Philosophy of TeLC Miniplants:

TeLC Miniplants follow a standardized design principle which adopts to some extent the real situation in an industrial plant.So is found the field department and the control department. Field and control are both equipped with original industrial instruments. The control department contains the mimetic display and the control instruments. Deviating from reality the field which is concentrated in the mimetic display is to be physically connected with the control instruments

may be with pneumatic hoses or electric wiring. So the trainee has got an additional task to solve. This connecting is eased in that way that especially for the wiring needs be taken no care with normal bipolar wiring and polarity. Connecting of pneumatics and electrics feels equal. The standardisation of the TeLC Miniplants goes so far as the dimensions height 1.95m and depth 0.65m are equal. Only width differs between 2.2 and 2.9 m and of course weight. Within the abbreviation naming of the units is indicated the control task and instrumentation so e.g. here FIRCA means: Flow - Indication - Registration - Control - Alarm
Wide range of Training Tasks:
  • identification of the process elements and their connection
  • put in action and calibration of elements
  • connection of the process with the control terminal
  • structurizing and configuration of transmitters and controllers
  • running of the process (start & stop )
  • study and optimize the control performance by adjusting the parameters
Built-up of FIRCA:
  • This Miniplant contains a complex circuitry using pneumatic and electric equipment.
  • The fluid flow (water) can take 2 possible ways:
    • The stronger pump drives the water into the blue pipeline through the magnetic F/I- transmitter , the controlvalve with positioner and linear characteristic, the alarm actuator and a rotameter back into the reservoir.
    • The second pump drives water into the red pipeline through an orifice plate with connected p/p-transmitter and the controlvalve without positioner but with logarithmic characteristic, a rotameter and a handvalve for disturbance back into the reservoir.
  • The flowlines can be run under constant pressure conditions which is regulated by the spill valve.
  • Both pumps can be connected in parallel to pump into the blue line.
  • Corresponding to the pneumatic and electric instrumentation p/I and I/p signal converters are existing in the field.
  • The ratio control is realized with the electronic controler used as master and the pneumatic one as slave.
  • The square root transfer of the pneumatic flow signal is realised with the electric controller.
  • length 2,9 m, weight 195 kg. supply 380 V AC and pressed air.
