  • Page 5: Application

    1. appLICaTIOn Controller rE01 is designed to control temperature. It cooperates directly with resistance-type sensors pt100, pt1000 and nTC. The controller has one output for on-off control and one output for alarm signalling. The on-off control employs the pID or on-off algorithm. For the on-off control, the minimum on and off times for the output may be set.

  • Page 6: Assembly

    3. BaSIC rEQUIrEMEnTS, OpEraTIOnaL SaFETY In the safety service scope, the controller meets to requirements of the En 61010-1 standard. Observations Concerning the Operational Safety: • The assembly and installation of electrical connections shall be performed by a person qualifi ed for the assembly of electrical devices. • Check if the connections are made correctly before powering on the controller.
  • Page 7 Fig. 1. Attaching the controller The controller’s dimensions are shown on Fig. 2. Fig. 2. Controller dimensions.

  • Page 8: Electrical Connections

    4.2. Electrical Connections The controller has two disconnectable strips with screw terminals. One strip allows for the connection of power supply and output with a wire up to 2.5 mm in size and the other strip for the connection of input signals with a wire up to 1.5 mm in size.

    7. COnTrOLLEr InpUTS anD OUTpUTS 7.1. Measuring Input The measurement input is a source of the measured value used in the control or for the alarm. Depending on the design, pt100, pt1000 or nTC sensors may be connected to the input. First, use the parameter unit to set the displayed temperature unit.

  • Page 22: Control

    8. COnTrOL In the controller you may choose the on-off control or proportional con- trol (pID). For both algorithms you may choose either heating or cooling operation. 8.1. On-off algorithm When the high accuracy of temperature control is not required, especially for objects with a high time constant and low delay, we may employ on-off control with hysteresis.

  • Page 23: Pulse Repetition Period

    8.2.1. Pulse repetition period The pulse repetition period is the time between the subsequ- ent times when the input is enabled during proportional control. Select the duration of the pulse repetition period depending on the dynamic characteristics of the object and as appropriate for the output device. The relay output is used to control the object in slow-changing proces- ses.
  • Page 24 The lit symbol indicated the active self-tuning function. The self-tuning duration depends on the dynamic characteristics of the object and may take up to 10 hours. During or immediately after self-tuning, overshoots may appear, thus a lower set point should be set if possible.
  • Page 25 The self-tuning process will be interrupted and pID set- tings will not be calculated if there is a loss of power to the controller, is pressed or if there is the error eS01 eS02 In such a case the control is started with the current pID settings. If a self-tuning experiment fails, an error code will appear acc.

  • Page 28 The set point for absolute alarms is the measured value determined by the parameter a1sp, (a2sp) and for relative alarms is the control deviation (Sp – pV) from the set point - the parameter a1du, (a2du). The alarm hysteresis, i.e. the area around the set point in which the output status is not changed, is determined by the parameter a1Hy, (a2Hy).

  • Page 30 10.3 Defrost The controller is equipped with a defrost function. This fun- ction only works when the dir type control (cooling) is switched on. The defrost function can be enabled by setting defr parameter to Auto or hand or by short-circuit of the contacts at the binary input (when bNin = defr) regardless of the value of defr parameter.
  • Page 31 10.3.2 Conditions for terminating the defrosting process: If Dmod parameter is set to temp - pV measured value must reach the temperature set by Dsp parame- ter or the defrost time must expire - Dtim parameter. If Dmod parameter is set to time - the defrost time must expire - Dtim parameter.

  • Page 32: Factory Settings

    The defrosting process ends when the conditions for terminating the defrosting process are met, regardless of the state of the binary input. Subsequent activation of the defrosting process via the binary input is possible after re-opening and shorting of contacts at the binary input (reaction to the edge) If defr parameter is set to auto, after defrosting, the subsequent defrosting processes are carried out cyclically according to the time set...

  • Page 33: Programming Interface

    11. PROGRAMMING INTERFACE 11.1. Introduction The controller RE01 has a serial interface for confi guration by means of the programmer pD14. The MODBUS communication protocol is implemented in the interface. The interface is used only to confi gure the controller before you start to use it. You may do it with the free software available at www.lumel.com.pl.
