auxiliary outputs
The LCR-II provides three open drain transistor auxiliary
outputs for different external devices such as pump
controls and additive injectors. The schematic to the right
identifies the J13 terminals where the auxiliary outputs
can be connected to the LCR-II.
Auxiliary Output 1 (Out 1)
This signal has four output settings: Off, On, On During
Delivery, and Monitor Flowrate.
Auxiliary Output 2 (Out 2)
This signal has three output settings: Off, On, On During
Delivery, and Flow Direction.
Pulse Output (Out 3)
This output represents the gross delivery quantity for
uncompensated deliveries or the net delivery quantity
(for compensated deliveries). This output is a real time
50/50 duty cycle representing the least significant digit of
the LCR-II totalizers.
auxiliary outputs 4 & 5
(lectroCount remote display)
Auxiliary ouputs 4 & 5 are typically used for the
LectroCount Remote Display, but they can also be used
with other types of displays. Signals from these outputs
duplicate the volume data sent to the LCR-II display.
Refer to the LectroCount remote display manual for
complete installation instructions.
To wire an external display to the lCr-II:
1. Attach cable glands and/or conduit connectors to the
display and the LCR-II port(s).
2. Thread the wires through a piece of weatherproof conduit
cut-to-length from the display port to a LCR-II port.
3. Run the weatherproof conduit between the display and
the LCR-II housing, pull the wires through the ports, and
tighten the connectors.
4. Connect the four display terminals to four terminals on
the J18 terminal block of the LCR-II CPU board.
• Remote display terminal 20 to LCR-II terminal 45
• Remote display terminal 21 to LCR-II terminal 39
• Remote display terminal 22 to LCR-II terminal 40
• Remote display terminal 23 to LCR-II terminal 41
To select the Auxiliary Output settings, refer to the
LectroCount LCR-II Setup and Operation manual.

Printer Installation (j1 rs-232)
A Liquid Controls meter system with a LCR-II typically
includes an Epson slip printer or roll printer. Installation
is the same for both printers.
LCR-II’s are typically shipped with a black-sheathed data
cable prewired to terminals J1 and J3 on the LCR-II CPU
board.
To install the printer:
1. Find a convenient mounting spot in the truck cab where
drivers can easily operate the printer.
2. Clean the mounting spot and the bottom of the printer
with alcohol for the best stick.
3. Attach the Velcro to the mounting spot and the bottom of
the printer and fasten the printer to the mounting spot.
4. Connect the data cable to the RS-232 data port on the
back of the printer.

For connecting power to the printer see pg. 29.
See instructions on pages 17 for routing the data
cable from the back of the truck to the cab.
To communicate via true RS-232 protocol, the +VP Red wire must
be connected to the J3 terminal block at terminal 47 (not 46).

epson Printer Ground Wire Kit
Installation
Before connecting power to the LCR-II and the Epson
printer, ground the printer to the truck cab floor. Epson
printers sold for truck installations are all grounded in the
same manner.
To ground an epson printer:
1. Remove one of the mounting bolts fastening the printer
mounting brackets to the truck cab floor.
2. Place one end terminal of the ground wire over the
mounting bolt and return the bolt to its original place.
3. At the back of the Epson printer, remove the silver ground
screw marked “FG”.
4. Place the other end terminal of the ground wire over the
ground screw and return the screw to its original place.
5. Check the strap for a good ground connection (see page
13).
The Epson Printer Ground Wire Kit contains an additional ⅜" ring
terminal for printer brackets not purchased from Liquid Controls
