3.3. Flow transmitter wiring

3.3.1. Precautions in wiring

(1) Use a special coaxial cable (SX3C) as a signal cable between the detector (SX3) and flow

transmitter (UXF2). Continuous lengths are required. Signal cables may not be spliced or joined.

(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 shielded cable, where possible.
(4) To avoid noise interference, do not run cables through conduits carrying heavy duty or high voltage

lines.
(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 if required.
(7) Cover unused wiring glands and protect from moisture intrusion.

3.3.2. Applied wiring

Use the following cables.

Power cable : 3 or 2 core cabtyre cable.

z

Nominal cross-sectional area 0.75 mm
Finished outer diameter 11 mm.

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

3.5.4. How to mount the sensor unit

(1) Mount both sensor units spaced at the SPACING value [S= **] (number of graduations on frame) indicated after

setting the piping parameters.

Fig. 3-12

(2) Before mounting the sensor unit into the frame, sufficiently

apply silicone filler (or silicone-free grease
entire transmission surface of the sensor unit, taking care not
to introduce bubbles (Fig. 3-13).

Note) When using silicone-free grease, pay attention to the

fluid temperature range. The fluid temperature range is
shown below.
Silicone rubber: 20 to 100qC
Silicone-free grease: 0 to 60qC
When using silicone-free grease, reapply it on the
transmission surface of the sensor unit approximately
once every 6 months. (Silicone rubber need not be
reapplied.)

(3) Then insert the sensor unit into the frame, align the slit

provided on the pressing fixture of the sensor unit with
graduations located on the frame top surface (see Fig. 3-14),
and press the sensor unit until the fixture claws are engaged
with the frame side square holes. Mount both sensor units
so as to be roughly symmetrical with respect to the frame
(see Fig. 3-15).

Mount the detector using the following procedure:

ULLETIN F-7

(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.

Fig. 3-32

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

the upstream detector. Then hook the mounting
spring onto the wire rope ends.

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

Fig. 3-35

(5) Press the detector against the pipe. Align the center of

the detector using the intersection of the marking
line and the mounting dimension as a guide.

Fig. 3-33

(3) Spread silicone filler over the whole transmitting side

of the detector smoothly without bubbles. Ensure
there are no air gaps or bubbles.

Fig. 3-36

(6) Make sure that the center mark on the detector is

aligned with the marking line. Then, connect the
coaxial cable to the transmitter.

Note) Do not pull the coaxial cable. If it is pulled,

the detector is shifted which results in
incorrect measurements due to poor contact.

3.7. Confirmation of received signal

After connecting the signal line, make sure the red LED on the flow transmitter has turned green. It takes about
10 to 20 seconds until the color changes to green.
The green color indicates the received signal is normal. The red color indicates the received signal is abnormal. If the
LED remains red and does not turn green, examine the
engagement, etc.) and

parameter settings, and check whether the piping is filled with fluid

3.8. How to remove the sensor unit (SX3-A0, SX3-B0)

If the sensor unit has to be detached from the frame such as for changing the spacing between the sensor units, proceed as
follows:

(1) Loosen the wing nut located at the middle of the

frame with 3 to 4 turns (Fig. 3-39).

Note 1: Do not loosen the wing nut completely.

Fig. 3-39

(2) By hand, hold the frame close to the pressing fixture

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

(3) Disengage the opposite claws of the sensor unit

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

Fig. 3-41

(4) Ensure the claws are disengaged from both sides, and

remove the sensor unit from the frame (Fig. 3-42).

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

it may bend, so reinstalling the sensor may be
difficult or the frame may become deformed.

Fig. 3-40

Fig. 3-42

(5) Repeat this procedure for the other sensor.

Note 3: After removing both sensor units, retighten the

loosened wing nut.

3.10. How to calibrate zero

Completely close the valves upstream and downstream of the flow meter before calibrating zero.

Notes

1. If there is no valve or if the fluid flow cannot be stopped, select "CLEAR" when "ZERO ADJUST". In this
case, the zero point may slightly be off and manual zero point cannot be set.

2. If parameters are set at "PROTECTION ON", select "PROTECTION OFF" beforehand.

3. SET ZERO: Saves the current flow status as zero. CLEAR: Sets the calibration value for zero point to "0".

4.5.6. Setting the total

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

Description

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

z

Pulse value: Total amount (volume) per pulse.

z

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.

z

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

z

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

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

Condition 1:

1 FLOW SPAN-1

[Hz]

Condition 2:

FLOW SPAN-1

PULSE VALUE [m

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 will occur when the flow rate exceeds

the set range. If the unit is programmed such that the maximum frequency occurs at 100% of flow rate,
totalizer function pulses may be incapable of following the flow rate's required pulsing action for correct

totalizer indication and process measurement. Solution:

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

Description

Checks different outputs (LCD indication, analog output, DO

z

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

starting at some value, the output will be changed to the new value

which is the new simulated flow rate output. The tracking time sets

the time for which the new value becomes constant - mathcing the

simulated flow rate output that is programmed. So long as the

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

on the measurement mode screen.

Settable contents

Test mode validation : Activates or cancels the test mode.
Input value : Simulated flow rate target value.
Tracking time : Time required to attain the simulated flow rate target 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.

In this mode, the analog output, and DO1 and DO2 outputs are changed. Ensure process measurement

z

conditions permit changes to these outputs.
Be sure to resume "NOT USED" setting after tesing. Otherwise, the input value output status will be

z

held until power is turned off.
If the TOTAL MODE is set at "START", the total value also changes. If total must be maintained during

z

testing with simulating flow rate, set TOTAL MODE to "STOP" in advance.
