Helicopter mechanics with model turbine engine Smoker System The ECU can directly control a valve for blowing smoke fluid / diesel fuel into the exhaust efflux ( smoke generation). The smoker system is available as a kit, oder no. 6800.18. The function of the smoker valve can be adjusted in the Limits menu (parameter: “SmokerValve Ctrl”). LIMITS menu) are: Possible options for the “SmokerValve Ctrl” parameter ( Option Description DISABLED Smoker valve not used. The valve is always closed! Smoker valve is opened when the AUX switch (3-position switch) is moved to the back (“OFF”) position and when the turbine is running. Open if AuxSw=0 (*) Open if AuxSw=2 (*) If you wish to be able to use this function, the AUX switch must be active, i.e. the “AUX-channel func” parameter (see below) must not be set to “NOT USED”. Smoker valve is opened when the AUX switch (3-position switch) is moved to the forward (“ON”) position and when the turbine is running. If you wish to be able to use this function, the AUX switch must be active, i.e. the “AUX-channel func” parameter (see below) must not be set to “NOT USED”. (*) The function of the smoker valve can be tested when the turbine is not running: 1. 2. Set the rpm-slider to idle or OFF (otherwise there is danger that the fuel pump will start running during the subsequent test process!). For safety’s sake disconnect the fuel line to the turbine. Press and hold the "Manual" button (-> yellow LED flashes). The valve can now be operated using the AUX switch (3-position switch on transmitter). 58
