Sorensen SLM-1 Chassis Operation
3.3
STORE / RECALL FUNCTION
The eight function keys on the front panel of SLM chassis are designed for high
throughput testing. There are 30 banks (only one bank for AC modules) of 5 operation
states for a total of 150 testing steps that can be stored in EEPROM memory. Each
state can save or recall the load status and level for the load module. For more detail
about the STORE and RECALL functions, refer to the operation flow-chart in the
applicable SL-Series Electronic Load Module Operations Manual.
3.3.1 STORE Procedure
1. Set the load status and load level for the load module within the chassis.
2. For AC loads, go to the next step in this procedure. For DC load modules,
select the Memory Bank (01-30) for storing the load status and level.
3. Press the STORE key on the SLM chassis, the STORE LED begins flashing
to indicate ready to store. Either press a State key (next step in this
procedure), or Exit by pressing Store key again or by waiting 20 seconds, at
which time the STORE LED will turn off to prevent accidentally overwriting a
memory state.
4. Press one of the State 1-5 keys. The appropriate State key's LED will light
immediately; the load level and status of SL-series load module is now stored
into the EEPROM memory. The STORE procedure is completed when the
STORE LED turns OFF.
Notes:
If more than one state is stored in the same State key, the last one entered will
be treated as an update and will overwrite the previously input state.
After pressing the STORE key, the front panel keys on the SL-series electronic
load module are still active. However, the STATE LED will turn off if any key on
the load module is pressed. This indicates that the front panel state of the load
module is not the same as stored state.
3.3.2 RECALL Procedure:
For SLM AC Series
Press one of the Memory State 1 through 5 keys; its corresponding LED lights,
and the stored state on the SLM chassis is sent to the module. If any key is
pressed on the load module, the State LED indicator turns off immediately to
indicate that the module state no longer matches the recalled state.
For DC Loads
Use BANK up and down keys to select the Memory Bank, then press one of the
Memory State 1 through 5 keys; its corresponding LED lights, and the stored
state on the SLM chassis is sent to the module. If any key is pressed on the load
module, the State LED indicator turns off immediately to indicate that the module
state no longer matches the recalled state.
