Handling Precautions
To obtain the optimum performance from the LF600F and LF602F converter for years of
continuous operation, observe the following precautions.
(1) Do not store or install the flowmeter in:
e places where there is direct sunlight.
e places where there is snow and ice
Infrared switches may not function correctly.
e places where excessive vibration or mechanical shock occurs.
e places where high temperature or high humidity conditions obtain.
e places where corrosive atmospheres obtain.
e places submerged under water.
e 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.
o 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 contro! 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. |
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 100 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 1/2-14NPT 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 6,F8A0869
Handling Precautions (continued)
(5) Ifthe 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.
e 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.
(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:
e Close a transmitter cover before using a transceiver.
e Do not use a transceiver whose output power is more than S W.
e 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.
Class I , Division 2, Groups À, B, C and D,
Class II, Division 2, Groups E, F and G
Class IH
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.
Features
With a linear relationship between the flow rate and output signal, the electromagnetic flowmeter
is featured as an easy-to-read indicator. In addition to this feature, it has the following outstanding

Places within the immediate proximity of equipment producing electrical interference (such as
motors, transformers, radio transmitters, electrolytic cells, or other equipment causing
electromagnetic or electrostatic interference).
Places where there is direct sunlight.
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 of too great an elevation or constricted areas where clearance for installation or
maintenance work is not provided.
The standard length of the cable that connects the detector and converter is 30m. Select the
converter installation location so that the distance of the detector and converter will not exceed
30m.
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
panel.
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.

Notes on wiring
/\ CAUTION
(1) Select the cable runs away from electrical equipment (motors, transformers, or radio
transmitters) which causes electromagnetic or electrostatic interference.
(2) Deterioration of flowmeter circuit insulation occurs if the converter interior or cable ends get
wet or humidified. This in turn causes malfunction of flowmeter or noise problems. Avoid a
rainy day if the flowmeter is to be installed outdoors. Even indoors, prevent water from
splashing over the flowmeter. Try to finish the wiring as quickly as possible
(3) The converter has an arrestor installed inside. Therefore, do not conduct a withstand voltage
test for the converter. To check the insulation of the converter, use a voltage of 250Vdc or
less.
(4) After wiring, be sure to install the terminal block protection cover.
(5) Because the excitation cable and flow rate signal cable transmit very delicate signals, pass each
U of them separately through a thick steel conduit tube, keep them away from the large current

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.
01) 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.

6.1 Preparatory check
Follow the procedure described below to prepare before starting the flow measurement
(described with regard to the entire flowmeter).
System Check
Check the items listed below
Check the wiring between the converter and related instruments.
Make sure all the bolts of connection flanges on which the flowmeter is mounted
securely tightened.
Make sure the direction of flow arrow is in accordance with actual flow.
Make sure the flowmeter is grounded with 100 ohm or less ground resistance.
Make sure the converter housing covers are securely tightened.
Placing System On-Stream
Let the fluid go through the detector pipe. (Note 1)
When the detector is filled with the fluid, stop the fluid and keep it still in the detector pipe.
Supplying Electric Power
Make sure the power supply is as specified.
Checking Converter Parameters
Check the configuration parameter settings. Refer to Chapter 7, “LCD Display and
Controls,” Chapter 8, “Configuration Parameter Setting,” and Chapter 11,
“Communications Function.”
Zero Adjustment
Wait for 30 minutes to warm up the flowmeter. Then making sure the fluid holds still in the
detector pipe, starts the zero adjustment.
Refer to 6.2, “Zero Adjustment.”
On-line measurement
After checking the items and conducting the zero adjustment as listed above, let the fluid go
through the detector pipe. Output (4-20 mA dc) directly proportional to the flow rate can be
obtained.
Note 1: If the detector pipe is not filled with the fluid to be measured, the flow rate will be
indefinite and unable to be measured. Before using the flowmeter , be sure to fill the detector
pipe the fluid to be measured.
TOSHIBA 6F8A08639
6.2 Zero Adjustment
To conduct zero adjustment of the flowmeter, the fluid in the detector pipe must be held still.
There are three different ways to start the zero adjustment:
(1) Pressing a combination of control keys for the model with LCD display
See 8.2.19 “Still Water Zero Adjustment”
(2) Sending a command signal from a HART communications device (a communication
device such as hand-held terminal AF900 is required)

Instructions
The operation principle of infrared switch is to irradiate infrared to the front of control panel and
detect the reflection from finger when operating.
Normal operation is impeded depending on the conditions such as disturbing light from surroundings
or stain attached to the control panel. When unable to avoid such condition, operate the EMF
converter in the following manner.
Remove the factor to impede proper operation of infrared switch as below:
* Cover the control panel by hand so that light does not shine on it
* Clean the stain attached on the control panel
* Clean the stain on the finger or the gloves to operate the EMF converter, or wear gloves in light color
- When there is a reflecting object placed opposing to the control panel, stand in-between the reflecting
object and the control panel to block the light
Following are considered as the 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
* Operation of the control panel by hands wearing gloves in dark color or stained fingers and gloves
* Light reflecting object near the contro! panel, or reflecting object such as metal plate placed opposing
to the control panel

7.3 Basic operations
7.3.1 Mode Change
The converter provides the setting mode and calibration mode, in addition to the measurement mode.
When you want to move to the setting mode or calibration mode, use the "SET" key. To return to the
measurement mode, select "MEAS MODE" from menu items (A to N).
Measurement mode:
measures the process flow and displays and outputs the measured process values. The
flowmeter can measure the flow velocity, flow rates, or totalized flow. The flowmeter first goes
into this mode when power is turned on.
Setting mode:
used to check or change various configuration parameters used in the measurement mode.
These parameter values are displayed while checking or changing these values but the flowmeter
outputs the measured process values as in the measurement mode. See 7.4, “Configuration Items
Selection Table” and 8.2, “Checking or Changing Parameters” for details.
Configuration items are from Al, A2, A3 to M1.
Calibration mode:
used to check the converter internal circuits. The internally generated simulation signal is used
to check the measuring span and excitation current value. The current output of the
flowmeter changes in accordance with the simulation signal. The status of each digital output is
held to the value just before the system moved into the calibration mode.
See 7.4, “Configuration Items Selection Table” and Chapter 9, “Calibration” for details.
Configuration items are from N1 to N4.

OMode switching
The electromagnetic flowmeter usually operates in the measurement mode.
When you need to perform parameter setting, calibration and adjustment, you enter the setting mode.
To enter the setting mode, hold down center key for 3 seconds or longer.
Holding down the desired key for 3 seconds or longer will display screen of code input. When "111"
was input with this screen, [SET] and [CNT] (for switch operation) are displayed in the measurement
screen. When the code except "111" was input, label is not displayed.
Please operate it as follows after label was displayed.
[SET] key You enter the setting mode (the menu configuration setting screen is displayed).

8.2.4 Exciting Frequency
You can select an exciting frequency of 6Hz, 12Hz or 24Hz.
Since each exciting frequency value has its own characteristics, you should select an appropriate
exciting frequency (24Hz is set at shipment. Depending on the characteristics of the detector, a
large frequency may result in excitation failure. When a large frequency value is set and it changes
the indicator value, decrease the frequency to a value that will not change the indicator value.)
