Hint ee when new 60 seconds of running dry could be already too long for PowerSmoke 740 HV and damage the pump Do not fully empty the smoke oil tank during flight It is advantageous to start a stop watch when starting the pump and stopping the watch when stopping the pump this indicates on time when to stop the pump If for any reason hectic comes up powering the pump off could be easily forgotten In order to avoid unwanted powering on of the pump a main switch should be looped into the power supply e g EMCOTEC MPS If you do not want to use a switch disconnect the pump from the battery We point out that especially damages caused by running dry are not covered by warranty Page 20 of 27 PowerSmoke 740 HV Operating Instructions Version 1 0 The adjustment of the pump in respect to the transmitter signal can change over time This is especially caused by the running in of the pump and the motor The result could be that the flow rate changes over time in general somewhat increasing when the pump is not running full soeed You can correct this by changing the travel range easily Alternatively the pump can be newly taught in If not used for a longer time especially in winter time and when smoke oils with additives are in use corrosion can occur In general these are smoke oils with odorous substances e g smoke oils with strawberry or banana aroma These additives are often acidic and heavily hygroscopic

5. PowerSmoke 740 HV you purchased a high grade accessory for your model airplane PowerSmoke pumps are the most innovative and most high grade pumps with significant advantages over other systems on the market Best flow rate and optimal flow pressure at any time thanks to high precision metal toothed wheels highest manufacturing quality and electronics optimized into the ultimate detail and totally manufactured in Germany providing untroubled fun for an extraordinary hobby As with its predecessor the PowerSmoke 600 it is possible to connect an electrical back pressure valve which is controlled by the pump electronics We offer appropriate magnetically valves in our accessory program The PowerSmoke 740 HV HV stands for Head Valve integrates a back pressure valve This is unique in the fields of smoke pumps This back pressure valve makes the pump 100 leak proof and does not allow leaking for unwanted smoke oil to pass to benefit the environment and your model Please read these instructions carefully We do not assume liability for damages caused by ignoring the operating instructions as well as for damages caused by operating the PowerSmoke 740 HV The allowable usage of the PowerSmoke pumps is solely limited to smoke oil flow in unmanned airplanes Hint PowerSmoke pumps are not applicable for Bio Diesel Be careful with smoke oils including additives aroma add ons Please read chapter 8 Page 4 of 27 Powe

14. ing 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 Page 12 of 27 PowerSmoke 740 HV Operating Instructions Version 1 0 In order to unburden the receiver the supply can also be applied by a free channel of a battery switch with servo current distribution e g DPSI Mini DPSI RV or DPSI 2001 RV Here too observe the maximum possible current especially when the selected output voltage of the dual power supply is lower than the voltage of the connected battery It is saver to supply the pump with a separate battery The supply of the pump motor should contain a switch because even when the pump is inactive a small quiescent current 180A discharges the battery slowly Alternatively the battery can be simply disconnected Hint Do not use batteries for ignition systems or turbines as supply Hereby immense disturbances of the receiver set are possible Be aware that up to 6 amps of power on current can occur
