7.7. System Faults
7.7.1. Functional Overview
If a system malfunction occurs, the yellow FAULT
LED to glow. Additionally, an external alarm device
may activate and an audible alarm may sound if those
features have been enabled ( Section 6.8., Audible
Alarm ).
Depending on the nature of the fault, the RLDS may
or may not continue to operate normally. Under a
non-critical fault condition, the RLDS will continue
to measure and log data, but some peripheral
functions may be compromised. Under a critical fault
condition, action is required for the RLDS to operate
normally.
Various fault conditions are listed and explain what
action should be taken to correct the problem in
Section 7.7.2.1., Critical Faults . Note that the fault
codes are cumulative. For example, a code <4200> is
both a <4000> “REZERO VOLT TOL” and <0200>
“GAIN SET FAULT” combined, indicating two
simultaneous faults.
