This unit has gone into low oil twice in the last 2 weeks, stops mid flight with pump running, then eventually times out. After the last reset it wont run up on auto or inspection. U1 energises but UD and TU don't energise. don't see anywhere on the print this is done. Looks like its done on the board. The outputs for UD and TU don't turn on when U1 goes high. Looking for any assistance or technical manual. the manual I have does not expand on this sequence of operations.

Outputs o46 and o 49 energize TU and UD it’s done from opto couplers on the board. Try changing chip on board
