Silicon rubber is supplied in a tube (100g). If two or more instruments are ordered, you can select a tube of silicon rubber for every 5 units. Select silicon-free grease (B) if the instrument is to be used in an environment where generation of silicon is not desirable such as semiconductor manufacturing facilities. The grease, which is soluble in water, should not be used in an environment where water may be splashed onto it or condensation may occur on the surface of the piping. Since it does not harden, periodic maintenance (cleaning and refilling of approximately once every 6 months in room temperature) is required.

3.3. Flow transmitter wiring

3.3.1. Precautions in wiring

CAUTION

(1) Use a special coaxial cable (FLY3 or FLY4) as a signal cable between the detector (FLS) and flow

transmitter (FLR). Do not provide a junction of the signal cable midway.

(2) Be sure to pass the signal cables through a metal conduit between the detector and flow transmitter.

Upstream and downstream signal cables may be put in the same conduit but, to avoid an interference, do

not put the power cable together. (3) For output signal, use a shield cable, where possible. (4) To avoid ingress of noise, do not put the cables together with heavy duty line or the like into the same

duct. (5) If a ground wire is included in the power cable, connect it to ground as it is. (6) A power switch is not provided on the instrument and must be mounted separately. (7) Hermetically cover unused wiring ports by furnished caps.

3.3.2. Applied wiring

Use the following cables.

Power cable : 3 or 2 core cabtyre cable.

Nominal cross-sectional area 0.75 mm Finish outer diameter ∅11 mm.

Output signal cable : 2 or, as required, multiple core cabtyre cable.

Finish outer diameter ∅11 mm.

Detector-flow transmitter cable : Signal cable by type designation (heat-resisting high-frequency coaxial cable having

50 Ω of characteristics impedance. In case FLSE12 or FLSE22, provided with oneside waterproof BNC connector). Finish outer diameter ∅5 mm.

min.

3.3.3. Treatment of wiring ports

The outer case of flow transmitter is waterproof (IP65). However, if installed in a humid place, the wiring ports must be made airtight to avoid ingress of moisture, condensation, etc. Be sure to use the waterproof glands furnished with the instrument in order to ensure the waterproof means. Hermetically seal unused glands by furnished caps.

CAUTION

Do not install the instrument where there is a risk of inundation.

(1) Provide wire rope for the upstream and the

downstream detectors. Make sure that the length of the wire rope is longer than the circumference of the pipe.

(4) Clean the surface of the pipe, then mount the detector.

Fig. 3-32

(2) Lay the wire rope around the pipe at the position of

the upstream detector. Then hook the mounting spring into the wire rope.

3.8. How to remove the sensor unit (FLSE12, FLSE22)

If the sensor unit has to be detached from the frame such as after mistaking the space between the sensor units, proceed as follows.

(1) Loosen the wind bolt located at the middle of frame

by 3 to 4 turns (Fig. 3-39).

Note 1: Do not loosen the wing bolt completely.

(3) Likewise, disengage the opposite claws of the sensor

unit pressing fixture from the frame (Fig. 3-41).

Wing bolt

Fig. 3-39

(2) By hand, hold the frame near the pressing fixture for

a sensor unit to remove. Press the resin section which stands out of the frame of sensor unit just enough to open the frame a little (about 1 mm). At this time, the claws of sensor unit fixture are disengaged from the frame (Fig. 3-40).

Note 2: Do not open the frame excessively. Otherwise,

it may deform, and an accurate measurement could be impossible or the sensor unit could not be installed.

Fig. 3-41

(4) Making sure claws have been disengaged from both

sides, and pull out the sensor unit from the frame (Fig. 3-42).

(5) In the same procedure, remove the other sensor unit

also.

Note 3: After removing both sensor units, tighten the

loosened wing bolt as before.

4.5.6. Setting the total

4.5.6.1. Setting the total pulse (pulse value, pulse width)

Description

Set for total a process variable (flow rate) by total meter, etc. according to total pulse output.

Pulse value: Total amount (volume) per pulse.

A pulse is outputted when the total volume has attained an amount set by the pulse value, and adds to the total pulse count (in case of total pulse indication). Settable range: 0.000001 to 99999999.

* Set the total unit before setting the pulse value (see Section 4.6.3.).

Pulse width: Width of total pulse output.

Select a pulse width according to a corresponding total meter out of menus. Settable range: 5 ms, 10 ms, 50 ms, 100 ms, 200 ms. Note: If the output is through DO2 (relay contact), select 50 ms or longer (see Section 4.5.7.). Restrictions in the setup

Output of total pulses involves the following restrictions depending on the DO output port (DO1, DO2).

DO output port

DO1: Transistor open collector

DO2: Relay contact 1 pulse per day to 1 pulse per second 50ms, 100ms, 200ms

Furthermore, the maximum output frequency is restricted also by the setup of the pulse width. Therefore, set the pulse width and pulse value so that both of condition 1 and condition 2 indicated below are satisfied. Correct motions may not occur, if any setup that does not satisfy both of condition 1 and condition 2 is made.

Condition 1:

1 FLOW SPAN-1

86400

[Hz]

PULSE VALUE [m

Condition 2:

FLOW SPAN-1

PULSE VALUE [m

Note 1) [m3

]

Note 1: The range of FLOW SPAN-1 or FLOW SPAN-2, whichever is larger, is the object in the case of 2-range setup. Note 2: Restrictions in the maximum output frequency of each output port is also applied when the flow rate exceeds

the set range. Therefore, if such a setup that the maximum frequency occurs at the time of 100% flow rate of the set range is made, there is a possibility where the total pulse output is incapable of following when the flow rate exceeds 100% and accurate total value cannot be obtained if over-range continues for a long time. If there are cases where the flow rate exceeds 100%, therefore, review the range and pulse value so that the maximum frequency will not exceed the restricted level.

Pulse output frequency range (at the time of full scale flow rate)

1 pulse per day to 100 pulses per second

The settable range of the pulse value that satisfies both of condition 1 and condition 2 is as follows from results of calculation A and B:

From condition 1,

4.7.5. How to validate the test mode (simulated flow rate output)

Description

Checks different outputs (LCD indication, analog output, DO

output) upon simulating flow rate outputs. With the output at the

actuated time as an initial value, the output changes up to the input

value (simulated flow rate target value) in a selected tracking time

and, at the input value, the output value becomes constant. Each

output changes with a simulated flow rate output. So long as the

test mode is valid, "T" blinks on the left end of the 1st line of LCD

on the measurement mode screen.

Settable contents

Test mode validation : Validates or invalidates the test mode. Input value : Simulated flow rate target. Tracking time : Time required to attain the simulated flow rate target (above input value).

Settable ranges

Test mode validation : SETTING (valid), NOT USED (invalid). Input value : 0 to ±10 [m/s] in terms of flow velocity. Tracking time : 0 to 999 seconds.

CAUTION

In this mode, the analog output, and DO1 and DO2 outputs change with settings. Check beforehand

whether each output can be changed or not. Be sure to resume "NOT USED" after the end of test. Otherwise, the input value output status will be

held until power is turned off. If the TOTAL MODE is set at "START", the total value also changes. If it is desired not to change the

total value, select "STOP".

CAUTION

Turn off power before opening the flow transmitter cover.

Arresters are connected to each of power terminals (N, L) in standard, and arresters can be connected to

each of output terminals (Iout, DO1, DO2) optionally. Before measuring the insulation resistance between a power terminal and grounding terminal, remove the grounding plate from inside the terminal box as illustrated below. Before measuring the insulation resistance between each of the said output terminals and grounding terminal (GND), remove an arrester board, if provided optionally. The insulation resistance performance is 100 MΩ/500 V DC.

After the end of test, return the grounding plate and arrester board in place.
