I have a 2 bank schindler that is not acting as a group. Both units have their own hall calls and will respond to their hall calls respectively. Anybody have any pointers on how the interconnect for the group function works or could it be as easy as a setting in the controller I am missing?
I would try making sure that the interconnection between the ebcoms is consistent with the print, i've repaired a new install that had the signal wires swapped on the 5 pin connector from the factory. I like schindler prints, they are very informative on different functions. I recall that on a jamb installation the lon was in the lift bus and the group bus was used only when the customer splurged for the single centre button.
