Controller Power Supply
1. Camera control on the Controller Power Supply
The adjustable camera power supply provides a nominal 120V DC to the camera, transporter
and other down-hole inspection equipment. This section has video processing circuitry which
extracts the video transmitted by the under ground camera into a NTSC video format. Also
incorporated in to the controller is an audio microphone preamplifier, which provides audio for a
VCR.
The Camera ON/OFF switch controls the camera power supply. Above the switch is a green
LED to indicate that the camera power supply is
on
.
The Camera POWER control knob adjusts the output Voltage of the power supply. Zoom
cameras have a non-adjustable light source. The Camera power only adjusts speed of the
transporter unit. Increase Camera
power
control knob until a red bar appears on the screen.
Decrease Camera
power
knob until red bar just leaves the screen. The transporter speed will
not increase after red bar limit appears on the screen.
Caution:
Do not operate equipment with the over limit red bar on screen.
