1.2 How to read the rated label
The rated label is attached to the case.
When Heater burnout alarm is added, CT rated current is written in the bracket (
).
(1) Model number, supply voltage, input type, output type, etc. are entered.
(2) Lot number is entered.
2. Name and functions of the sections
(1) EVT indicator
The red LED lights when Event output [Alarm, Loop break alarm
or Heater burnout alarm (Option)] is ON.
(2) OUT indicator
When OUT (control output) is ON, the green LED lights.
For DC current output type, this flashes corresponding to the
output manipulated variable.
(3) T/R indicator
The yellow LED flashes during serial communication.
(4) AT indicator
The yellow LED flashes while PID auto-tuning is being performed.
(5) PV display
Indicates the PV (input value) with a Red LED.
(6) SV display
Indicates the SV (main set value) with a Green LED.
(7) Increase key
Increases the numeric value.
(8) Decrease key
Decreases the numeric value.
(9) Mode key
Selects the setting mode or registers the set value.
(By pressing the Mode key, the set value can be registered)
(10) Sub mode key
Enters Auxiliary function setting mode 2 in combination with the Mode key.

Notice
When setting the specifications and functions of this controller, connect terminals 1 and 2 for power
source first, then set them referring to “5. Setup” and “8. Operation flowchart” before performing
“3. Mounting to the control panel” and“4. Wiring”.
3. Mounting to the control panel
3.1 Site selection
This instrument is intended to be used under the following environmental conditions
(IEC61010-1): Overvoltage category
, Pollution degree 2
Ensure the mounting location corresponds to the following conditions:
•
A minimum of dust, and an absence of corrosive gases
•
No flammable, explosive gases
•
Few mechanical vibrations or shocks
•
No exposure to direct sunlight, an ambient temperature of 0 to 50
(32 to 122 )
that does not change rapidly
•
An ambient non-condensing humidity of 35 to 85%RH
•
No large capacity electromagnetic switches or cables through which large current is flowing
•
No water, oil or chemicals or where the vapors of these substances can come into direct
contact with the controller
