N-Vision Motor Controller AI-NV002-01-x Product Description The AI-NV002-01-x provides motor control for LCD monitor extending and retracting and is designed to specifically interface with the in-seat LCD 6.5” Monitor. The unit activates the ON/OFF controls of the video monitor mechanism. The “-x” suffix denotes the type of connector utilized in installation. Features The following list provides an overview of features for the AI-NV002-01-x: G G G G G G G G G Reverse voltage protection Delayed power reset Variable time shut-off during opening and closing Variable motor speed control Monitor supply switch output Video input BNC connector 5 second power interrupt protection Compact, lightweight Designed to meet aircraft standards 7. Application Notes 1. 2. 3. The AI-NV002-01-x is utilized in applications where motorized deployment of in-arm 6.5” LCD video monitors is required. A motor speed adjust screw (POT 1) is located on the rear of the unit. To increase the speed of the arm motor, turn the screw clockwise. To decrease the motor speed, turn the screw counterclockwise. A limit timeout adjust screw (POT 2) is located on the rear of the unit. To increase the amount of timeout, turn the screw clockwise. To decrease the amount of timeout, turn the screw counterclockwise. 8. The power for the LCD monitor is controlled via monitor input pin 1 and output pin 18. When the monitor is open, power is switched “on” via an internal relay to output pin 18. When the monitor is closed, the power is switched “off”. This ensures the monitor is not powered when the monitor is closed. Pins 13 and 14 are provided for an external kill switch that will disable the monitor system when applicable. Video signals from source equipment are sent to the controller via shielded, coaxial cable. The cable connects to the BNC connector on the back of the controller. The video signal passes directly to the monitor through the control module. Video output is provided on pins 15 through 17. Technical Specifications Electrical Power Installation Guidelines 1. 2. 3. 4. 5. 6. Mounting screws are required to secure the unit. Refer to outline drawing for mounting hole diameters and configurations. All video output lines shall be RG-179 coaxial cable or equivalent. All video input cable shall be twisted shielded cable with the shields properly grounded at the source. All power and ground wires shall be 22 AWG, minimum 20 AWG preferred. Power ground wires shall be grounded within twelve (12) inches of the unit. All wires shall be in accordance with MIL-W-22759 or equivalent. Twisted, shielded cable must be in accordance with MIL-W-27500 or equivalent. Protect power wires with circuit breakers or fuses located close to the electrical power source bus. The AI-NV002-01-x power input is protected against reverse voltage polarity and is filtered to produce a more stable supply. The limit switch provides internal relays to control inputs for external limit switches for minimum and maximum travel. Open S-1 is located on pins 5 and 6, close S-2 on pins 7 and 8. To provide protection against limit switch failures, an adjustable 2-15 second timing circuit is utilized; POT 1. This circuit controls the time delay that shuts off the motor and solenoid. When the time limit has expired, the motor and solenoid will disengage for added protection. Power reset controls the power up sequence for the controller. It ensures the controller will begin at a known state and serves as a safety feature. The LCD monitor will automatically close if the monitor is open and power has been removed for more than 5 seconds. Any power interruption less than 5 seconds will have no affect on the monitor. By interrupting power via the kill switch for more than 5 seconds, the monitor will automatically close if the trigger input is not active. Also, the control circuitry is designed to prevent power glitches from affecting the status of the LCD monitor.
