1. Ensure that the AC/DC input service is disconnected.
2. Install the interface cable between the host controller and the ReFlex
Power™ Controller module.
3. Connect an appropriate input source to the Active Load module.
4. Configure the host controller for communications with the ReFlex
Power™ Controller module.
5. Turn on the Mainframe AC/DC input service.
6. The modules will first execute a power-on self-test. Also the internal fans
are run at maximum speed for several seconds, and then back to slow
speed.
7. In the following paragraphs, commands include a channel number, [n].
The channel number corresponds to the slot of the ReFlex Power™
Mainframe where the module is located, counting left to right, 1 through
12. For example:
SOUR[n]:CURR 5 will be
SOUR4:CURR 5 for slot-1
SOUR7:CURR 5 for slot-2
8. Additionally, model specific parameter values must be added for full-scale
voltage and current. They are shown in the following examples as floating
point numerical values, . For the Active Load modules, the values
are as follows:
Full-Scale Current:
HPAL: 30
LPAL: 15
Therefore, for an 750W Active Load module in slot 4, the command for
full-scale current would be SOUR4:CURR 30; for a 375W Active Load
module, it would be SOUR4:CURR 15.
9. Verify communications with the ReFlex Power™ Controller module by
issuing an SCPI *IDN[n]?, where “n” is a channel number that
corresponds to the slot of the ReFlex Power™ Mainframe where the
module is located, counting left to right, 1 through 12.
