BECSys5

Category: Automated Controllers

BECSys5 water chemistry controls provide continuous monitoring and control of sanitizers, oxidizers, pH, conductivity, turbidity, enzyme feed, system flow rate, system pressures, chemical inventory levels, and surge tank levels.

Patent-pending VFD control technology and Total Dynamic Head monitoring assures optimal and efficient circulation pump operation. Indoor facilities will benefit from the BECSys5’s ability to monitor combined chlorine levels.

<span">Email and Text Message Alarm Notifications are supported by the standard integral 100BaseT Ethernet connection, and integration with Wi-Fi networks is supported with the optional BECSys Wi-Fi module. All inputs and system events are recorded in on-board data logs, accessible with BECSys for Windows Windows 8-compatible PC software, which is included with every BECSys5. The BECSys Now! App for IOS (iPhone) and Android smartphones provides convenient 24/7 access to the BECSys5 status.

Advanced safety features and multi-level security are standard. Every BECSys5 comes complete with pH, ORP, temperature sensors, flow switch, machined flow cell, and start-up and support provided by a factory-trained technician.

The BECSys5 flow cell can be pre-assembled at the factory and mounted with the controller on a back panel for convenient installation. In this configuration a lightweight PVC mounting frame is easily leveled and installed on the wall. The back panel assembly is then hung on the mounting frame through 4 teardrop holes. Tighten the four bolts, make plumbing and electrical connections and installation is complete.

Water Chemistry Control Functions

  • pH: Configurable for feed-up, feed-down, or dual feed, and either ON/OFF or Time-Based Proportional feed.
  • Sanitizer: Based on ORP input, free chlorine input, or bracketed combination of the two
  • Sanitizer Booster: Selectable trigger setpoint and separate ending set point.
  • Ozone: Feed-up based upon ORP and/or ppm set points, Fireman Cycle feature and Energy Conservation mode.

  • Dechlorination: Feed-down control of dechlorination agent, either manually-triggered or automatic upon superchlorination completion
  • LSI & RSI: Langelier Saturation Index and Ryzner Saturation Index, computed based upon current inputs and Ca Hardness and Alkalinity entered by operator.

Energy Conservation Control Functions

  • Alternate Setpoints: Run the pool at less demanding levels during periods of low usage.
  • Energy Conservation Mode: Program a “Sleep” mode which disable all mechanical and chemical functions during off-hours, “waking” periodically to keep water quality in check.

Expanded Control Functions

  • UV (Combined Chlorine) Control: Programmable combined chlorine set point; BECSys5 will activate a relay to turn down UV system when combined chlorine reading is below set point.
  • Flow: Display and log System Flow, maintaining Total Flow Volume; Low Flow alarm can disable chemical feeds.

  • Sensor wash: programmable sensor wash with start and end time, feed duration, and multiple cycles per day.
  • Backwash link: BECSys5 can be linked to a BECSysBW via Ethernet to share recirculation pump control information, fireman switch delays and backwash state.
  • Main Recirculation Pump Control Functions
