DESCRIPTION

The CUB4LP and CUB4CL are additions to the CUB4 product line. The
CUB4LP uses a 4 to 20 mA or a 10 to 50 mA input signal as operating power.
The input signal is also used to power the backlighting on the CUB4LP40 unit.
The CUB4CL uses a 4 to 20 mA or a 10 to 50 mA input signal to power the unit.
An external power supply is used to power the CUB4CL backlighting to provide
a brighter, more consistent display and a lower compliance voltage.

The units have a 3½-digit LCD display with 0.6" (15.2 mm) high digits and
a DIP switch selectable decimal point. The CUB4LP display is available in
positive image reflective (dark digits, reflective background) or positive image
transflective (dark digits, illuminated background) with red backlighting. The
CUB4CL display is available in positive image transflective (dark digits,
illuminated background) with red or yellow/green backlighting or negative
image transmissive (illuminated digits, dark background) with red or yellow/
green backlighting.

The ability to scale the display allows indication in any desired unit of
measurement such as temperature, pressure, humidity, fluid flow, etc. The unit
is calibrated at the factory with 0.0 displayed @ 4 mA input and 100.0 displayed
@ 20 mA input.

The units are contained in a lightweight, high impact plastic case with a clear
viewing window. When properly installed, the sealed front panel meets NEMA
4X/IP65 specifications for wash-down and dusty environments.

CAUTION: Risk of Danger.

Read complete instructions prior to

installation and operation of the unit.

DIMENSIONS In inches (mm)

Note: Recommended minimum clearance (behind the panel) for

mounting clip installation is 2.15" (54.6) H x 3.00" (76.2) W.

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 - EXPLOSION HAZARD - SUBSTITUTION
OF ANY COMPONENTS MAY IMPAIR SUITABILITY FOR
CLASS I, DIVISION 2 / CLASS II, DIVISION 2 / CLASS III, DIVISION 2

SPECIFICATIONS

1. DISPLAY: 3½-digit (-1999 to 1999), 0.6" (15.2 mm) high digits.

The CUB4LP is available with a positive image reflective LCD or a red

backlit positive image transflective LCD. The intensity of the backlighting

will vary with the input signal.

The CUB4CL is available with a positive image transflective LCD with red

or yellow/green backlighting or a negative image transmissive with red or

yellow/green backlight.

A minus sign is displayed when the indicator is adjusted for a negative offset.

Overrange: Overrange is indicated by a “1” in the most significant digit and

the blanking of the three least significant digits.

2. EXTERNAL BACKLIGHT POWER: (CUB4CL only)

9 - 28 VDC, @ 35 mA typ., 50 mA max. Power Supplies must be Class 2

(NEC) or SELV rated. Above 26 VDC, derate the operating temperature to

50°C.

3. DECIMAL POINTS: Three DIP switch selectable, decimal point positions

allow the display to be read in tenths, hundredths or thousandths.

INSTALLATION

When properly installed, the CUB4LP/CL meets
NEMA 4X/IP65 requirements for indoor use. The
units are intended to be mounted into a suitably rated
enclosed panel. A sponge rubber gasket, mounting
clip, two screws, and nut fasteners are provided to
install and seal the unit in the panel cutout.

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 bezel should be cleaned only with a soft cloth
and neutral soap product. Do NOT use solvents.

Continuous exposure to direct sunlight may
accelerate the aging process of the bezel.

The following procedure assures proper installation:

1. Cut the panel opening to the specified dimensions.

Remove burrs and clean the panel opening.

2. Slide nut fastener into slot on mounting clip and then insert

mounting screw through nut on both sides of mounting clip. The

tip of mounting screw should not project through hole on clip.

3. Slide the panel gasket over the rear of the unit to the back of the bezel.

Install CUB4LP/CL unit through panel cutout.

4. Slide mounting clip over rear of unit until the clip is against back of panel.

The mounting clip and CUB4LP/CL housing have a latching feature to hold

the unit in place until tightened.

Note: Hold the CUB4LP/CL front bezel in place when sliding the mounting

5. Alternately tighten each mounting screw to ensure uniform gasket pressure.

Visually inspect the gasket for proper seal. The gasket should be compressed

to approximately 75 to 80% of its original thickness.

(Recommended torque is 28 to 36 in-oz.)

clip into position.

6. If the gasket is not adequately compressed and the mounting screws cannot
be tightened any further, loosen the mounting screws and insure that the clip
is latched as closely as possible to the panel.

7. Repeat Step #6 for tightening the mounting screws.
