Sorensen SLM-Series DC Load Operation
M540071-01 Rev C 3-9
Press the LIMIT key until rAnGE appears on the upper 5-digit display. Use the inc/dec
arrows to set AUTO or rAn2. rAn2 forces the load to Range 2 for CC and CR mode, as
defined in Table 3-2.
Over Current Test (OCP Test)
An OCP test automatically steps the current from a start current (iStAr) to a stop current (iStOP) in
equal increments (iStEP). When the voltage falls below a threshold voltage (Uth), the test stops and
the current setting is saved.
The LIMIT key steps through each of the first three setup parameters. The threshold voltage setting
appears after the OPP test parameters.
After setting the four parameters (start, stop, step and threshold), refer to Test Mode instructions to set
the OCP test mode, store and run the test.
Over Power Test (OPP Test)
An OPP test automatically steps the current from a start power (PStAr) to stop power (PStOP) in equal
increments (PStEP). When the voltage falls below a threshold voltage (Uth), the test stops and the
power setting is saved.
Each press of the LIMIT key steps through settings for the four setup parameters.
After setting the four parameters, set the OPP test mode, store and run the test.
Test Mode
Test modes are Normal, OCP and OPP. All modes except OCP and OPP are “normal” mode.
Press the LIMIT key until tESt appears on the display. Use the inc/dec arrows to set Normal, OCP or
OPP modes.
If OCP or OPP mode is selected, store the setting in the chassis memory as described in the SLM-4 or
SLM-1 programming manuals.
To run an OCP or OPP test, perform a recall operation where the test was saved (see SLM-1 or SLM-4
manual).
To return to Normal mode, press the LIMIT key until tESt appears on the display. Use the down
arrows until “nor” appears on the display.
Please see Figure 3-3 for flowchart.
