The JMB or JMC microcomputer control system serves as the central controller for the entire soft water system, utilizing advanced microprocessor technology. It offers a wide range of functions including flow display, remaining water amount indication, pre-set regeneration programs, real-time status monitoring, signal feedback, solenoid valve control, and more. This controller ensures efficient and reliable operation of the water treatment system.
The JMB/JMC controller includes 13 key features:
- Password protection to prevent unauthorized access.
- Support for single-channel (JMB) or multi-channel (JMC) meter pulse reception.
- K-value selection for the flowmeter probe based on pipe size.
- Real-time flow display (0–9999 t/h) and remaining volume display (1–9999.9 t).
- Function to view and reset accumulated flow data.
- Status indicators for system operations (working, regeneration, standby, feedback).
- Manual initiation of regeneration from the local panel.
- Adjustable regeneration start time (2–9999 seconds).
- Multiple working mode options: JMC (C1, D2, D3, E2, E3) and JMB (C1–D5).
- Output of auxiliary contacts for outlet solenoid valve control.
- Power failure protection with parameter retention over 3 years.
- Durable housing made of engineering plastic, offering dustproof, anti-corrosion, and waterproof properties.
- Installation options include wall or bracket mounting.
The flow meter is a critical component in the system, directly affecting the accuracy and reliability of regeneration cycles. The JMTT type flow probe from Jie Ming is used for its high performance and precision.
The JMA multi-valve controller manages the full cycle of ion exchange tank operations, receiving signals from the JMB or JMC controllers to initiate regeneration. It includes a signal distributor that controls diaphragm valves via a rotary pilot valve, enabling fully automatic system operation.
Key features of the JMA controller include:
- Password protection.
- Calendar display.
- Regeneration step and time display.
- External signal control and step output.
- Multiple start methods: timed, interval, remote, temporary, or forced.
- Forced step initiation for on-site testing.
- Automatic return to original position.
- Customizable regeneration steps (1–8) and time settings (5–9999 seconds).
- System status feedback.
- Long-term power failure protection.
- Durable, weather-resistant casing.
Installation involves assembling the system according to manufacturer guidelines. Components are shipped in parts and reassembled on-site. Resin tanks and metering boxes are positioned carefully, ensuring proper alignment and verticality. Pipelines, valves, and signal distributors are connected following detailed drawings. All connections must be securely fastened, with proper wiring and a dedicated power supply. The system requires 1–2 amps at 220V, using three-strand flexible wire compliant with local electrical codes.
Control units are mounted on designated brackets. Control lines are connected as per schematics, and power is tested to ensure normal operation. After installation, the system undergoes a test run, starting with backwash, followed by salt absorption, replacement, and final rinse. During this process, all components are checked for leaks and proper function.
For parameter setting, the water production capacity is calculated based on resin volume and raw water hardness. Industrial salt requirements and saline solution volume are also determined. Parameters are input into the JMA controller through a simple menu interface, allowing users to adjust backwash, regeneration, and rinse times. For forced regeneration, specific steps are followed to initiate the process manually. Similarly, the JMC controller allows batch program modifications and forced regeneration across different tanks, ensuring flexibility and control over the system’s operation.
