DESCRIPTION

The CUB4 offers a large display in a miniature package with a choice of three

displays; reflective, red backlight or green backlight.

The backlight versions require power from an external 9–28 VDC supply. The
optional power supply (MLPS) is designed to be attached directly to the rear of
the CUB4 and is powered from an 85–250 VAC source.

The CUB4 series has a lightweight, high impact plastic case with a clear
viewing window. The sealed front panel with the silicone rubber reset button
meets NEMA 4X/IP65 specifications for wash-down and/or dusty environments,
when properly installed.

EMC INSTALLATION GUIDELINES

Although Red Lion Controls Products are designed with a high degree of

immunity to Electromagnetic Interference (EMI), proper installation and wiring
methods must be followed to ensure compatibility in each application. The type
of the electrical noise, source or coupling method into a unit may be different
for various installations. Cable length, routing, and shield termination are very
important and can mean the difference between a successful or troublesome
installation. Listed are some EMI guidelines for a successful installation in an
industrial environment.

1. A unit should be mounted in a metal enclosure, which is properly connected
to protective earth.

2. Use shielded cables for all Signal and Control inputs. The shield connection
should be made as short as possible. The connection point for the shield
depends somewhat upon the application. Listed below are the recommended
methods of connecting the shield, in order of their effectiveness.
a. Connect the shield to earth ground (protective earth) at one end where the

unit is mounted.

b. Connect the shield to earth ground at both ends of the cable, usually when

the noise source frequency is over 1 MHz.

3. Never run Signal or Control cables in the same conduit or raceway with AC
power lines, conductors, feeding motors, solenoids, SCR controls, and
heaters, etc. The cables should be run through metal conduit that is properly

grounded. This is especially useful in applications where cable runs are long
and portable two-way radios are used in close proximity or if the installation
is near a commercial radio transmitter. Also, Signal or Control cables within
an enclosure should be routed as far away as possible from contactors,
control relays, transformers, and other noisy components.

4. Long cable runs are more susceptible to EMI pickup than short cable runs.

5. In extremely high EMI environments, the use of external EMI suppression
devices such as Ferrite Suppression Cores for signal and control cables is
effective. The following EMI suppression devices (or equivalent) are
recommended:

Fair-Rite part number 0443167251 (RLC part number FCOR0000)
Line Filters for input power cables:

Schaffner # FN2010-1/07 (Red Lion Controls # LFIL0000)

6. To protect relay contacts that control inductive loads and to minimize radiated
and conducted noise (EMI), some type of contact protection network is
normally installed across the load, the contacts or both. The most effective
location is across the load.
a. Using a snubber, which is a resistor-capacitor (RC) network or metal oxide

varistor (MOV) across an AC inductive load is very effective at reducing
EMI and increasing relay contact life.

b. If a DC inductive load (such as a DC relay coil) is controlled by a transistor

switch, care must be taken not to exceed the breakdown voltage of the
transistor when the load is switched. One of the most effective ways is to
place a diode across the inductive load. Most RLC products with solid
state outputs have internal zener diode protection. However external diode
protection at the load is always a good design practice to limit EMI.
Although the use of a snubber or varistor could be used.
RLC part numbers: Snubber: SNUB0000
Varistor: ILS11500 or ILS23000

7. Care should be taken when connecting input and output devices to the
instrument. When a separate input and output common is provided, they
should not be mixed. Therefore a sensor common should NOT be connected
to an output common. This would cause EMI on the sensitive input common,
which could affect the instrument’s operation.

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.

Do not use tools of any kind (screwdrivers, pens, pencils, etc.) to operate
the keypad of the unit.

Installation

The CUB4 series of products meet NEMA 4X/IP65 requirements for indoor
use, when properly installed. The units are intended to be mounted into an
enclosed panel. The viewing window and reset button are factory sealed for a
washdown environment. A sponge rubber gasket and mounting clip are
provided for sealing the unit in the panel cut-out.

The following procedure assures proper installation:

1. Cut panel opening to specified dimensions. Remove burrs and clean around

panel opening.

2. Carefully remove the center section of the panel gasket and discard.

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

3. Assemble nut fastener first and then mounting screw onto both sides of

mounting clip. Tip of screw should not project from hole in mounting clip.

4. Install CUB4 unit through the panel cut-out until front bezel flange contacts

the panel-mounted gasket.

5. Slide the mounting clip over the rear of the unit until the mounting clip is

against the back of the panel. The mounting clip has latching features which

engage into mating features on the CUB4 housing.

Note: It is necessary to hold the unit in place when sliding mounting clip

into position.

6. Alternately tighten each screw to ensure uniform gasket pressure. Visually
inspect the front panel gasket. The gasket should be compressed about 75 to
80% of its original thickness. (Recommended torque is 28 to 36 in-oz.) If
not, gradually turn mounting screws to further compress gasket.

7. If gasket is not adequately compressed, and mounting screws can no longer
be turned, loosen mounting screws and check that mounting clip is latched
as close as possible to panel.
Repeat procedure for tightening mounting screws.
