YARWAY
LED ILLUMINATOR SYSTEM FOR COLOR-PORT GAUGES
INSTALLATION, OPERATION AND MAINTENANCE INSTRUCTIONS
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 non-
abrasive 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.
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.
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.
5.2 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
1.2 If colored glass is not oriented correctly
the LED illuminator must be mounted up
side down. See 5.3 Installation of unit to
gauge for mounting instructions.
2. Check that the level display adjustment
plate (164) is oriented with view slots
towards the wide side of the gauge.
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.
