Hi People
many thanks for the info... All sorted
LV contacts on the Levelling carriage not making and also dirty contacts on the ladder I think they are called hook switches.
If you punch the lift up or down using XU or XD, it will mask this problem as you are effectively bridging out the hook switches...
All down to poor maintenance ... an hour visit time for a controller like this is NOT enough.. what part of this do people like been counters not understand about this.
There are 8 of these lifts on site and all bar one are GREAT machines, now I have even got the homing and Duplexing to work correctly on this lift pair. Great.. all good

All the best and many thanks
