ALLEN-BRADLEY ALLEN-BRADLEY BULLETIN 1336 MOD-L3 INTERFACE GROUNDED/UNGROUNDED APPLICATION NOTE #12 January 2, 1997 PURPOSE The purpose of this document is to provide guidelines for wiring and control schemes for the Bulletin 1336 AC Drive. This document is to be used as a suggestion only. Users must ensure that installations meet applicable codes and are suitable for the existing conditions. The Bulletin 1336 User Manual should be used as a reference to ensure that proper wire selection,routing,and fusing guidelines are followed. WHAT THIS NOTE CONTAINS The Bulletin 1336-MOD-L3 Logic Interface may be used on a grounded or ungrounded 120VAC supply. INTENDED AUDIENCE This application note is intended to be used by personnel familiar with the hardware components and programming procedure necessary to operate the Bulletin 1336/1336VT. WHERE IT IS USED The diagrams, parameter settings, and auxiliary hardware used in this application note are designed to address specific issues in many different applications. Some changes by the Users may be necessary to apply the concepts of this document to a specific application. DESCRIPTION GROUNDED 120VAC The MOD-L3 internal circuitry of the system, it is recommended secondary be fused. Refer Interface is isolated from the drive. For a grounded 120VAC that only the "hot" side of the to figure 1 for the diagram. UNGROUNDED 120VAC When a 120VAC supply does not have a grounded secondary, fuses are required for both the "hot" and "common" legs of the transformer. Refer to figure 2 for the diagram. APPLICATION The transformer and fusing selected for the 120VAC power 1 ALLEN-BRADLEY CONSIDERATIONS input must be capable of supplying 8.5ma of current for each to the MOD-L3 Interface. 2 ALLEN-BRADLEY 115V AC INTERFACE WITH GROUNDED SUPPLY 460V AC 48-62HZ L1 L2 L3 115V AC TB1 TB2 1 POT HIGH 2 POT WIPER BULLETIN 1336 3 POT/SIGNAL COMMON 4 5 0-10V INPUT 6 4-20MA INPUT 7 PULSE INPUT (-) 8 PULSE INPUT (+) 9 5V METER OUTPUT 10 AT SPEED 11 AT SPEED/RUN COMMON 12 RUN 13 FAULT 14 FAULT/NOT FAULT COMMON 15 NOT FAULT 16 ALARM 17 ALARM/NOT ALARM COMMON 18 NOT ALARM MOD-L3 115VAC INTERFACE TB3 START 19 START 20 STOP 21 COMMON 22 JOG 23 REVERSE 24 SW1 25 COMMON 26 SW2 27 SPEED SELECT STOP CUSTOMER INTERLOCK CUSTOMER INTERLOCK 28 AUX 29 COMMON 30 ENABLE TB1 M1 M2 M3 GND MOTOR FIGURE #1 3 ALLEN-BRADLEY 115V AC INTERFACE WITH UNGROUNDED SUPPLY 460V AC 48-62HZ L1 L2 L3 115V AC TB1 TB2 1 POT HIGH 2 POT WIPER BULLETIN 1336 3 POT/SIGNAL COMMON 4 5 0-10V INPUT 6 4-20MA INPUT 7 PULSE INPUT (-) 8 PULSE INPUT (+) 9 5V METER OUTPUT 10 AT SPEED 11 AT SPEED/RUN COMMON 12 RUN 13 FAULT 14 FAULT/NOT FAULT COMMON 15 NOT FAULT 16 ALARM 17 ALARM/NOT ALARM COMMON 18 NOT ALARM MOD-L3 TB3 START 115VAC INTERFACE 19 START 20 STOP 21 COMMON 22 JOG 23 REVERSE 24 SW1 25 COMMON 26 SW2 27 SPEED SELECT 28 AUX 29 COMMON 30 ENABLE STOP CUSTOMER INTERLOCK CUSTOMER INTERLOCK TB1 M1 M2 M3 GND MOTOR FIGURE #2 4
