Page 11: The Control On The Pump
7.2 The control on the pump During the operation of pump, control it according to “proportional pressure control” (BL) principle or “constant pressure control” (HD) principle. In these two control modes, the performance of pump and corresponding power consumption should be adjusted according to the heat demand of system. 7.2.1 Proportional pressure control In this control mode, the pressure difference on both ends of the pump shall be controlled by flow. -
Page 12: Interface
8.2 Interface The pump is controlled by external electrical elements and components through interfaces. The interfaces convert external signals into signals that can be recognized by microprocessor in the pump. In addition, when the pump is supplied with 230V voltage, the interfaces can ensure that users will not be at risk of high voltage electric shock when contacting the... -

PWM Input Signal (%) Pump Status The pump switches to non-PWM mode (normal mode), and the default system will have no PWM signal input. <10 The pump runs at the highest velocity 10~84 The pump curve will drop from the highest to the lowest 85~91 The pump runs at the lowest velocity If the velocity variance point of input signal fluctuates, then it will block... -
Page 14: Pwm Feedback Signal
8.5 PWM Feedback Signal PWM feedback signal can provide operation status of the pump, such as power loss or all kinds of alarm/warning modes. PWM feedback signal will feed back exclusive alarming information. If the power voltage detects under voltage signal values, its output signal will be set to 75%. Provided sundries settlement exists in the hydraulic system and causes rotor being blocked, the duty cycle of output signal is set to 90%, the alarm will be given higher priority. -
