6 Red battery low warning led
A second red led is found next to the blue led (25) (see fig. 7).
When the red led, next to the blue one, turns on (the blue led stays on), this means that
the battery is low. About 10/15 minutes of autonomy remain at this point depending on the
temperature of use and battery wear conditions. At the end of this period, the HDV will
stop due to the cut-off device.
When the red led turns on, it remains on for as long as the switch is in the on position.
When the HDV is turned off, it may remain off the next time the HDV is turned on even if
the battery was not charged and turn on when the trigger is pressed. The battery low
indicator only works correctly when the HDV is running (propeller submerged and rotating).
Note: the sole purpose of the battery depleted signal is warn the diver that the
battery is low. HALCYON is not liable for the failed operation or erroneous
evaluation of residual battery charge which led to the incorrect assessment of HDV
autonomy.
The system is based on battery voltage readings that cannot fully guarantee
residual battery charge calculations. The indication highly depends on battery
wear.
7 HDV diving settings
The HDV should have NEUTRAL buoyancy and be practically horizontal meaning it
should not sink but remain stable at the desired depth. The vehicle is supplied neutrally
buoyant or slightly float in fresh water. Additional weights (23), are provided to compensate
for differences between use in fresh or salt water (see fig. 9) consisting in a stainless steel
ballast that should be included or removed according to whether the HDV is used in fresh
water (NOT USED) or seawater (USED).
