Pump Threshold Configuration
Pump thresholds in manifolded systems dictate tank switching, continuing pumping for 10 seconds after the threshold is reached for uninterrupted fuel delivery.
Understanding Pump Thresholds in Manifolded Tank Operations
In line-manifolded tank setups, the pump threshold is a critical parameter defining when the TLS-450 PLUS system transitions pumping operations from one tank to the next available resource. This isn’t an immediate switch; the system intelligently continues drawing fuel from the current tank for an additional ten-second duration after the pre-set volume threshold is breached.
This deliberate delay serves to prevent disruptions in fuel dispensing, ensuring a consistent and uninterrupted flow to the customer. Effectively, the threshold isn’t a hard cutoff, but rather a trigger initiating a controlled handover. Optimizing this setting is key to maximizing the sequential utilization of multiple tanks, guaranteeing consistent fuel availability and efficient distribution across your fueling infrastructure. Proper configuration enhances operational efficiency.
Setting the Pump Threshold Value
The TLS-450 PLUS ATG allows precise programming of the pump threshold, tailored to your specific tank configuration and operational needs. Access the Dispense Mode settings through the ATG Control Console to define this critical value. Consider factors like pump flow rate, tank capacity, and desired fuel switching behavior when determining the optimal threshold.
A lower threshold value will initiate tank switching sooner, potentially maximizing tank utilization but increasing the frequency of switches. Conversely, a higher value delays switching, providing a more stable fuel supply but potentially leading to uneven tank depletion. Careful calibration and testing are essential to achieve the desired balance and ensure smooth, reliable operation.
10-Second Delay Before Tank Switch
The TLS-450 PLUS incorporates a built-in 10-second delay feature, activated when a tank reaches its programmed pump threshold in manifolded systems. This crucial function prevents rapid, disruptive switching between tanks during dispensing. It ensures the current tank continues pumping for a short period, even after falling below the threshold, maintaining consistent fuel delivery.
This delay minimizes customer inconvenience and avoids potential issues with pump operation. It’s a standard setting designed to optimize the sequential use of multiple tanks, providing a smoother fueling experience. The delay is automatically applied once the threshold is breached, requiring no manual intervention.

Dispense Mode Programming
Dispense Mode allows customized tank activation based on fuel height or volume, optimizing pump configuration and providing site managers with total inventory control.
Activating Tanks Based on Fuel Height
The TLS-450 PLUS ATG offers a dispense mode enabling tank activation based on precise fuel height measurements. This feature is particularly useful for sites requiring a specific fuel level trigger for switching between tanks.
Operators can program the system to initiate pumping from a new tank once the current tank’s fuel height reaches a predetermined low point. This ensures consistent fuel availability and prevents running a tank completely dry.
Careful calibration of the tank probes is crucial for accurate height readings and reliable tank switching. The system’s programming interface allows for easy adjustment of these height thresholds to match specific site requirements and fuel management strategies.
Activating Tanks Based on Fuel Volume
The TLS-450 PLUS ATG’s dispense mode allows for sophisticated tank activation based on precise fuel volume calculations. This method provides a more direct approach to fuel management, ensuring optimal tank utilization and minimizing waste.
Operators can define specific volume thresholds for each tank, triggering a switch to the next available tank when the current one reaches that level. This is especially beneficial for sites with varying fuel demand and complex tank configurations.
Accurate tank calibration and volume measurements are essential for this feature to function effectively. The system provides tools for precise volume programming, ensuring reliable and consistent fuel dispensing operations.
