Under normal conditions of use,

the DVS-V will require little

maintenance if it is protected by

a dust cover when not in use.

Virtually no repair or adjustment

will be needed, since all operat-

ing component are protected and

solid-state circuitry assures ex-

ceptionally high reliability.

Cleaning

Periodically, some cleaning will

be necessary. The main instru-

ment housing and control unit

should be dusted from time to

time with a soft cloth or brush …

and the lenses washed with soap

and water and dried with a soft

cloth or tissue.

If the instrument has become

very soiled, it may be washed

with a mild soap and water solu-

tion or wiped with a general pur-

pose spray cleaner. (Other sol-

vents are not recommended.)

Be sure to disconnect the unit

from its power supply before

washing.

When the DVS-V is used in a

heavy industrial environment,

such as that of a foundry, it is

possible that some dust may ac-

cumulate on the stereo targets.

In this case, remove the top

cover of the instrument and care-

fully dust the targets with a soft

camel’s hair brush. The drum

should not be removed. Instead,

rotate it using the test advance /

reverse buttons on the control

panel.

If carrying the instrument long

distances, Keystone View rec-

ommends transporting it in its

specially-designed carrying case.

Lamp Replacement

Two Nichia NSPW515BS Long-

Life Daylight LED’s lamps pro-

vide illumination of the stereo

targets. Although they are rated

for a long duration of continuous

use, replacement may eventually

be required. Two extra lamps

are included with the DVS-V,

they are taped on the inside wall

of the machine. Simply unscrew

and remove the top panel in or-

der to access the lamps.

Fuse Replacement

A standard 3/4 ampere automo-

tive-type fuse is incorporated in

the circuitry of the DVS-V to

protect the unit against possible

electrical malfunction.

Should replacement ever be re-

quired, order an 3 AG 3/4 amp.

Fuse (1,25 inches long) from

your distributor (Part No. 297-

800).

Target Drum Installation and

Synchronization

The DVS-V Screener is shipped

ready for operation, with the tar-

get drum installed and synchro-

nized with the control panel.

Should the drum need to be re-

placed or removed, instrument

owners can reinstall the drum

using the following guidelines:

Drum Removal: Push the spring

clips outward from the end of the

drum. Slide the drum towards

the rear of the instrument (away

from the gears) and lift it out.

Drum Replacement and Syn-

chronization:

1) Turn power switch on.

Slowly rotate the black position

gear until the motor gear stops

moving. Observe which signal

light on the control panel is lit.

This shows how the drum is to

be installed.

2) To synchronize the target

drum with the control, the drum

must be inserted with the corre-

sponding target facing the lens

openings at the front.

Insert the drum downward be-

tween the spring clips. Slide it

forward toward the lenses until

the clips snap in toward the

drum. The drum gear cogs

should now be engaged with the

gears on both sides.

3) Press the test advance button

on the control to move the drum

to the next target. Look through

the lenses to determine if the

target is centered vertically in the

lens openings.

4) If a centering adjustment is

required, move only the left

spring clip away from the drum

and move left end of the drum

backward and away from the

gear. The gear must be disen-

gaged from the drum cogs. Ro-

tate the drum backward or for-

ward to accomplish adjustment.

Snap the drum back into posi-

tion, re-engaging the gear. Re-

check target alignment by look-

ing through the lenses.

5) Repeat step 4 if necessary.
