problem in cases where less than 1 A draw is a normal condition.)
Out LED pulsing Amber
Indicates an over-current condition.
Out LED slowly pulsing Amber

In LED not active
Check to make sure that voltage to channel is less than 1 V.
“Momentary” means that the output(s) under control should only change
state (going from inactive to active or active to inactive) when the
appropriate handheld button or switch is positioned, and then only for the
duration of time that particular control remains positioned.
Investigate any
unexpected or unintended motion that occurs when
manipulating
the
handheld unit's
controls,
or when no handheld controls
are being
manipulated
.
Immediately stop operating if a jerky motion occur
s
while
manipulating the
handheld
’s controls
. Check the
handheld and
base unit diagnostic LEDs for
any indication of a problem. The particular SmaRT base unit manual
contains diagnostic descriptions.
Be aware that even if the handheld and base unit diagnostic LEDs do not
indicate a problem, one may be present, and further troubleshooting steps
may be needed.
If a problem is found, do not operate the SmaRT System until the problem
is resolved.
