Installation
When ordered as part of a meter system with a LCR-
II, Liquid Control’s Pulse Output Device (POD) is
installed onto the meter and wired to the LCR-II at the
factory. The POD can also be ordered separately and
installed onto meter systems already in service. For
mechanical installation instructions, refer to the POD
manual. Instructions for wiring the POD to the LCR-II are
provided on this page.
Materials needed for wiring valves: not supplied
with the Pod
• 22 AWG stranded wire (4)
• Weatherproof flexible conduit, ½" diameter and ½" NPT
conduit connectors or cable glands
• PTFE tape or pipe sealant
To wire a Pod to the lCr-II:
1. Attach cable glands and/or conduit connectors to the
POD and the LCR-II port(s).
2. Thread the wires through a piece of weatherproof conduit
cut-to-length from the POD port to a LCR-II port.
3. Run the weatherproof conduit between the POD and
the LCR-II housing, pull the wires through the ports, and
tighten the connectors.
4. Connect the four POD terminals to four terminals on the
j18 terminal block of the LCR-II CPU board.
• POD terminal 20 to LCR-II terminal 31
• POD terminal 21 to LCR-II terminal 34
• POD terminal 22 to LCR-II terminal 33
• POD terminal 23 to LCR-II terminal 37
single Channel Pulse Inputs
The LCR-II is compatible with the many single channel
pulsers and amplifiers, for example, the SP714 pulse
amplifier. For the LCR-II to accept a single channel
pulse, you will need version v1.15 (or above) of the
SR260 base software and a jumper.
To a single channel pulse output to the lCr-II
1. Flash the CPU board with version v1.15 (or higher)
SR260 base software.
2. Slide the jumper onto the bottom two pins of j17. The
jumper fits over the pins and under the plastic casing.
3. Wire the single channel pulser to the j8 terminal of the
board. Schematic on the right shows wiring to a Sponsler SP714.
Disconnect the power before working on the CPU board.
