WESTINGHOUSE INFORMATION

Nancy's Westinghouse Contribution

WESTINGHOUSE DMR CHEAT SHEET for Standby Mechanics
Relay numbers = [00] Relay functions = function
SAFETY & LOOP. Safety Circuit: [29] + [90] Governor= [55]Genereator= [5] Loop = [7] Start= [80] + [80A] Run, Gen = [65]+ [11]
(if [11A] is out, bad tach gen)
Running Relays: [65], [23], [30], [33], [32L] Anti-stall = [AST] (saves HM if car stalls in leveling)( #73 to #76 jumps out limits if car is in overhead or pit)
DOOR RELAYS: [45]: up=closed, out=open [70]: out=closed, up=open (electrical interlocks)[40] + [C4N]= car gate [41]= hall door locks Electric Eye= [STRP, STRB]
Door Open = [44] Door Close = [43]
INSPECTION & INDEPENDENT SVC. Insp = [60] . Ind = [TRA], [TRB], [TRDA], [TRE] & [980M]
All relays with “FE” = Fire Recall Circuit
To run on inspec. disable doors w/ sw on controller, put car on inspec, hit {81U] or [81D]
DIRECTIONS. Up= [1] Down= [2], Brake Aux Up= [3], Brake Aux Dn=[4] [81U] & [81D] are Aux. Directions prior to [1] or [2] Bottom normal Limit= [B69] Top Normal Limit= [T69] Terminal Slowdown= [TSD]
BRAKE = [BK] Microswitch on Brake = [A]
LEVELING. Level =[L] Leveling Relays= [L1], [L2}, [L3] [34]= Initiates conductors to bring car into floor[SCL]= Selector clutch [SEL] = Selsen Unit
How to count Westinghouse contacts: on small relays:With nut & bracket of relay on left of two horizontal rows of contacts, count contacts left to right --
Bottom Row counts: 11,12,13,14 Top Row counts 21,22,23,24
