Forward-neutral-reverse (FNR) electic control
FNR principle
The 3-position FNR control uses an electric input signal to switch the pump to a full stroke position.
Under some circumstances, such as contamination, the control spool could stick and cause the pump to
stay at some displacement.
A 170 μm screen is located in the supply line immediately before the control porting spool.
