Appendix; Faults And Warnings Overview - Lab.gruppen PLM Series Operation Manual

11 APPENDIX

11.1 Faults and warnings
overview
Indication of the various fault or warning conditions
that may arise in the PLM is given by the tricolor
LEDs in the eight soft buttons around the display.
Because each LED indicates several types of fault
or warning, a brief textual description of the fault or
warning type is given on the display adjacent to the
soft button(s).
Section 9.10.2 details 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).
