APPENDIX 11

11.1 Faults and Warnings
Overview
The various fault or warning conditions that may
arise in the PLM are indicated by the tricolor LEDs
in the eight soft function buttons around the display.
Because each LED indicates several types of faults
or warnings, a brief textual description of the fault
or warning type is given on the display adjacent to
the soft button(s).
Sections 9.10.2 and 9.11 detail all the warning and
fault indications.
Table 11.1 provides additional explanation of what
problems the PLM might have encountered to give
rise to the each of the fault or warning conditions.
Note that some of the conditions give rise to both
a warning and a fault indication; in these cases
the warning is given by a yellow LED indication as
the operating parameter in question approaches
the safety threshold, with the fault state being
indicated by the LED turning red when the threshold
is actually reached (with a mute being applied in
some cases).
