Pulse ouTPuT devICe (Pod)
Pulse output device (Pod)
Installation
When ordered as part of a meter system with a LCR
600, Liquid Control’s Pulse Output Device (POD) is
installed onto the meter and wired to the LCR 600 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 600
are provided on this page.
Materials needed for wiring valves:
not supplied
with the Pod
•
22AWG 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 600:
1. Attach cable glands and/or conduit connectors to the
POD and the LCR 600 port(s).
2. Thread the wires through a piece of weatherproof conduit
cut-to-length from the POD port to a LCR 600 port.
3. Run the weatherproof conduit between the POD and the
LCR 600 housing, pull the wires through the ports, and
tighten the connectors.
4. Connect the four POD terminals to the four terminals on
the J18 terminal block of the LCR 600 CPU board.
• POD terminal 20 to LCR 600 terminal 31
• POD terminal 21 to LCR 600 terminal 34
• POD terminal 22 to LCR 600 terminal 33
• POD terminal 23 to LCR 600 terminal 37
single Channel Pulse Inputs
The LCR 600 is compatible with the many single channel
pulsers and amplifiers, for example, the SP714 pulse
amplifier from Liquid Controls Sponsler. For the LCR 600
to accept a single channel pulse, you will need version
v1.15 (or above) of the SR600 base software and a
jumper.
To a single channel pulse output to the lCr 600
1. Flash the CPU board with version v1.15 (or higher)
SR600 (LCR 600 registers) 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
LCR 600 CPU board.
Schematic on the right shows wiring to a
Sponsler SP714.

DifferenTiAl Pressure (∆P) TrAnsDuCer
The shutdown device should
draw no more than 1A.
Differential Pressure (∆P)
Transducer Installation
When ordered as part of a meter system with a LCR 600,
Liquid Control’s ∆P transducer is wired to the LCR 600
at the factory. The ∆P transducer can also be ordered
separately and installed onto a meter system already in
service. Refer to the ∆P transducer manual for complete
installation instructions. Instructions for wiring the ∆P
transducer to the LCR 600 are provided on this page.
The ∆P Transducer requires an additional board (PN
81944) that mounts directly to the LCR 600 CPU board.
Typically, a ∆P transducer operates in conjuction with a
shutdown device, such as a valve or a dead-man. The
shutdown control must be wired to the LCR 600 and
should draw no more than 1 A.
To wire ∆P Transducer to the lCr 600:
1. Unplug the J1 and J3 terminal blocks from the LCR 600
CPU board.
2. Remove the screw at the top left corner of the LCR 600
CPU board.
3. Plug the 81944 board into the J1 connectors on the LCR
600 CPU board.
4. Fasten the top left side of both boards to the housing with
the screw provided.
5. Plug J3 back into its original place on the LCR 600 CPU
board.
6. Plug the J16 terminal block into the 81944 board.
7. Remove the wires for the J1 terminal block and connect
them to their corresponding terminals on the J16 terminal
block on the 81944 board
• Black to J16 terminal 30
• Blue to J16 terminal 29
• Yellow to J16 terminal 28
• Orange to J16 terminal 27
• Brown to J16 terminal 26
8. Route the ∆P transducer cable through a cable gland in a
port on the back of the LCR 600. Secure the cable gland.
LC recommends running the cable through weatherproof conduit.
9. Connect the four ∆P transducer wires to terminals J3 on
the CPU board and J16 on the 81944 board, and connect
the shield/ground wire to the ground screw inside the
housing.
• Black to J3 terminal 46
• White to J3 terminal 51
• Yellow to J16 terminal 57
• Blue to J16 terminal 58
10. Run the red jumper wire (provided with the ∆P transducer
kit) from the J8 terminal 32 to J16 terminal 59 (+5 V).
11. Route a two wire cable from the shutdown control device
through a cable gland in a port on the back of the LCR
600. Secure the cable gland.
LC recommends running the cable
through weatherproof conduit.
12. Connect the two wires from the shutdown control device to
terminal block J13, terminals 14 and 15.

When removing the
terminal from the 81944
board, hold down the
right end of the main
CPU board to prevent
flexing.
Be Careful with the
CPU Board
The J2 terminal block is permanently
attached to the CPU board.
