A Broken Belt condition has been detected. This function must be enabled in par. 22-60, Broken Belt Detection.
[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
Motor speed low limit
, par. 4 -11) . 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.
Start Delay
, par. 1-71 can be used in order to delay the motor start. The Bypass valve
control principle:
[196]
Fire Mode
The frequency converter is operating in Fire Mode. See 24-0*
Fire Mode
.
[197]
Fire Mode was act.
The frequency converter has been operating in Fire Mode, but is now back in normal operation.
