Section 5.5.9 List of General Fault Finding Procedures and Hints

5.5.9.6 Check of Backup Power Supply
The backup power supply and battery diagnostics are indicated in the system status display (see
Section 5.5.2.1, System Status and Plain Language System Messages) and by LEDs on the
Backup Power Supply SB510/511 front.
Fault finding in the controller cabinet is carried out as described in Figure 5-20.
The instructions are supported by the power supply block diagrams Figure 1-12 and Figure 1-13
in Chapter 1, Introduction.
5.5.9.7 Check of Processor Module
A description of the indicators on the module front is given to guide in the fault finding.
• Red LED F means module fault or a software error (not so likely). Replace the processor
module.
• Green LED RUN means module running normally.
The LED is turned off as a result of all kinds of system halts. If the green LED is turned off
read the system halt code on the character display and analyses the problem primarily as
described in Section 5.4, Error Messages. Take recommended measures. If not successful
you should methodically follow the fault finding instructions elsewhere in this chapter.
