BATTERY . This mode is necessary for the power supply to function properly and safely with
either battery or constant-voltage-type active electronic loads. This mode prevents the battery
from discharging during the OFF state. When the output is disabled (set to OFF), the BOP will
go to current mode, current will be set to zero, with voltage protect and current limit set to maxi-
mum. In this way the battery will not be discharged while the output is OFF. For constant-volt-
age-type active electronic loads this mode stops energy flow during the OFF state. Table 3-6
indicates how the power supply responds to a command to go from Output ON to OFF.

modify. (If a Password is required, see PAR. 3.2.4.4 for instructions.) Highlight Active, Resistive
or Battery (see explanations and associated WARNINGS above) and press

to save. Then
press $ to save for power-up, # to abort, or % to apply the changes (without saving for
power-up) and exit. After configuring, the new setting will be effective when the power supply
goes from output on to output off.

3.3.7 CHANGING THE DEFAULT POWER UP SETTINGS
When the BOP is shipped, the following default settings are programmed to be in effect each
time the unit is turned on, however these defaults may be changed as indicated below;
• Mode: Voltage (may be voltage or current, see PARs. 3.3.2 and 3.4.2. Table 3-7 illus-
trates the relationship between Mode, Main Channel, Protection Type and Levels set-
tings.
• Main Channel: Internal (may be Internal, External, or External Reference Level, PARs.
3.3.3 and 3.4.3).
• Protection type: Internal (may be Internal, External, Lesser Limit) (see PARs. 3.3.3 and
3.4.4)
• Levels, Voltage and Current: maximum (see PAR. 3.4.4) Represents the power-up val-
ues for protection limit channels (bipolar limits), voltage for current mode and current for
voltage mode. Table 3-7 illustrates the relationship between Mode, Main Channel, Pro-
tection Type and Levels settings.
• Output: on (may be on or off) (see PAR. 3.3.5)
To change the default settings refer to the applicable paragraph(s) specified above as needed,
then from the power-up screen press
