The CUB4LP and CUBA4CL are additions to the CUB4 product line. The CUBALP 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 extemal power supply is used to power the CUB4CL backlighting to provide a bnghter, more consistent display and a lower compliance voltage. 

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.

## _**INSTALLATION**_ 

When properly installed, the CUB4LP/CL meets NEMA 4X/IP65 requirements for indoor use. The units are intended to be mounted into an 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 clip into position._ 

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.) 

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 this unit is 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 the unit may be different for various installations. Cable length, routing and shield termination are very important and can mean the difference between a successful installation or a troublesome installation. Listed below are some EMC guidelines for successful installation in an industrial environment. 

1. Use shielded (screened) cables for all Signal and Control inputs. The shield (screen) pigtail 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 only at the panel where the unit is mounted to earth ground (protective earth). 

- b. Connect the shield to earth ground at both ends of the cable, usually when the noise source frequency is above 1 MHz. 

- c. Connect the shield to common of the unit and leave the other end of the shield unconnected and insulated from earth ground. 

2. 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 in 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. 

3. 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. In extremely high EMI environments, the use of external EMI suppression devices, such as ferrite suppression cores, is effective. Install them on Signal and Control cables as close to the unit as possible. Loop the cable through the core several times or use multiple cores on each cable for additional protection. Install line filters on the power input cable to the unit to suppress power line interference. Install them near the power entry point of the enclosure. The following EMI suppression devices (or equivalent) are recommended: Ferrite Suppression Cores for signal and control cables: 

- Fair-Rite # 0443167251 (RLC #FCOR0000) TDK # ZCAT3035-1330A Steward #28B2029-0A0 

- Line Filters for input power cables: Schaffner # FN610-1/07 (RLC #LFIL0000) Schaffner # FN670-1.8/07 Corcom #1VR3 

_**Note:** Reference manufacturer’s instructions when installing a line filter._ 

5. Long cable runs are more susceptible to EMI pickup than short cable runs. Therefore, keep cable runs as short as possible. 

## _**WIRING CONNECTIONS**_ 

**==> picture [315 x 182] intentionally omitted <==**

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. 

WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT EQUIPMENT UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE NON-HAZARDOUS. 

**==> picture [43 x 37] intentionally omitted <==**

_THIS EQUIPMENT IS SUITABLE FOR USE IN: Class I, Division 2, Groups A, B, C, and D Class II, Division 2, Groups F and G Class III, Division 2 or Non Hazardous locations._ 

_**3**_ 

## _**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. 

**==> picture [140 x 112] intentionally omitted <==**

## _**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. 

## **BLOCK DIAGRAM** 

**==> picture [257 x 176] intentionally omitted <==**

_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._
