Warning Descriptions and Resolutions
Warning conditions do not shut output power off, and the warning message is
cleared when the condition that caused the warning condition is gone. The
front panel only displays one warning message at a time. Overload warnings
indicate that an operating limit has been exceeded, and the unit has reduced
output power to remain within the allowable range.
When an overload warning
is active, the unit is not meeting set point. On the front panel, overload
messages end with an exclamation point.
Table 6-2 lists the warning messages that may occur on the HPG generator,
describes each warning message, and explains how to resolve the associated
problem.
