4.5.2 RESETTING SHUTDOWN FAULTS
The shutdown fault is reset as follows:
1.
Set the OUTPUT POWER Switch to the OFF position.
2.
Wait for the SHUTDOWN LED to extinguish. This LED will remain lighted until the
condition which caused the shutdown to occur has been corrected. In the case of
shutdown due to over-temperature this may take some time. The output contactor cannot
be engaged until the shutdown fault has been cleared.
NOTE: The SHUTDOWN LED is latched on when a fault occurs. The OUTPUT POWER Switch
or the Output Enable of the UPC MUST be placed in the OFF position before the SHUTDOWN
LED will extinguish, even if the original fault no longer exists.
3.
After the SHUTDOWN LED has been extinguished, the unit will function normally.

OUTPUT VOLTAGE FORMS
This paragraph describes the various output voltage forms for which the ASX-Series Power Source
can be configured.
A recommended strategy for selecting the optimum output voltage form is based two basic
philosophies. The first is to use a direct-coupled output form whenever possible. The second is to
select the minimum voltage range necessary to drive the load.
Direct-coupled output is preferred because the output impedance is extremely low. A second
reason to use the direct-coupled output form is that low frequency limitations associated with
transformer outputs do not exist. This is especially true when attempting to perform sub-cycle
transients.
Selecting the minimum voltage range necessary to drive the load allows the power source to
operate more efficiently. This results in less heat being dissipated into the surrounding
environment.
Paragraph 4.6.1 discusses the various structures associated with the different output forms.
