Pulse Output Device (Pod); Differential Pressure (∆P) Transducer - Liquid Controls LectroCount LCR-II E3657 Series Installation Manual

Pulse ouTPuT devICe (Pod)

Pulse output device (Pod)
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 shielded twisted pair of 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.

Transducer Installation
When ordered as part of a meter system with a LCR-II,
Liquid Control's ∆P transducer is wired to the LCR-II
MH4
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

J7 J7
transducer to the LCR-II are provided on this page.
The ∆P Transducer requires an additional board (PN
PULSE INPUTS
81944) that mounts directly to the LCR-II CPU board.
Typically, a ∆P transducer operates in conjuction with a
J12

shutdown device, such as a valve or a dead-man. The

shutdown control must be wired to the LCR-II and should

MH5
SOL To wire ∆P Transducer to the lCr-ii:
1. Unplug the J1 and J3 terminal blocks from the LCR-II
CPU board.
2. Remove the screw at the top left corner of the LCR-II
CPU board.
3. Plug the 81944 board into the J1 connectors on the LCR-
II CPU board.
4. Fasten the top left side of both boards to the housing with
the screw provided.
5. Plug J3 back into its orignal place on the LCR-II CPU
board.
6. Plug the J16 terminal block into the 81944 board.
7. Remove the wires for the J1 terminal block and connect
MH4
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
J6 • 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-II. 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-II.
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.
