  • Page 5: Intended Use

    Intended Use The module is a general-purpose PID controller module. Analog control valves are actuated via 2 passive current outputs. Digital straightway valves are actu- ated via 2 relay contacts. In addition, two relay contacts are provided for limit monitoring or pre-control. The PID 3400X-121 module is intended for operation in locations subject to explosion hazards which require equipment of Group II, device category 2(1), gas/dust.

  • Page 6: Safety Instructions

    • In hazardous locations the device shall only be cleaned with a damp cloth to prevent electrostatic charging. Maintenance The Protos modules cannot be repaired by the user. For inquiries regarding module repair, please contact Knick Elektronische Messgeräte GmbH & Co. KG at www.knick.de.

    Installing the Module CAUTION! Electrostatic discharge (ESD). The modules’ signal inputs are sensitive to electrostatic discharge. Take measures to protect against ESD before inserting the module and wiring the inputs. Note: Strip the insulation from the wires using a suitable tool to prevent dam- age.

  • Page 13: Pid Controller

    PID Controller Short Introduction PID control requires a closed loop. The control loop is made up of individual components which must be in permanent operation. The process variable to be controlled (controlled variable) is continuously measured and compared with the desired value (setpoint). The aim is to keep the controlled variable at the setpoint.
  • Page 14 PID Controller Short Introduction P Controller (Parameter: Controller Gain) The proportional-action component of a P controller transforms the control deviation (error variable) to a proportional controller output (manipulated variable). The range of the manipulated variable is limited. Therefore, also the usable range of the controller input signal (control range) is limited.
  • Page 15 PID Controller Short Introduction I Controller (Parameter: Reset Time) The integral-action component takes account of the rate of change of the manipulated variable, i.e. it forms the time integral of the error variable. Each value of the controlled variable is assigned to a particular rate of change of the manipulated variable.
  • Page 16 PID Controller Short Introduction D Control (Parameter: Derivative) A derivative control alone is completely unsuitable since it only reacts to changes of the error variable, that is, constant errors remain unnoticed. PD Controller This controller adds the proportional change of the input signal and the rate of change of the controlled variable to the resulting manipulated variable.
  • Page 17 PID Controller Short Introduction The maximum overshoot of the PID controller is even smaller than that of the PD controller. Due to its I-action component there is no remaining offset. However, the components (P, I, D) of a PID controller implement a universally applicable, classical controller thanks to the fast reaction of the P component, the regulating capacity of the I component, and the attenuating effect of the D component.

    Linear PID Controller Analog Controller IV1/IV2 Analog Controller IV1/IV2 The following controller characteristics can be defined: • Values are adjusted toward the setpoint. • In the neutral zone (symmetrical to setpoint) no control takes place. • Controller parameters: Controller gain, reset, and derivative. •...

  • Page 19: Pi Controller With Vertices (Analog Controller Iv1/Iv2)

    Nonlinear PI Controller Analog Controller IV1/IV2 PI Controller with Vertices (Analog Controller IV1/IV2) For control of pH neutralization processes, a nonlinear controller (controller with vertices) often provides better results since the control curve can be better adapted to a titration curve. The PID 3400(X)-121 controller module provides an additional nonlinear PI con- troller.

  • Page 22: Digital Controller Kv1/Kv2

    PID Controller Digital Controller KV1/KV2 Pulse Length Controller The pulse length controller is used to operate a valve as an actuator. It switches the contact on for a time that depends on the controller output (Y). The period is constant. A minimum ON time of 0.5 sec is maintained even if the controller output takes corresponding values.

  • Page 24: Parameter Setting

    Parameter Setting CAUTION! Incorrect parameter setting, calibration or adjustment may result in incorrect measurements being recorded. Protos must therefore be commissioned by a system specialist, all its parameters must be set, and it must be fully adjusted. NOTICE! The "function check” (HOLD) mode is active during parameter setting. The behavior of the current outputs depends on the parameter setting, i.e., they may be frozen at the last measurement or set to a fixed value.
