Setting the Sensor Type

Select and set the sensor type (i.e., the Input Type parameter) to the set value that corresponds to

the type of sensor used in the application and the required temperature range.

The parameter is set to 5 (K thermocouple at −200 to 1,300 °C) by default.

* When using the ES1B Infrared Temperature Sensor and an analog input, refer to the E5CN/E5AN/E5EN/E5GN Digital

Temperature Controllers User's Manual, Basic Type (Cat. No. H156).

←If the setting of the Input Type parameter does not agree with the connected sensor,

s.err (S.ERR: Input Error) will flash on the display as shown at the left when the power

supply is turned ON.

Use the procedure on page 1-2 to set the Input Type parameter correctly.

The Temperature Controller models are different for resistance thermometers and thermocouples.

Any value can be set for any model.

The set values (SVs) for the Input Type parameter depend on when the E5□N-series

Temperature Controller was sold.

Check your Temperature Controller and set the correct value.

Using ON/OFF Control

2-1

Using ON/OFF Control

The procedure to use ON/OFF control is given step by step in this section.

The default setting is for reverse operation.

For heating control, select reverse operation. For cooling control, select direct operation.

With ON/OFF control, you can adjust the reset width (called the hysteresis) for heating or cooling

operation. The default setting is 1.0°C.

Heating (Reverse) Operation Cooling (Direct) Operation

When the output turns OFF at the set point, the

temperature will decrease. You can set the

temperature width that determines when the

output will turn ON again.

When the output turns OFF at the set point, the

temperature will increase. You can set the

temperature width that determines when the

output will turn ON again.

Using PID Control

3-1

Using PID Control

The procedure to use PID control is given step by step in this section.

The default setting is for reverse operation.

For heating control, select reverse operation. For cooling control, select direct operation.

You can automatically or manually set the PID constants that are used for PID control.

Adjusting the PID Constants

The suitable values of the PID constants that are used for temperature control depend on the

characteristics of the controlled object.

There are three ways that you can use to set the PID constants. These are described

below.

⇒Use autotuning (AT).

⇒Set the PID constants

manually.

⇒Use self-tuning (ST).

1 Select direct or reverse operation.

2 Adjust the PID constants.

If you can allow the temperature to vary while tuning the PID

constants and you need to calculate the optimum PID constants:

If you know the PID constants in advance:

If you cannot allow the temperature to vary and you need to

automatically estimate the PID constants when the set point is

changed:

With self-tuning, calculation of the PID constants is affected by

changes in the temperature, such as when a heater is turned

ON and OFF. The PID constants will be automatically

calculated and set. If there is an external source that causes

temperature changes (such as a heater turning OFF), use

autotuning or set the PID constants manually.

self-tuning

←st (ST): Indicates the Self-tuning parameter.

←Default setting is on (ON): Enabled.

You cannot set the following parameters while self-tuning is

enabled.

•Adjustment Level: MV Upper Limit, MV Lower Limit, and SP

Ramp Set Value

•Advanced Function Setting Level: SP Ramp Time Unit

* To set these parameters, first set the st (ST) (self-tuning)

parameter in the Initial Setting Level to off (OFF) to

disable self-tuning.
