Bulletin No. 50006-519-01BDecember 1996Chapter 6 — Class 8839 ALTIVAR 56 Combination DevicesPower Circuit Y Bypass PackageMOD A07Group 1 Pilot Light Cluster(if used)MOD B07Group 2 Pilot Light Cluster(if used)MOD C07Line Isolation Contactor(if used)MOD D07Omit Hand-Off-Auto Switchand Manual SpeedPotentiometer (if used)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. Bypass Run (Green): illuminates whenever the bypass contactor coil isenergized and the motor is running from line power. The LED is rated 120 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.This pilot light cluster provides visual indication of protective functions and circuitstatus. Listed below are the four pilot lights provided and their functions.1.

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 Auto mode.The LED is sequenced by the Hand-Off-Auto selector switch and is rated 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). The line isolationcontactor is energized whenever the AFC-OFF-Bypass switch is in the AFC position.MOD D07 omits the Hand-Off-Auto selector switch and manual speedpotentiometer. 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 83 - 86 show the recommended sequencing diagrams for commonly usedcontrol methods.The diagram shown in Figure 83 can be used for applications in which the powerconverter start/stop operation is controlled by a user-supplied Auto contact, andthe speed is controlled by a user-supplied 0 - 10 VDC speed reference signal.© 1996 Square D All Rights Reserved143ηττπ://νιχοντρολσ.χοm
