Becsys5 Installation And Technical Manual Jun 2026

Change the screen number to match your manual test kit result.

Tracks inventory (acid tanks) and provides flow rate monitoring.

Clean sensors regularly to maintain accuracy. Electrolyte levels in membrane caps must be checked.

Shut off the main breaker before touching wires. Dry Hands: Never touch electrical parts with wet hands. becsys5 installation and technical manual

Disconnect all electrical power sources upstream at the breaker panel before opening the enclosure or making terminal connections. Main Power Input

: Run 3/8-inch or 1/2-inch OD UV-stabilized tubing between the taps and the flow cell. Install dedicated ball valves at both ends for immediate isolation during servicing.

-- Lua example setpoint = 22.5 actual = AI[1] -- Room temp sensor output = PID(actual, setpoint, 2.0, 0.5, 0.1) -- Kp, Ki, Kd AO[1] = clamp(output, 0, 10) -- Valve position 0-10V Change the screen number to match your manual

Pro Tip: Do not touch the glass bulbs of the electrodes with your fingers, as skin oils can interfere with readings.

| Terminal Block | Signal Type | Max Wire Gauge | Notes | |----------------|-------------|----------------|-------| | PWR | 24VAC/DC | 14 AWG | Use twisted pair, fuse at 3A | | GND | Earth | 14 AWG | Connect to panel ground bus | | AI1–AI8 | 0–10V, 4–20mA | 18 AWG | Shielded cable, ground shield at controller end | | DI1–DI12 | Dry contact | 18 AWG | Use 12V internal wetting (configurable) | | AO1–AO4 | 0–10V | 18 AWG | Max load 10mA per output | | DO1–DO8 | 24VAC/DC @ 2A | 16 AWG | Flyback diode required for inductive loads |

Choose a good spot for the controller. It needs to hang on a wall near the pool filtration system.

Multi-level password protection and an emergency "Off" button on the front panel provide both operational security and safety. Essential Maintenance & Calibration Operation and Maintenance Manual - BECSys5 - Aquafinity
