SD16A Instruction Manual
1. Introduction
Note
The environmental conditions fall under installation category
II of IEC 60664, and the pollution degree is "2".
1-1. Check before use
2-2. Mounting
Although the instrument passes thorough quality checks before shipment,
when the instrument is delivered, please confirm the type code number,
check the external conditions and the list of accessories to make sure that
there is no apparent damage or discrepancy.
1 Cut a fitting hole by referring to the panel cutout dimensions in section
2-3. The applicable thickness of the panel is 1.0 ~ 4.0mm.
2 Insert the indicator into the hole from the front of the panel, as it has
catching claws to fix it in position.
Confirmation of the type code
Note
As the SD16A is a panel installation type indicator, use it by
mounting on a panel.
Check the type code printed on the label on the packing case with the
following table to confirm that the delivered goods meet your order.

Note 1
The instrument supports full universal input; however please select one of two
codes, as an external receiving resistor (250
Ω
) is supplied for current input. If
no external receiving resistor is required, a code 8 specification product can
be used for current input.

Note 3
When the 08 power supply code (24V AC/DC) is selected, the sensor power
supply cannot be selected.

1-2. Notes for use
•
Avoid operating the front panel keys with hard or sharp objects. Lightly
touch the operating keys with your fingertips for operation.
•
When cleaning, do not use a solvent such as a thinner. Wipe the
instrument with a dry cloth lightly.
2. Installation and wiring
2-1. Installation site (environmental conditions)
CAUTION
Do not install the instrument in such environmental conditions as those
listed below. Otherwise, damage may be caused to the instrument, even
resulting in fire.
•
Flammable or corrosive gas, oil soot or dust that deteriorates the
insulation is generated or abundant.
•
Ambient temperature is below
−
10°C or above 50°C.
•
Ambient humidity is higher than 90% RH, or below dew point.
•
Strong vibrations or impacts are generated or transferred.
•
High-voltage power lines exist in the neighborhood, or induction
interference.
•
Exposure to direct sunlight or dew drops.
•
The elevation is above 2000m.

2-4. Wiring
WARNING
•
When wiring the unit, be sure to cut the power supply OFF, or there
will be a risk of electric shock.
•
Make sure the protective conductor terminal ( ) is grounded.
Otherwise, a serious electric shock may result.
•
After completing the wiring, do not touch the terminals and electrically
charged parts while the power is ON.
•
Make wiring according to the layout in "2-5. Terminal arrangement."
•
Use ring tongue terminals of 7mm or narrower width to meet M3.5
screws.
•
In case of thermocouple input, use a compensation wire with the type
of thermocouple selected. The external resistance should be100
Ω
or
less.
•
In case of R.T.D. input, the resistance value per lead wire should be 5
Ω
or less, and all three wires should have the same resistance value.
•
Avoid arranging the input signal line to pass through the same conduit
or duct with high-voltage power lines.
•
The shield wire (one-point grounding) is effective to eliminate
electrostatic induction noises.
•
An effective way to eliminate the magnetic induction noises is to twist
the input wire in short and equal intervals.
•
For the source power connection, use a wire or cable having a
cross-section of 1mm
2
or larger, and a performance capacity equivalent
to 600V vinyl insulation wire.
•
The grounding wire should have a cross-section of 2mm
2
or larger, and
the grounding work should ensure a ground resistance of 100
Ω
or less.
•
The
symbol expresses the functional earth terminal. Please connect
it to the ground as much as possible to avoid the adverse impact from
noise.
•
Screw the terminal connection securely.

Noise
filter
In case the instruments are affected by the power supply noise, install a
noise filter to avoid operational errors.
Mount the noise filter on the grounded panel and connect the noise
filter output and the power supply terminal of the indicator with the
minimum possible distance.
Make wire with the mini-
mum possible distance
