Handling Precautions
To obtain the optimum performance from the LF600F and LF602F converter for years
continuous operation, observe the following precautions._______________________________
(1) Do not store or install the flowmeter in:
• places where there is direct sunlight.
• places where there is snow and ice
Infrared switches may not function correctly.
• places where excessive vibration or mechanical shock occurs.
• places where high temperature or high humidity conditions obtain.
• places where corrosive atmospheres obtain.
• places submerged under water.
• place where there is slop floor. To put the flowmeter temporarily on the floor, place it
carefully with something, such as stopper, to support it so that the flowmeter will
not topple over.
• Places where there is following factors.
♦ Factors to impede infrared switch to operate properly
• Intense light such as direct sunlight and reflected sunlight by window glass or metal plate
• Place where brightness changes always such as ON/OFF of lighting
• Dense smoke or steam near the control panel
• Those attached on the control panel such as rain (dew drop), snow, ice, mud and oil, and
haze due to their attachment
• Light reflecting object near the control panel, or reflecting object such as metal plate placed
opposing to the control panel
When any of above factors is considered, take a measure for the proper operation of
infrared switch such as to place a cover or to secure a space for at least a person to stand in
front of the control panel.
of
When unable to avoid above factors, operate the EMF converter removing the factor by
covering the control panel by hand so that light does not shine on it, by cleaning those
attached on the control panel, or by standing in-between the reflecting object and the
control panel to block the light.
(2) Wire cables correctly and securely.
Be sure to ground at the converter side (grounding resistance 100П or less).
Avoid a common ground used with other equipment where earth current may flow. An
independent ground is preferable
(3) Select cable paths away from electrical equipment (motors, transformers, or radio
transmitters), which causes electromagnetic or electrostatic interference.
(4) The cable glands is not provided in the conduit port of this apparatus.
Because I/2-14NPT screw holes are processed to this place, please prepare yourself for the
cable glands which could be used in Division2 hazardous locations.
The cable lead-in section must be tightened securely to keep air tightness.

TOSHIBA
Handling Precautions (continued)
(5) If the inside of the converter or cable terminals are wetted or humidified, it may cause
insulation deterioration, which can result in fault or noise occurrence. So do not conduct
wiring in the open air on rainy days.
Also, be careful not to wet down the converter even in the case of indoor wiring, and
complete wiring work in a short period of time.
(6) Observe the following precautions when you open the converter housing cover:
• Do not open the cover in the open air unprotected against rain or wind. This can
cause electric shock or cause damage to the flowmeter electronics.
• Do not open the cover under high ambient temperature or high humidity
conditions or in corrosive atmospheres. This can cause deterioration of system
accuracy or cause damage to the flowmeter electronics.
(7) Since a varistor is built in converter, do not conduct a withstand voltage test for the
converter.
In addition, the voltage for checking the insulation of the converter must be 250VDC
or lower.
,6,F,8,A0,8|6|9i
(8) This product may cause interference to radio and television sets if they are used near
the installation site. Use metal conduits etc. for cables to prevent this interference.
(9) Radio transmitters such as transceivers or cellular phones may cause interference to the
flowmeter if they are used near the installation site. Observe the following precautions
when using them:
• Close a transmitter cover before using a transceiver.
• Do not use a transceiver whose output power is more than 5 W.
• Move the antenna of a transceiver or a cellular phone at least 50 cm away from the
flowmeter and signal cables when using it.
• Do not use a radio transmitter or a cellular phone near the flowmeter while it is
operating online. The transmitter or cellular phone’s output impulse noise may interfere
with the flowmeter.
• Do not install a radio transmitter antenna near the flowmeter and signal cables.
(10) For reasons of flowmeter failure, inappropriate parameters, unsuitable cable
connections or poor installation conditions, the flowmeter may not operate properly.
To prevent any of these problems causing a system failure, it is recommended that
you have preventive measures designed and installed on the flowmeter signal
receiving side.
(11) For piping and installation of the combined detector, check the model number of
detector and read the instruction manual of the relevant detector.
We assume no responsibility for nonconformity caused by violation of precautions described
in this manual or used in violation of the installation method and the operation method
stipulated in a relevant ordinance or other regulations.

2. Overview
The LF600F and LF602F electromagnetic flowmeter converter can be use in the following
hazardous (classified) locations.
This product is a converter used for electric flowmeters that measure the volumetric flow rate of
conductive fluid using Faraday's law of electromagnetic induction.
You can bring out the functions of the converter when you place it in the converter housing you
prepare and use it in combination with a fluid rate measurement detector.
The converter sends out a signal to drive the detector exciting coil, which generates a magnetic
field inside the detector. The converter receives the signal electromotive force obtained by the
detector, as signal electromotive force in proportion to the generated flow rate in the fluid using
Faraday's law of electromagnetic induction. After carrying out operation, the converter converts
the signal electromotive force to an analog signal instrumentation unified signal output and
displays the status, as a flow rate value.

10. Places where there is following factors.
♦ Factors to impede infrared switch to operate properly
• Intense light such as direct sunlight and reflected sunlight by window glass or metal plate
• Place where brightness changes always such as ON/OFF of lighting
• Dense smoke or steam near the control panel
• Those attached on the control panel such as rain (dew drop), snow, ice, mud and oil, and haze due
to their attachment
• Light reflecting object near the control panel, or reflecting object such as metal plate placed
opposing to the control panel
When any of above factors is considered, take a measure for the proper operation of infrared switch
such as to place a cover or to secure a space for at least a person to stand in front of the control

5.3.1 Notes on Instrumentation-Converter Wiring
• To avoid 2-point grounding, ground the shield of output cable basically at the receiving side.
• Use a grounding wire of IV wire 5.5mm^ or more. The size of the external grounding terminal screws is
M4. Do not share a grounding wire with other instruments where grounding current may flow. (An
independent grounding is preferable.)
• Power cable
When a 3-core cable is used: Ground with the FG terminal.
When a 2-core cable is used: Use an external grounding terminal and make the cable as short as possible.
Note that, for a replacement from the Toshiba electromagnetic flowmeter converter LF220 type, the
cable grounding position differs.

5.3.2 Notes on Wiring of the LF602F Type
• The detector is shipped with a flow rate signal cable and excitation cable. Be sure to use those cables
coming with the detector.
Note: When the cable length exceeds 30m, cables may not be supplied. Check whether the
cable is supplied with the specs.
• The allowable cable length between the detector and converter varies depending on the conductivity of
the operating fluid. Refer to the instruction manual of the combined detector.
• When connecting with the detector, wire the cables in the order of the excitation cable and flow rate
signal cable.
• Because the input cables transmit very delicate signals, pass the excitation cable and input signal cable
separately through a thick steel conduit tube , keep them away from the large current wiring as
far as possible, and do not install them in parallel.
• When replacing the flow rate signal cable and excitation cable, also refer to the instruction manual of the
relevant detector. Order the detector terminal box cover packing from Toshiba or a Toshiba distributor.
