Sequential
operations
Most of the lengthy operations of the XMP 2600 are carried out by the Power
Modules (output changes, ramping etc.). This means that those lengthy operations
can be (and usually are) overlapped in their execution. More often than not this is an
advantage, but sometimes you may wish to serialize (sequentially perform) such
operations (e.g. change the output of module No.2 after module No. 1 has finished
ramping).
You can use the hardware signals TRIG and SYNC to serialize operations.
As mentioned before, a Power Module can generate a SYNC signal when its output
change is done. Feeding the SYNC signal into the TRIG input enables other Power
Modules to react to the aforementioned Power Module’s end of operation, thus
achieving operations serialization.
To use this mechanism, proceed as follows:
1. Program all the Power Modules, but the one you wish to use, to never
generate a SYNC.
2. Program the Power Module that will perform the first operation to generate
a SYNC on output settle.
3. Program the Power Modules that are going to perform the second operation
to react to a trigger. Use the ARM mechanism if necessary.
4. Program all the other Power Modules to ignore the trigger.
5. Initiate the first operation.
When the first operation is complete, the Power Module that performs it will
generate a SYNC. This SYNC signal will, in turn, generate a trigger to the other
Power Modules causing them to initiate the second operation.
Store and Recall
The XMP 2600 has ten storage areas each capable of holding the values of all the
parameters of all the power modules. Using these storage areas you can save a
complete “state” of the power supply system and restore it later.
The stored data is kept in a battery backed up RAM and is not cleared by resetting
the power supply or cycling its power.
Storing a
state
To store a power supply state proceed as follows:
Make sure the display is in status mode.
Move the cursor to a condensed status symbol of any power module
(use the LEFT / RIGHT selection keys).
Press the STO key. An input field opens at the display’s lower row, in
the system message area (“STORE into #”), ready for you to specify a
storage number.
Press a digit key (0 to 9) to specify a storage number. A confirmation
question (“OK?”) is displayed. If the storage area already has data
stored in it, a message (“NOT FREE”) is displayed on the upper row of
the display.
To finish the operation, do one of the following:
o Confirm the store operation by pressing the ENTER key.
o Cancel the store operation by pressing the DEL key.
