Functions. Signal selection for pressure regulator

Pressure regulated motors shift to maximum displacement at high operating pressure, irrespective of which side is under pressure.
In propel drives this can have undesirable effects. For example, if the motor shifts to maximum displacement during the transition
phase from straight travel with low system pressure to overrun (deceleration, downhill travel) with high pressure on the reverse
side, an extremely strong vehicle braking effect will occur. The signal selection for pressure regulator prevents the regulator being
subjected to this braking pressure and, therefore, ensures that the motor remains at minimum displacement. For equipment options
for Series 02 motors please refer to the model code.
