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.

3.5.4. 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).

3.6.7. Mounting of small detector on pipe
The small type detector is mounted on pipe with a diameter of ø50 to 300 (V method) or ø300 to 600 (Z method) for
measurements.
3.6.7.1. Mounting of detector (SX3-C0) <V method>
Mount the detector using the following procedure.
For mounting, have a ruler, scale, or caliper handy for measurement.
(1) Loosen the retaining knob A (4 places), slide the
detectors to match the mounting dimension, place a
scale on the mounting dimension reference surface C
and adjust the separation distance (dimension). Then
tighten the retaining knobs “A”.
(2) Spread silicone filler over the whole transmitting side
of the detector. Ensure enough silicone is applied
smoothly without bubbles and thoroughly to prevent
air gaps.
Clean the surface of the pipe as required and mount
the detector.
Fig. 3-26
Fig. 3-27
(3) Raise the end of the pipe fitted with the detector, and
attach the yellow ring (on the chain) to the hook.

(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.

3.8. 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.

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 second50ms, 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

Condition 2:

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
