L1 Controller Error Messages

Table 13-2 lists error messages that the L1 controller generates and displays on the L1
display. This display is located on the front of the CR-bricks, R-bricks, IX-brick, and
PX-bricks.
Note: In Table 13-2, a voltage warning occurs when a supplied level of voltage is below
or above the nominal (normal) voltage by 10 percent. A voltage fault occurs when a
supplied level is below or above the nominal voltage by 20 percent.
