Indicator	Description
OVERTEMP	A flashing yellow LED warns that the internal cold plate
	temperature is approaching the shutdown limit.
	A continuously lit LED indicates that the internal cold
	plate temperature has exceeded the allowable limit. When
	this condition occurs, the RF turns off and can be turned
	back on only after the temperature drops below the
	warning temperature limit and a RF Off command is given
	to clear the fault. See “Troubleshooting guide” on page 6-1
	for more information.
ALARM	This yellow LED indicates that the generator has turned off
	RF output due to some limit or alarm condition in the
	generator. Some of the conditions that can cause an alarm
	are:
	• Over-temperature
	• Exceeded internal protection limits
	• AC PWR outside the limits
	In the event of an alarm condition, after correcting the fault
	condition, an RF OFF signal has to be given to reset the
	generator since the generator has turned off RF output. See
	“Troubleshooting guide” on page 6-1 for more
	information.

APEX PANEL ILLUSTRATIONS

The appearance of the front and real panels of the Apex generator is highly variable due to the number of customer-selectable options available in the product line. These options mean that the presence or absence or certain connectors, the types of connectors, and the locations of certain options (on the front or the rear panel) are variable. The following illustrations show a basic Apex option, with labels for the options that you may or may not have on your Apex unit. To find information about any of these options, see “Using this Manual to Find Information for Your Generator” on page 1-1.
