9.1 Faults and Warnings Overview
Fault or warning conditions are indicated by the LED shown in Figure 7-3 on page 34, and also by LEDs associ-
ated with the inputs and outputs on the PLM. As the LEDs indicate several types of faults or warnings, a
brief textual description of the fault or warning is provided on the LCD display. Section 7.8.2 on page 34 details
the fault and warning indications that appear on the front panel. Table 9-1 lists the events that may have
triggered each fault or warning condition.
