Performance features

  • Economical entry level variants
  • Full-value regulation and control

Basic functions:

  • 3-point controller, PID controller, heating and cooling switching hysteresis
  • Control functions with inputs and outputs or for temperature control solutions
  • Front installation, optional: Installation from the rear

Operation:

  • 7-segment display, 2 rows
  • 4 keys
  • 5 LEDs for alarms and further function displays

Control:

  • PID control behaviour. The control behaviour can be adjusted via the feedback parameters.
  • Setting the rate time, reset time (P,I,PI,PD,PID)
  • Setpoint limit
  • Self-optimising for adaptation to the controlled system
    • Self-optimising at start up and up to the setpoint.
    • The algorithm determines the characteristics of the system in a closed control loop and calculates the control parameters (Xp, Tv, Tn) over a wide range and the switching cycle time (C = 0.3 x Tv) of a PD/I controller.
    • After calculation of the feedback parameters, the controller returns the actual value to the current setpoint.
    • Self-optimising stopped: by alarm warning and switching off the controller
      Output ratio limitation
  • The output ratio is output to the digital outputs in the form of a PWM signal.
    • The total duration of an On/Off cycle is determined via the switching cycle time parameter.
    • The value parameters are set separately for heating and cooling (P: switching cycle time heating or cooling).
    • Output ratio limitation is only needed in the event of fixed over-dimensioned power supply to the controlled system. Output ratio limitation is usually set to 100 %. For heating and cooling, output ratio limitation can be programmed to between 0 % and 100 %.
  • Control parameters for heating and cooling are separately adjustable. There can be no overlap of heating and cooling.
  • In "Ready for operation" and "Alarm" operating status the controller outputs are set to zero.

Settings ranges and control precision:

  • Feedback: Xp: 0…100% Tv: 0…200sec Tn: 0…999sec
  • Switching cycle time: 1…240sec
  • Output ratio limitation: 0…100%
  • Setpoint limit: -40…400°C
  • Control precision in steady state (without sensors): ± 0.5 K
  • Resolution in the steady control state (without sensors): ± 0.1 K

Control functions (example for temperature control solution):

  • Heating, cooling, alarm, pump (on/off/empty)
  • Watch-dog: Permanent monitoring of correct software process
  • Temperature warning
  • All data are storage is power failure-proof.
  • Filling/float switch
  • Cooling and switch-off
  • Fill time monitoring
  • Restart lockout
  • Do not heat dead zone
  • Switching cycle times
  • System lock
  • Tool emptying
  • Leak stop (direction of rotation of pump - phase switch - is carried out via relay).
  • Display of error messages
