EMERGENCY behaviour
The emergency behaviour of the by-pass function has the same characteristics as
the <EMERGENCY behaviour> function with the following differences:
In an EMERGENCY situation, both controls receive the EMERGENCY signal at the
same time.This signal starts the EMERGENCY operation specially defined for the
by-pass function. (Parameter EMCY operation M0204 is therefore not available in
the <EMERGENCY behaviour> function).
EMERGENCY operation procedure
1. By-pass valve is opened first.
2. Once the by-pass valve is fully opened, the main valve is closed.
3. Once the main valve is fully closed, the by-pass valve is fully opened.
