Instructions

for

Mounting

the

Flange

with

Pipe

In

the

description that

follows,

the

term

"flange"

is

used

to

refer

to the flange

with

pipe

The

standard

flange

supplied

by

SICK

has a

total length

of 130 mm and an

oute

diameter

of 76 mm.

>

Mount

the flange in

such

a way

that

the

axes

are

aligned.

The

angular dis-

placement must

be

less than

1°.

Suitable reinforcements

or

support

construe

tions must

be

provided

on

thin-walled ducts.

>

The

pipe stubs

on the flange

should protrude into

the

duct

by

approx.

30 mm

The

pipe stubs must also

be

adapted

if

necessary.

^ A suitable auxiliary pipe

can be

used

to

align

the

flange

for

measuring dis-

tances that

are

easily accessible

(up to 2 m).

(The inner diameter

of

standarc

flanges

is

70.2

± 1

mm.)

>

The

optical alignment

aid

(accessory) must

be

used

for

longer measuring

patl

or

measuring paths that

are

difficult

to

access.

3.2.3 Purge-Air

Unit

(Option)

The

three-phase a.c. motor

of the

type

2BH1300

fan is

connected

to the 3 L-

conductors

LI,

L2, and L3. The

rated voltage

of the

motor

in the

running connec-

tion

must

be

equal

to

that

of the

phase-to-phase

voltage

of the

system

(oper-

ating

voltage).

Motors with a winding construction

for 230 V

(A)/400 V (Y)

can be

used

if

they

are

started directly

and if a

suitable circuit

is

provided

on the

terminal board

for

230 V or 400 V.

Zero

Calibration

A

zero calibration must

be

carried

out on the GM 901

before

the

device

is put

into operation

for the

first

time

or

before

it

resumes operation.

A

СО-free environment

is

required

for the

zero calibration.

The

calibration

can

also

be

carried

out

directly

at the

measuring

point

if the

plant

is

shut

down

and

the

duct

is

free

of CO.

If a

zero calibration

is not

possible

at the

measuring point,

it

must

be

carried

out

with

the

transmitter

and

receiver

at the

mounting brackets.

Calculating

the

Test

Values

The

test

concentration (test cell value)

is

calculated using

the

following

formula*:

TV

[ppm

x

m]

= MR

[ppm]

x x x S

[m]

TV = Test value

MR = Upper measurement range limit

x = Position

of the

test

point

S = Measuring distance

Example:

Upper

measuring range limit

MR = 1500

ppm

Measuring distance

S =

4m

Test point

at 70% of MR x= 0.7

TV

[ppm

x m] = MR

[ppm]

x x x S [m]

TV

[ppm

x m] =

1500 [ppm]

x 0.7 x 4 [m]

TV

[ppm

x m] =

4200

[ppm

x m]

The

test

cell value should

be

4200

ppm x m.

The

nearest

test

cell

has the

test

value

4000

ppm x m.

* If the

concentration values

are in

mg/m3,

they

must

be

converted accordingly.
