Hi, I've a hydraulic unit with two accumulators and there are normal values for accumulator pressures (p0, p1 and p2) in schematic, but there are also p3 and p4.
What do the p3 and p4 stand for?
p0 = 90 bar
p1 = 110 bar
p2 = 160 bar
p3 = 170 bar
p4 = 210 bar
Pressure relief valve is set to 250 bar.
It might have something to do with electric pressure transmitter controlling the two gear pumps on and off, but I have no information on the controlling pressures.
