CORRECTIVE ACTION
Use the statistics monitor command to verify the cause of the alarm. See step 2 if the unit
is overheated, and step 3 if the voltages are out of the allowed ranges.
Ensure that the MSAP2000 AAMS is installed in a well-ventilated area and that normal
operation of the fans is not inhibited. Keep the bottom, top and all sides clear of
obstructions and away from the exhaust of other equipment.
If the voltage levels are outside the allowed range, take a screen shot of the
statistics monitor command display and contact your vendor.
