The JMP Gear/Door Sequencer has four timed control options available. These options are illustrated below. The servo that activates the door control valve is plugged into the top position with the black or brown negative wire to the inside. The servo that activates the retract gear control valve is plugged into the lower position with the black or brown negative wire to the inside Servo throw travel volume is preset to match most available control valves. The green LED on the top of the case indicates that the sequencer is active. Contained in the sequencer computer code is a Gear Up Fail Safe. If the model receiver is turned on with the transmitter retract gear switch in the up position, both gear and door control servos will hold in the down position. Gear and door control servos will become active when the transmitter retract gear switch is returned to the down position. This fail safe feature will prevent accidental retraction of the gear on the ground. An easy way to understand this function is that the sequencer must see a down switch before it can respond to an up switch. .
