Becsys5 Installation And Technical Manual //top\\ Jun 2026

Maintain clear access to the front panel door for calibration and servicing. Sample Stream Plumbing Requirements

: Capable of tracking Total Alkalinity (TA), Free/Total Chlorine (PPM), Turbidity, and even TDS (Total Dissolved Solids). Safety Features :

This is arguably the most critical safety configuration. The failsafe timer sets the maximum length of time a chemical feeder can run. If the controller fails to reach the set point within the selected time (indicating an empty chemical drum or broken pump), the controller will cut power to the feeder and flash the Reset Fail/Safe LED on the face panel.

Before you begin wiring, ensure the mechanical environment is ready.

Optional 4-20mA inputs allow the controller to monitor liquid chemical tank levels, providing alerts before an acid or chlorine tank runs empty. 4. The Intelligence: "Automation and Efficiency"

: According to the official BECSys5 Operational Manual , you must physically mount all major subcomponents and complete flow cell plumbing before establishing any electrical connections. Step 2: Mechanical & Flow Cell Plumbing Setup Maintain clear access to the front panel door

Use or the provided flexible compression tubing to bridge the main lines to the flow cell. Install dedicated, manual isolation ball valves on both sides for zero-downtime maintenance.

| Symptom | Likely Cause | Resolution | |---------|--------------|-------------| | No LEDs on power-up | Blown fuse or reversed polarity | Check 24V supply, replace 3A fuse | | BACnet device not visible | Wrong UDP port or instance duplicate | Change instance, reboot, check firewall | | AI reads 10V with nothing connected | Floating input | Enable 10k pull-down resistor in software | | DO chattering | Inductive kickback | Add flyback diode (e.g., 1N4007) across load | | Web UI slow | High CPU from Lua script | Reduce loop sleep to min 100ms |

: Thread the inlet sample line into the main filtration piping after the pool filter but before any chemical injection points or heating systems . This ensures the probes read clean, filtered water before raw chemicals skew the data. The failsafe timer sets the maximum length of

If offline, use the offline activation file ( request.c2v ) sent to support@becsys.com.

: Use a NEMA 4X (IP65) rated enclosure for protection. Ensure the location has adequate ventilation and is not in an explosive environment.

This technical manual serves as an exhaustive reference guide for commercial pool operators, field technicians, and facility engineers responsible for the deployment and upkeep of the BECSys5 controller. 1. Product Overview and Technical Specifications
