2. Introduction
2-1. Preliminary check
The controller has undergone sufcient quality control inspections, but you should check the specication code, inspect the
controller and make sure you have all the accessories to make sure nothing is missing or damaged.
Compare the specication code on the case with the following to make sure it is the product you ordered.
2-1-1. Specication code check
Item Code Specications
1. Series AR18 - DIN 96 x 96 digital controller
2. Measured values 1Equipped with indicator (red) 4 digits Character size 14.3 mm
0Not equipped with indicator
3. Input □□□ See Measuring Range Codes.
4. Control mode
1One setting, two-position type DF: 0.1 – 9.9% FS (Control output 2 cannot be selected)
2Two setting, two-position type DF: 0.1 – 9.9% FS (alarm output cannot be selected)
3 Three-position type DF: 0.2% FS DB: 1 – 99% FS (Control output is Y–N xed)
5. Control output 1
To select three-position, select “Y.”
Y - Contact 1c 240 V AC 5A / resistive load 2A / inductive load
P - SSR drive voltage output / 12 V±1.5 V DC (max. load current 30 mA) *1
6. Control output 2
To select one-setting, two-position type, select “N.”
To select two-setting, two-position type, select “Y” or “P.”
To select three-position type, select “N.”

2-2. Notes on use
Do not operate the front panel keys with hard or pointed objects. Always press the keys lightly with the tips of your ngers.
To clean, wipe lightly with a dry cloth. Do not use solvents such as thinner.
*1: For SSR drive voltage output,
“heating action only.”
*2: Specication for lower limit value/
higher limit value within measuring
range is possible (specify when
ordering).
