Bulletin No. 50006-519-01BDecember 1996Chapter 6 — Class 8839 ALTIVAR 56 Combination DevicesPower Circuit W Combination PackagePOWER CIRCUIT WCOMBINATIONPACKAGEOperator Controls –General Arrangement andOperationAdjustable Speed OperationFreeze/Fire Stats Interlocks(if used)MOD B07Group 2 Pilot Light Cluster(if used)MOD C07Line Isolation Contactor(if used)The Combination Package is designed for running the motor strictly from thepower converter. The Combination Package consists of line fuses, 120 V fusedcontrol transformer (when control options are present), motor circuit protectordisconnect with means for locking in the open position, and a Hand-Off-Autoswitch with manual speed potentiometer.Operator controls are located on the front of the BELE box cover unless option D07is included. Option D07 omits the Hand-Off-Auto switch and manual speedpotentiometer, and no operator controls are present on the BELE box cover. If optionB07 is included, a pilot light cluster is also present on the front of the BELE box cover.The Hand-Off-Auto switch and manual speed potentiometer control the operationof the power converter which is factory configured to operate in terminalcommand mode.To operate the controller, the controller disconnect switch located on the front ofthe BELE box must be in the closed position. There are three modes of operationwith the Hand-Off-Auto switch: Hand, Off, and Auto.Hand mode is for local control. As soon as Hand mode is entered, the powerconverter is placed in running mode. In Hand mode, the speed potentiometermounted on the BELE box is used to control the speed of the controller.Off mode commands the power converter to stop the motor by either following theprogrammed deceleration ramp (factory setting) or by freewheel stopping.Auto mode is for remote control. In Auto mode, the power converter is placed inrunning mode as soon as a user-supplied run contact is closed between controllerterminals TB5 and TB8. In Auto mode, motor speed is varied by adjusting the usersuppliedauto speed reference signal (4-20 mA) supplied to the terminals TB13 (+),TB11 (-), and TB12 (Shield) in the BELE box. Refer to Chapter 5 for scaling of thissignal.Terminals TB4 and TB5 are dedicated terminals for accepting a user-suppliedfreeze/fire stat interlock (normally closed). The power converter will stopoperation if the connection between TB4 and TB5 is opened. Remove the factoryjumper wire located on these terminals before installing interlock.This pilot light cluster provides visual indication of protective functions and circuitstatus. Listed below are the four pilot lights provided and their functions.1. Power On (Red): illuminates whenever mains power is applied to thecontroller. The LED is rated 120 V.2. AFC Run (Green): illuminates whenever LO1 is high (programmed forrunning state) to annunciate a drive run condition. The LED is rated 24 V.3. Auto Mode (Green): illuminates whenever the drive is running in the Automode. The LED is sequenced by the Hand-Off-Auto selector switch and israted 24 V.4. AFC Fault (Yellow): illuminates whenever LO2 (programmed for fault state)is high to annunciate a drive fail condition. This light is normally not lighteduntil a controller protective circuit has caused an abnormal shutdown. TheLED is rated 24 V.MOD C07 provides a line isolation contactor factory wired between the line fuses(FU1, FU2, and FU3) and the power converter (L1, L2, and L3). An Open-Close switchis provided on the controller door for controlling the contactor. The line isolationcontactor is energized whenever the Open-Close switch is in the closed position.© 1996 Square D All Rights Reserved139ηττπ://νιχοντρολσ.χοm

It is used when the user prefers to supply external control devices.There are a number of ways to sequence the operation of the power converterwhen the Hand-Off-Auto switch and manual speed potentiometer are not present.Figures 79 - 82 show recommended sequencing diagrams for commonly usedcontrol methods.Figure 79 can be used for applications in which the power converter start/stopoperation is controlled by a user-supplied Auto contact, and the speed is controlledby a user-supplied 0 - 10 VDC speed reference signal.0 - 10 VDC Signal+–TB10(AI1)TB11(COM)Remote 0 - 10 V Speed SignalAuto Start Contactor Jumper **TB12(S)TB6(LI2)TB16TB4FreezestatTB5* Jumper(+24 V) (LI1)Figure 79: Speed Reference #1 Signal (0 - 10 VDC) OnlyFigure 80 can be used for applications in which the power converter start/stopoperation is controlled by a user-supplied Auto contact, and the speed is controlledby a user-supplied 4 - 20 mA DC speed reference signal.4 - 20 mA+–TB13(AI2)TB11(COM)GNDTB12(S)TB7Remote 4 - 20 mA Speed SignalTB8(LI4)*Jumper(LI3)TB16 * JumperTB26Auto StartTB5(LI1)*JumperTB4*Jumper(+24 V)TB27Figure 80: Speed Reference #2 Signal (4 - 20 mA) OnlyFigure 81 can be used for applications in which the power converter start/stopoperation is controlled by a user-supplied Auto contact, and the speed is controlledby a user-supplied remote speed potentiometer.140 © 1996 Square D All Rights Reservedηττπ://νιχοντρολσ.χοm
