Elevator Forum

ummmm lets see GMV, hmmmm, uh let me think a minute.

the 39 is a look back fault. the cpu checks the nts when leaving the floor. when you go in the direction of the open switch the elevator will travel a...

during a normal run the elevator stops electrically and then sets the brake, during an inspection run you just dump everything at ounce. on some contr...

the crosshead mounted encoder is the position encoder. the velocity encoder will be in the machine room, either mounted on the end of the motor, or dr...

never really worked on this type of controller but it sounds like you may have a relay hanging in with either residual magnetism or hanging in mechani...

the first thing I always did when having these kind of problems was to first replace the velocity encoder, making sure the counts and voltage on the n...

188 and 187 are, rope gripper failed to pick faults. could be a switch in the rope gripper itself or a bad k464.1 or k464.2 relay on the adon board, i...

you will register these particular faults every time you lose power, or every time you throw the main line switch. it indicates no voltage to the rec ...

I am not saying you should actually do this, but I once had a problem that was similar, I could not tell if the problem was mechanical or in the drive...

I agree with Philly, you need to isolate the problem. Is it directional? Is it mechanical? Have you gone through the parameters, you may have 1 or 2 o...

it may be worth putting a hand held tach on the drive sheave, make sure you are not going faster than contract speed in the up direction.

another way is to add an ice cube relay with the same coil voltage as the fire service light in the car. just parallel the coil with the fire service ...

is it possible that a corner of the brake lining is not picking off of the pulley, and then starts heating the pulley up as the day goes on, and at so...

the 39 is a look back fault. when you leave a terminal floor the computer looks back to see if all the rail switches have closed. If one is open you w...

had a similar problem once that turned out to be caused by one of the small white connector wires that are pushed on between two small metal pins on t...
