EVERY Monday morning at approx 4 am. And Now randomly during the week.
I have 4car group shutting down at the same time with a Fault 10 FC Faultā¦ we have had The building install a temporary voltage monitor for over a month and no power issues showed up..
I have changed all the LON and COM boards and swapped Gateway boards with no change.. I guess I can start swapping GCIO boards?
I have spent countless hours trying to diag..
The only thing that works isā¦wait an hour or so, go eat lunch Come back and the damn things will work no issues!! 🤬They will start working without doing ANYTHING..
They will start working as I am trying to diagnose them.
I think I have them fixed but Noooo. EVERY Monday at 4 am they will fault out again. All the fault 10..
ANY ideas guys? Iām all out of ideas and so are the adjusters.🙏
Weirdly enough, years ago I had a group of trouble free Swift FUTURA cars that were adversely affected by a recently installed rooftop antenna (leased out rooftop space) that got its signal wires routed in a chase adjacent to the hoist way right where the DPP transducer was positioned on the crosshead. Somehow that close proximity of radio interference caused all kinds of issues.
What is the Fault 10?
converter
caused
an
emergency stop.
VEC monitors SH contractor. If safety circuit opens, PVEC can detect this event before Travel Control does. Therefore,
this event
can also be caused by a safety circuit problem
See measures and comments for SH_FAULT.
Actions to be taken:
- Look at Motor Control Event Log.
I have replaced SH contractor on all 4 units. No issues with the safety circuit. Believe me Iāve made sure all plugs are seated and wiggled every wire I can find trying to duplicate or prevent the problem.
If one faults out and shuts down. They ALL fault out and shut down
Is so, disconnect the input signal or fuse that controls that input.
Is this a new problem on the existing group?
Any new construction additions to the building?
āFrequency Converterā fault sounds like incoming power especially as it affects all cars. Unless itās only the group controller that takes a momentary dump. Building Engineer doesnāt know of any changes regarding power like upgrading main switching gear etc?
Whose equipment is this?
Itās been happening for years but only happened a couple times per year. Now itās every week sometimes several times a week.
There is remodeling going on almost year round. Several floors have been completed recently.
I can disconnect emergency power connections easy Iāll try that now
Itās Schindler Txr5 controllers
No upgrades to main switchās
Does the building use card readers or some other security feature? I only ask because they do interface with the group PB riser(s) and Fire Service which would affect all cars.
Just thinking out loud and your ass is probably pretty sore by now so we want that to end as well.
🤬 All 6 units went down at the same damn time this morning at 1am
They do have card readers.
They all connect to a LON16 board inside each controller.
I can start looking at that circuit.
Thank you for the response
The clues are;
All cars affected
Early in the morning
Becoming more frequent.
Resets themselves which is super weird.
So hereās a thought;
With the building engineer or managers approval, shut off Car 1. See what happens. Just leave it off (not on inspect or test mode but mainlined off) and let the other three handle dispatching. If the same outcome, try Car 2 etc until youāve proven itās not one car out of the four somehow pulling the group down. Could the Car thatās dispatcher, if it crapped out, send the same āFault 10 crap outā command to the others in the group? I dunno.
Iām wondering about a group or individual car power supply issue where the voltage drops below or right at the operational threshold due to a flakey PS adjustable pot for CPU functions. Or-
Is there an adjustment on the drive whereby you widen the time frame on this frequency fault 10 to offset false triggers or give more time before declaring the fault? Theyād all be set at the same default value Iād imagine.
And that Fault 10ā¦itās the only logged fault with the same time stamp on each car each time right?
I have shut all units down and tried to focus on just one.
I worked on it all damn day today.. never could get it to come back up. Itās getting worse
Iāve checked all power supplyās and adjusted to 24.5 volts
And monitored voltage as the fault and shutdown happens.
We are having electrician install voltage and amp monitors again for a couple weeks.
The Drive throws an error 733 which is a ācurrent mains differentialā error. Itās just very odd it shuts down a 4 car group AND the same 2 cars in a different 3 car group like clockwork mondays between 1 and 4 am 😤🤬
This is just flat weird.
I canāt find that thread. But Iāll keep searching
