Installation! CAUTIONThe LectroCount Remote Display and accessories (whether supplied by Liquid Controls or other) must be installedand operated in accordance with all applicable federal, state, and local construction, electrical, environmentaland safety codes. Failure to do so could result in serious injury or death.This unit is designed for Class I, Division 2, Group C & D areas.Do not install in Class I, Division 1 areas.Installation Requirements• Read this manual prior to start of installation. If youhave any questions, consult with your full servicedistributor or call the Service Department at LiquidControls.• This display should always be securely mounted toa platform or supportive member. Ensure that thedisplay does not experience excessive vibration orshock.• The LectroCount Remote Display is designed to becompatible with a specific LectroCount ElectronicRegister as specified by the customer and asindicated on the Serial Number Tag. No attemptshould be made to use the display with an inputdifferent from the one originally specified.• The LectroCount Remote Display is supplied with a30 foot cable, which should be adequate for mostinstallations. If additional cable is required, cablekits are available from Liquid Controls. It isrecommended that a 4-wire, shielded cable with 22gage wire or larger be used. The maximum lengthof cable allowable is 100 feet.The LectroCount Remote Display is supplied ready forfinal cable termination. Should it be necessary to replacethe cable between the signal source and the remotedisplay, be sure to secure the cable and tighten the coverso as to maintain the vapor seal.Remote Display LabelThe LectroCount Remote Display is shipped with the unitsof measure displayed on the label in Gallons. Theapplication in which the display is being utilized mayrequire a different unit of measure.The LectroCount Remote display is shipped with four (4)additional unit of measure labels. To change the unit ofmeasure, remove the desired label from it’s backing andplace over the “Gallons” label on the display. The areaaround Gallons is recessed and the sticker can easilybe positioned for placement.Figure 3. Remote Display Label4

InstallationMounting DimensionsThe LectroCount Remote Display should be mountedusing the four holes provided in the rear cover. The holesize is designed for use with ¼" screws. It is importantto select a mounting location which will position thedisplay as close to the optimal viewing angle as possible(see Page 6).The diagram below shows the overall dimensions andthe locations of the mounting holes on the LectroCountRemote Display.Figure 4. Remote Display DimensionsNOTE:Dimensions shown are not for construction use.Consult factory when certified Engineering Drawings are required.5

InstallationOptimum Viewing AngleLCD displays have an optimum viewing angle. Displayslose contrast and become more difficult to read at someviewing angles and are easier to read at other angles.Because the viewing angle is limited, a bias is designedinto the module at the time it is manufactured. The resultis a nominal viewing angle which is offset from theperpendicular by a specified amount. The Liquid ControlsLectroCount Remote Display is designed with a bias setto accommodate as wide a viewing area as possible.Optimum viewing with the greatest contrast will occurwhen the display is viewed between 20º above and 40ºbelow horizontal. If the display is viewed outside thisrange, the display contrast will reduce to a point where itreaches an unacceptable viewing level. The horizontal,side to side viewing angle is 40º left and right from center.Figure 5. Optimum Viewing Angle6

InstallationRemote Display Shield Accessory (PN 81879)There are certain applications where sun or bright lightmay produce glare on the display. Use the optional shieldto reduce the effect of glare. This shield fits in place overthe LectroCount Remote Display as shown in Figure 6.The holes in the shield are slotted for ease of installation.Figure 6. Remote Display ShieldFigure 7. Remote Display Shield DimensionsNOTE: Dimensions shown in Inches (to obtain centimeters, multiply values shown by 2.54).Bolt & Torque SpecificationsIt may be necessary to open the Remote Display for thepurpose of changing the decimal point jumper setting(Page 8), or to connect wires to J1 or J2. There are 14bolts on the rear panel of the Remote Display which needto be removed to gain access to the printed circuit board(PCB). When work on the internal components iscomplete, the bolts need to be tightened to the propertorque specification and in the proper sequence to ensurethat the unit is resealed properly to prevent moisture fromentering.Insert each bolt and tighten by hand, then tighten thebolts according to the sequence show below. The boltsshould be tightened to 5-8 In. LBS. (80-128 In. Oz.)Figure 8. Remote Display Torque Pattern.7

InstallationDecimal Point Jumper SettingNOTE: Model E1610 automatically displays the identicaldecimal configuration appearing on the LectroCountLCR-II display. There is no need to adjust the jumperson Model E1610.The LectroCount Remote Display may be configured toshow the decimal point in one of three positions:• Whole Units (No Decimal Point)• Tenth Units• Hundredth UnitsThis is accomplished by moving the J3 and J4 jumperson the Remote Display PCB. The PCB is accessed byremoving the 14 screws on the back of the enclosure.The jumpers are located on the bottom left side of thePCB, to the left of the J2 connector (Figure 9).Once the enclosure is opened, the jumpers may be movedto configure the display according to the LectroCountElectronic Register for which it is designed. See the tablebelow for jumper settings.NOTE: The jumpers need to be in position. Do not removeand discard them. If Whole Units is desired, then J3 andJ4 must BOTH have jumpers in the OFF position.NOTE: If J3 and J4 are BOTH in the ON position, then 2decimal points will appear on the display. This is not avalid jumper configuration.Figure 9.

LCR-II Wiring DiagramLectroCount LCR-II - Select Switch Kit Accessory (PN 82593)This kit is not required for operation of the LectroCountRemote Display with the LectroCount LCR-II. It is anoptional accessory which allows the user to select thevarious displays available from a remote location. Theswitch kit accessory does not connect to the LectroCountRemote Display, it is wired directly into the LectroCountLCR-II.The Select Switch Kit includes the following:• Push Button (& cord grip)• Cord Grip (2)• 4-port Conduit Box• 30 Foot, 2-wire, Shielded CableThe 4-port Conduit Box can be configured as desired.Each port is the same size (½") so the plugs and cord gripand switch may be reconfigured to suit the application.When a location has been determined for the switch kit,mount the conduit box. Route the 30 foot cable providedto the LectroCount LCR-II and connect the cord grip to anavailable port on the back of the LCR-II. Route the freeend of the 30 foot cable through the cord grip on the backof the LCR-II. Connect the two wires for the Select switchto terminal J8 on the LCR-II PCB as shown in Figure 11.RED to Pin 35BLACK to Pin 38.Figure 11.
