Installation Overview
Meters with LCR (factory installed)
In many instances, the LCR will be factory installed on a
Liquid Controls meter, along with a strainer/air eliminator
and security valve. In such cases, the user may proceed
to page 10 of this manual “Wiring the LCR” after verifying
that the truck electrical system meets the specifications
listed below.
Field retrofit of LCR to existing meters
For field installation of the LCR to a meter the steps listed
below, and described in this manual, should be followed.
A typical truck installation includes the following steps:
• Ensure that the truck electrical system meets
specifications
• Remove existing mechanical registration equipment
• Remove manual preset valve
• Install an electronically controlled security/preset
valve
• Mount LCR to the meter
• Install optional peripheral accessories including
electronic temperature/volume
compensation (ETVC) kit, odometer pulser, remote
START/STOP switch, etc…
• Route factory supplied cables from LCR to truck cab
• Mount printer in cab
• Connect printer and LCR to truck’s
accessory circuit (12 VDC)
Electrical check for Truck Installations
Before beginning the installation, make sure that the truck
electrical system meets the minimum requirements to
correctly power the LCR. The truck system should
produce at least 12.6 VDC to reliably power the LCR
and the valve control solenoids. Truck systems that do
not meet this requirement need to be serviced to ensure
that the LCR will be reliably powered. The LCR computer
will power down if the voltage drops below 9 VDC.
The truck system must meet the following requirements:
• Make sure that, with the truck running at low idle
and ALL accessories on (including the hose reel),
the voltage does not drop below 9 volts.
• Be sure that all radio antennas have been installed
in accordance with the manufacturer’s specifications
to prevent RF interference.
NOTE : The LCR power cable kit includes a fuse holder
and a 5 Amp fuse to protect the truck system in the event
of a short circuit in the cable. Liquid Controls
recommends that this fuse be used in all installations
not having a fused accessory block to protect the truck
in the event of cable faults. A 5 Amp fuse is required.
