auxiliary outputs
The LCR 600 provides three open drain transistor
auxiliary outputs. These output can serve a variety of
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 600.
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 four 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 600 totalizers.
To select the Auxiliary Output settings, refer to the
LectroCount LCR 600 Setup and Operation manual.
auxiliary outputs 4 & 5
(lectroCount remote display)
Auxiliary outputs 4 & 5 are typically used for the
LectroCount Remote Display, but they can also be used
for other types of displays. Signals from these outputs
duplicate the volume data sent to the LCR 600 display.
Refer to the LectroCount remote display manual for
complete installation instructions.
To wire an external display to the lCr 600:
1. Attach cable glands and/or conduit connectors to the
display and the LCR 600 port(s).
2. Thread the wires through a piece of weatherproof conduit
cut-to-length from the display port to a LCR 600 port, 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 600 CPU board.

• Remote display terminal 21 to LCR 600 terminal 39
• Remote display terminal 22 to LCR 600 terminal 40
• Remote display terminal 23 to LCR 600 terminal 41
Disconnect the power before working on the CPU board.
