[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
) . 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.
