Swift 5000 Drive Faultsgreenspun.com : LUSENET : Elevator Problem Discussion : One Thread
I have a Swift 5000 car that has oversped twice in both the up & down directions tripping the gov. The only resulting error code was a 58. When I run the car on inspection or in automatic I get an intermittant drive fault with error 58 & 13. CEC has had me swap out UR & DR modules, the PMI board, the tach, and now the GVI board. The car will run fine for about an hour then go into drive fault again. Any thoughts?

Does the car over speed on inspection? Have you reset up the reg board? How about motor fields? Geared or gearless, Speed? Is the fault generated by the DAR board or the CPU? Has any work been done to the generator? Did you check DPP sensor or the tape guide's.

Rob, The car does not overspeed on inspection but, has occasionally run in the wrong direction causing error 13's. The speed reg board adjusments check out as does the field reg. board. This is a 500fpm scr job. Tried swapping Dar board & GVI board. The DPP sensor, DPP output module and tape guides are ok. Got my hands on a scope and have been monitoring speed ref. and tach feedback signals. Tach feed back signal has shown anomalies when checking on the reg. board but not where the signal enters the drive. That leaves a interface board or reg. board problem.

Found an intermittant problem with the 12 SCR controller board. (LouisAllis/Magnatek drive)Occasionally in the up direction, there was no regeneration, allowing the overspeed. Ocassionally, SCR's did not fire when starting in down direction, allowing the car to drift up and cause the error 13's.
