3.3.4.1 CHANGING MAXIMUM ACCEPTED VOLTAGE OR CURRENT (MAIN CHANNEL SOFT-
WARE LIMITS)
The software limits for the main channels (+Voltage Max, –Voltage Min, +Current Max and –
Current Min) are the maximum (positive) and minimum (Maximum negative) values allowable
for voltage and current. The default software limits are determined by the model: the nominal
(rated) values for voltage and current (e.g., 36V and 28A for the BOP 36-28MG). These four
values can be adjusted independently. For example, a BOP 36-28MG, capable of delivering
±36V in voltage mode can be configured to allow voltage to be adjusted only from –1V to
+15V by setting –Voltage Min to –1 and +Voltage Max to +15. Similarly, a BOP 36-28MG,

FUNCTION
Protect Entry BIPOLAR
INDEPENDENT
BIPOLAR - Causes a single protection limit value (one for voltage, one for cur-
rent) to apply to both ± limits. Only one value is displayed and edited from the
front panel. (see PAR. 3.3.3.1.)
INDEPENDENT - Allows + and – protection limits to be set independently. from
the front panel (see PAR. 3.3.3.1 for considerations when using remote mode).
VOLTAGE MODE
+Voltage Max (value)
+Eomax
Defines the maximum voltage level that can be set in voltage mode. Default =
Rated +Output voltage (e.g., for BOP 36-28MG, Eomax = 36). To modify, see
PAR. 3.3.4.1.
–Voltage Min (value)
–Eomax
Defines the minimum (maximum negative) voltage level that can be set in volt-
age mode. Default = Rated –Output voltage (e.g., for BOP 36-28MG, Eomax =
36). To modify, see PAR. 3.3.4.1.
+C Protect Max (value) model specific
up to Iomax + 1% of Iomax
Defines the maximum value for +Current Protect. To modify refer to 3.3.4.1.
+C Protect Min (internal value)
Not Adjustable
Defines the minimum value that +Current Protect can be set to. This is a calcu-
lated value and is not adjustable from the front panel.
–C Protect Max (internal value)
Not Adjustable
Defines the maximum (minimum negative) value that –Current Protect can be
set to. This is a calculated value and is not adjustable from the front panel.
–C Protect Min (value) model specific
up to Iomax + 1% of Iomax
Defines the minimum (maximum negative) value for –Current Protect. To modify
refer to 3.3.4.1.
CURRENT MODE
+Current Max (value)
+Iomax
Defines the maximum current level that can be set in current mode. Default =
Rated +Output current (e.g., for BOP 36-28MG, Iomax = 28). To modify, see
PAR. 3.3.4.1.
–Current Min (value)
–Iomax
Defines the minimum (maximum negative) current level that can be set in current
mode. Default = Rated –Output current (e.g., for BOP 36-28MG, Iomax = 28). To
modify, see PAR. 3.3.4.1.
+V Protect Max (value)
Eomax +1% of Eomax
Defines the maximum value that +Voltage Protect can be set to. To modify refer
to 3.3.4.1.
+V Protect Min (internal value)
Not Adjustable
Defines the minimum value that +Voltage Protect can be set to. This is a calcu-
lated value and is not adjustable from the front panel.
–V Protect Max (internal value)
Not Adjustable
Defines the maximum (minimum negative) value that –Voltage Protect can be
set to. This is a calculated value and is not adjustable from the front panel.
–V Protect Min (value)
Eomax + 1% of Eomax
Defines the minimum (maximum negative) value for –Voltage Protect. To modify
refer to 3.3.4.1.
