BOP HIPWR 111315 3-173.3.4.1 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 allow-able for voltage and current. The default software limits are determined by the model: the nom-inal (rated) values for voltage and current (e.g., 36V and 28A for the BOP 36-28MG). These fourvalues 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,TABLE 3-5. MAX/MIN SETTINGS MENUSETTING CHOICES(BOLD = Factory Default) FUNCTIONProtect Entry BIPOLARINDEPENDENTBIPOLAR - 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 thefront panel.
