1. Installation precautions

Caution

This instrument is intended to be used under the following environmental conditions (IEC61010-1): Overvoltage category Mount the controller in a place with:

• A minimum of dust, and an absense of corrosive gasses

• No flammable, expolsive gasses

• No mechanical vibrations or shocks

• No exposure to direct sunlight, an ambient temperature of 0 ... 50°C (32 ... 122°F) that does not change suddenly

• An ambient non-condensing humidity of 35 ... 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 unit

Note: Do not install this instrument near flammable material even though the case of this

instrument is made of flame resisting resin. Avoid setting this instrument directly on flammable material.

2. Wiring precautions

, Pollution degree 2

Caution

• Use the solderless terminal with an insulation sleeve that fits in the M3 screw when wiring the CS4H or CS4L.

• 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 with the terminal screw.

• Tighten the terminal screw within the specified torque. If excessive force is applied to the screw when tightening, the screw or case may be damaged.

• Do not apply a commercial power source to the sensor which is 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)

• When using a 24V AC/DC for the power source, do not confuse the polarity when it is DC.

3. Running and maintenance precautions

Caution

• It is recommended that PID auto-tuning be performed on the trial run.

Do not touch live terminals. This may cause electric shock or problems in operation.

•

• Turn the power supplied to the instrunment OFF when retightening the terminal and

cleaning. Working or touching the terminal with the power switched ON may result in Electric Shock causing severe injury or death.

• Use a soft, dry cloth when cleaning the instrument.

(If paint thinner is used, it might deform or tarnish the unit.)

• As the display section is vulnerable, do not strike or scratch it with a hard object or press

hard on them

Caution

• Use a thermocouple and compensating lead wire according to the sensor input specifications of this controller.

• Use a 3-wire RTD system according to the sensor input specifications of this controller.

• This controller has no built-in power switch or fuse. It is necessary to install them in the circuit

near the external controller.

(Recommended fuse: Time-lag fuse, rated voltage AC 250V, rated current 2A)

• When using a AC/DC 24V for the power source, do not confuse the polarity when it is DC.

• When using a relay contact output type, 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.

• Use a thick wire (1.25 … 2.0 mm

) for the earth ground.

[Sensor correction function]

This corrects the input value from the sensor. When a sensor cannot be set at a location where control is desired, the sensor measuring temperature may deviate from the temperature in the controlled location. When controlling with plural controllers, sometimes the temperatures measured (input value) do not concur with the same setting value due to difference 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. However, it is effective within the input rating range regardless of the sensor correction value.

[Loop break alarm]

The alarm will be activated when the process variable (PV) does not rise as much as the span or greater within the time it takes to assess the loop break alarm after the manipulated variable has reached 100 % or the output high limit value. The alarm will also be activated when the process variable (PV) does not fall as much value as the span or greater within the time it takes to assess loop break alarm after the manipulated variable has reached 0 % or the output low limit value. When the control action is Direct (Cooling), read “fall” for “rise” and vice versa.

[Energized/Deenergized]

When alarm action energized is selected, the alarm output (between terminals 7-8, or 12-13) is conducted (ON) while the alarm output indicator is lit. The alarm output is not conducted (OFF) while the alarm output indicator is not lit. See (Fig. 5.5-1).

When alarm action deenergized is selected, the alarm output (between terminals 7-8, or 12-13) is not conducted (OFF) while the alarm output indicator is lit. The alarm output is conducted (ON) while the alarm output indicator is not lit. See (Fig. 5.5-2).

8. Control action explanations

8.1 PID

(1) Proportional band (P)

Proportional action is the action which the control output varies in proportion to the deviation between

the setting value and the processing temperature.

If the proportional band is narrowed, even if the output changes by a slight variation of the processing

temperature, 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 processing temperature, control action changes to ON/OFF action and the so called hunting phenomenon occurs.

Therefore, when the processing temperature comes to the balanced position near the setting value 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, the returning speed to the

setting point is accelerated. However, the cycle of oscillation is also accelerated and the control becomes unstable.

(3) Derivative time (D)

Derivative action is used to restore the change in the processing temperature 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 made

longer, an excessive returning phenomenon may occur and the control system may be oscillated.

8.3 Auto-reset (offset correction)

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