SEL-2241 Real-Time Automation Controller (RTAC) Each SEL Axion® system requires an RTAC module to serve as the system CPU. The SEL-2241 RTAC has all of the communications and custom logic capabilities of the stand-alone RTAC modules, but is mounted in and receives power from the Axion backplane. Mechanical Installation The following figure shows the RTAC status LEDs that aid system troubleshooting and the connectors for communications and wiring. Each SEL-2242 chassis/backplane has ten slots, labeled A through J. Only Slot A supports the SEL-2241 RTAC module. RTAC ENABLED ALARM 1 Notch for Module Alignment SEL-2241 RTAC Front Panel, Copper Ethernet Schweitzer Engineering Laboratories, Inc. To install the RTAC, tip the top of the module away from the chassis, align the notch on the bottom of the module (shown in Figure 2) with Slot A of the chassis, and place the module on the bottom lip of the chassis as Figure 3 illustrates. The module is aligned properly when it rests entirely on the lip of the chassis.

Connections Communications Ports NOTE: Never connect two RTACs via USB to one PC. Proper Module Placement Next, carefully rotate the module into the chassis, making sure that the alignment pin fits into the corresponding slot at the top of the chassis (refer to Figure 4). Finally, press the module firmly into the chassis and tighten the chassis retaining screw. All web access, settings changes and ODBC connections use either the RTAC Ethernet ports or the front USB type B port. Until you have configured the Ethernet interfaces on the RTAC, you will need to use the supplied USB type B cable to...

Step 7. Make all necessary connections to the module according to the applicable connection instructions in this section. Step 8. Apply power to the Axion node. Step 9. Use IP address 172.29.131.1 to access the RTAC web interface through the supplied USB cable. See Section 6: Security in the ACSELERATOR RTAC SEL-5033 Instruction Manual for RTAC web password setup. Also enable all necessary communications ports. Jumpers The SEL-2241 RTAC jumpers come preset and should not be moved except as Section 3: Testing and Troubleshooting in the SEL-2240 Instruction Manual describes. Table 3 shows the configurable...
