Standard Functions

On/off Control
Control characteristic of ON/OFF action
Simple and Basic Control When process value (PV) is below the set value (SV), PXF turns on the output to energize the heater, and vice versa. In this way, PXF keeps the temperature constant by turning the output on and off based on the SV as a threshold.

PID Control with Auto Tuning

Typical Control Based on PID Theory * Overshoot may occur due to external disturbance.

PID Auto Tuning The controller calculates optimal PID parameters. PXF has 2 types of auto-tuning functions; the standard type (auto-tuning with SV used as reference) and the low SV type (auto-tuning with the value 10% below SV used as reference).

Simple Program Control (Ramp Soak Function)
by heating patterns
PXF automatically changes SV to the preset values at preset times. You can set up to 64 steps and 15 types of operation patterns. For example, when you bake four kinds of bread, you can divide 64 steps into four patterns to set suitable temperature for each bread. Example of 16 steps x 4 patterns step 2 step 3

• By connecting a current transformer (to be prepared separately), electric power consumption of the heater can be displayed. (Electric power is calculated based on the fixed voltage value you set.) • Current transformer (CT) is to be prepared separately (see page 10.) • Current detection range: 1 A to 100 A • Indicates the number of days the controller has been operated and activates alarm output (optional) when it exceeds the setpoint. • Useful for preventive maintenance because it let you know the appropriate time for maintenance work.

Please read the following instructions carefully before operating the Digital Temperature Controller
WARNING
Over-Temperature Protection
Any control system design should take into account that any part of the system has the potential to fail. For temperature control systems, continued heating should be considered the most dangerous condition, and the machine should be designed to automatically stop heating if unregulated due to the failure of the control unit or for any other reason. The following are the most likely causes of unwanted continued heating: 1) Controller failure with heating output constantly on 2) Disengagement of the temperature sensor from the system 3) A short circuit in the thermocouple wiring 4) A valve or switch contact point outside the system is locked to keep the heat switched on. In any application where physical injury or destruction of equipment might occur, we recommend the installation of independent safety equipment, with a separate temperature sensor, to disable the heating circuit in case of overheating. The controller alarm signal is not designed to function as a protective measure in case of controller failure.
Caution on Safety * Before using products in this catalog, be sure to read their instruction manuals in advance.

On/off Control
Control characteristic of ON/OFF action
Simple and Basic Control When process value (PV) is below the set value (SV), PXF turns on the output to energize the heater, and vice versa. In this way, PXF keeps the temperature constant by turning the output on and off based on the SV as a threshold.

PID Control with Auto Tuning

PID Auto Tuning The controller calculates optimal PID parameters. PXF has 2 types of auto-tuning functions; the standard type (auto-tuning with SV used as reference) and the low SV type (auto-tuning with the value 10% below SV used as reference).

by heating patterns
PXF automatically changes SV to the preset values at preset times. You can set up to 64 steps and 15 types of operation patterns. For example, when you bake four kinds of bread, you can divide 64 steps into four patterns to set suitable temperature for each bread. Example of 16 steps x 4 patterns step 2 step 3

• By connecting a current transformer (to be prepared separately), electric power consumption of the heater can be displayed. (Electric power is calculated based on the fixed voltage value you set.) • Current transformer (CT) is to be prepared separately (see page 10.) • Current detection range: 1 A to 100 A • Indicates the number of days the controller has been operated and activates alarm output (optional) when it exceeds the setpoint. • Useful for preventive maintenance because it let you know the appropriate time for maintenance work.

Please read the following instructions carefully before operating the Digital Temperature Controller
WARNING
Over-Temperature Protection
Any control system design should take into account that any part of the system has the potential to fail. For temperature control systems, continued heating should be considered the most dangerous condition, and the machine should be designed to automatically stop heating if unregulated due to the failure of the control unit or for any other reason. The following are the most likely causes of unwanted continued heating: 1) Controller failure with heating output constantly on 2) Disengagement of the temperature sensor from the system 3) A short circuit in the thermocouple wiring 4) A valve or switch contact point outside the system is locked to keep the heat switched on. In any application where physical injury or destruction of equipment might occur, we recommend the installation of independent safety equipment, with a separate temperature sensor, to disable the heating circuit in case of overheating. The controller alarm signal is not designed to function as a protective measure in case of controller failure.
Caution on Safety * Before using products in this catalog, be sure to read their instruction manuals in advance.
