DESCRIPTION

The Large Digit Display, Model LDD, is a versatile display which can
increase your productivity by offering your plant floor or production area a
visual display of their current status, such as counting, rate indication, real time,
or any engineering unit required. The LDD is available in either a 4-digit or a
6-digit display version with Red or Green LED displays, that accepts a selection
of personality boards to meet your specific application needs (see Personality
Module Bulletins for more information).

There are four panel wiring knock-outs provided, two 7/8" (22.2 mm) knock­outs and two 1/2"(12.7 mm) knock-outs. Also provided is a removeable cover
located on the rear panel which will expose one open ended cut-out for easy
wire installation.

The LDD has a sealed front panel which meets NEMA 4/IP65 requirements
for wash-down and dusty environments when properly installed. The 3.32"
(84.4 mm) digits are readable to 130 feet (40 M).

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the
manual 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 specified by the manufacturer, the protection
provided by the equipment may be impaired.

Warning: Disconnect all power before installing or removing module.

SET-UP

To place the personality module into the LDD, first remove the rear cover

by unscrewing the two captive fasteners. Then, before installing the module
into the LDD, configure the module for the specific application by SETTING
ALL APPLICABLE DIP SWITCHES AND JUMPERS AT THIS TIME (see

accompanying module data sheet). Place the module on the plastic standoffs
(see figure 1). Push on the four posts as shown in figure 2 until the carrier snaps

into place.

Note: Power should NOT be applied until the terminal block is plugged into the

module AND

the module is properly installed into the Large Digit Display.

Select the proper voltage by setting the switch to either 115 or 230 volts.

Connect the display and power cables on the module to the appropriate
connectors on the power supply board (see figure 2).

To program the Intelligent Meter, three normally open momentary

pushbuttons are connected to “P”, “UP”, “DOWN”, and common of the LDD
(not included with the Intelligent Meter). The Model PGM is a small plastic
case with three normally open momentary pushbuttons and 10 feet (3 M) of
shielded cable, and is well suited for programming the Intelligent Meter
module. Although, any normally open, momentary pushbutton switches can be
used. (SEE APPROPRIATE MODULE LITERATURE FOR SET-UP AND

OTHER CONNECTIONS.)

To remove module from the LDD, disconnect the display and power cables,

then remove the carrier from the standoffs by disengaging the tabs and
simultaneously lifting the carrier. Repeat this until the module has cleared all 4
standoffs.

INSTALLATION ENVIRONMENT

The unit should be installed in a location that does not exceed the maximum

operating temperature and provides good air circulation. Placing the unit near
devices that generate excessive heat should be avoided.

The LDD may be cleaned using alcohol compounds such as Isopropanol or

methanol. Also, liquid glass cleaners may be used if they do NOT contain
ammonia.

NOTE: MINIMAL EXPOSURE OF KETONE SOLVENTS TO THE LDD IS

GOING TO CAUSE A WHITENING OF THE DISPLAY OVERLAY.

Continuous exposure to direct sunlight may accelerate the aging process of

the bezel.

The LDD is intended to be mounted into an enclosed panel with a gasket to

provide a water-tight seal. A gasket and ten 10 to 32 kep nuts are provided for
easy installation. The recommended minimum panel thickness for NEMA
4/IP65 applications is 0.125" (3.2 mm). Thinner panels may be used but may
distort and not provide a water-tight seal.

For ease of installation, the cardboard template (supplied with the LDD) may

be used to mark the holes and cut-out locations on the panel. After the panel
cut-out has been completed and deburred, insert the unit with the panel gasket,
into the panel as depicted in the drawing (see figure 3). Install the ten kep nuts
and tighten evenly for uniform gasket compression.

By using additional hardware, the LDD can be surface-wall mounted,

suspended, or bottom mounted. To surface-wall mount the unit, two sets of
MB6 brackets are required. To suspend or bottom mount the unit, one set of
MB6 brackets is required.
