1. Safety precautions
Be sure to read the instruction manual before attempting to install, operate, maintain or inspect the digital controller.
You should become familiar with the controller, safety information and other important matters before attempting to use the
controller.
The labels for safety precautions in instruction manual are divided into “warning”and “caution.”
The symbol indicates a protective conductor terminal. Be sure to provide grounding.
The AR18 Series digital controllers are control instruments designed for industrial use to control temperature, humidity and
other physical amounts. You should either take appropriate safety measures or avoid using for control that could have a
serious effect on human life. The manufacturer shall not be liable for an accident that results if used without taking appropriate
safety measures.
● The digital controller should be used so the terminal elements in the control box, etc., are not touched by human beings.
● Do not remove the controller from its case, or insert your ngers or electric conductors inside the case. Doing so could
result in electric shock accident involving death or serious injury.
If there is danger of damage to any peripheral device or equipment due to failure of the controller, you should take appropriate
safety measures such as mounting a fuse or overheating prevention device. The manufacturer shall not be liable for an
accident that results if used without taking appropriate safety measures.
● Alert mark on controller name plate
An alert mark is printed on the terminal element name plate applied to the controller case.
The mark indicates you could get shocked if you touch the terminal element while conducting electricity.
● Provide a switch or breaker as a means of cutting off power for external power circuit connected to the power terminal
of the controller. Mount a switch or breaker near the controller where the operator can get to it easily and label it as an
electrical breaker for the controller.
Use a switch or breaker that conforms to the requirements of IEC60947.
● Fuses
The controller does not have a built-in fuse. Be sure to mount a fuse on the power circuit connected to the power terminal.
Provide a fuse between the switch or breaker and the controller. Mount on the L side of the power terminal.
Fuse rating/characteristics: 250 V AC, 0.5 A, medium or slow blowing
Use a fuse that conforms to the requirements of IEC60127.
● Voltage/current of load connected to the output terminal and alarm terminal should be within the rating.
Using voltage/current that exceeds the rating could shorten the life of the controller by raising the temperature, and could
result in controller failure. For rating, see “9. Specications.”
Connect equipment that conforms to the requirements of IEC61010 to the output terminal.
●Do not apply voltage/current other than rated input to the input terminal. Doing so could shorten the life of the product or
result in controller failure.
For rating, see “9. Specications.”
If the input is voltage or current, connect equipment that conforms to the requirements of IEC61010 to the input terminal.
Draft holes are provided in the controller for heat to escape from. Do not allow foreign matter such as metal to get into the
holes.
Doing so could result in controller failure or re.
● Do not allow the draft holes to become clogged with dust, etc.
Doing so could shorten the life of the product due to temperature rise or insulation deterioration, and could result in
controller failure or re.
For space between controllers, see “3-3. External dimensions and panel cutout.”
● Repeating endurance tests such as dielectric strength, noise resistance and surge resistance could negatively affect the
controller.
● The user should absolutely not modify or use the controller other than the way it was intended.
CAUTION
WARNING
●It takes 30 minutes to display the correct temperature after applying power to the digital controller. (Therefore, turn the
power on more than 30 minutes prior to the operation.)
●To ensure safety and maintain the functions of this device, do not disassemble this device. If this device must be
disassembled for replacement or repair, contact your dealer.

3-4. Wiring
Take the following precautions when wiring:
Wire in accordance with the terminal layout of section 3-5 and terminal arrangement table of section 3-6. After wiring, check
and make sure the wiring is correct.
Crimp-type terminals t M3.5 screws. Use crimp-type terminals that are no wider than 7mm.
For thermocouple input, use a compensating conductor that matches the type of thermocouple.
For R.T.D. input, resistance for lead wires should be a maximum of 5Ω per wire. All 3 wires should have the same resistance.
Input signal wires must not be accommodated with a high-voltage power circuit in the same conduit or duct.
Using shielded wiring (single point grounding) is effective for static induction noise.
Making input wiring short and twisting at regular intervals is effective for electromagnetic induction noise.
For power supply, use wiring or cable with sectional area of at least 1 mm² that offers the same performance as 600 V vinyl
insulated wiring.
Securely fasten the terminal element screw. Fastening torque: 1.1 N·m (11 kgf·cm)
 If the controller appears to be easily affected by power supply noise, use a noise lter to prevent malfunctioning.
Mount the noise lter on the grounded panel and make the wire connection between the noise lter output and power line
terminals of the controller as short as possible.
Recommended noise lter: TDK RSEL-2003W
● Be sure to turn off power before wiring. Failure to do so could result in electrical shock.
● After wiring, do not touch terminal elements or other charged parts while conducting electricity. Failure to do so could result
in electrical shock.

3-7-1. Input circuit
The input circuit handles weak electrical signals. Wire separate of the motor and operation circuits.
If wiring together cannot be avoided, make a single contact using shielded wire.
1) Thermocouple input
Be sure to wire the thermocouple with thermocouple compensation lead wire.
Arrange for the total resistance of thermocouple and compensation wiring to be at least 100Ω.
- Reference -
Type of thermocouple and color of compensation wiring
T = brown, J = yellow, E = purple, K = blue, S = black, R = black, B = gray
2) R.T.D. input
Use 3-wire type for R.T.D. wiring, and use the same wiring material so the resistance value is
the same.
The resistance value per wire should not exceed 5Ω. If connected along the way, take proper
measures so contact resistance does not increase.

5-2. Hysteresis, dead band (DB)
ON/OFF control setting value for this series is set in advance. When temperature reaches the set value, control output becomes OFF.
When output becomes OFF, temperature goes down, and then it becomes ON again. This action is repeated at a certain position.
Hysteresis is provided for switching output ON/OFF to stabilize action.
Two-position type
With the two-position type, hysteresis (DF) is set to the desired
value within the range of 0.1 – 9.9% FS.
Three-position type
Three-position includes dead band (DB) setting.
The narrower dead band (DB) is, the less amplitude there
is for heating and cooling and discrepancy with set point
is reduced. It is therefore frequently used for heating and
cooling. Set to the optimal value while observing action.
Set dead band (DB) to the desired value within the range
of 1 – 99% FS.
Hysteresis (DF) is xed to 0.2% FS.

5-3. Operation
5-3-1. Setting set points
Set value is set by and keys. Pressing or key makes the rst decimal point ash and changes the value of the set value.
If there is no key input operation for 3 seconds, update operation is nished and the rst decimal point stops ashing.
The values changed by the and keys are applied to operation immediately.
Set value to 30.0 with the key. (First decimal point ashes.)
↓
No key operation for 3 seconds. Setting changed to 30.0 and update operation nished.
(rst decimal point stops ashing)
5-3-2. Display off
When setting is complete, the hysteresis, dead band (DB), alarm higher limit and alarm lower limit displays darken and go off.
The example shows the case where hysteresis is changed from 0.0 to 1.0.
Set value to 1.0 with the key. (First decimal point ashes.)
↓
No key input for 3 seconds (First decimal point goes off.)
↓Setting is changed to 1.0 and update operation is nished.
Display darkens for 5 seconds.

Display goes off.
6. Explanation of functions
6-1. Control output
*Control output characteristics
In the case of contact output, connect either heating or cooling action as given in the following table.
Only heating is applicable in the case of SSR drive voltage output.
Two-position type Three-position type
Action OUT1 OUT2 Action OUT
Heating 11-12 14-15 Heating 11-12
Cooling 11-13 14-16 Cooling 11-15
Heating: Terminal to be shorted if measured value is lower than set value.
Cooling: Terminal to be shorted if measured value is higher than set value.
6-2. Alarm action
Sets alarm action points for deviation of measured values from target set values.
In the case of input measuring range code 005 (K, 0.0 – 800.0°C), for example, to trigger an alarm when measured value is
201.0°C or higher and the target set value (SV) is 200.0°C, the higher limit alarm is set to 1.0°C (unit).
Or to trigger an alarm when measured value is 198.0°C or less when target set value is 200.0°C, the lower limit alarm is set to 2.0°C (unit).
Alarm action point acts in accordance with target set values (SV).
If alarm action is ON, alarm value (orange) and action display (alarm higher limit and alarm lower limit) LED (red) lights.

Standby action is a system whereby, when power is applied,
if measured value is in the alarm range, the device stands by
without giving the alarm, and once it gets out of the alarm
range, the alarm is given when it enters the alarm range
again. Operates by conventional operation after standby
action is canceled.
Analog output is a function output by converting measured
output to DC current signal according to 0 – 100% of
measuring range. Types of analog output include current
output 4 – 20 mA DC, voltage output 0 – 10 V DC or 0 – 10
mV DC.
