Sel SEL-2241 User Manual

Schweitzer Engineering Laboratories, Inc. SEL-2241 Data Sheet
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 standalone RTAC modules, but is mounted in and receives power
from the Axion backplane.

The following figure shows the RTAC status LEDs that
aid system troubleshooting and the connectors for com-
munications and wiring.

Mechanical Installation
Each SEL-2242 chassis/backplane has ten slots, labeled
A through J. Only Slot A supports the SEL-2241 RTAC
module.
To install the RTAC, tip the top of the module away from
the chassis, align the notch on the bottom of the module
with Slot A of the chassis, and place the module on the
bottom lip of the chassis as Figure 2 illustrates. The
module is aligned properly when it rests entirely on the
lip of the chassis.
Figure 2 Proper Module Placement
Next, carefully rotate the module into the chassis, mak-
ing sure that the alignment pin fits into the corresponding
slot at the top of the chassis (refer to Figure 3). Finally,
press the module firmly into the chassis and tighten the
chassis retaining screw.
