[195] Bypass Valve Control The bypass valve control (Digital / Relay output in the frequency converter) 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 [RPM]
) . After the limit has been reached the bypass valve will be closed, allowing the
compressor to operate normally. 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.
