POWER FOR THE RTU Eagle Research provides an XA-Series UPS (uninterruptible power supply) and SPS (solar power supply) for unit power to the RTU. The RTU typically operates on an AC voltage power system with a 2.2 amp hour backup battery. Solar power systems with battery backup can be designed for any application where AC is not readily available. The sizing of solar systems depends on the geographic location, degree of sun exposure, equipment power consumption, and site obstructions.
7. You can also change parameter values, and view or acknowledge active alarms using the display and keypad. See information on these functions starting on pages 21. COMMUNICATIONS To communicate with the XARTU/5, the Site ID in the device must be the same as the Site ID entered in the software package. The Site ID is a unique identification number (1 to 65,535), which allows the software packages to communicate with the RTU. The default Site ID number is 1.

WIRING THE PULSE INPUTS The XARTU/5 comes standard with eight pulse inputs that are software programmable for Form A or C, and high speed or low speed. These inputs can be used as simple pulse counters, or in more demanding applications such as card readers. The table below shows the terminal wiring for the pulse inputs.
WIRING THE ANALOG INPUTS The XARTU/5 comes standard with eight single-ended analog inputs with floating common. These are 16-bit resolution inputs with a maximum of ±3 LSB integral linearity error. Additional box temperature and supply voltage level inputs are also standard. All analog inputs are software calibrated and have a ±4% over-range. The input impedance is greater than 100 megohms. Jumper JP5 on the IOT60 expansion/termination board determines the power input to the transmitters.
WIRING THE DIGITAL I/O’S The XARTU/5 comes standard with sixteen memory-mapped digital I/O lines. They are programmable, in groups of eight, as inputs or outputs. Digital outputs can be configured as simple discrete outputs, or as precisely timed pulse outputs.
OPTIONAL EQUIPMENT The standard XARTU/5 is configured to handle the majority of instrument and measurement applications. However, when additional measurement and control features are required, the following optional internal / external expansion boards and items may be added.
OPTIONAL 24VDC ANALOG SUPPLY The optional 24 VDC isolated transmitter loop power supply provides power for all 16 analog input channels. The table below shows the terminal wiring for the 24 VDC isolated output. Isolated 24 Volts (External use) 24VISO GND XARTU/5 Terminal Location 55 56 The table below lists the specifications for the optional 24 VDC supply used in the RTU.
OPTIONAL ANALOG INPUT CONDITIONING CARD (EBM80/AI8) With the 8-channel EBM80/AI8 analog input card, the XARTU/5 can support an additional eight analog inputs for a total of 16. All the analog inputs have gas tubes and transorb protection. The analog inputs can be configured for either 4-20 ma or 1-5 volts. Remove resistors R1 – R8 for 1-5 volt inputs (one for each channel). Fig. 5 – Analog Input Card Analog Input Card (EBM80/AI8) XARTU/5™ Manual Copyright© 2013 Eagle Research Corporation® REV 11.1.
OPTIONAL ANALOG OUTPUT CARD (XA-AO) The Analog Output Module and connecting cable provides two two-wire, loop-powered, optically isolated, precision 4-20mA outputs. This module interfaces with the XARTU/5 to provide 4-20mA outputs for flow rate, pressure, or numerous other controls and monitoring applications. Up to four modules can be connected to the RTU.

OPTIONAL DIGITAL INPUT CARD (EBM80/DI4) NOTE Four of the digital I/O lines must be sacrificed to use the digital input card. Fig. 7 – Digital I/O Card Digital I/O card (EBM80/DI4) XARTU/5™ Manual Copyright© 2013 Eagle Research Corporation® REV 11.1.
OPTIONAL RELAY CARD (EBM80/RC4) The optional mechanical relay card has four channels for generating pulse outputs. The outputs are fused at 5 amps, and an individual LED provides the status of each output. Jumper JP1 determines whether the +12 VDC power source for the relay coil is internal or external. The default setting sources the relay coil externally. Jumpers JP2, JP3, JP4, and JP5, one for each relay, determine whether the relay coils are energized on a low or high logic state from the RTU.
OPTIONAL SOLID-STATE RELAY CARD (SSRC4) The optional solid-state relay card is a four-channel, optically coupled card used to control direct current output voltage to field equipment. It is an ideal choice in applications formerly governed by older style mechanical relay circuits. Wear, arcing, noise, and other problems inherent with mechanical relays are eliminated. The main purpose of the SSRC4 is to drive reversible DC motors.
OPTIONAL INDUCTIVE PROXIMITY SENSOR (EBM80/IPS) NOTE Four of the digital I/O lines must be sacrificed to use the inductive proximity sensor card. Fig. 9 - EBM80/IPS Inductive Proximity Sensor XARTU/5™ Manual Copyright© 2013 Eagle Research Corporation® REV 11.1.
OPTIONAL MODEMS (2400 AND 33,600 BPS) The optional modems offer automatic answering and dialing. They can communicate at speeds up to 33,600 baud. The EEPROM editor in the XARTU/5 can be used to configure the baud rate for your modem. There are five status LEDs: RI (ring indicator), DTR (data terminal ready), DCD (data carrier detect), RXD (receive data) and TXD (transmit data). Jumper JP6 on the IOT60 expansion/termination board controls how the modem is powered.
Group 3 OPTIONAL USER KEYPAD AND DISPLAY Another useful option to the XARTU/5 is a factory mounted keypad and display. The keypad and display may be used to access, change, and view programming data and stored information while on site. The display feature may be internally and/or externally mounted. When external, the display alone may be viewed from outside the unit without opening the door. When internal, the display is combined with an interactive keypad (see Fig. 10).
GROUNDING Because of the potential for equipment damage and injury to personnel, certain practices should, and often must, be observed when installing RTU systems. Of these practices, proper grounding is possibly the single most important.
OPERATING MODES The XARTU/5 operates in any of the following four standard modes: Display Alarm Configuration Calibration To access any operating mode, press the keypad key that corresponds to the mode you want: conf alrm cal esc for configuration mode for alarm mode for calibration mode to return to a previous mode from any other mode DISPLAY MODE In display mode only limited parameters with assigned labels and function keys can be viewed.
The RTU can be configured to monitor and alarm on any condition including, but not limited to, the following: First Time Power AC Power Failure Low Supply Volts High and Low Flow Rate High and Low Pressure High and Low Differential Pressure High and Low Temperature Current Day Flow (Transportation Limit) Low Voltage Shutdown Box intrusion Liquid levels Valve status NOTE Additional hardware equipment and configuration may be required for some alarm monitoring.
Viewing Parameters In configuration mode, any parameter value may be viewed. One method is to use the Jump key to directly view database items. Press Jump and then enter the address of the parameter followed by pressing the ent key. The top line on the display is the software address, and the bottom line is the value. Function key assignments are still valid, so often-viewed parameters may be accessed in this manner.
editable audit trail. In the standard RTU configuration, the audit trail is disabled. You can enable audit trail logging by editing address 010313 to 300 at the keypad, or by using Talon software. The maximum memory allowed for audit trail is (300 records * 24 = 7,200). NOTE Once the audit trail is enabled (a value greater than “0”), the user cannot disable the audit trail without a full unit initialization. Reloading the database will not disable the audit trail.
System analysis using flow rate and pressure Support for estimating gas volume consumption in cases of meter or instrument malfunction Configuring Four Parameters for display This feature allows the user to configure four parameters that can be shown at the same time on the display. It is helpful when troubleshooting the unit. The parameters must be configured before they can be displayed. To configure and display the four parameters: 1. Move to the first parameter to be configured. 2.
and cal and edit System information (ROM version, unit S/N, calculated Checksum) Toggles keypad beeper on and off CALIBRATION MODE Calibration mode allows the user to calibrate the analog inputs such as differential pressure, pressure, and temperature. While operating in the calibration mode, the RTU continues to periodically update volume. The analog input value used for calculations is the value measured when calibration mode was initially entered.
reference matches the unit's default, simply press the ent key to collect the new point. Otherwise, key in the value of the current reference before pressing the ent key. The unit should display Calculating. . . briefly, and then display the new point. Pressing the esc key instead of the ent key at this point aborts the operation and returns you to the calibration prompt. 6. Apply the appropriate span (full-scale) reference to the transmitter and wait for the reading to stabilize. 7.
3. The unit will enter calibration mode and the display will show the current value and mA representation of the analog output signal. For example, Eng: 48.000 mA: 11.680 where 48.000 is the analog output reading representing 11.680 mA. The top line will alternate between four different readouts Eng: 48.000, UP/DN TO CHANGE, CALIBRATING, and the parameter label while the bottom line will always show the mA value. 4. Connect a multimeter in series with the loop to measure the current.
9. Press or to increase or decrease the output until the meter reads 20mA, or the current span reference matches the field equipment. Press ent to collect the new point. 10. Steps 5 - 9 are required only once. They may be repeated as often as necessary while in calibration, but only the most recent point will be saved on completion of calibration. 11. To permanently store the results of the calibration press ent, and the unit will prompt Enter to accept Calibration.
CALIBRATION Calibration is a crucial element of any program of scheduled maintenance. However, because of the RTU's design, software calibration does away with the need for laborious field adjustments. XARTU/5™ Manual Copyright© 2013 Eagle Research Corporation® REV 11.1.
