SYSTEM SYMBOL DESCRIPTIONS
Attention: Read Operating Manual for Warnings, Precautions,
and Instructions for Use.
Caution: Hot Surface
WARNINGS AND PRECAUTIONS
• The high intensity light at the front of the Light Source and the tip of the fiber
optic bundle will create high temperatures and bright light. To minimize the
risk of injury, avoid direct viewing or contact.
• To prevent temporary blinding and contact with heated parts, always plug the
fiber optic bundle into the Light Source before turning the power on.
• DO NOT switch the Light Source ON and OFF in rapid succession. Doing so will
dramatically shorten lamp life. After turning off, wait 10 to 15 seconds before
turning on again.
• CAUTION: PROVIDE ADEQUATE VENTILATION TO PREVENT OVERHEATING.
When using outside the carry pouch, do not drape the light source or place
the unit within 3 inches (7.62cm) of a solid object.
• USE CAUTION WHEN REPLACING LAMP. ALLOW LAMP TO COOL.
Use only Everest VIT replacement lamp #SPL-240.
• The supplied detachable power cord is the means of disconnect
from the power source.

TROUBLESHOOTING GUIDE

SYSTEM DESCRIPTION
The ELSV-24 Light Source provides high quality, white light for industrial borescope
and fiberscope inspections. It incorporates a patented and field-proven lamp
tech
nology
that has much greater efficiency than halogen or xenon lamps when
transferring light into a small fiber bundle, such as that found in borescopes and
fiberscopes. This greater efficiency allows the lamp to run at only 24W, which then
enables a small and lightweight light source design. You will also notice that the
ELSV-24 housing never gets very hot, so it is favored from a safety perspective as well.
For user convenience, the ELSV-24 is equipped with a video channel and multi-standard
light guide turret. The special video connector makes camera set-up and operation
easy by accepting the single power-video cable that is included with our BCAM
1000 c-mount borescope camera. This cable provides power to the camera and
car
ries the video signal from the camera back to the light source. The light
source
has a video output on the back which can then be connected to a
moni
tor or VCR
for image display and/or recording. The multi-standard light guide
turret
makes the
light source compatible with the four most common light guide fittings: ACMI, Wolf,
Olympus and Storz.

SYSTEM SET-UP AND OPERATION
CAUTION:
1. Verify that the supply voltage is within the 100-240VAC range specified
for this product.
2. To prevent temporary blinding, insert light guide into socket before
turning power ON.
3. The light guide tip and light source socket will be hot when light guide
is removed.
Set-up
1. With the power switch in the OFF position, plug the AC power cord into the
power input port on the back of the unit and then into a grounded receptacle.
2. Turn the Light Intensity Control Ring fully counter-clockwise to the minimum
position, rotate the light guide turret to select the compatible socket and plug
the light guide into the light socket.
Note: For proper lamp performance, make sure the light guide is fully inserted at all times.
3. Turn the power switch ON (position I). The lamp will take 10 - 15 seconds to
complete the warm-up cycle. [If the power has just been turned off, allow 15
seconds before turning ON again.]
4. Set the light intensity to the desired level by turning the Light Intensity
Control Ring.
Note: Do not restart the Light Source immediately after shutting it off - it may fail to light. If this
occurs, turn the power off and wait 10 -15 seconds before turning the unit back on.

USER MAINTENANCE (contd.)
CLEANING
WARNING: Prior to cleaning, turn power switch OFF and disconnect the
power cord from both the wall outlet and light source.
Clean the external surfaces of the light source with a cloth dampened in a solution
of mild soap and water. DO NOT IMMERSE!
The power cord may be wiped cleaned in the same way, taking care not to get the
prongs wet. DO NOT RECONNECT POWER CORD WHILE WET!
DO NOT plug the ELSV-24 light source into a wall outlet until it and the power cord
are completely dry.
The ELSV-24 is a fairly maintenance-free product. Should a problem occur that is
not fixed by replacement of the lamp or fuse, call the Everest VIT Service Center listed
in the back of this manual. THERE ARE NO USER SERVICEABLE COMPONENTS IN
THIS PRODUCT, OTHER THAN LAMP AND FUSE SETS.
p.7
USER MAINTENANCE (contd.)
FUSE REPLACEMENT
1. Turn the unit off and disconnect the power cord from both the wall outlet and the
light source.
2.
Locate the fuse drawer, which is positioned just above the power cord connector
on the
back panel. Unlock the drawer by using a small screwdriver (1/8") to
depress and
release the spring loaded snap connection. Pull out the fuse drawer.
3.
Remove and replace fuses with new fuses of the same type (see Specifications)
. There is
no special orientation of the fuses. Be sure to replace both fuses.
4. Reinsert the fuse drawer by pushing it into the drawer socket until it snaps into place.
Note: If the new fuse blows, contact the service center listed in the back of this manual.

SYSTEM SET-UP AND OPERATION (contd.)
ON/OFF Switch
A two position rocker switch is used to turn the unit on or off. Depressing the side
marked with a " I " turns the unit on, while depressing the side marked with an "O"
turns it off.
Light Intensity Control Ring
The outer ring around the light guide socket rotates to adjust the amount of light
transferred into the light guide. Rotating the ring clockwise will increase the
amount of light in the image and rotating the ring counter clockwise will decrease
the amount of light. This manual control is helpful when trying to better illuminate
one part of the image or when trying to reduce blooming.
Light Guide Turret
The light guide turret enables the light source to accept different light guide fittings
without additional adapters. Simply rotate the turret to position the desired light
guide port in front of the lamp (6:00 position). The most common fitting, and the one
used most predominantly by Everest VIT, is the standard ACMI port. Other fittings
provided are Wolf, Olympus and Storz.
Carry and Operation Pouch (optional)
A custom designed soft carry pouch with shoulder strap is available as an accessory
.
The pouch carries the light source on one side with space on the opposite side for
accessories such as light guides, spare lamps, video cables, etc. Specially designed
access ports and vents allow the light source to be operated while inside the pouch.

SYSTEM SET-UP AND OPERATION (contd.)
For Use With BCAM 1000 C-mount Video Camera
Video Connector
The video connector is used when the Everest VIT BCAM 1000 c-mount camera is
being used with the rigid borescope or fiberscope. The BCAM camera cable connects directly to this light source connector to provide simplified, one-cable hookup.
This customized cable provides power to the camera from the light source, and
relays the camera video to the light source, where is can be accessed through the
S-video and/or composite video output connectors on the back panel.
Video Outputs
S-video and composite BNC connectors are provided on the back panel of the light
source. When the light source is connected to the BCAM c-mount camera, the
camera video can be displayed and/or recorded by connecting a video cable from
one of these video outputs to a monitor and/or VCR.

USER MAINTENANCE
LAMP REPLACEMENT
CAUTION: Lamp may be Hot! Allow the lamp to cool before replacing.
Note: Use only Everest VIT replacement lamp SPL240.
DO NOT touch the lamp itself or the interior reflective surface, because skin oils will
cause premature lamp failure. If necessary, clean fingerprints with an alcohol
dampened cotton swab. Do not leave lint on the lamp.
1. Turn the unit off and disconnect the power cord from both the wall outlet and the light
source.
2. Remove the lamp access door from the bottom of the unit by unscrewing the Lamp
Access Knob located on the lower back panel.
3. Remove the old lamp by disconnecting the wire harness connector from the lamp and
then pulling the lamp back against the retainer spring and up. Discard the old lamp.
4. Holding the new lamp by its housing, connect the new lamp to the wire harness
connector and install by pulling back on the retainer spring, aligning the pin on the
lamp with the notch in the housing, and allowing the spring to push the lamp forward
into position.
5. Reattach the lamp access door and tighten the Lamp Access Knob. The light source will
not turn on unless the Lamp access door is secure.
