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 COARSEOFFSET to display the approximate desired minimum value.4. Apply the maximum input signal to the CUB4LP/CL and adjust the COARSESPAN to display the approximate desired maximum value.5. Repeat steps 3 and 4 until the minimum and maximum values are within thedesired values.6. Apply the minimum input signal to the CUB4LP/CL and adjust the FINEOFFSET to display the exact desired minimum value.7. Apply the maximum input signal to the CUB4LP/CL and adjust the FINESPAN to display the exact desired maximum value.8. Apply the minimum input signal and verify that the display indicatescorrectly.9. Apply the maximum input signal and verify that the display indicatescorrectly.10. Repeat Steps 6 through 9 until display reads exact.Note: The CUB4LP/CL display is factory calibrated to indicate 0.0 to 100.0with an input of 4 to 20 mA at approximately 25°C.BLOCK DIAGRAMPROCESSCIRCUITRYS4 S3 S2SIG-SIG++VDCCOMS18.25Ω12.7Ω COARSESPANGND1234BACKLIGHTFINEOFFSETOFFSETCOARSEFINESPAN-V+V0.1 μf50 VDC(CL ONLY)(CL ONLY)Connection forCUB4LP40DECIMAL POINT POSITION SELECTIONThe 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 theDIP switches are set to the “OFF” position, no decimal point will appear on thedisplay. The DIP switches are located at the rear of the unit.APPLICATION EXAMPLEOperation of a refinery process required a local display of the position of aremote pipeline valve. The display would indicate 0 (zero) when the valve wasfully closed with an input signal of 4 mA. When the valve was fully open thedisplay would indicate 100 with an input signal of 20 mA.Both the CUB4LP and the CUB4CL meet the necessary requirements.VALVECONTROLDEVICE+ +--CUB4LPSIG +COMM(SIG -)TROUBLESHOOTINGFor further technical assistance, contact technicalsupport at the appropriate company numbers listed.Red Lion ControlsHeadquarters20 Willow Springs CircleYork PA 17406Tel +1 (717) 767-6511Fax +1 (717) 764-0839Red Lion ControlsChinaUnit 302, XinAn PlazaBuilding 13, No.99 Tianzhou RoadShangHai, P.R.
