| Structure: | Closed-Loop |
| Mathematical Model: | Linear |



| Rated Input Voltage: | 240VAC, 50Hz |
| Rated current : | 0~10A |
| Maximum current: | 40A |
| Qty.of Controlled Pump: | One pump |
| Level Transmission Type: |
•4~20mA Level sensor;
•float switches (4pcs) (backup);
•Pressure switch;
|
| Enclosure: |
•PC Plastic Enclosure, with clear enclosure cover,
•High strength, UV resistance;
•Lockable with all locks;
•Fitted with non-corrosive hinges and locking latch;
|
| Protection grade: | IP65 |
| Display: | 7" LCD touch screen |
| PLC: | 24VDC, I/O: 4 digital input/output; 4 analog input/output; RS485, RJ45 ports, TF card |
| Outer Dimension: | 400 ×300 × 220 mm |
| Installation: | Wall mounting |
| Working temperature: | -25ºC-- +55ºC |
| Working humidity: | 20%--90%RH, no drips concreted |
| Max.Control Distance: | ≤2000m without strong electric and electromagnetic fields |
| Control Function: |
•Low Level - Pump stop;
•High Level - Pump start;
•Low Low Level - Pump stop, and dry run protection alarm will be triggered;
•High High Level - Pump start, and high level alarm will be triggered;
•Pressure monitoring - Pump can be turned off when high pressure alarm triggered;
•Pump running time monitoring - when pump running time exceed the maximum time in a period, the system can send the alarm;
•Pump start, stop delay time can be set, solve the problems such as liquid level fluctuation and water hammer;
•Automatic restart after power recovery etc.
|
| Protection Function: |
•Over-load protection;
•Dry run protection;
•Short circuit protection;
•Over-temperature protection;
•Over-pressure protection;
•Pump leakage protection;
•Over/under-voltage protection;
•Over-flow protection
|
| Data log and storage: |
•Pump run indication
•Number of high levels
•Number of starts (total)
•Number of power resets
•Number of over current shut-downs
•Number of starts per hour
•Motor running current
•Last motor current
•Peak and average current during last run cycle
•Level settings record;
•Data logging with real-time clock;
•Minimum 30 days data storage before it is over-written.
|
| Alarm notification: |
•over-load;
•over- temperature;
•dry turn;
•over-voltage;
•over-pressure;
•pump excess runtime across a 24hr period;
•high level;
•4~20mA level transmitter fail;
•float switches fail;
