7. Wilo-Para iPWM2 Pump The Wilo Para 25/7 iPWM2 is a wet running circulation pump. The pump speed is controlled by the PWM signal. When the PWM signal is disconnected, the pump stops running (a pump profile for solar thermal systems). The operating status and possible faults of the pump are indicated by LEDs directly on the pump. - Page 9 7.3 Graphic signalling of pump operation The LED light signals a defect. The pump will switch off (depending on the defect type) and try to restart. LED Signals State Description and Possible Fault Reasons GREEN IS LIT 1 - pump is running in trouble-free operation 1 - rotor is blocked RED IS LIT 2 - electric motor winding defect...
