Testing the modules Turn-On Checkout
Retain
If the Power On Retain (POR) flag is set, all the Power Modules will be
programmed to the state they were in just before power was turned off. The state of
the Global Output Enable condition will, also, be restored.
Initialize
If the Power On Retain flag is cleared, all the Power Modules will be programmed
to the following conditions:
♦ Output Voltage set to 0.
♦ Output Current limit set to minimum.
♦ Output disabled.
♦ Protection mode set to Auto (tracking).
♦ All other features are disabled.
The Global Output Enable condition will be set false (global disable).
Scan
Exceptions
During scan, the Channel state will show a question mark (“?”) if there is any miss-
match between the previous state of the installed Power Module and the current
state.
Once the scan is done, channels will get their permanent state, except for a situation
where the scanned channel was found to have a different (than was know) kind of
Power Module installed. In this case, the question mark state will remain for the user
to resolve. This type of scan error can not be resolved automatically because it may
indicate that a Power Module was replaced with a different kind of module, but it
might, also, indicate a defective Power Module.
To resolve this situation, select the Power Module in Set-Up Mode. The Power
Supply will present some guiding questions to be answered by selecting “YES” or
“NO”. Use the Flip (up and down arrow) keys to select the proper answer and press
ENTER to confirm. If the Power Module in question is not new or its data is not
what was expected then the Power Module will be rendered NON-OPERATIONAL.
In such a case, refer the unit to a qualified maintenance laboratory.
Testing the modules
Power Modules can be tested in two levels: Control Circuit Confidence Test and
Power Module Test.
Confidence
Test
In Channels Status Mode (default operating mode following power-on), select the
Power Module to be checked - use the selection (left and right arrow) keys to move
the cursor to the channel where the Power Module is installed.
Using the Flip (up and down arrow) keys, select to display the MAX values.
MAXimum Voltage and Current available from the Power Module are displayed. In
this mode the system, continuously, performs a confidence test of the selected Power
Module with the results being displayed as: “BIT=00,00”. The equal sign (“=“)
blinks to indicate the repeated performing of the confidence test. For details on the
result of the BIT see the Status Reporting section of the Programming Manual.
The Confidence Test performs the following checks:
♦ Processor Memory.
♦ Control circuits` power supplies.
