What is PID? Application.

PID is an internal algorithm stored in the memory of the control device.It can be regarded as an additional function that improves control and steering because it adapts to the system in which it is installed. Without automatic controllers, all control tasks, man would have to be done manually!

PID regulation

Regulacja PID działa bez zadania histerezy
Fig. Diagram - PID control

PID control is used for accurate temperature control without the task of hysteresis (deviation). The control here is done by pulse actuation of the control output, in this case it is worth using solid-state relays (SSR), which are not sensitive to frequent switching.

For more information, see our blog: What is PID?


Auto-tuning function

Funkcja Auto-tuningu
Fig. Diagram - Auto-tuning function

The controller has an auto-tuning function, which is activated only once after the controller is installed in the machine or furnace. It consists in the fact that the controller selects the PID values by itself in order to maintain the set temperature as optimally and accurately as possible. The PID parameters can also be changed manually. The controller can maintain the temperature on the extruder with an accuracy of 0.1°C.

For more information, see our blog: Selecting PID settings in practice.


Alarms

AX series controllers support two independent alarms AL1/AL2 which can be assigned to relay outputs RLY1/RLY2.If you do not assign an alarm to a relay output, no settings will be possible for that alarm.

High alarm
Example al_h27.JPG
The controller will sound an alarm when the temperature rises to 27°C

al_hight.JPG

Low alarm
Example al_low24.JPG
The controller will sound an alarm when the temperature drops below 24°C


Alarm out of range
Example al_o.JPG
The controller will sound an alarm when the temperature falls below 24°C or rises to 26°C


Out of range alarm
Example
The controller will sound an alarm when the temperature rises above 20°C or falls below 30°C



Alarm holding function ( Standby)

When the standby function is used, the alarm output (ON) set in LOW mode is prevented from being driven from the time the controller is turned on until the set temperature is reached.


Locking the alarm in the LOCK function

When the LOCK output option is selected for an Alarm, it is not cleared even if the limiting conditions of that Alarm cease to exist. To delete an alarm with the LOCK option, hold down the "up arrow" key for 2s. Example: If you set a temperature of 100 C for AL1 and set the option "alarm 1 output LOCK - ON", then when this value is exceeded, AL1 will be triggered which will be sustained despite the temperature drop to, for example, 75 °C.


LBA (Loop break Alarm)

When 0% or 100% of the setpoint is reached in PID mode, timing starts. In addition, thanks to this function, it is possible to detect the failure of the heater or sensor after by monitoring the rate of change of the measured value during the period set in the Loop Break Alarm Time parameter. In addition, it is possible to set the Loop break alarm dead zone (LBA).

If 100% of the setpoint value in PID mode is reached, and the temperature rises above the value declared in the "Loop Break Alarm Temperature" parameter within the time specified by the "Loop Break Alarm Time " parameter, the LBA alarm will be activated. If 0% of the setpoint value in PID mode is reached, and the temperature drops below the value declared in the "Loop Break Alarm Temperature" parameter within the time specified by the "Loop Break Alarm Time " parameter, the LBA alarm will be activated.


Phase Control

The control cycle is coupled to the frequency of the supply voltage. RANDOM ON/OFF SSR relays are recommended for this mode of operation (recommended for inductive loads, where delays resulting from the use of ZERO-CROSSING relays may cause malfunctions).


Timeshare Cycle Control (Default Mode).

The controller controls the relay by cyclically adjusting the driving time during a control cycle specified by the user via the Ct parameter. The most common mode of operation for typically resistive loads ( heating elements or others with low impedance ).
