RUNNING INTERNAL DIAGNOSTICS

The Internal Diagnostics test is a 5-second open load test. During the test, the HFV
generator takes a number of internal measurements to determine if the power
conversion and output sections are operating properly and to ensure that the
housekeeping (or logic) voltages are within tolerance. The internal diagnostics test
does not check the integrity of the rear panel control ports or related logic functions.
Use suitable precautions; this area contains high voltages that
could cause serious injury or death.

Explanation
This green indicator illuminates whenever output
power matches the requested power (within specified
accuracy spec). If RF power is on, an unlit indicator
indicates that an internal power limit has been reached.
This yellow indicator illuminates whenever:
• An overtemperature condition exists
• The input line voltage is out of range
• Loss of DeviceNet communications occurs
• An RF On sequence error occurs
Note: RF power will not turn on if the RF enable
signal is enabled before setting the
interlock. The sequence is to enable the
interlock first, then set RF enable.
When a fault conditions occurs, the LCD displays the
following:
Top line—displays: *****FAULT*****
Bottom line—[displays a type of fault]
If this indicator is on, see
page 6-3.
