CAUTION
The Eclipse system can only work with a SeQual Power Cartridge. Use of
another Power Cartridge or Battery may damage the unit, present a risk of fire
or explosion and will void the warranty.
The capacity of the Eclipse Power Cartridge is determined by electronics and the Eclipse software.
Figure 8: Power Cartridge Status Gauge
While the Eclipse Power Cartridge allows the concentrator to operate at its full range of capabilities, the
primary purpose of the Power Cartridge is to allow a patient to ambulate while they are moving between
stationary power sources. The Eclipse’s Power Cartridge, like all lithium ion batteries, is susceptible to
permanent damage from excessive heat. Exposure to excessive heat may shorten the Power
Cartridge’s service life significantly.
Each Power Cartridge contains multiple temperature sensors to monitor battery cell temperature. The
amount of heat the Power Cartridge can safely endure varies depending on how the Power Cartridge is
being used. During discharge, the Eclipse software will alarm when internal battery cell temperature
exceeds 60°C, and will shut the system down if internal battery cell temperature exceeds 70°C. While
the Power Cartridge is charging, software will interrupt charger operation when the internal battery
temperature exceeds 45°C or temperature is less than 0°C . In both of these cases, when internal
battery cell temperature falls below these limits, the Eclipse will resume normal operation. Operation
near these temperature limits will not damage the Power Cartridge, but are in place to ensure that the
service life of the Power Cartridge is preserved.
Heat in the Power Cartridge is generated during discharge, and can also be the result of operating the
Eclipse in high ambient temperatures. The amount of internally generated heat varies with the flow
setting – higher flows induce greater Power Cartridge heating. While high ambient temperatures are
typically the result of operation on a hot day, running the Eclipse with inadequate ventilation can also
induce them. Always ensure that the Eclipse is operated in a well-ventilated space, the air intake filter is
clean, and intake and exhaust vents are unobstructed.
Charging Algorithm
The charging algorithm is performed by the Power Manager software and must make three basic
decisions:
1. When to start charging
2. How fast to charge
3. When to stop charging
