3.3.12 STORING POWER SUPPLY OUTPUT SETTINGS
The programmed settings of voltage, current, overvoltage protection and overcurrent protection
can be stored in one of the 40 memory locations available for local programming (see PAR.
3.3.14).
With the power supply in command entry status , press STORE key. The LCD reads
STORE
mem nn
where nn is the memory location where the settings are to be stored. Press ENTER
or CLEAR to exit without changing setting. Enter memory location (from 1 to 40) and press
ENTER. The programmed voltage, current, overvoltage protection and overcurrent protection
settings in effect when ENTER is pressed are stored in the selected memory location. To recall
stored settings, see PAR. 3.3.13
3.3.13 RECALLING STORED OUTPUT SETTINGS
With the power supply in command entry status , press RECALL. The LCD reads
RECALL
mem nn
where nn is the memory location holding the settings to be retrieved. Press ENTER
or CLEAR to exit without changing setting. Enter memory location (from 1 to 40) and press
ENTER. The stored settings for voltage, current, overvoltage protection and overcurrent protec-
tion replace the current values, and the unit returns to command entry status.
3.3.14 LOCAL MODE PROGRAMMING OF THE POWER SUPPLY.
Local mode programming offers the user 40 memory locations that can be used to program the
power supply. Each location defines values for output voltage, output current, overcurrent pro-
tection, overvoltage protection, time duration (between 0.1 and 300 seconds) for the pro-
grammed settings, and the address of the next memory location in the program.
NOTE: When programming sequential voltage levels, it is important to set the Overvoltage to
accommodate the highest voltage of the sequence. Otherwise, when going from higher
to lower voltage levels, the overvoltage protection will trip and shut down the unit
because the overvoltage setting registers faster than the power supply can attain the
lower voltage.
3.3.14.1 CREATING OR MODIFYING A PROGRAM (PROGRAM EDIT MODE)
Creating a program and modifying an existing program are identical except that a program mod-
ification requires only selected parameters to be changed rather than all new parameter values.
With the power supply in command entry status , press EDIT PROG key. The top line indicates
the
STARTaddr. nn
, where nn is one of 40 memory location. To select a different address,
enter new value and press ENTER.
The top line of the LCD indicates the active memory location, e.g.
ViewVAL Mem
where n
is the memory location previously chosen. The bottom line of the LCD indicates the parameter
on the left
(Iset
,
Vset
,
OVset
,
OCset
,
TIMEval
,
NEXT STEP
), the parameter’s value on the
right, and data entry status in the middle. To modify time values see PAR.3.3.14.1.1.
Press ENTER to accept displayed value, or enter new value and press ENTER to accept new
setting (the LCD displays the next parameter). Press CLEAR to exit Program Edit mode without
changing value. Use
or key to scroll forward (or backward) to view next (or previous)
parameter or memory location. For a program to run once, then stop, see PAR. 3.3.14.6; to
cycle a program continuously, see 3.3.14.4. After all program values have been set, press
CLEAR or ENTER to exit Program Edit mode. Setting up a program can be made easier by
copying the Memory Location Worksheet (Table 3-3) and filling in the values before program-
ming the power supply.
