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.
