PowerSmoke 740 (HV) Operating Instructions
Version 2.0
Hint:
If the programming jumper is recognized being plugged in after finishing
programming the blue LED flashes 10 times per second until the programming
jumper is removed.
Hint:
If after removal of the programming jumper no valid servo signals are received,
programming is interrupted immediately without changing the configuration.
Hint:
Servo travel range between the off-position and the maximum flow rate must be
at least 30%.
The following servo travel ranges are allowed:
-100% to +100% (=200%)
-10% to +30% (= 40%)
Invalid range:
0% to +20% (= 20%)
Preprogrammed values at delivery:
1.1ms (-100%) start position (no flow rate – pump off)
1.9ms (+100%) end position (maximum flow rate)
Hint:
For safety reasons the pump turns on only above 10% of the start position and
then runs with a minimum flow rate of 20%.
An optimum flow rate is best assessed in flight based on the generated
amount of smoke. Adjustment is done e.g. via "servo travel" of the
transmitter. Experts could also program the flow rate depending on the
throttle position. The pump allows that thanks to it's electronically
regulation features.
