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.
