Home Forums General Discussion Technical Questions Kone KCM 831 Emergency Stopping

I'm either completely lost or overthinking an issue I've got going on.

I've got a 2-1 car that is stopping suddenly when it passes the 136n (ETS) magnet. The car throws 101, 126, and 210x (whichever one is fault not present long enough to track.) car stops suddenly, then levels in a few seconds later and goes back in service. Is this an ETS stop or something else? I assumed it was going too fast and thought about doing a decel and etsl learn, but have no documentation on how to do that.
Another mechanic suggested changing the tach which has been done.

Thanks, and any help is appreciated.

hello. you can check the fault log by scrolling through the menu to E - 1. If its panic stopping, im guessing the fault is 217. How fast is the car and which drive do you have? Does it do this every time going to the bottom floor or just intermittently? Did it just start or has it always done this?

Some things you might check:
Connections on 377 XNT1 plug
ADON XH23 plug
NTSL board field connections
5:1 displays current load weigher %. Should be near 0
6:7 should be 2 if you have 2:1 roping

Get on top of your car and do the sideways jig around the bottom floor in a few places. Make sure there isnt excessive postwise slop. The car could be pulling away sometimes enough to miss the switch.

Disable hall calls and door opening by flipping the 2 switches on the cpu board. 4:21 - 1 sets the car to run top floor bottom floor repeatedly. then you may turn 4:30 - 1
to see the current car speed read by the ADON board. It will be in cm/s so you'll have to convert that to fpm. 178 cm/s is 350fpm 258 cm/s is 500fpm ect. You can see if the car is actually overspeeding when it panic stops. On one of the back pages of your prints you should have a table where you can check your ETSL switch settings

if you PM me your email I can send you some information.
