Forward-Neutral-Reverse electric control (FNR), options: A9 (12 V) and B1 (24 V)
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 serviceable 125 μm screen is located in the supply line immediately before
the control porting spool.
