Connecting hose line for return quantity and
injection quantity
!
Pay attention to correct assignment of the measure-
ment channels when connecting the return quantity
and injected quantity hoses. A false assignment can
lead to wrong measurements and thus faulty assess-
ment of the injectors.
i
The following connection diagram for the EPS 708
(Fig. 83) or the EPS 815 (Fig. 84) is based on injec-
tor "A" by way of example. The connection of addi-
tional injectors (B, C, D, E and F) is identical.
