Page 4: General
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 –... -

The PowerSmoke 740 HV can be powered by 3S LiPo batteries because this pump has a wider suction hose connector. The PowerSmoke 740 can only be supplied by up to 2S LiPo batteries. At higher voltages this pump tends to cavitate. - Page 6 PowerSmoke 740 (HV) Operating Instructions Version 2.0 PowerSmoke 740 PowerSmoke 740 HV Picture shows PowerSmoke 740 HV with mounting brackets.

Page 7: Specifications
PowerSmoke 740 (HV) Operating Instructions Version 2.0 2. Specifications 2.1. PowerSmoke 740 Dimensions: 61mm x 27mm (Length x Diameter) Quiescent Current: approx. 30mA (with powered receiver set) Weight: Max. Flow Pressure: approx. 5.5 bar Table1 - maximum suction hose length for inner diameter 2.5mm / 4.0mm is dependent on amount of flow rate. -
Page 8: Powersmoke 740 Hv (Headvalve)
Table1 - maximum suction hose length for inner diameter 4.0mm is dependent on amount of flow rate. A suction hose with 2.5mm inner diameter cannot be used with the PowerSmoke 740 HV due to their bigger suction connector. Hose ID... -
Page 9: Mounting
3. Mounting It is advantageous to mount the pump higher than the tank. This is especially true for the PowerSmoke 740 if not using the check valve. When using a magnetically valve or the check valve, the mounting position does not matter. - Page 10 PowerSmoke 740 (HV) Operating Instructions Version 2.0 The PowerSmoke 740 HV has an integrated valve and can therefore be even positioned lower than the tank. Flow direction is marked by an arrow. The "R" marked connector (swing fixture) is to be routed back to the tank. Back flow is approx.
- Page 11 PowerSmoke 740 (HV) Operating Instructions Version 2.0 Never fill the smoke oil tank via the suction hose in order to avoid contamination of the pump. Length of the pressurized hose is not critical and may be up to 1.5 meters.

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. - Page 13 PowerSmoke 740 (HV) Operating Instructions Version 2.0 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...

Page 14: Connecting To Tanking System
Hint: Flow direction is not reversible by electronics! On the suction hose side of the PowerSmoke 740 a hose with an inner diameter of 2.5mm can be used. We recommend for all pumps a suction hose with 3.5mm or 4mm inner diameter (simply connectable by adaptor instead –... -
Page 15: Connecting To Exhaust System
PowerSmoke 740 (HV) Operating Instructions Version 2.0 Our connection set includes all parts in order to allow for optimal flow rates. On the pressure side we recommend 2.5mm plastic hoses (PUN) or Tygon hoses, at least near the exhaust system. We recommend changing from the plastic or Tygon hose to a heat resistant Viton hose (close to the muffler) at late as possible (see chapter 6). - Page 16 An additional support is in order for longer pipes which must be mounted to the same part as the pipe itself; this means, do not mount the support to the fuselage if the pipe is soldered to the manifold.

Page 17: Initial Operation / Teach-In Of Pump
PowerSmoke 740 (HV) Operating Instructions Version 2.0 7. Initial Operation / Teach-in of Pump Hint: After mounting and finishing connections it is advisable to test and possibly program (teach in) the smoke oil pump. Generally, after mounting any electrical add-on device, a range test with powered pump should be conducted. - Page 18 After power on, the blue LED of the PowerSmoke 740 (HV) is lit permanently. This indicates activated programming. First setup minimum servo position where the pump should not run.
- Page 19 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.

Page 20: Hints For Daily Operation
Hint: Especially when new 60 seconds of running dry could be already too long for the 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);... - Page 21 PowerSmoke 740 (HV) Operating Instructions Version 2.0 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 speed.

Page 22: Using A Back Pressure Valve
Therefore we recommend usage of the PowerSmoke 740 HV with integrated back pressure valve or an additional check valve in the pressure line of the PowerSmoke 740. - Page 23 PowerSmoke 740 (HV) Operating Instructions Version 2.0 Examples based on PowerSmoke 600 Page 23 of 27...

Page 24: Magnetically Valve
9.2. Magnetically Valve A very comfortable possibility is to loop in a magnetically valve into the pressure line. The pump electronics of the PowerSmoke 740 (HV) allows for such a valve to be connected and controlled. Theoretically any magnetically valve with 5 volts and a maximum of 300mA current can be connected. -
