to the RS-485 network, it will automatically detect BACnet traffic and and begin auto- configuration. The EM-RS485 will detect and match baud rate, parity, stop bits and identify an unused master MAC address to occupy through the following steps: 1. Wire the EM-RS485 meter to an existing BACnet network utilizing the wiring diagrams in Section 3 - Wiring. 2. Apply power to the EM-RS485 meter. 3. The device will analyze the active network for the following parameters: baud rate, serial format, protocol and first available MAC address.

Call 1-866-660-8864 p Configuration Settings The EM-RS485 also allows for manual configuration of the following Setting Groups: 1. Address Assignment 2. Protocol Type Configuration 3. Baud Rate Configuration 4. Serial Format Configuration 5. PowerPrint ‘Power Quality Alarm’ Options This section will further define the Auto-Detection Settings and detail alternative settings that can be manually selected in Section 8 - View and Edit Settings. Setting 1. Address Assignment The EM-RS485 is designed to self-address without user configuration. BACnet: If the EM-RS485 is connected to a BACnet network, the meter will analyze the network traffic to detect an unused MAC address. The device will self-assign that MAC address to the meter. (See Section 6 - Network Connectivity) Modbus: If the EM-RS485 is connected to a Modbus network, the meter default address will be between 100-199, based on the last two digits of the serial number. (See Section 6 - Network Connectivity) For manual configuration, the EM-RS485 address can be set through the network utilizing the EM BACnet Protocol Guide or EM Modbus Protocol Guide documents or on the meter via Section 8 - View/Edit Settings. Manual configuration address options: 1, 10, 77, 101, 149, 192. If the meter displays ‘Other’ in the View/Edit Settings Mode, the address has been manually assigned via the network. Setting 2. Protocol Type Configuration The EM-RS485 is designed to automatically detect and configure to a BACnet or Modbus protocol. If the meter is transferred to a new network while in the default Auto-detect setting, it will reconfigure the protocol type to match the new network. Manual configuration of the protocol type is available via Section 8 - View/Edit Settings. Manual configuration protocol options: BACnet; Modbus RTU; BACnet, Modbus RTU; Modbus ASCII; BACnet, Modbus ASCII; Modbus ASCII, Modbus RTU; BACnet, Modbus RTU, Modbus ASCII. Setting 3. Baud Rate Configuration The EM-RS485 is designed to automatically detect and configure baud rate. In addition to the default setting for auto-detection of the baud rate, manual configuration of the baud rate is available via Section 8 - View/Edit Settings. Manual configuration baud rate options: 9600, 19200, 38400, 57600, 76800, 115200. If the meter displays ‘Other’ in the View/Edit Settings, the meter has detected or been manually assigned a baud rate that is not listed above. Setting 4. Serial Format Configuration The EM-RS485 includes auto-detection of data bits and parity of the network. The device will auto format to the correct setting. Manual configuration of the serial format is also available via Section 8 - View/Edit Settings. Manual configuration serial format options: No parity, 8 data bits (BACnet default); No parity, 7 data bits; Even parity, 8 data bits (Modbus RTU default); Even parity, 7 data bits (Modbus ASCII default); Odd parity, 8 data bits; Odd parity, 7 data bits. If the meter displays ‘Other’ in the View/Edit Settings, the meter serial format has been manually assigned via the network. Setting 5. PowerPrint ‘Power Quality Alarm’ Options PowerPrint is a power quality alarm that enables the meter to learn and save characteristics of the system being monitored. Based on recorded values, the meter can provide alarm conditions and allow user to evaluate system status at a later time. The PowerPrint setting is off by default. When PowerPrint is turned on, the meter identifies each CVT connection and saves settings on the following parameters: 1. Which channels have a CVT connected 2. Unique identity of each CVT 3. Phase voltage 4. System frequency 5. Phase voltage angle PowerPrint can only learn and save characteristics for channels with a properly installed CVT. If the CVT is displaying a warning or error condition during Normal Operation, take the corrective action to resolve the installation error prior to enabling PowerPrint. PowerPrint can be enabled through Section 8 - View/Edit Settings or through the network utilizing the EM BACnet Protocol Guide or EM Modbus Protocol Guide documents. Once PowerPrint has been turned on and the system characteristics have been saved, the conditions below will be displayed on the meter LEDs as a warning or error during Normal Operation (See Section 4 - Normal Operation Mode): Alarm ConditionParameter Missing sensorCVT missing on one or more channels Unexpected sensorCVT identity does not match original CVT saved in Powerprint Brown out voltageVoltage < 10% from saved voltage 2 Surge voltageVoltage > 10% from saved voltage 2 Frequency drift 1 Frequency not within +/-0.2Hz from saved frequency 2 Phase driftPhase voltage angle variance > +/-30 o from saved angle 2 1 PowerPrint will not monitor frequency variance if system frequency is not 50 or 60Hz when PowerPrint is saved. 2 Parameters are configurable via the network.
