2 INTRODUCTION
Penberthy LED illuminators are designed to
be readily mounted and able to fit any style of
Penberthy flat glass liquid level gauges, as well
as most competitor’s flat glass gauges.
Penberthy LED illuminators provide uniform
light distribution over the entire length of
liquid level gauge assemblies. Penberthy LED
illuminators are available in lengths from 6"
to 104" in multiples of 2" (for flat glass gauges).
2.1 System description
Penberthy LED illuminators are comprised
of four main components. Use the exploded
diagram view in Sections 13-15 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 level
gauge. There are three types of brackets:
standard transparent, reflex, and TSL/TSM.
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.

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. 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 carrier immediately and request damage
inspection. Refer to the exploded view diagram
in Sections 13-15 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 Penberthy
dimension sheets or Penberthy 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
Penberthy recommends that prior to
installation of an illuminator to a gauge, that
the gauge glass 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 devise
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.
5.2 Installation of unit to gauge
Become familiar with the illuminator
components before proceeding with
installation. Refer to the exploded parts
diagram, ISO and top views in Section 13 for
transparent gauges, Section 14 for reflex
gauges, and Section 15 for TSL/TSM gauges.
As well as Figure 4A for general locations,
4B for division locations, and 4C for ATEX/
IECEx when performing the following
installation instructions.
To assemble the illuminator to a transparent
