This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
A learner credited with this unit standard will be able to perform corrective preventative maintenance on an axle counter according to prescribed corrective tasks, by applying signalling engineering practice. The learner will also be able to identify, prioritise and report any potential failure maintenance tasks. This will ensure the availability of functional axle counters as required, which contribute in part to a reliable railway signalling system, safe and efficient train operations and effective rail transportation. 

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
  • Communication NQF L2
  • Mathematics NQF L2
  • Knowledge of the principles of electricity.
  • Knowledge of electro-mechanical principles.
  • Knowledge of the relevant statutory requirements related to performing CPM on an axle counter.
  • Knowledge of the company rules and regulations applicable when performing infrastructure maintenance in the vicinity of or near exposed "live" high-voltage overhead track equipment.
  • Apply train working rules as applicable to railway signalling maintenance personnel when working on or in the vicinity of operational railway lines.
  • Principles of train operating methods and railway signalling.
  • Ability to use engineering hand and power tools.
  • Knowledge and use of electrical measuring instruments.
  • Knowledge of and ability to assemble, wire and install parts and components of an axle counter.

  • UNIT STANDARD RANGE 
    The credit value assigned to this unit standard is appropriate because performance must be carried out:
    1. In a controlled environment
    2. Within a specific time
    3. At a field site (might or might not include overhead traction equipment)
    4. Under simulated or actual operational conditions

    When overhead traction equipment is present, the learner must have a valid certificate related to high-voltage equipment, which certifies the learner to work under the specific conditions.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
