Scanner 2000 Expansion Board

QuickStart Align hole inexpansion board

with stando.

Align pins on back

of expansion board

with black headers.

Part No. 9A-30165026, Rev. 03

The Scanner 2000 Expansion Board expands the

Scanner 2000s input/output to include:

an additional turbine input

a pulse input (3-30 VDC or contact closure)

two analog inputs (1-5 V, 0-5 V, or 4-20 mA)

an analog output (4-20 mA)

InstallationBeore installing the

expansion board,

remove all power rom

the Scanner 2000(battery and external

power). The expansion

board attaches to two

headers positioned

between the two large

terminal blocks on the

main board. Remove

wiring rom the main

board i necessary to

guide the expansion

board into position.

Remove the stando

rom packaging and

press it into the hole

near the center o the

main board until itsnaps into place.

Guide the expansion

board over the stand-

o and align the pins

on the under side

with the headers on

the main board.

When the board is

positioned correctly,

text on both boards

should ace the same

direction.Gently press the

expansion board and

the main board

together until the

expansion board

snaps into place over

the stando.

3.

Restore wiring con-

nections to the main

board, reconnect the

MVT i disconnected,

and make eld wiringconnections to the

expansion board.

Restore power to the

Scanner 2000 and

reboot the Scanner to

allow detection o the

expansion board.

CAUTION: FAILURE TO ALIGN PINS AND HEADERS

CAN DAMAGE THE BOARDS.

Turbine Input 2

The Turbine Input 2

accepts a turbine

fowmeter input signal

generated by a magnetic

pickup. The Scanner

2000 can be congured

to use this signal to

calculate and display

instantaneous fow rates

and accumulated totals.

Another turbine input

(Turbine Input 1) is pro-

vided on the main circuit

board. When the expan-

sion board is installed, a

dierential pressure fow

run and two turbine runs

can be monitored and

logged simultaneously.

Pulse Input

The pulse input provides

an optically isolated

input or high-amplitude

pulse (requency) signals,

which includes signals

rom a turbine meterequipped with a

preamplier or signals

rom a PD meter (via

contact closure).

The Scanner 2000 can

calculate fow rom no

more than two pulse

(requency) inputs ata time. Thereore, a

pulse input can be used

simultaneously with only

one turbine input (main

board or expansion

board).

Inputs/Outputs

All inputs and outputsare confgured with

ModWorX Pro

sotware provided

with each Scanner

2000 microEFM.

Analog Inputs

The analog inputs, which

can be congured or a

1-5 V, 0-5 V or 4-20 mA

signal, can receive read-

ings rom a pressure or

temperature sensor or

use in AGA-7 gas cal-

culations. Alternatively,

they can be used to log

measurements rom any

device with a 1-5 V, 0-5 Vor 4-20 mA output.

Transmitter power is

provided by the Scanner

only when the Scanner is

externally powered. The

output voltage equals

the input voltage less

0.25 VDC, and is limitedto 20 mA.

I a 4-20 mA transmitter

is used, a resistor must

be added to the circuit.

The expansion board

circuit will support a

resistor range o 200 to

300 ohms; 250 ohms is

recommended.

Analog Output

(4-20 mA)

The 4-20 mA linear

current output can be

congured with

ModWorX Pro

sotware to represent

any parameter in the

holding registers. This

output requires a two-

conductor cable to beconnected to an 8 to 30

VDC power supply (volt-

age required is depen-

dent on loop resistance)

and an analog readout

device to be located in

the remote location.

The graph above showsthe minimum voltage

For example, i a power

supply voltage o 24

volts is available to

power the current loop,

the maximum load

resistance would be 800ohms.
