GENERAL DESCRIPTION
The Large Display is a versatile display available as a DC volt, current, or
process meter with scaling, serial communications and dual relay outputs. The 5
digit displays are available in either 2.25" or 4" high red LED digits with
adjustable display intensities. The 2.25" high models are readable up to 130 feet.
The 4" high models are readable up to 180 feet. Both versions are constructed
of a NEMA 4X/IP65 enclosure in light weight aluminum.
All models also come with dual Form C relay outputs and RS232 / RS485
serial communications.
SAFETY SUMMARY
All safety regulations, local codes and instructions that appear in this and
corresponding literature, or on equipment, must be observed to ensure personal
safety and to prevent damage to either the instrument or equipment connected to
it. If equipment is used in a manner not specied by the manufacturer, the
protection provided by the equipment may be impaired.

INPUT RANGE JUMPER
This jumper is used to select the proper input range. The input range selected
in programming must match the jumper setting. Select a range that is high
enough to accommodate the maximum signal input to avoid overloads. To
access the jumper, remove the side cover of the meter.
Warning: Exposed line voltage exists on the circuit boards.
Remove all power to the meter and load circuits before accessing
inside of the meter.

INSTALLATION
The meter meets NEMA 4X/IP65 requirements when properly installed.
INSTALLATION ENVIRONMENT
The unit should be installed in a location that does not exceed the operating
temperature. Placing the unit near devices that generate excessive heat should
be avoided. The unit should only be cleaned with a soft cloth and neutral soap
product. Do NOT use solvents.
Continuous exposure to direct sunlight may accelerate the aging process of
the front overlay. Do not use tools of any kind (screwdrivers, pens, pencils, etc.)
to operate the keypad of the unit.
MOUNTING INSTRUCTIONS
This display is designed to
be wall mounted or
suspended from a ceiling
truss or other suitable
structure capable of
supporting the LDA.
Caution should be
exercised when hanging
the display to provide for
the safety of personnel. If
hanging the LDA, run the
suspension cables (or chains)
through the mounting bracket
holes. For wall mounting use
#10-32 size bolts.
