Tables
# = Table T01 to T04
T0# – PH High Pressure Set Point
The 'upper' or 'unload' pressure set point that will be
used when the 'Table' is active. The default setting for this
parameter is 102 PSI. The values for this parameter are:
The highest value for the High Pressure setpoint = PM
"Maximum Pressure Alarm" minus 2 times TO "Tolerance".
If PM is set for 145 PSI and TO is set for 3.0 PSI, then the
highest value for the High Pressure setpoint would be 139
PSI.
The lowest value for the High Pressure setpoint = PL "Low
Pressure" setpoint plus TO "Tolerance"
If PL is set for 98 PSI and TO is set for 3.0 PSI, then the
lowest value for the High Pressure setpoint would be 101
PSI.
T0# - PL Low Pressure Set Point
The 'lower' or 'load' pressure set point that will be used
when the 'Table' is active. The default setting for this
parameter is 98 PSI. The values for this parameter are:
The highest value for the Low Pressure setpoint = PH
"High Pressure" setpoint minus TO "Tolerance".
If PH is set for 102 PSI and TO is set for 3.0 PSI, then the
highest value for the Low Pressure setpoint would be 99
PSI.
The lowest value for the Low Pressure setpoint = Pm
"Minimum Pressure Alarm" setpoint plus 2 times TO
"Tolerance"
If Pm is set for 80 PSI and TO is set for 3.0 PSI, then the
lowest value for the Low Pressure setpoint would be 86
PSI...
T0# - Pm Minimum Pressure Alarm
The miniumum pressure 'Warning' or 'Alarm' level that will
be used when the 'Table' is active. The default setting for
this parameter is 80 PSI. The values for this parameter are:
The lowest Minimum Pressure Alarm setpoint = "The
minimum range of the pressure transducer used."
The highest Minimum Pressure Alarm setpoint = "The
value from the Table PL – Low Pressure Setpoint" minus 2
times TO "Tolerance""

If PL in Table 1 (T01) is set for 100 PSI and TO is set for 3.0
PSI, then the highest Minimum Pressure setpoint would
be 94 PSI.
T0# - SQ Sequence Strategy
The sequence control strategy mode that will be used
when the table is active. The default setting for this
parameter is ENER.
The values for this parameter are:
ENER – Energy Control Mode. The Rotation and
Control functionality of the ENER mode is to achieve
and maintain demand matched to optimum system
efficiency.
FILO – First In Last Out. The Rotation and Control
functionality of the FILO mode is the first compressor
loaded is the last compressor to be unloaded
EHR – Equal Hours Mode. The Rotation and Control
functionality of the EHR mode is to equalize the Run
Hours on all compressors
T0# - 01 Compressor #1 Priority
The 'priority' setting for compressor number 1 that will be
used when the table is active.
T0# - 02 Compressor #2 Priority
The 'priority' setting for compressor number 2 that will be
used when the table is active.
T0# - 'n' Compressor #'n' Priority
The 'priority' setting for compressor number 'n' that will be
used when the table is active.
'n' = number of compressors in the system. 8 is the
maximum number of compressors for the X8I
Priority Settings:
: compressor(s) can be inhibited from use while a
table is active by selecting "X" priority. The compressor
will be held offload and will not be utilised under any
circumstances.
