Page 5: Introduction
The requisite current input(s) are obtained via current transformers (CT). The Ri3 can be configured to work with a wide range of CTs, giving the unit a wide range of operation. Built-in interfaces provide pulse and RS485 Modbus™/JC N2 outputs. Configuration is password-protected. -
Page 6: Pulse Output
Measurements Pulse Output This provides a relay pulse output that clocks up measured active (Wh) or reactive (VArh) energy. The unit can produce one pulse for preset quantity of energy imported or exported. The pulse divisor and pulse width can be set from the Set-up menu as detailed in Section 0. 2 Start Up Screens The first screen lights all display segments and can be used as a display check. -

Page 11: Dit Demand Integration Time
Setting Up dIT Demand Integration Time This sets the period in minutes over which the Current and Power readings are integrated for maximum demand measurement. The options are Off, 5, 8, 10, 15, 20, 30, and 60 minutes. From the Set-up menu, use the (up) and (down) keys to select the dIT option. -
Page 12: Rset - Reset
Setting Up RSET - Reset Use this option to restart Energy Hours (kWh, kVArh) and/or Current/Power Demand measurements from zero. These can be set individually or all together. From the main Set-up menu, use the (up) and (down) keys to display the Reset screen. - Page 13 Setting Up Press to exit the format selection routine. SET will be removed. If you have selected N2 format, you can use the key to select the RS485 address option and set it as detailed on page 14. If you have selected ModB format, set the serial parameters as follows: Use the key to cycle through the Baud, parity, stop bits and address menu options.
- Page 14 Setting Up Press to confirm your selection. SET will be displayed. Press to exit parity setting routine. SET will go off and keys can be used to select a different Comms parameter. Stop Bits(not applicable for JC N2) Note that, if Parity is set to Odd or Even, Stop Bits will be set to 1 and cannot be changed. Use the keys to select the Stop Bits option.

Setting Up (not applicable for JC N2) Modbus™ Word Order This screen shows the word order (Hi/Lo) of the 8-bit bytes in the Modbus™ message format. Normal is Hi first. This setting can only be changed from the Modbus port. See the Cix Communications Guide for further information Pulse Output This option allows you to configure the pulse output. - Page 16 Setting Up Rate Use this to set the energy represented by each pulse. Rate can be set to generate 1 pulse per 0.001 = 1 Wh/VArh 0.01 = 10 Wh/VArh = 100 Wh/VArh = 1 kWh/kVArh = 10 kWh/kVArh = 100 kWh/kVArh = 1 MWh/MVArh = 10 MWh/MVArh The rate cannot be set to a value that could result in more than 2 pulses per second.

Page 17: Energy Units And 1% Limit
Setting Up Press to confirm your selection. The SET indicator will appear and the display will stop flashing. Press to exit Pulse Width setting routine. SET will disappear and the keys can be used to select a different Relay parameter. 4.10 Energy Units and 1% Limit Use this option to set the displayed energy units multiplier and to set a 1% limit on measured energy on or off. -
Page 18: Test
Setting Up Press to exit Units setting routine. SET will be removed. 1% Limit With the 1% Limit On, line noise below 1% of maximum power will be displayed as zero and will not accrue to the energy reading. With Limit Off, the 1% symbol will be appear on the power and energy screens to show that low power readings will be displayed and utilised. - Page 19 Setting Up Lights all LED segments so that display segments can be checked. Press to exit. Toggles display segments alternately. Press to exit. Shows the voltage and current phase sequences. Press to exit. Press to exit the selected test display mode. Press again to return to the main Set-up menu.

Page 26: Installation
Installation 7 Installation The unit is intended for mounting on a standard DIN rail. Hook the unit onto the top of the rail and press the bottom of the unit until it locks in place. To remove the unit from the rail, lever down the black tab at the bottom of the unit to release it from the rail. -
Page 27: Case Dimensions
Installation 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;... -
Page 28: Additional Considerations For Three Wire Systems
(ground) to avoid the possibility of electric shock from the neutral terminal. Auxiliary Supply The Integra Ri3 should ideally be powered from a dedicated supply; however it may be powered from the signal source providing the source will always be within tolerance for the auxiliary supply voltage range. -
Page 29: Rs485 And Modbus™ Or Jc N2 Protocol
Installation Voltage lines and auxiliary supply must be fused - see above. RS485 and Modbus™ or JC N2 Protocol The RS485 interface in conjunction with the Modbus™ or JC N2 protocol allows the unit to be interrogated and provide a response detailing the readings it has taken. This can be used for remote monitoring by a PC or SCADA system. -
