Module 1 - Normal Wet Weather Operation:

The module will provide Delegates with the understanding of the LTT SCADA normal wet weather operation, the systems required to provide the information within LTT SCADA and how the system will operate in automatic mode.  On completion of the training, Delegates are expected to understand:

• The purpose of the LTT SCADA Supervisory PLC;
• The Tunnel Control mimics;
• The tunnel ventilation system in automatic mode
• The worksite Tunnel level in Normal wet weather mode;
• How to manually amend potential spill events.

Module 2 - Plant Exercise Systems:

The module will provide Delegates with the information and practical experience needed to run exercises on the systems provided by the System integrator.  On completion of the training, Delegates are expected to understand:

• The data exchange between the Worksite and the LTT SCADA (Supervisory PLC);
• How to set and reset exercise routines;
• The Exercise Routine Alarms;
• The required setpoints.

Module 3- Extreme Wet Weather Operation:

This module will provide delegates with the skills needed to understand and operate the LTT SCADA System during extreme wet weather.  On completion of the training, Delegates will be expected to understand:
