1)
The hysteresis is stated at rated and f = 0,02 Hz for a cycle. One cycle includes the movement from
neutral position to max. spool travel direction A, via neutral position to max. spool travel in direction B,
and back to neutral position. Further information can be obtained by contacting the Danfoss Power
Solutions Sales Organization.
2)
Reaction times for PVEH is reduced by 20 by 30 ms if the voltage is not interrupted during the neutral
positioning (remote control lever without neutral position switch).
3)
Total oil consumtion for a spool movement from N to full A or B: 0.0035 l [0.0009 US gal].
