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.

Application Notes

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.

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.

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.
