™ OPERATIONAL
INSTRUCTIONS (v. 2.7)
DANGER!
The
diver at all times must be aware of the proper operation of the primary and
secondary systems. If the primary display at anytime fails to activate and
display the PO2, your solenoid will not activate due to the failure. Both the
primary and the secondary display systems are programmed to go to sleep
for power conservation after 10 minutes of inactivity (i.e. no switch hits)
during the dive until reawaked. Depressing the CONFIRM or MENU switch
awakens the subsystem and this inactivity timeout will restart. While the
displays are asleep, normal oxygen injection, sensor voting logic and all
other essential processing continues in the background.
APECS / SHEARWATER PURSUIT CONFIGURATION
APECS 2.5A hardware, in combination with APECS 2.7 software, permits
safe integration of third party decompression solutions. At present only
one product has met the stringent criteria and testing for integration with
the Megalodon and that is the Shearwater Pursuit Dive Computer.
Integration is achieved by replacing the secondary APECS 2.5 board with
an Isolation board. The secondary battery box powers the isolation board
The Shearwater is powered by it’s own internal battery. The APECS
primary board provides information to the APECS handset and controls
both the HUD and the solenoid on APECS heads, and the HUD on COPIS 2
heads.
The Teledyne R22D cells are connected to the APECS 2.5 board and the
Isolation board. A fault with either the Isolation board or the Shearwater
system or cable will not affect the APECS unit and vice versa.
Operational instructions and operating procedures and limitations as well
as software updates and support are available directly from Shearwater
Research Inc. (
www.rebreather.ca
). InnerSpace Systems strongly
recommends the hardwired configuration for maximum reliability but can
supply the APECS 2.5A hardware configuration with a Fischer cable to
accommodate divers who wish to be able to disconnect the Pursuit from
the head.
