Hie guys can someone assist lm resuscitating a lift water damaged at a water treatment plant I'm having the following problems on my motion 4000 controller when l try to run it in automatic mode -:
1.GS input failure.....but if you check on the inputs the led displays it's input as high on HC-CTL control booard
2.MPI-A relative position low when on bottom floor and MPI-A relative position high on top floor
Have relaced the MC -LSI landing system interface

MPI-A,
Have you tried the board reset?
Have you tried the board reset?
GS,
Is DPM picking prior?
Is DLAB picked while GS is picked?

You will get the GS input failure if the controller sees the gate switch made up when you don't have a door lock or the DPM input. The controller thinks the gate switch is jumped and won't let you run. You should look at the door operator. What kind of door operator do you have?
As far as MPI-A relative position high or low, you probably need a new ELGO tape reader head, sounds like channel A is not communicating. Flip dip switch F3 up go to controller system menu then "N" until you see ELGO A and B info. If channel A has all zeroes, and channel B has numbers (position info), you have a bad tape reader head. You can swap the shielded pairs on the TC-MPI board in the controller and then see if channel B has all zeroes, and if channel A has the data to confirm.
