Check for leaks around the sample tubing, flow cell body, and sensor O-rings.
The BECSys5 is a richly featured water chemistry controller based on a proven design with years of reliable field performance. It is a rugged, microprocessor-driven system designed to automate and precisely monitor the chemical balance of water in commercial and industrial aquatic facilities, from hotel pools and waterparks to large aquatic centers. While configurable for the most demanding applications, it is simple to operate with detailed on-screen manuals and help information. This guide provides a complete installation and technical reference for engineers, technicians, and facility managers.
: Locks out chemical feed if it detects a lack of circulation, ensuring sensors aren't monitoring stagnant water. becsys5 installation and technical manual
: Includes pH, ORP, and temperature sensors as standard equipment.
: The unit is housed in a NEMA 4X (IP66) rated enclosure, making it water-resistant but not suitable for explosive environments. It requires adequate ventilation to maintain operating temperatures between -18°C and 50°C. Mounting Options : Kit Form : Arrives unassembled for custom wall mounting.
: The chlorine sensor requires a one-hour polarization period after installation before it can be accurately calibrated.
BECSys5 uses a block-diagram language called (similar to Function Block Diagram). Common blocks: Tell the system if you use liquid chlorine, gas, or cal-hypo
The BECSys5 offers three flow cell configurations:
: Through the BECSys Live! portal , operators can access real-time data and receive alarm notifications via email or text on smartphones and tablets. Maintenance & Troubleshooting
If you need help with a specific step, let me know. I can give more detail if you tell me: Your (indoor or outdoor)
The controller features a Gbit Ethernet connection with EZConnect and full MODBUS TCP/IP support. This allows the BECSys5 to communicate with third-party Building Management Systems (BMS), Energy Management Systems (EMS), Building Automation and Control (BAC) systems, or SCADA systems. It is a rugged, microprocessor-driven system designed to
Supports direct monitoring via optional amperometric sensors.
