For a safe use of the LQ500 Density Meter, take precautions described in this manual and

observe ordinances in making the installation and operation. Toshiba is not responsible for any

accident arising from the use that does not conform to above.

INSTALLATION PRECAUTIONS

WARNING

■Electrical work, installation

work are needed for the meter.

Please consult with the sales

agent youpurchased the meter,

some of the companies

specialized in this field or your

Toshiba representative.

If any of these work items is

performed incorrectly, this can

cause fire or explosion.

■The meter is heavy. To move

the meter for relocation or

installation, a qualified operator

must handle it by using

equipment such as a truck, a

crane or a sling.

In addition, when you lift the

meter with its lifting bolts, make

sure the bolts have been

securely tightened to the end.

Overturning or dropping can cause

injuries or equipment failure.

DON’T

■Do not operate where there is

a possibility of leakage of

flammable or explosive gas.

A fire or explosion can occur.

CAUTION

■Avoid installing the meter in

any of the following places:

Otherwise, a fire or equipment

breakdown or failure can occur.

lDusty place

lPlace where corrosive gases

(SO2, H2S) or flammable gases

may be generated.

lPlace exposed to strong vibration

or shock.

lPlace exposed to condensation

due to abrupt change in

temperature.

lPlace too cold or hot for

installation

lNear an apparatus that generates

strong radio waves or strong

magnetic field.

■Install the meter in a place

easier for operation,

maintenance and inspection.

In addition, when you place the

meter temporarily in a stocking

area, make sure to execute fall

prevention measures.

Stumbling over the meter or a fall of

the meter can cause injury.

WIRING PRECAUTIONS

WARNING

■Be sure to install a fuse and a

switch to disconnect the

equipment from the power

source.

Failure to observe this can cause

electric shock or equipment failure.

■Be sure to ground the

equipment using a grounding

wire separate from those used

for power tools.

(Grounding resistance: 100 Ωor

less)

Without grounding, electric shock,

malfunction, or equipment failure

can be caused by electric

leakage.

■Make sure that the main

power line is off before wiring or

cabling.

Wiring or cabling without switching

off the main power line can cause

electric shock.

■Use crimp terminals with

insulation sleeves for power

line and grounding wire

terminals.

A disconnected cable or wire from

the terminal or a loose terminal

can cause electric shock or

generate heat and cause a fire or

equipment failure.

■Wiring and cabling should be

done as shown in the wiring and

connection diagrams.

Wrong wiring or cabling can cause

malfunctions, overheating, sparking,

or electric shock.

DON’T

■Do not wireor cable with wet

hands.

A wet hand can cause electric

shock.

The label shown left appears near a terminal block on

the equipment to which power is supplied. Take

precautions to avoid electric shock.

PRECAUTIONS REGARDING MAINTENANCE, INSPECTION,

AND PARTS REPLACEMENT

WARNING

■Be sure to set the power

switch on the equipment to the

OFF position before doing

maintenance or inspection

inside the equipment or

replacing its parts.

Failure to observe this can cause

electric shock or equipment failure.

■Be sure to set the power

switch on the equipment to the

OFF position before replacing

the fuse.

Failure to observe this can cause

electric shock.

DON’T

■Do not touch the terminal

block during maintenance or

inspection. If it is necessary to

touch the terminal block, set the

power switch on the equipment

to the OFF position in advance.

Failure to observe this can cause

electric shock.

DON’T

■Do not attempt disassemble

or modify the equipment.

Failure to observe this can cause

electric shock or equipment

failure.

DON’T

■Do not touch the detector

pipe when high temperature

liquid is flowing in the detector

pipe. The detector pipe also

gets hot from the flowing liquid.

Otherwise, a burn can result.

cable and other sources of noise.

Noise can interrupt correct measurement.

[NOTE] Perform periodic maintenance and inspection.

A long period of reliable measurement requires periodic span calibration

[NOTE] Becarefulnottoletwaterormoistureintotheapplicatormount of the detector,

converter, or cable ends.

Water or moisture can adversely affect performance and shorten parts service life.

Close the covers and doors securely, and make the cable outlets airtight.

[NOTE] Turn on power when the meter is installed on metal pipe.
