Action
(Priority on probe failure
alarms)
The % of the valve updates
every second in order to reach
the correct percentage.
If the receiver pressure value
is between the values GC29
and GC28 – 1 (bar), the % of
valve opening is as follows:
(Priority on probe failure
alarms)
The HPV will close (0 %).
The BGV will open to a user-
defined % set by parameter
GC37.
The HPV will have a minimum
opening to a user-defined %
set by GC36.
If the PID % is greater than
GC36, then the PID % will be
the valve % output.
The BGV will close.
Only signalling
Reset
Automatically as soon as the HP REC
is active or as soon as AIC98 (AIC99) <
GC29 – GC30
Automatically as soon as AIC98
(AIC99) < GC28 – GC30
Automatically as soon as AIC98
(AIC99) > GC31 + GC32
The communication is recovered
