Model Numbers
Two LectroCount®Remote Display Models are available
for interface to Liquid Controls LectroCount Electronic
Registers. Ensure that the model number of the
LectroCount Remote Display is compatible with the
LectroCount Electronic Register prior to installation. If
the device does not match the model number, the system
will not work and may be damaged when power is applied.
An identification label appears on the top of the remote
display (Figure 1). This label designates the device for
which the remote display is designed. It will not work
with other devices. The label also contains the Serial
Number of the unit. This information will be useful when
contacting Liquid Controls for assistance.

Installation
Installation Requirements
• Read this manual prior to start of installation. If you
have any questions, consult with your full service
distributor or call the Service Department at Liquid
Controls.
• This display should always be securely mounted to
a platform or supportive member. Ensure that the
display does not experience excessive vibration or
shock.
• The LectroCount Remote Display is designed to be
compatible with a specific LectroCount Electronic
Register as specified by the customer and as
indicated on the Serial Number Tag. No attempt
should be made to use the display with an input
different from the one originally specified.
• The LectroCount Remote Display is supplied with a
30 foot cable, which should be adequate for most
installations. If additional cable is required, cable
kits are available from Liquid Controls. It is
recommended that a 4-wire, shielded cable with 22
gage wire or larger be used. The maximum length
of cable allowable is 100 feet.
The LectroCount Remote Display is supplied ready for
final cable termination. Should it be necessary to replace
the cable between the signal source and the remote
display, be sure to secure the cable and tighten the cover
so as to maintain the vapor seal.
Remote Display Label
The LectroCount Remote Display is shipped with the units
of measure displayed on the label in Gallons. The
application in which the display is being utilized may
require a different unit of measure.
The LectroCount Remote display is shipped with four (4)
additional unit of measure labels. To change the unit of
measure, remove the desired label from it’s backing and
place over the “Gallons” label on the display. The area
around Gallons is recessed and the sticker can easily
be positioned for placement.

!CAUTION
The LectroCount Remote Display and accessories (whether supplied by Liquid Controls or other) must be installed
and operated in accordance with all applicable federal, state, and local construction, electrical, environmental
and 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.

Mounting Dimensions
The LectroCount Remote Display should be mounted
using the four holes provided in the rear cover. The hole
size is designed for use with ¼" screws. It is important
to select a mounting location which will position the
display as close to the optimal viewing angle as possible
(see Page 6).
The diagram below shows the overall dimensions and
the locations of the mounting holes on the LectroCount
Remote Display.
Installation
NOTE: Dimensions shown are not for construction use.
Consult factory when certified Engineering Drawings are required.
Figure 4. Remote Display Dimensions

Installation
LCD displays have an optimum viewing angle. Displays
lose contrast and become more difficult to read at some
viewing angles and are easier to read at other angles.
Because the viewing angle is limited, a bias is designed
into the module at the time it is manufactured. The result
is a nominal viewing angle which is offset from the
perpendicular by a specified amount. The Liquid Controls
LectroCount Remote Display is designed with a bias set
Optimum Viewing Angle
to accommodate as wide a viewing area as possible.
Optimum viewing with the greatest contrast will occur
when the display is viewed between 20º above and 40º
below horizontal. If the display is viewed outside this
range, the display contrast will reduce to a point where it
reaches an unacceptable viewing level. The horizontal,
side to side viewing angle is 40º left and right from center.

Installation
Bolt & Torque Specifications
There are certain applications where sun or bright light
may produce glare on the display. Use the optional shield
to reduce the effect of glare. This shield fits in place over
the LectroCount Remote Display as shown in Figure 6.
The holes in the shield are slotted for ease of installation.
Remote Display Shield Accessory (PN 81879)
It may be necessary to open the Remote Display for the
purpose of changing the decimal point jumper setting
(Page 8), or to connect wires to J1 or J2. There are 14
bolts on the rear panel of the Remote Display which need
to be removed to gain access to the printed circuit board
(PCB). When work on the internal components is
complete, the bolts need to be tightened to the proper
torque specification and in the proper sequence to ensure
that the unit is resealed properly to prevent moisture from
entering.
Insert each bolt and tighten by hand, then tighten the
bolts according to the sequence show below. The bolts
should be tightened to 5-8 In. LBS. (80-128 In. Oz.)
NOTE: Dimensions shown in Inches (to obtain centimeters, multiply values shown by 2.54).

Installation
Decimal Point Jumper Setting
NOTE: Model E1610 automatically displays the identical
decimal configuration appearing on the LectroCount
LCR-II display. There is no need to adjust the jumpers
on Model E1610.
The LectroCount Remote Display may be configured to
show the decimal point in one of three positions:
• Whole Units (No Decimal Point)
• Tenth Units
• Hundredth Units
This is accomplished by moving the J3 and J4 jumpers
on the Remote Display PCB. The PCB is accessed by
removing the 14 screws on the back of the enclosure.
The jumpers are located on the bottom left side of the
PCB, to the left of the J2 connector (Figure 9).
Once the enclosure is opened, the jumpers may be moved
to configure the display according to the LectroCount
Electronic Register for which it is designed. See the table
below for jumper settings.
NOTE: The jumpers need to be in position. Do not remove
and discard them. If Whole Units is desired, then J3 and
J4 must BOTH have jumpers in the OFF position.
NOTE: If J3 and J4 are BOTH in the ON position, then 2
decimal points will appear on the display. This is not a
valid jumper configuration.

For use with LectroCount LCR-II
Once the display is mounted, the factory installed
cable should be routed to the LectroCount LCR-
II. Choose an unused port on the LCR-II and
connect the cord grip provided. Route the cable
through the cord grip and connect the cable to
the J12 Connector on the LCR-II PCB as shown
in Figure 10.

*If the power supplied to the LCR-II ever exceeds
+24VDC, then the remote display should be powered
from Pin 32 on J8, +5VDC.
LectroCount LCR-II - Select Switch Kit Accessory (PN 82593)
This kit is not required for operation of the LectroCount
Remote Display with the LectroCount LCR-II. It is an
optional accessory which allows the user to select the
various displays available from a remote location. The
switch kit accessory does not connect to the LectroCount
Remote Display, it is wired directly into the LectroCount
LCR-II.
The Select Switch Kit includes the following:
• Push Button (& cord grip)
• Cord Grip (2)
• 4-port Conduit Box
• 30 Foot, 2-wire, Shielded Cable
The 4-port Conduit Box can be configured as desired.
Each port is the same size (½") so the plugs and cord grip
and 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 provided
to the LectroCount LCR-II and connect the cord grip to an
available port on the back of the LCR-II. Route the free
end of the 30 foot cable through the cord grip on the back
of the LCR-II. Connect the two wires for the Select switch
to terminal J8 on the LCR-II PCB as shown in Figure 11.

When a delivery is active, pressing the Select Switch will
cause the display to show the current flow rate. After 5
seconds, the display returns to current flow total.
