Ingersoll Rand X8I Mode D'emploi page 36

• If air system storage is generous and the rate of the
pressure change is slow to rise, then the 'Damping'
can be increased to improve pressure control
without compromise to optimum energy efficiency.
As the Dampening value is increased, the Loading of
additional compressors is less rapid.
• If air system storage is inadequate and the rate of
the pressure change is fast to fall, then the 'Damping'
can be decreased to improve pressure control
without compromise to optimum energy efficiency.
As the Damping value is decreased, the Loading of
additional compressors is more rapid.
Damping also performs one more important function
that can arise in a system. When the system pressure
achieves stability in a position that may be outside of
the dead band but inside the tolerance band it will
be allowed to remain in this situation for a predefined
amount of time. This time limit depends on how far away
from the dead band the system pressure has stabilized.
This time limit is calculated as 30 min times the damping
constant at the top of the tolerance band and as 1
min times the damping constant at the bottom of the
tolerance band.
S02 - PC Pressure Change Time
This parameter adjusts the time that the X8I will
implement a smooth and controlled change from one
'target' pressure level to another when a table change is
made. The default setting for this parameter is 4 Min. The
values for this parameter are:
"1", 1 minute between Table target pressure setpoint
changes
TO
"120", 120 minutes between Table target pressure
setpoint changes.
S02 – CA Capacity Alarm Enable
This parameter sets the functionality of the Capacity
Alarm. The default setting for this parameter is
(Represents the Capacity Alarm is enabled) The values for
this parameter are:
= inhibit Capacity Alarm
= enable Capacity Alarm
When inhibited the Capacity Alarm panel indication
will still function; alarm code generation and remote
alarm indications are inhibited.
S02 – MA Restricted Cap. Alarm Enable
This parameter sets the functionality of the Restricted
Capacity Alarm. The default setting for this parameter is
. (Represents the Restricted Capacity Alarm is enabled)
The values for this parameter are:
= inhibit Restricted Capacity Alarm
= enable Restricted Capacity Alarm
When inhibited the Restricted Capacity Alarm panel
indication will still function; alarm code generation and
remote alarm indications are inhibited.
