Features
- Integrated full pump control enables standalone multi-pump parallel systems without an external controller.
- Minimum operating units can be set to ensure stable water supply.
- Capable of obtaining system's constant pressure while pump disengages from operation for maintenance.
- Sensorless vector control supports induction and PMSM motors, offering high efficiency and stable performance at all speeds
- Provides fire mode operation, suitable for ventilation system and fire safety equipment in emergency mode.
- Automatic restart upon power interruption or abnormal tripping, with adjustable restart intervals and retry limits.
- The keypad displays the setting value and practical value at the same time.
- Parameters of master drive can be easily copied to slave drive without setting each unit individually.
PID Constant Pressure Control
With built-in multi-mode PID pressure control, auto switchover to slave drive in an event of an abnorality and master/slave rotation functions. Supports up to 8 units in parallel with alternating operation to ensure uninterrupted performance, enhancing system reliability and service life.
Control Modes
-
E-Mode
Multiple pumps run at the same speed. Flow rise rapidly. Steady pressure while drive separates. Suitable for processing cooling water. -
F-Mode
One operates to control speed, others at full speed or standby. Stabilizes pressure effectively. Suitable for general water supply systems.
-
Auto Shift
Master pump and slave pumps operate alternately, prevents slave pumps from idling for too long and cause abnormal situation. -
On / Off Mode
When water pipe leakage is detected, the inverter automatically switches to on-off mode, preventing motor from starting repetitively, lowering noise and lowering power consumption.
Temperature/Differential Temperature Control Mode
Temperature and wet-bulb temperature compensation control, suitable for energy-saving control of fans, cooling towers, and air handling units.
Smart Hand On
The affected pump can be disconnected directly if one of the pump in parallel system fails. and others will automatically take over operation.
Standby Pump B automatically take over the operation when Pump A switches to manual mode, preventing pressure drop.
Fire Mode
The fire mode ensures maximum ventilation and water supply by overriding normal protections,
keeping the system running at full capacity until failure to minimize damage.
keeping the system running at full capacity until failure to minimize damage.
Safety Protection
-
Dry-run / Cavitation
Prevents dry running damage to the shaft and cavitation damage to the blades, ensuring a longer
pump lifespan. -
Over pressure
Automatically alarms and stops operation to prevent pipe bursts or equipment damage if pressure
is too high.
-
Water hammer and noise prevention
Automatically enters buffer mode when there is no water demand to prevent water hammer, protect the piping system, and reduce noise. -
Overheat
Automatically alarms and stops operation when motor temperature is too high. Supports PTC,
NTC, PT100, RTD392, and KTY84 temperature sensors.
-
Auto Restart Function
Automatic restart upon power interruption or abnormal tripping.
