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.

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.

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.

WIRING CONNECTIONS

All conductors should meet voltage and current ratings for
each terminal. Also cabling should conform to appropriate
standards of good installation, local codes and regulations. It is
recommended that power supplied to the unit (AC or DC) be
protected by a fuse or circuit breaker.

The electrical connections are made via screw-clamp terminals
located on the back of the unit. When wiring the unit, use the
label to identify the wire position with the proper function. Strip
the wire, leaving approximately ¼" of bare wire (stranded wires
should be tinned with solder). Insert the wire into the screw­clamp terminal and tighten the screw until the wire is clamped
tightly. Each terminal can accept up to two #14 AWG wires.

CUB4LP/CL SIGNAL INPUT

The current range is selected by setting DIP switch S1 to the OFF position
for a 4 to 20 mA input or ON for a 10 to 50 mA input. Attach the signal wires
to terminals 3 (SIG-) and 4 (SIG+) observing the correct polarity. The (SIG-)
signal input circuit is not reverse polarity protected.

Backlight Power (CUB4CL only)

Attach a 9 to 28 VDC supply to terminals 1 (COM) and 2 (V+) to power the
backlight. Terminals 3 (SIG-) and 1 (COM) are AC coupled with a capacitor.
This limits the isolation between these terminals to 50 VDC maximum.

SPAN ADJUSTMENTS

Span is defined as the numerical range that the display traverses, disregarding
the decimal point, when the input signal is varied from minimum to maximum
(4 to 20 mA or 10 to 50 mA). For example; if a unit is to display 250 @ 4 mA
and 1000 @ 20 mA, the span is 750 (the difference between 250 and 1000). Had
the minimum display been -250, the span would be 1250 (1000 - (-250) = 1250).
The CUB4LP/CL can be set to operate over a wide span range by adjusting the
Coarse and Fine Span adjustment pots. The Coarse Span pot is used to get the
display to within a couple of counts of the desired reading, and the Fine Span
pot is used to adjust for the exact reading.

OFFSET ADJUSTMENTS

The minimum currents are not zero based with 4 to 20 mA and 10 to 50 mA
signals. To obtain a zero minimum display reading, the display must be offset.
The display on the CUB4LP/CL can be offset by adjusting the Coarse and Fine
Offset pots.

DECIMAL POINT POSITION SELECTION

The decimal point position is DIP switch selectable for one of three locations.
The CUB4LP/CL can be set up to read in 10ths, 100ths, or 1000ths. If all the
DIP switches are set to the “OFF” position, no decimal point will appear on the
display. The DIP switches are located at the rear of the unit.

APPLICATION EXAMPLE

Operation of a refinery process required a local display of the position of a
remote pipeline valve. The display would indicate 0 (zero) when the valve was
fully closed with an input signal of 4 mA. When the valve was fully open the
display would indicate 100 with an input signal of 20 mA.

Both the CUB4LP and the CUB4CL meet the necessary requirements.

CALIBRATING THE DISPLAY

Calibrating the CUB4LP/CL requires either an accurate adjustable constant
current supply or the CUB4LP/CL can be installed and scaled with the process
sensor connected to the CUB4LP/CL. To calibrate the unit, proceed as follows.

1. Set DIP switching for the desired current range.

2. Select the desired decimal point position.

3. Apply the minimum input signal to the CUB4LP/CL and adjust the COARSE

OFFSET to display the approximate desired minimum value.

4. Apply the maximum input signal to the CUB4LP/CL and adjust the COARSE

SPAN to display the approximate desired maximum value.

5. Repeat steps 3 and 4 until the minimum and maximum values are within the

desired values.

6. Apply the minimum input signal to the CUB4LP/CL and adjust the FINE

OFFSET to display the exact desired minimum value.

7. Apply the maximum input signal to the CUB4LP/CL and adjust the FINE

SPAN to display the exact desired maximum value.

8. Apply the minimum input signal and verify that the display indicates

correctly.

9. Apply the maximum input signal and verify that the display indicates

correctly.

10. Repeat Steps 6 through 9 until display reads exact.

Note: The CUB4LP/CL display is factory calibrated to indicate 0.0 to 100.0

with an input of 4 to 20 mA at approximately 25°C.
