• When using a relay contact output type, externally use a relay according to the capacity of the load to
protect the built-in relay contact.
• When wiring, keep input wires (thermocouple, RTD, etc.) away from AC sources or load wires to avoid
external interference.
3. Operation and maintenance precautions
Caution
• It is recommended that auto-tuning (AT) be performed on the trial run.
• Do not touch live terminals. This may cause electric shock or problems in operation.
• Turn the power supply to the instrument OFF when retightening the terminal or cleaning.
Working on or touching the terminal with the power switched ON may result in severe injury or death
due to Electric Shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)
• As the display section is vulnerable, do not strike or scratch it with a hard object or press hard on it.

the measured temperatures (input value) do not concur due to differences in sensor
accuracy or dispersion of load capacities. In such a case, the control can be set at the
desired temperature by adjusting the input value of sensors.

9. Auto-reset
Auto-reset is performed to correct the offset at the point at which PV indication is stabilized within the
proportional band during the PD control. Since the corrected value is internally memorized, it is not
necessary to perform the auto-reset again as long as the process is the same. However, when OUT1
proportional band is set to 0 or 0.0, the corrected value is cleared.

10. AT (Auto-tuning)
In order to set each value of P, I, D and ARW automatically, the AT process should be made to fluctuate
to obtain an optimal value. One of 3 types of fluctuation below is automatically selected.
For DC voltage, current input, the AT process will fluctuate around the SV for conditions of [1], [2] and [3] below.
Notice
• Perform the AT during the trial run.
• During the AT, none of the setting items can be set.
• If power failure occurs during the AT, the tuning stops.
• Sometimes the AT process will not fluctuate if AT is performed at or near room temperature.
Therefore AT might not finish normally.
[1] In the case of a large difference between the SV and processing temperature as the
temperature is rising
When AT bias is set to 20 , the AT process will fluctuate at the temperature 20 lower than the SV.

Attached functions:
[Power failure countermeasure]:
The setting data is backed up in the non-volatile IC memory.
[Self-diagnosis]:
The CPU is monitored by a watchdog timer, and if the CPU’s status becomes abnormal, the controller is
switched to warm-up status with all outputs OFF.
[Automatic cold junction temperature compensation] (Only thermocouple input type)
This detects the temperature at the connecting terminal between the thermocouple and the instrument, and
always maintains it at the same status as if the reference junction location temperature was at 0 (32 ).
[Warm-up indication]
After the power supply to the instrument is turned on, the PV display indicates the sensor input type,
and SV display indicates input range high limit value (for thermocouple, RTD) or Scaling high limit
value (for DC input) for approximately 3 seconds.
[Indication range and Control range]
Thermocouple input: [Input range low limit value – 50 (100 )] to [Input range high limit value + 50 (100 )]
RTD input: [Input range low limit value -Input span x 1%] to [Input range high limit value + 50 (100 )]
DC current, voltage input:
[Scaling low limit value -Scaling span x 1%] to [Scaling high limit value +Scaling span x 10%]
[Burnout]
When the thermocouple or RTD input is burnt out, OUT1 and OUT2 are turned OFF (for DC current
output type, OUT1 low limit value) and the PV display flashes “
”.
However, for the manual control, the preset MV (manipulated variable) is outputted.
When the DC current or voltage input is disconnected, PV display flashes “
” for 4 to 20mA DC
and 1 to 5V DC inputs, and “
” for 0 to 1V DC input. For 0 to 20mA DC, 0 to 5V DC and 0 to 10V DC
inputs, the PV display indicates the value corresponding with 0mA or 0V input.
