Installing the Input Module

The front panel of the input module contains a green RUN and a red FLT
(fault) indicator (Figure 2.5). At powerup, an initial module self-check
occurs. If there is no fault, the red indicator turns off. The green indicator
will blink until the processor completes a successful write block transfer to
the module. Upon completion of a block transfer write (BTW), the green
RUN indicator will be on and the red FLT indicator will be off. If a fault is
found initially or occurs later, the red FLT indicator lights. Possible module
fault causes and corrective actions are discussed in Chapter 7,
Troubleshooting.
