CONNECTING WITH THE EC-2
Connect the receiver and servo-related components (rudder section) in the same manner as in the past.
(5) RPM sensor input terminal
(r.p.m.)
(1) Injection time input terminal
(CH3:THRO)
Two extension cords (sold separately) of a length corresponding to the airframe are required for
connecting (1) and (2).
(1) Injection Time Input Terminal<Black> (CH3:THRO)
Connect the y harness provided with the CH3 THRO input terminal to throttle channel of the
receiver (throttle: CH3), connect the wiring connector from the throttle servo to one of the double-
opening connectors on the opposite side, and connect the other double-opening connector to
CH3:THRO of EC-2. (Use the separately sold extension cord if the wiring cords are too short.)
(2) Injection Trim Input Terminal<Red> (AUX:TRIM)
Connect a spare channel for dial use of the receiver (e.g. channel 7) to the AUX:TRIM terminal.
(Use the separately sold extension cord if the wiring cords
are too short.)
(3) Injector Output Terminal
Connect the injector connector to the injector output terminal. Protect the lead wire with a heat-
resistant tube,etc. if it makes contact with the engine mount.
(4) Temperature Sensor Input Terminal
Connect the temperature sensor connector to the temperature sensor input terminal.
(5) Rotation Sensor Input Terminal Connect the rotation sensor connector to the rpm input terminal.
(2) Injection trim input terminal
(AUX:TRIM)
(3) Injector output terminal
(INJECTOR)
(4) Temperature sensor input
terminal (Temp)
(8) Integrated Buzzer
(6) Limit Setting Switch(LIMIT) (7) L.E.D.
