Message
Output was turned
off because the
MDXII unit was not
able to produce
output equal to the
programmed setpoint
level in the amount
of time specified in
the out-of-setpoint
timer. Thus the out-
of-setpoint timer
expired.
The MDXII unit has
exceeded maximum
operating
temperature (Table
3-4 on page 3-3) or
an inverter module is
not plugged in
completely.
The unit exceeded
the maximum
allowed output
power for 1 s, so the
output was turned off
for safety reasons.
Potential software or
hardware problem.

parameters for limiting
factors. That is, ensure
that your load impedance
matches the impedance
of the MDXII unit.
The fault message clears
itself when the unit cools.
If problem persists, call
AE Customer Support.
