Pressure Schedule
P01 – 01 to 28
The 'Pressure Schedule' items 01 to 28. The Pressure
Schedule consists of 28 individual settings that instruct
the X8I to change from one Table to another, or put
the system into Standby mode, dependant on time of
day and day of the week. The default setting for this
parameter is -. --:-- - - - . (Represents the Pressure Schedule
is disabled)
The values for this parameter are: (from left to right)
Day of the Week. The values for this parameter are:
"1" for Monday to "7" for Sunday (a specific day
of the week)
"8" for every working day of the week (every
day, Monday through Friday, excluding
Saturday and Sunday)
"9'" for every working day of the week (every
day, Monday through Sunday)
"–" represents the Pressure Schedule is
disabled.
Hours (Military Time). The values for this parameter
are:
"00" to "23" the hours in a day
"–-" represents the Pressure Schedule is
disabled.
Minutes. The values for this parameter are:
"0" to "59". the minutes in the hour
"__" represents the Pressure Schedule is
disabled.
Table / Standby mode selection. This instructs the system
to change from one 'Table' to another, or put the system
in to 'Standby' mode for the Pressure Schedule. The values
for this parameter are:
"T01", "T02", "T03" or "T04" for the 4 different

Prefill
P02 - PF Prefill Function
Determines the 'Prefill' strategy or function that will
be used at system startup. The default setting for this
parameter is A .
A
(Represents the pre-fill function is in Automatic
Mode)
The values for this parameter are:
= Prefill function OFF
" " = Prefill, Back-up Mode
Compressor(s) can be pre-selected as 'Primary
Pre-fill' compressor(s) or 'Backup Pre-fill'
compressor(s). If a primary pre-fill compressor
experiences a shutdown, or is stopped, it is
replaced by a pre-defined backup compressor
and pre-fill continues.
= Prefill, Standard Mode
If one or more of the pre-defined pre-fill
compressors experiences a shutdown, or is
stopped, the pre-fill function is cancelled and
normal operation begins.
A
= Prefill, Automatic Mode
No Prefill compressor selection is necessary;
any selection set is ignored. The management
unit automatically selects compressor(s)
dynamically to achieve pressure in accordance
with the set Prefill time. If a compressor is
stopped, or shuts down, it is automatically
substituted with an alternative compressor.
P02 - PT Prefill Time
The Pre-fill Time Setpoint (in minutes) sets the maximum
time allowed for a system to start and load the
designated Compressor/s to increase system pressure
to normal operational levels. The default setting for this
parameter is – . (Represents the Prefill is disabled)
The values for this parameter are:
"–" the Pre-fill Time is Off
"1 to 120" the number of minutes
