Sorensen SLH-Series DC High Power Electronic Load Operation
3.5.1 EDIT Mode
To enter the EDIT mode of the Sequence function, press State3 + State4 keys
simultaneously (State 3 and State 4 LEDs are On, indicating Auto Sequence function is now
active). Use the BANK Up/Down keys to select the sequence to be edited, then press the
STORE key to begin the editing process.
The EDIT MODE flow chart is described below:
• Nine Auto Sequences (n1-n9) can be edited within the SLH mainframe.
• Each Auto Sequence has up to 16 test steps, where each step is pulled from any one of
150 Stored memory sets (30 Bank memory locations in each of 5 State locations).
• Each test step has t1 (test time, or duration of test step) and t2 (delay time), the unit of
time is 100mS, the range is 0.1S - 9.9S in 100mS resolution. SLH mainframe will check
each module GO/NG at the end of t1 (test time), the next step will be started after t2
(delay time).
• The test step sequence can include up to 16 steps, and can be terminated by pressing
the EXIT key (State 2) if fewer than 16 steps are required.
3.5.2 TEST Mode
To enter the TEST Mode of Sequence function, press State 3 + State 4 keys simultaneously;
(State 3 and State 4 LEDs are On, indicating Auto Sequence function is now active). Use the
BANK Up/Down keys to select the sequence test to be run, then press the START key to run
the test sequence.
• After pressing the START key, the SLH mainframe controls all the installed modules to
recall the memory correspond to the memory stored in Auto-sequence (n1~n9).
• Each test sequence starts from (Step 0 - t1 - t2), then (step 1 - t1 - t2), and so on until
either it completes the last step or is stopped by pressing the EXIT (State 2) key.
• The two-digit BANK LED will display “GO” (flash) if all test steps in all modules pass, and
will show “NG” (flash) if there is at least one failure during the test.
• At that point, the user can either press the Start key to continue with another test, or
press EXIT (State 2) key to quit the Auto-Sequence function.
