FIGURE 3-15. ANALOG PROGRAMMING OF OUTPUT VOLTAGE OR CURRENT USING VOLTAGE
3.4.3 CHANGING OVERVOLTAGE OR OVERCURRENT PROTECTION VALUES IN ANALOG
PROGRAMMING MODE
Overvoltage and overcurrent values can not be changed using analog remote programming;
this can only be done by issuing a command via the GPIB or RS 232 port, or via local mode
from the front panel (enter local mode by pressing the VOLTAGE and CURRENT adjustment
controls at the same time, then see PAR. 3.2.11).
If the panel is locked and RS 232 or GPIB access is not possible, turn the power supply off, set
ANALOG I/O DIP switch position 5 to OFF, and then power up again to unlock the panel
(PAR.3.2.2.1). After the settings have been changed, turn the power supply off, set ANALOG I/O
DIP switch position 5 to ON to relock the panel, then turn on the power supply to restore Analog
Remote Programming (status display reads aRem).
