BOP HIPWR 111315 3-25If the reference type is ExtRefLvl (instead of Internal or External), the uppercase V or A isreplaced by lowercase v or a. The protection setting is listed under the Prot heading.If External mode was saved, the protection setting is followed by C, indicating that the mode(voltage or current is Conditioned by the external signal applied to pin 2 of the Analog I/O Port(see Table 2-10).If the protection setting is followed by a minus sign (–) it indicates that the negative protectionvalue (displayed) is set larger (absolute value) than the positive protection value (not shown onthe list). Similarly, if the protection setting is followed by a plus sign (+) it indicates that the posi-tive protection value (displayed) is set larger than the negative protection value (not shown onthe list).If Main channel reference was saved as External, EXT is listed under the Main heading. In thiscase the main channel reference uses the external voltage applied to pin 11 of the Analog I/OInput Port (see Table 2-10).If Protection type was saved as External, EXT is listed under the Prot heading. In this case theprotection settings are determined by the levels applied to the appropriate pins of the Analog I/OInput Port (see Table 2-10). If the main channel is voltage, the protection settings are deter-mined by pin 5 (negative current protection) and pin 13 (positive current protection). If the mainTABLE 3-8. SAVE/RECALL MENUPARAMETER CHOICES(BOLD = Factory Default) FUNCTIONNOTE: DEFAULT values for empty cells are the settings of the unit at the time the save/recall menu is entered.MODE VOLTCURRENTEXTERNALVOLT - Selects voltage mode. Voltage value determined by SETTING.CURRENT - Selects current mode. Current value determined by SETTING.EXTERNAL - Used for customized configuration where EXT VM/CM signal at pin2 of I/O port controls mode; consult factory for details.MAIN CHANNELREFERENCEINTERNALEXTERNALEXTL REF LVLINTERNAL: Any external reference applied to the Analog I/O port pin 11 is ignoredand the internal reference established by SETTING field.EXTERNAL: The internal reference is ignored, and the external reference appliedto the Analog I/O port pin 11 is used (see PAR. 3.4.3.1).EXTL REF LVL: Allows the gain of the BOP to be established by the maximumoutput voltage or current introduced by the SETTING field. (see PAR. 3.4.3.2).SETTING nn.nnn ornnn.nnn(model and parameterdependent)Sets the active channel setting. E.g., if VOLT mode is selected, nnn.nnn is voltagesetting, if CURRENT mode is selected, nn.nnn is current setting. If EXTERNALmode is selected, SETTING is not available.PROTECTIONMODEINTERNALEXTERNALLESSER LIMITINTERNAL - Allows limits to be controlled by POSITIVE and NEGATIVE values.EXTERNAL: Allows limits to be controlled by analog signals applied to the analogport (see PAR. 3.4.4).LESSER LIMIT: Allows protect limit to be automatically selected from either 1) theexternal analog voltage applied to the Analog I/O port or 2) the value set in thePOSITIVE and NEGATIVE fields. Whichever limit has a lower absolute value(closest to zero) has effect (see PAR. 3.4.4).POSITIVE nn.nnn ornnn.nnnThis is the positive value for Voltage protect if CURRENT mode is selected, or thepositive value for Current protect if VOLTAGE mode is selected. If EXTERNALmode is selected, this field is not accessible.NEGATIVE nn.nnn ornnn.nnnThis is the negative value for Voltage protect if CURRENT mode is selected, or thenegative value for Current protect if VOLTAGE mode is selected. If EXTERNALmode is selected, this field is not accessible.OUTPUT OFFONOFF - Output disabled. The behavior of the unit when output is disabled dependson the LOAD TYPE setting (see PAR.3.3.6).ON - Output enabled.
