1 ABOUT THE MANUAL
This manual has been prepared as an aid and
guide for personnel involved in installation or
maintenance. All instructions must be read and
understood thoroughly before attempting any
installation, operation or maintenance.
SAFETY INSTRUCTIONS
Emerson does not have any control over the
manner in which its illuminators are handled,
installed or used and Emerson cannot and does
not warrant or guarantee that an illuminator is
suitable for or compatible with the user's specific
application.
WARNING
Vessel fluids may be pressurized in the gage on
which the illuminator is being attached.
Fluids can exit vessel connections unexpectedly
due to apparatus or material failure. Safety
glasses should be worn when installing an
illuminator. Failure to follow any instruction could
possibly result in a malfunction of the illuminator
resulting in a loss of ability to read fluid level or
failure of the liquid level gage resulting in leakage
causing serious personal injury, electric shock or
property damage.
2 INTRODUCTION
Penberthy illuminators are designed to be
mounted readily and able to fit channelled
indicator assemblies on Penberthy Multiview™
magnetic liquid level meters and any style
Penberthy flat glass liquid level gage.
Single and double section illuminators provide
uniform light distribution over the entire length
of the liquid level gage assemblies.
Single illuminators for Multiview™ magnetic
gages are constructed in lengths up to four
feet. Two illuminators can be butted against
one another to cover up to eight feet in length
continuously.
2.1 System description
Penberthy illuminators comprise four basic
components. Use the exploded parts view in
Section 11 as additional reference material.
Illuminator body/cover: a rigid, aluminum
protective structure that supports and houses
the illuminating elements of the illuminator.
The reflector wedge is positioned between the
cover and body by a bolting system such that
the light dispersion is maximized.
Illuminator housing: provides the electrical
connection from the power source to the
lamp. Located within the illuminator body, the
housing holds the lamp in position.
Reflector wedge: machined and polished
PMMA light guide. Used to channel light from
the lamp into a long plane (light bar).
Brackets (flat glass gage only): use a bolting
system to mount illuminator to the flat glass
gage cover. Bolts pass through the reflector
wedge to affix the illuminator to the centerline
of gage vision (transparent style gage only).
3 AVAILABLE MODELS
Penberthy flat glass gage illuminators are
available in single section units, double
section units and in combinations of single and
double section units for three or more section
gages. Single and double section frost proof
illuminators can be used in flat glass cryogenic
applications.
Wedge depth is a critical factor when applying
an illuminator in cryogenic applications. If
the depth is too shallow, frost may build up
on the end of the wedge making it difficult or
impossible to read the fluid level.
Optional structure
The standard illuminator rating is 60 watts at
115 Vac. Other illuminators are listed in the
options in Table 2.

Illuminator nominal rating Applicable voltage range
115 V AC 108 Vac - 125 V AC
230 V AC 207 Vac - 250 V AC
To determine the maximum allowable voltage within the design limits stated in the tables, the
user should consult the lamp manufacturer or, when provided, the specifically stated design limits
on a product proposal.
DANGER
NEVER exceed these design ratings or application data. Exceeding design ratings or application data
may result in creating excessive heat and potential ignition of volatile fluids that could cause death,
serious personal injury and/or property damage.
3.3 Steam application
Penberthy light guides are constructed of PMMA which has a degradation temperature of
225°F (107°C). Should an illuminator be purchased for steam or other high temperature
application gage usage, the steam or process temperature must be low enough and/or a cooling
system must be used to maintain 225°F (107°C) or less at illuminator surfaces.

4 INSPECTION
Operational note: exercise care in handling
illuminator parts to avoid scratching, denting,
or otherwise damaging the polished edge of
the reflector wedge. Any marks on the polished
edge, as well as dirt, paint or tape will result in
a reduction of light output.
Upon 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 damage inspection.
Refer to the exploded view drawing in
Section11 to inventory parts.
4.1 User’s rating inspection
The user should confirm that:
1. The illuminator size, rating and model
number stamped on nameplate (163)
conforms to the description on the user’s
purchase order.
2. The operating conditions described in
the purchase order agree with the actual
operating conditions at the installation site.
3. The actual operating conditions at the
installation site are within the application
data shown on the relevant technical data
sheet or product proposal referred to
previously.
4. The materials of construction of the
illuminator are compatible with the
surrounding atmosphere in the specific
application.
SAFETY INSTRUCTIONS
If the size, model or performance data of the
illuminator as received does not conform with
any of the criteria above, do not proceed with
installation. Contact an authorized Penberthy
distributor for assistance. The incorrect
illuminator voltage can result in unacceptable
performance and potential damage to the
illuminator.
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 product proposal to obtain dimensional
information for the specific size and model
illuminator.
Illuminator installation
Refer to Figures 1 and 2.
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 gage,
the gage glass should be cleaned and inspected
per instructions as follows:
1. Clean glass within vision slot 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, checks or
erosion that penetrates the outer surface of
the glass. Shining a light at approximately a
45° 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.

5.3 Electrical installation
WARNING
DO NOT proceed with electrical installation
unless the illuminator has been mounted to the
gage according to instructions in Section 5.2
and is grounded. 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 the
above instructions can result in damage to the
illuminator, gage, surrounding property or severe
physical injury to personnel.
The electrical installation should be performed
by a qualified electrician and comply with
applicable codes (U.S. - refer to National
Electric Code NFPA current edition; Canada refer to Canadian Electrical Code CSA C22) or
other regulations as applicable. The conduit
must be run in such a manner that it is not
supported by or does not serve as a support
forthe illuminator.
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 the tables and all the
instructions. Check that the illuminator has
sufficient light output over the entire visible
length of the liquid level gage or magnetic
gage.
7 MAINTENANCE
DANGER
Use only qualified, experienced personnel who
are familiar with illuminators and thoroughly
understand the implications of the tables and
all the instructions. DO NOT proceed with any
maintenance unless: 1) the gage assembly has
been relieved of pressure or vacuum, has been
allowed to reach ambient temperature and
has been drained or purged of all fluids and 2)
electrical power has been turned off. Failure to
doso can cause death, serious personal injury
orproperty damage.
7.1 Preventative maintenance
On all installations, the following items should
be evaluated regularly by the user for purposes
of maintenance:
1. Reflector, for signs of dirt build up,
scratches or breakage.
2. Mounting Brackets or cover flange nuts,
forsigns 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.
7.2 Accessing maintenance items
Refer to Table 4.
7.3 Maintenance procedures
Cleaning the reflector: wash with a non-
abrasive soap or detergent and water using a
soft, grit-free cloth or sponge. When cleaning
grease and oil from reflector, use only hexane,
kerosene or aliphatic naphtha (no aromatic
content) 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
reflector. After 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
edge of reflector because they will scratch the
polished surface. The scratches will result in
reduced light output of the illuminator.
Cleaning the lens: wash with a commercial
glass cleaner. DO NOT use a wire brush, metal
scraper or any device that might scratch the
glass.
7.4 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.
The user must create maintenance schedules,
safety manuals and inspection details for each
