YARWAY LED ILLUMINATOR SYSTEM FOR COLOR-PORT GAUGES
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
2 INTRODUCTION
Yarway LED illuminators are designed to be
mounted readily to the Yarway Color-Port gauge,
as well as most competitive color-port gauges.
All illuminators are complete with a color
screen containing two strips of glass - one red
and one green. Due to the difference in the
index of refraction of light through water and
steam, only the corresponding color is seen:
green for water, red for steam.
Yarway LED illuminators are available in lengths
from 5 ports to 26 ports.
2.1 System description
Yarway LED illuminators comprise five main
components. Use the exploded parts diagrams in
Section 13 as additional reference material.
Illuminator - light source. It is composed of
an anodized, rigid, extruded aluminum that
protects the PC boards.
Bracket - used to mount illuminator to ColorPort gauge. The brackets can be moved up
and down along the extruded body making
assembly and disassembly quick and easy.
Power supply - provides intrinsically safe
power to the LED illuminator. Power supply is
mounted inside an explosion proof enclosure
that is mounted to the illuminator body.
Cordset - used to connect the power supply
to the illuminator. The cordset consists of a
straight female connector and a straight male
connector.
3 AVAILABLE MODELS
Yarway LED illuminators are made to fit/cover
the whole length of the Color-Port gauge. One

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
4 INSPECTION
Safety instructions
Exercise care in handling illuminator parts to
avoid scratching, denting or otherwise damaging
the protective glass. Any marks on the protective
glass, as well as dirt, paint or tape will result
in a reduction of light output. On receipt of an
illuminator, check all components carefully
for damage incurred in shipping. If damage is
evident or suspected, do not attempt installation.
Notify the carrier immediately and request a
damage inspection. Refer to the exploded view
drawing in Section 13 to inventory parts.
5 INSTALLATION
Installation should only be undertaken by
qualified personnel who are familiar with
this equipment. They should have read and
understood all of the instructions in this
manual. The user should refer to relevant
technical data sheets or the product proposal
to obtain dimensional information for the
specific size and model illuminator.
It is the user’s responsibility to assure that
knowledgeable installation personnel plan and
carry out the installation in a safe manner.
The following procedures are some of the
guidelines that should be employed:
5.1 Inspection and cleaning of glass
Prior to installation of an illuminator to a
gauge, the gauge glass should be cleaned and
inspected per instructions as follows:
1. Clean glass within vision ports using a nonabrasive household cleaner. DO NOT use a
wire brush, metal scraper or any device which
could scratch the glass.
2. Inspect the surface of the glass for any signs
of clouding, etching, scratching or physical
damage such as bruises, chips or erosion
that penetrates the outer surface of the
glass. Shining a light at approximately a 45º
angle will aid in detecting some of these
conditions. Light will glisten more brightly
on glass imperfections than the surrounding
glass when reflecting light. Detection of
any such problem areas or surface wear
is sufficient evidence of damage. Do not
proceed with installation with damaged glass.
See appropriate Installation, Operation and
Maintenance manual and replace glass.
2. Check that the level display adjustment
plate (164) is oriented with view slots
towards the wide side of the gauge.
5.3 Installation of unit to gauge
Become familiar with the illuminator components
before proceeding with installation. Refer to the
exploded parts drawing in Section 13, Figures 1
and 2. As well as Figure 5A for general locations,
Figure 5B for division locations, and Figure 5C
for ATEX/IECEx when performing the following
installation instructions.
To assemble the illuminator and level display to a
Color-Port style gauge, follow the steps below:
1. Mount level display to gauge by inserting
mounting slots to the hex screws on the
body of the gauge.
2. Attach the mounting brackets (73A) to the
illuminator body (11) using the screws (100)
and the slider brackets (73) provided. Leave
two slider brackets in the middle-lower half
of the illuminator for the power supply.
3. Align the mounting brackets with the mark
on the back of the illuminator’s body.
4. Firmly tighten down the screws (100)
to secure mounting brackets (73A) to
illuminator body.
5. Mount LED illuminator to gauge by inserting
mounting brackets to the hex screws on the
body of the gauge.
6. Make sure that the LED clusters are aligned
with the ports.
7. Firmly tighten down the hex screws on the
gauge body to hold the illuminator and the
level display to the gauge.
8. Open the cover of the power supply
enclosure and make sure the AC input
voltage selector switch in the power supply
matches the input voltage provided to the
unit (115 VAC or 230 VAC).
9. After voltage selector switch is selecting the
correct input voltage, connect/plug in the AC
wires to Terminal Block 1.
10. Fully close the cover of the enclosure by
hand tightening it.
11. Mount power supply to the illuminator body
using the last two slider brackets you set
aside from step 2.
12. Connect the power supply to the LED
illuminator using the cordset provided.
IMPORTANT FOR HAZARDOUS LOCATION
ONLY
• A flame path seal-off shall be installed within
18 in. of enclosure. see Figure 5B for Division
Locations.
• A flame path seal-off shall be installed directly
to threaded entry of enclosure. see or Figure 5C
for ATEX/IECEx.
• The LED Illuminator contains material
composition capable of igniting the explosive
atmosphere due to physical impact or friction.
Installation shall provide inherent protection
from potential impacts risks by means of
installation location, guards and/or barriers.
5.2 Assembly - pre-installation
1. Check the orientation of the red/green
glass. The green glass must be towards the
wide side of the gauge (see figure 3)
1.1 If colored glass is orientated correctly no
action is required

INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
5.4 Electrical installation
WARNING
DO NOT proceed with electrical installation unless
the illuminator has been mounted to the gauge
according to instructions in Section 5.3. Only
qualified electricians who have read and understood
local and national electrical codes should connect
the illuminator to an electrical source. Failure to
follow any of these instructions may result in death,
severe personal injury, property damage or damage
to the illuminator and gauge.
The electrical installation should be performed
by a qualified electrician and comply with
applicable codes (U.S. - refer to National
Electrical Code NFPA current edition;
Canada - refer to Electrical Code CSA C22) or
other regulations as applicable. The conduit
must run in such a manner that it is not
supported by or does not serve as a support
for the illuminator. The unit must be grounded
before it is operated.
6 OPERATION
Check that all installation procedures
have been completed. Use only qualified,
experienced personnel who are familiar with
illuminators and thoroughly understand the
implications of all the instructions. If the
equipment is used in a manner not specified by
the manufacturer, the protection provided by
the equipment may be impaired.
7.2 Maintenance procedures
Cleaning the protective glass/colored glass-
wash with a non-abrasive soap or detergent
and water using a soft, grit-free cloth or
sponge. When cleaning grease and oil from the
protective glass/colored glass, use a chemical
compatible with silicone rubber only and a soft,
grit-free cloth. DO NOT use solvents such as
acetone, benzene, carbon tetrachloride, dry
cleaning fluid or lacquer thinners since they
will attack the surface of the protective glass/
colored glass and or the gaskets. After the
surface has been cleaned and rinsed of foreign
particles, it may be dried with a clean, soft,
damp chamois or grit-free cloth.
IMPORTANT
DO NOT use hard, rough cloths on the edge of
protective glass/colored glass because they can
scratch the surface. The scratches will result in
reduced light output from the illuminator.
7.3 Troubleshooting
Internal or external corrosion - could be an
indication of a harsh service environment. An
investigation should be carried out immediately
to determine the cause of the problem. It is the
user’s responsibility to choose a material of
construction compatible with both the contained
fluid and the surrounding atmosphere.
All LEDs off - could be an indication of
power failure. Check the power supply and
connections.
7 MAINTENANCE
The user must create maintenance schedules,
safety manuals and inspection details for each
specific installation of an illuminator.
7.1 Preventative maintenance
On all installations the following items should
be evaluated regularly by the user for purposes
of maintenance:
1. Protective glass/colored glass, for signs of
dirt build up, scratches or breakage
2. Mounting bracket for signs of loosening
The user must determine an appropriate
maintenance schedule necessary for his or
her specific application, upon evaluation of
their own operating experience. Realistic
maintenance schedules can only be determined
with full knowledge of the services and
application situation involved.
IMPORTANT
Contact the manufacturer if any part needs to be
replaced.
