Coteq Solutions’ Automatic Test Module is a ‘Secondary control system health check monitoring device’ for small pumping stations, providing assurance that hardwired backup systems will initiate in the event of primary systems failure.

A Pumping station often has two levels of control:

• A primary control system that controls the pumps. (often on level with duty regimes).
• A secondary ‘hardwired backup circuit’ which is designed to run if the primary control fails.

Hardwired backup systems can remain idle for prolonged periods. Without regular monitoring, there is a risk the backup circuit will not operate when required, which leads to the potential of pollution events.

The CQS-HWB-ATM, Automatic Test Module, is designed to test the hardwired backup cycle at regular intervals, providing confidence that it will operate when required, and doing so without switching from primary control.

The Automatic Test Module can easily be integrated into most existing hardwired backup circuits and is a simple retrofit due to its compact size and straightforward integration into existing panels.

Benefits:

• Minimises Pollution risk: By regularly testing the backup circuits, the risk of pollution events on site are lowered significantly.
• Reduces need to attend site: Automatic testing and the additional function to remotely test the hardwired backup, reduces need for on-site checks of the operation of the Hardwired backup circuits.
• Test times optimised: The times at which the Testing is run can be controlled to fall within working hours, minimising any call out costs for faulty hardwired backup resolution works required
• Minimises the health and safety risk of float switch manipulation: Due to the automatic function of regularly running the backup systems, the need to undertake site manipulation of float switches (requiring access to wet well hatches etc) is reduced significantly.
• Clear visibility on the ‘health’ of every pumping station backup: Consistent backup testing functions across all sites promptly reports any issues.
• Very compact: 120mm x 120mm x 95mm (Footprint is not much larger than a fused spur enclosure). Fits inside most existing MCC Control sections
• Simple to install: Simple connectors for all I/O and power.

Highlights:

• Integrates into existing hardwired backup systems.
• Enables hardwired backup circuits to be exercised regularly, ensuring backup circuits are available in the event of primary control failure.
• Extremely compact; fits into most existing MCC control sections.
• Provides test result as inputs into SCADA (Test OK and Test Failed)
• 24V DC.
