Description

System

This trainer teaches fault diagnosis and rectification in industrial processes. Faults are introduced by the instructor via switches concealed behind a locked compartment, to which the student does not have access. These switches provide both short circuits and open circuits and can also switch in or out circuit elements to simulate a variety of fault conditions. Additional faults can be inserted into the process through the replacement of working components with faulty ones, e.g. faulty flow switches; faulty relays; faulty solenoid coils and faulty control valve electronic circuit board. The process involves initially filling a header tank with water and then cycling the level between a set upper and lower limit, whilst simultaneously creating a demand from the header tank via two on/off solenoid drain valves into a sump tank. Flow is produced by a pump and controlled by relay operated on/off solenoid valves which control:

  • the inflow of water to the header tank from the sump tank
  • the outflow of water from the header tank to the sump tank

The level of water in the header tank is monitored by float switches which open and close at the following points:

  • Header tank low (nearly empty)
  • Header tank normal operation lower limit
  • Header tank normal operation upper limit
  • Header tank overflow

Designed for students studying industrial process maintenance, it can also be used as a process trainer in its own right, using either Industrial Process Controllers or Programmable Logic Controllers (PLCs). A 34-252-1 PLC Board (supplied separately) is available for users to develop their own PLC programs.
