Part 3: Further, optional steps
10.
Query the initialization status from the master, in order to analyze it:
SYST:MS:COND?
11.
Query the number of units initialized for the MS system (should be 5 with this
example): SYST:MS:UNIT?
12.
Query the nominal current of the MS system: SYST:NOM:CURR?
13.
Query the nominal power of the MS system: SYST:NOM:POW?
14.
Query the maximum resistance of the MS system: SYST:NOM:RES:MAX?
15.
Query the minimum resistance of the MS system: SYST:NOM:RES:MIN?
16.
Configure protection values, for example OCP: CURR:PROT˽400
17.
Configure events, for example:
- set OCD to 2100 A: SYST:CONF:OCD˽2100
- then define the alarm type for OCD to "warning": SYST:CONF:OCD:ACT˽WARNING
The adjustment limits ("Limits") require extra treatment, because they are tied to the set
values. Means, with the set values being reset to defaults during the MS init, for example
the set value of current would be at maximum and thus the related adjustment limit IMax
cannot be set lower than this without prior changing the set value.
18.
Narrow the adjustable range of values, for example limit the max. current set value
to 2200 A
- First, set the current value down to anything lower than the desired limit, like the
minimum: CURR˽MIN
- Second, set the adjustment limit to the value translated for the master unit:
CURR:LIM:HIGH˽2200
With these settings applied, the current should be at 0, because the lower adjust limit has
not yet been changed. The current will me monitored for the threshold of 2100 A by the
event system and since it is adjustable up to 2200A, the true current might exceed the
threshold and cause an OCD event, which would only generate a warning on screen, but not
switch off the DC Input.
19.
To start working with your MS system, switch the DC Input on: OUTP˽ON
The system will remain configured and keep the settings when power-cycling it. The master
unit has to initialize the MS and the slaves at least one time after power-up. The status of
the first automatic initialization can be read from the master by custom software and
depending on the result, the software could trigger further steps like the ones above,
probably from at least step 8 or if required even from step 1.
