* Pressure Override Only
The pressure override and pressure limiter accomplish the
same function - they shift the pump swashplate toward neutral
when system pressure exceeds a preset threshold. They thus
limit maximum system pressure, protect components from heat
power. Pressure override is available only for Series 2X pumps,
and pressure limiting is available only for 3X pumps. Pressure
limiting and annular control are not available together. If the
model code chosen indicates that pressure override function is
ration parameter, above). The pressure override valve must be
obtained through Sauer-Danfoss, Ames, IA. The pressure limiting
feature is inherent in the design of the MCV104 when applied
with the 3X pump.

It may be preferred to apply the dual coil versus the single coil
EDC. The dual coil allows two command sources to be combined
at the torque motor, the resulting signal being the
tween the two. Dual coil models can be connected in parallel or

above are necessary for installation and they are not included
in the kit.
Several Sauer-Danfoss variable pumps come without pre-
mounted controls. These pumps will need additional mounting
hardware that generally accompanies the control in order to
accomodate the EDC. The pump numbers are: 34-2035, 34-2060,
34-2080, 36-2047, 36-2056, 36-2081, 36-2082.
If you wish to mount an EDC on one of these pumps, order a
K07015 (9004700-1212) roll pin, a 9004875-0020 straight pin
and a 9340301 (for Series 34 pumps) or 9360354 (for Series 36
pumps) drag link.
