A No-Flow situation or Minimum Speed situation has been detected if
enabled in par.22-22 Low Speed
A Dry Pump condition has been detected.

The bypass valve control (Digital / Relay output in the frequency con-
verter) is used for compressor systems to unload the compressor during
start-up by using a bypass valve. After the start command is given the
bypass valve will be open until the frequency converter reaches par.
4-11 Motor Speed Low Limit
bypass valve will be closed, allowing the compressor to operate nor-
mally. This procedure will not be activated again before a new start is
initiated and the frequency converter speed is zero during the receiving
of start signal. par.1-71 Start Delay
