RMS (Resources Management System)
The control of PO
2
is the prime function for EXPLORER. In addition it
monitors a range of dive resources. The LSS is able to make advanced
decisions based on available resources in order to modify the PO
2
and
provide for the longest possible dive.
The unit constantly monitors all resources such as available gas, scrub-
ber duration, etc. and keeps the dive within parameters that allows for a
safe bailout ascent. The unit uses a forward-looking algorithm to deter-
mine the best PO
2
at any given time to avoid or reduce decompression,
allow for a safe open circuit ascent and stay within safe battery and
scrubber durations.
Resources monitored include;
• Depth
• NDL
• PO
2
• PCO
2
• Battery
• HP gas
• CNS (Oxygen toxicity)
• Filter (CO
2
scrubber)
Resources are generally expressed in minutes and are noted in the cen-
ter of the dive screen (Fig. 3.20).
The controlling (most critical) resource is shown. This can change
throughout the dive and another resource may take its place. Alarms will
be activated when resources reach certain levels as defined in the Alarm
Tables.
In addition, should a resource alarm be triggered for any reason the STA-
TUS screen will appear. This will not only note the resource level but can
also tell the user of the direct action required, i.e. ASCEND NOW.
