Highleg
With all wires in place
does not respond to hall or car call
Door operator has no power
If ina is removed from terminal car runs up (nothin is jumping ins to u)
If u is removed from terminal
Door operator works
car levels into floor
Car will not run only pump will run valve wont pic
Eevator seems to be stuck on inspection and up if u is on terminal from the selinoid of lu
Pulled all cards car runs up with no cards in
Swaped all cards
Checked 25v across 24d pc blue cap
Replaced rect board with diodes
This happend after a seal was done the only mistake was wrong jumper to run up from a high voltage valve terminal to u which blew the 6 amp fuse # 4
Have isolated high leg by removing #10 fuse problem still happens
??????????
Any ideas
Unfortunately, I haven't had any experience on one of these.
The only thing I can think of is either a popped capacitor or a short in the safety string; I've seen that a lot on older Dovers. Are you certain fuse #4 is 6A rated - that runs off the transformer, correct?
Also check pc to 24d - should be about 25vdc; if not you could add a capacitor rated 250vdc 250uf.
and check 9vdc to sc which should be about 15vdc; if not then you more than likely have a bad power card.
Hope this helps.
^ im goin to replace caps tm
Thank you both im open to all help im really stuck
Maybe 40 years is enough and time to replace control.
Everything seems to operate normal now
Runs up and down on insp as needed doors work good
Will hold calls but only runs pump not picking the valve
??
Diode zener board blwon
Wiring from last contractor had limit switch jumped for repair had to put it back
They replaced f1 and took wire off v21 so jumper from v21 to p8 is needed to run now ???
