PowerSmoke 740 (HV) Operating Instructions
Version 2.0
Mount the clamps in a distance of 45mm at the desired position (e.g.
board inside of fuselage) with sheet metal screws 2.9x9.5 (delivered).
Additional cable ties or O-rings provide for additional support.
Remember, the pump remains always in the airplane and is exposed to
vibrations. The pump might be put into an appropriate foam insulation
hose (heating isolation material) which is glued into the fuselage or
fixed by cable ties. Damage caused by vibration is excluded from
warranty.
Hint:
Keep the pump clear from heavy vibrations because of its mass intensive parts
(pump). Damage by continuous vibrations can be encountered at electrical
connections or electronically parts.
4. Electrical Connection
All connectors are polarity proof using the Futaba coding. Of course,
JR connectors are appropriate, too.
The connector which is marked "RX" is provided a 3-pol patch cable
(control line) and then connected to the desired receiver output (or
output of a dual power supply, e.g. DPSI with servo current
distribution); a corresponding switch (servo channel) is to be selected
in the transmitter. No current flows practically to the receiver by this
patch cable.
The actual pump motor is separately supplied current by the connector
"BAT".
The connector "BAT" should be separated from the battery by a switch;
the quiescent current could discharge the battery otherwise.
Supply for the pump motor could be provided by a free receiver output
also. This saves an extra battery. Observe the current consumption of
the pump motor because the current loads the printed circuit board
tracks of the receiver.
