• The terminal block of this instrument is designed to be wired from the left side.
The lead wire must be inserted from the left side of the terminal, and fastened withthe terminal screw.
• Tighten the terminal screw within the specified torque. If excessive force is applied tothe screw when tightening, the screw or case may be damaged.
• Do not apply a commercial power source to the sensor connected to the input terminal
nor allow the power source to come into contact with the sensor, as the input circuit
may be burnt out.
• This controller has no built-in power switch, circuit breaker or fuse. It is necessary to
install them near the controller.
(Recommended fuse: Time-lag fuse, rated voltage 250V AC, rated current 2A)• For a 24V AC/DC of power source, do not confuse polarity when using a direct
current (DC).

Sensor correction function
This corrects the input value from the sensor. When a sensor cannot be set at theexact location where control is desired, the sensor measured temperature may
deviate from the temperature in the controlled location.
When controlling with plural controllers, sometimes 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 byadjusting the input value of sensors.
However, it is effective within the input rated range regardless of the sensor correction value.

8. Control action explanations
8.1 PID(1) Proportional band (P)Proportional action is the action which the control output varies in proportion to thedeviation between the SV and the PV (process variable).
If the proportional band is narrowed, even if the output changes by a slight variationof the PV (process variable), better control results can be obtained as the offset
decreases.
However, if the proportional band is narrowed too much, even slight disturbances
may cause variation in the PV (process variable), control action changes to ON/OFF
action and the so-called hunting phenomenon occurs.
Therefore, when the PV (process variable) comes to the balanced position near the
SV and a constant temperature is maintained, the most suitable value is selected by
gradually narrowing the proportional band while observing the control results.
(2) Integral time (I)Integral action is used to eliminate offset. When the integral time is shortened, thereturning speed to the setting point is accelerated. However, the cycle of oscillationis also accelerated and the control becomes unstable.
(3) Derivative time (D)Derivative action is used to restore the change in the PV (process variable) according
to the rate of change. It reduces the amplitude of overshoot and undershoot width.
If the derivative time is shortened, restoring value becomes small, and if the derivative
time is extended, an excessive returning phenomenon may occur and the control
system may oscillate.

318.2 PID auto-tuning of this controller
In order to set each value of P, I, D and ARW automatically, the auto-tuning process
should be made to fluctuate to obtain an optimal value.
For DC voltage, current input, the AT process will fluctuate around the SV for conditionsof (A), (B) and (C).
Sometimes the auto-tuning process will not fluctuate if auto-tuning is performedat or near room temperature. Therefore auto-tuning might not finish normally.
(A) In the case of large difference between the SV and PV (process variable)
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.

8.3 Auto-reset (offset correction)
Auto-reset is performed to correct the offset at the point at which PV indication isstabilized within the proportional band during the PD action.
Since the corrected value is internally memorized, it is not necessary to performthe auto-reset again as long as the process is the same.
