Chapter 6 — Class 8839 ALTIVAR <strong>56</strong> Combination DevicesBulletin No. 50006-519-01BOperation Sequence & Options December 1996SEQUENCE OFOPERATION ANDOPTIONSTerminal Command Modevs. Keypad Command ModeThis section describes basic sequences of controller operation for the three preengineeredpower circuit configurations and available options. The options are:• Power Circuit W: combination package• Power Circuit Y: bypass package• Power Circuit Z: remote starter bypass packageIn order for factory and/or user supplied pilot devices and controls to berecognized, the Class 8839 ALTIVAR <strong>56</strong> combination drive controller is factoryconfigured to operate in the Terminal Command mode. Switching from TerminalCommand mode to Keypad Command mode will disable power converter logicinputs. Factory and/or user-provided control devices will be ignored. For thisreason, do not operate the Class 8839 ALTIVAR <strong>56</strong> drive controller in the KeypadCommand mode.Consult the factory configuration listing on the applicable control circuit diagram(pages 151 to 1<strong>56</strong>), and refer to Chapter 5 before reprogramming logic inputs,outputs, torque types, or control types. Changing certain factory settings willadversely affect the performance of the Class 8839 ALTIVAR <strong>56</strong> drive controller.WARNINGUNINTENDED EQUIPMENT OPERATION• Controller has been factory programmed. Alteration of factory programming maycreate incompatibilities with supplied controller configuration.• Read and understand Chapter 5 as well as programming information on applicablecontroller schematics, Figures 91 - 96.• If the power converter unit is re-initialized using the TOTAL or PARTIAL FACTORYSETTING function, the power converter must be re-programmed per theprogramming instructions on applicable controller schematics, Figures 91 - 96.• If the power converter unit or the main control board of the power converter isreplaced, the power converter must be re-programmed per the programminginstructions on applicable controller schematics, Figures 91 - 96.Failure to observe these instructions can result in death, serious injury, orequipment damage.138 © 1996 Square D All Rights Reservedηττπ://νιχοντρολσ.χοm
