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 lim-
it
, 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 De-
lay
, par. 1-71 can be used in order to delay the motor start. The Bypass valve control principle:
The below setting options are all related to the Cascade Controller.
Wiring diagrams and settings for parameter, see group 25-** for more details.

Pump1 Running
One or more of the pumps controlled by the Cascade Controller are running. The function will also
depend on the setting of in

controlled by relay RELAY1 etc. If set to
Yes
[1] Pump 1 refers to the pump controlled by the
frequency converter only (without any of the build in relays involved) and Pump 2 to the pump
controlled by the relay RELAY1. See below table:
