Decimal input

The cathode side of the LED is out as
an external terminal, so when connected
to GND, the decimal point lights up.

Latch input

When controlled using the latch, the state is
H (data held) or L (data read).
To control without using the latch, connect
to GND.
Be sure to use either control method.
With no connection, the display will notappear or change.

3. Warranty(1) The warranty period for Sunmulon products shall be 1 year after purchase or delivery to the specified location.
(2) Warranty scope should a failure occur in Sunmulon product during the above warranty period for reasons attributable to Sunmulon, then Sunmulon shallprovide that product, free of charge, the same quantity. Further, in no event shall liability of Sunmulon exceed the individual price of the product onwhich liability is asserted.
(3) Failures cause by the following reasons shall be deemed outside the scope of this warranty.
(a) The product was handled or used deviating from conditions / environment listed in the catalogs(b) The failure was caused by reasons other than Sunmulon product(c) Modification or repair was performed by a party other than Sunmulon(d) Replacement of maintenance parts, installation of accessories, or the like was not performed properly in accordance with the user’s manual andcatalogs(e) The failure could not have been predicted with the scientific and technical standards at the time when the product was shipped from Sunmulon(f) The failure was due to other causes not attributable to Sunmulon (including cases of force majeure such as natural disasters and other disasters)(4) The warranty listed in this Safety Precautions is the full and complete warranty for Sunmulon products, and Sunmulon shall bear no liability whatsoever
regarding special damages, indirect damages, incidental damages, or passive damages that occurred due to Sunmulon product.

4. Handling precautions for 7-Segment display(1) Note that if the storage temperature range is exceeded, the product may not operate properly even if it is returned to within the specified operating
temperature range.
(2) Note that the LSI used internally may be destroyed by the floating or latch-up if each signal is input before the VDD is stabilized.
(3) The power input and control signal sections are not equipped with protection circuits, so do not apply electrical stress such as power supply fluctuations(ripple currents and voltages), lightning surges, and noise reverse voltages.
If the element is damaged, it may cause smoke, fire, or burnout. Be sure to use with a protection circuit.
(4) Wire the terminals with correct polarity. Connecting connectors backwards may cause a power short, resulting in burnout.
(5) Turn off the power to the product before starting installation, removal, wiring, maintenance, or inspection. Failure to turn power off may cause
electrical shock or fire.
(6) Be careful of electrostatic breakdown when handling.

Sunmulon Co., Ltd.

PRECAUTION-1

Safety Precautions for All 7-Segment Displays(7) Do not drop or otherwise apply strong force to the 7-Segment display.
(8) Do not place heavy objects on the switch.
(9) The product should be mounted on a solid surface.
(10) Do not use the switch under loads that exceed the rated switching capacity or other contact ratings. Doing so may result in welding of the contact,or burnout accidents.
(11) Assemble correctly according to the handing instructions. Do not assemble or disassemble the product other than as described in the catalog,
as this may cause defects or accidents.
(12) Illumination(a) Do not apply a voltage between the LED terminal that is greater than the rated voltage. Doing so may damage the LED, cause lighting failure.
(b) LEDs cannot be lit directly by AC circuit should be provided rectifier smoothing circuit for products other than AC input type.

(13) Wiring(a) Avoid wiring input lines in parallel with high-voltage lines and power lines, and use ceded wires and metal tubes for noise suppression.
(b) When tighting terminals or connecting connectors, do not apply more force than necessary form the back side.
Support the 7-Segment display with one hand as it may slip out of the front of the panel.
(c) Use the applicable connectors listed in the catalog for each model.

(14) Terminology explained(a) With or without Photocoupler The interface with the user side is isolated by specifying with photocoupler to prevent malfunction from noise.
It is especially effective for long-distance transmission, which is vulnerable to noise. (AD series)(b) Positive logic, Negative logic Applies to BCD code entry only. The input circuit is pulled up. When the user side indicates 0 on input
with an open collector output circuit, a positive logic turns on all transistors for inputs A to D.
Negative logic turns off all transistors for inputs A to D.
(c) Decoder driver This circuit converts the input of BCD code into a signal to drive 7-Segment LED.
(d) Data latch
The 4 bits of data from A to D must be in the holding sate. If LE is set to H (or open), the display will not change even if data
comes in later.
(e) Data through The 4 bits of data from A to D must be in the read state. When LE is set to L (GND), the display changes as the data input changes.

(15) Usage environment(a) Do not use in the presence of flammable or explosive gases such as gasoline, thinner, LPG, etc.
(b) Avoid using the product in places where corrosive or silicon gas is generated, high temperature, high humidity, sea breeze or direct sunlight.
(c) Provide appropriate protection when using the product in places where it is exposed to water, oil, metal powder, or dust.
(d) Do not use the product in a place subject to vibration or shock. It may cause malfunction or damage.
(e) When installed in a close grouping or continuously lit, the ambient temperature may exceed the specified value due to heat generation.
Take measures such as ventilation and lowering the operating voltage.
(f) When checking the actual equipment, load conditions and operating environment should be the same as the actual operating conditions.
(g) The ambient temperature for storage is －25℃ to 65 ℃ (No freeze, no condensation).

(16) When wiping off dirt on the exterior of the 7-Segment display and accessories such as side plates, wipe lightly with a soft, dry cloth. Organic solvents
such as thinner, benzene, alcohol, or other acidic chemicals may cause deformation, discoloration, or malfunction.
(17) Store the product away from malignant gases, dust, high temperature and high humidity, and keep it in our packing condition.

(18) Periodic inspection and replacement(a) Although mechanical and electrical durability are listed in the specifications column, deterioration of various parts (deterioration of resins andcorrosion of metal parts) is possible due to the operating environment and method of use. We ask that you implement inspections for Sunmulon
products to prevent accidents from occurring by conducting periodic inspections and replacements.
(19) Service scope
The price of Sunmulon products do not include the cost of services, such as dispatching technicians.
