If conditions allow you to remove the foreign body safely during the dive, then do so.
Otherwise let go of the HDV. Do not lubricate the safety device.
19 Electrical and mechanical safety systems applied to
the HDV R 14
In order to insure maximum diver safety when using the HDV, various solutions were
implemented to eliminate possible fault risks or potential injury.
19.1
Electronic engine control
The electronic engine control board includes:
A short circuit emergency fuse (on replaceable at authorized service centres)
Temperature sensor (slows propeller rotation to a stop. The system automatically restarts
when the engine is cool).
Maximum absorbed current sensor (maximum current that can be absorbed by the
electrical engine, fully automatic, to protect electronic parts)
Cut off (in addition to the one in the battery, even the electronic control automatically turns
off if powered with voltage under that prescribed).
Engine ignition sensor without mechanical contacts (the sensor is not a reed or
mechanical type but inductive)
19.2
Electronic battery control
The battery includes:
An emergency thermostat (if a battery charger fault occurs that overload the battery when
charging, the thermostat prevents battery overheating by cutting off the charge)
Cut off (in the event of depletion, it eliminates electric absorption cutting off the power
supply. It is restored when the battery is charged)
19.3
Switch
This HDV comes with a switch that cuts off the battery from the electronic engine control.
Using the switch limits accidental ignition which may not occur in any case if the switch is
in the OFF position.
19.4
Mechanical clutch on the propeller
See chapter 18.1
19.5
Trigger guard
The trigger is isolated by a guard that forces the diver to insert a finger in the ignition area
to press the trigger and start the HDV.
