Home Forums General Discussion Technical Questions KCM 831 Hydro

I have a KCM 831 Hydro that is logging a F 14 fault. Does anyone know the proper procedures to do a valve learn and then a hoistway learn? Also, where I could find an adustment manual?

Where do you work? City, state?

Central Florida

I'll PM you something tomorrow

Great! Sure do need some help!

So sorry about the delay.

I PM'd you some stuff.

Do you get your hands on the info to enable you to perform hoistway learn as well as adj procedures. i have a monospace that so far has a bad drive, adon 2, and opt card. (Over 10k w exchanges so far) Have fault codes, prints and inspectors manual but looking for adj manual. Any help will be appreciated.

Sounds like you got more stuff than I got!

This is the most flaky equipment I've ever worked on. So many glitches, such lousy quality, such incredibly expensive parts, especially circuit boards. ($40,000 for an MX20 flat motor!)

Just a bloody shame....

welcome to the world of new proprietary equipment. elevators installs low replacement parts expensive.

wait until the brakes start to go...$$$

Set the car just below the bottom terminal on inspection ( 61N-low 30 and 61U HI.

make sure the valve is adjusted.

do a shaft setup reset. Menu 6-16 set to 4 then select.

do a shaft learn. Menu5-2 set to 1 then select then put car on auto.

return car to bottom terminal. Put the car on inspection. Do a learn mode. Menu 5-5 set to 1 then select then put car on auto.

Kone may have the perfect business model with this stuff....

Design a turd. Put in loads of them, and make all your money in parts..LOL..

we have a monospace that kept on faulting with i think edo faults coming up. lift would stop above or below level all the time but we would never actually catch it. it was also never stuck with passengers plus only happened at bottom and 2nd(of 4)floors. we went thru all range of things and just couldnt find it, cleaned tacho, adjusted brakes etc. we have an ex kone guy and he couldnt fix it either plus the controller had done its time and locked out. it ended up being after alot of spit balling/trial and error to be the load weigher on the standing ends. we added some test weights to the top of car and it hasnt faulted since!

Did you adjust the load weigher to "0" with the car on the top floor. They are very sensitive. I usually check and readjust all of mine every 6 months

gidday self, no we dont have a test tool/ dont know how to.im pretty sure the controller has locked its self out after so many runs.its 1 of the reasons we had such a long time to diagnose the problem. im not really familiar with kone gear.

Is this a four too one car ? Or I think they call it a Ohio car ?

hi fate. i dont think so(i may be wrong) but i think it would be 2 to 1 underslung car monospace.

I would be very careful adding weights to the top of this equipment. It is pure garbage and cheaply made. anytime I need to be on the car top I move around with great caution as I hear the crackling noise of the sheet metal beneath my feet.
Also... no test tool needed. Everything is done through the controller using your fingers and the led display.

If you have a load weigh strain gauge on the hitch plate that's connected to a LCEVTC board in the controller load weigh set up is straight forward.

Old style VTC board with no jumpers.

1. Empty car at hatch center, adlust offset pot on the VTC until the display in menue 5-1 reads 0.

2. full load at hatch center adjust the gain pot on the VTC until the display in menue 5-1 reads 100.

You may need to do this 2 or 3 times to get a stablelized reading.

New style VTC board with jumpers.

1. Empty car at hatch center, adjust offset pot on VTC board until display in menue 5-1 reads 0.

2. If you can't reach 0 and the reading is negative set X1 to the 1-2 position and X2 to the 2-3 position. If it's still negative set X2 to the 1-2.

3. If you can't reach 0 and the reading is possitve set X1 and X2 to the 2-3 position.

4.50% load at hatch center, adjust the gain pot on the VTC until the display in menue 5-1 reads 50

5. You may need to do this 3 or 3 times to get a stablelized reading.

6. If you can't get a reading within 5% you may need to equalize the hoist ropes.

New style VTC board with V3F25S drive

1. Connect a meter between LWD(+) and AGND(-)on the HCB board.

2. Empty car at hatch center, Adjust OFFSET potentiometer on VTC
board until LWD-AGND reads 1.0 +/-
0.2 VDC.
If unable to reach 1 volt using OFFSET
potentiometer, use X1 and X2 jumpers
to change range of OFFSET
potentiometer as follows:
� If reading remains less than 1 volt
set X1 to 1-2 and X2 to 2-3. If still
less than 1 volt set X1 to 1-2 and
X2 to 1-2.
� If reading remains greater than 1
volt set X1 to 2-3 and X2 to 2-3.

3. Select UI menu 6-74, set value to -1
and press SELECT. This resets loadweigh

4. Press menu button once, display shows 6-74

5. Press select once, set value to 0 and press select, display will be flashing between 6-74 and 0.

6. Press menu once. display will show 6-74

7. 50% load on car at hatch center.

8. Adjust gain pot on the VTC board until the meter reads 2.5 VDC.

9.Press select once. Display should show 6-74-0.

10. Set value to 50% in kgs.

11. Press select once. Display should be flashing between 6-74 and 0.

12. Press menue button once. Display shows 6-74.

13. Scroll to menu 6-99 and make the value 1 then press the select button. this saves the loadweigh adjustment.

14. Go to menue 5-1 and if all went well it should read 50 to indicate 50% load on car.

15. Take weight off and 5-1 slould read 0 to indicate empty car.
