Sorensen SLM-Series DC Load Operation
M540071-01 Rev C 3-11
3.2.3 Normal Operating Modes
In the following instructions, the numbers within parentheses refer to the front panel
components of the SLM-series DC plug-in-module, as labeled in Figure 3-1.
CC Mode
CC mode can be either static (fixed DC level) or dynamic (two levels with timing and slew rates
programmed). Dynamic mode is described later in this Section 3.2.3. In static mode, two
levels can be set to allow for quick switching between two current levels.
1. Press the MODE key (3), until the CC LED (3) is lit.
2. Press the PRES key (7) to view the programmed values. The high level must be higher
than the low level; the load will not allow the HIGH level to be lower than the LOW level.
a. To set the high level, press the HIGH key (16). Use the inc/dec arrows to set the
desired level.
b. To set the low level, press the LOW key (16). Use the inc/dec arrows to set the desired
level.
3. To exit the Preset mode, press the PRES key until its LED is green (power/watts displayed)
or not lit (volts displayed).
4. Press the LEVEL key to select the desired level CC mode by. When the LEVEL LED is lit,
the HIGH level is selected and when not lit, the LOW level is selected.
5. Press the LOAD key (8) to toggle the load off or on. Press the LEVEL key at any time to
switch between the HIGH and LOW level settings. The value for current can be changed at
any time using the inc/dec arrows. The values set can be viewed by pressing the PRES
key.
CR Mode
CR mode static (fixed DC level) can be set in two levels to allow for quick switching between
two resistance levels. High and low levels are referenced to the resulting current level, thus
the ×↑keys will decrease the resistance setting and the Ø↓ keys will increase the resistance
setting.
1. Press the MODE (3) key, until the CR LED is lit (3).
2. Press the PRES key (7) to view the programmed values. The HIGH level must be set to a
lower resistance than the LOW level; the load will not allow the HIGH level to be higher than
the LOW level.
a. To set the high level, press the HIGH key (16). Use the inc/dec arrows to set the desired
level.
b. To set the low level, press the LOW key (16). Use the inc/dec arrows to set the desired
level.
3. To exit the Preset mode, press the PRES key until its LED is green (power/watts displayed)
or not lit (volts displayed).
