AMETEK SLM-4 - Manual (Page 22)

Operation Sorensen SLM-4 Chassis
3.2.1 Power-On Status
Local/manual operation displays:
STORE/RECALL: All LEDs are OFF; BANK LED display shows 01; SL-series
electronic load is in Power On initial state (please refer to the appropriate SL-series
Electronic Load Operations Manual for the startup state of each module).
GPIB address setting:
1. GPIB address is set by pressing STATE 4+STATE 5 simultaneously.
2. Press UP or DOWN on the BANK keys to select the address number (0-31).
3. Press STATE 2 to exit GPIB address setting mode.

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 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 four
electronic load modules simultaneously. 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 each 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 any load
module is pressed. This indicates that the front panel state of the load module is not
the same as stored state.
