2.2 Structural Notice
(1) This instrument has explosionproof and waterproof conguration to be ready for outdoor applications.
When you remove the front cover for parameter setting, wiring or the like, be sure to avoid bite of wiring
cable when you restore the instrument.
(2) The pressure-resistant packing unit attached is a part of the pressure-resistant explosionproof construction.
Do not use any pressure-resistant packing other than attached. The union of the pressure-resistant packing
must be tightened sufciently after completion of wiring.
(3) The packing in the pressure-resistant packing unit shall be selected among three different packings (φ11
provided as standard, φ12, and φ13.5) in accordance with the outer diameter of the nished cable.
2.3 Explosionproof Precautions
CAUTION: The following items are the requirements for conforming to the
explosionproof test for this instrument. When you place this instrument
in service, be sure to keep the following precautions.
(1) The grounding for safety grounding terminal shall be single class A grounding.
(2) Do not change or modify the parts, wiring, etc.
(3) Use heat-resistant cables that withstand 70°C min.
(4) Do not open the front cover till 3 minutes passes after power off.
(5) Perform installation, wiring, etc. in accordance with the following conditions.
• The places where this instrument can be installed are risk class 1 and 2.
• In order to retain the explosionproof capability of this instrument, apply single class A grounding work to
the number 16 (ground) of the external wiring terminal block. (Shunt diode type burrier is built in this
instrument.)

3. GENERAL INFORMATION
3.1 Features
This instrument is an explosionproof type card reader conforming to non-contact IC card (MIFARE card
ISO14443 type A) or contact type magnetic card (JISX6301 model II).
Data entry is available in two ways, using a card reader or a numeric keypad. In addition, entry from the
communication port is displayed on the LCD.
Communication interface is via RS422 (RS485).

4. INSTALLATION
4.1 Installation
<Installation Location> Detail of location is subject to explosionproof guide 2000.
Although this instrument is all-weather type (with a cap for preventing direct sunlight), install this instrument in
a place where the display is not exposed to direct sunlight as much as possible.
CAUTION: Avoid the following places for installing this instrument.
• A place where corrosive gas may occur or a dusty place
• A place where vibration or shock is frequent or where vibration or
shock is always present
• A place where ambient temperature is below -20°C or above 60°C
• A place close to the power circuit or a place severely affected by
inductive interference
• A place the operator faces the sky while using the display or numeric
keypad
Otherwise, malfunction or failure may occur.
4.2 Wiring
4.2.1 Wiring Cables
<Wiring cables>
Detail is subject to explosionproof guide 2000.
(1) For communication cables, use twisted paired, electrostatically shielded, vinyl sheathed control cables (0.75
to 2.0mm2) or equivalent.
(2) For power line, use insulated vinyl sheathed control cables (CVV 0.75 to 2.0mm2) or equivalent.
(3) Using crimp-type terminals at the end of wiring, ensure good electrical connections.
<Wiring Connections>
Use the cable connector specied by OVAL.
WARNING: Before wiring the instrument, make sure that the power source is
disconnected.
Wiring with power on may result in electrical shock.
WARNING: • Avoid using a power supply with large voltage variation.
• Do not install the communication line close to or in parallel with the
power lines or high-voltage lines.
• Connect the end of shielded cable to ground.
• Connect the power lines and communication lines correctly.
Otherwise, the instrument may ruin.

(4) If a key input is present, key input processing is implemented.
(5) If a card input is present, card input processing is implemented.
(6) If a display command is transmitted, a display continues for about 20 seconds and returns to the
display of (2). If other processing occurs before the display is restored, the processing (display) is
implemented by priority.
• Key input processing and card input processing are not carried out in parallel.
If either one processing is in operation, the processing coming later is not accepted.
NOTE * : In case of non-contact type specication, "Touch the card" is displayed.
In case of magnetic specication, "Insert a card" is displayed.

a. If card reading occurs during the standby state, a card input processing occurs.
b. When data is read normally, "Sending" is displayed and data is sent to the host system.
The content of the data transmitted is the area specied by the soft switch.
c. After receiving card data sent normally (ID: 11) from the host system, "Card OK" (upper part of LCD) is
displayed.
Then card release (ID: 12) is received from the host system and standby status is restored. ("Card OK"

request is sent beforehand, "Card error" is displayed and the instrument returns to the Standby state.
e. If card data is sent to the host system in state (3) but communication timeout time is exceeded, retry
of sending the same data occurs three times. Then, if there is no response from the host system,
"Communication error" is displayed and the instrument returns to the standby state.
f. If card input processing is in operation, key input processing does not occur.
