Page 2: Set Components
After starting of the engine and reaching of required rpm (in the automatic mode green LED blinks) LPG supply is switched on (green LED shines constantly). The LPG output is controlled with a actuator and depends on lambda sensor indications. All STAG-50/100/150 parameters are set with an external tester or a PC (AcLpgWin software). - Page 3 WIRING DIAGRAM AND INSTALLATION MANUAL The STAG-50/100/150 controller should be mounted within the engine room in the place, which is not exposed to high temperature, water and fuel. CAUTION! It is recommended to install the controller vertically using its mounting eye and a screw, placing sockets downward to avoid water penetration.
