Remark: Above table sums up the associated input signals.
a. Digital input:
When external control of digital input is enabled, the pump has a 7-wire cable
((PIN1/2/3/4/5/6/7) with open ends; to connect from PIN1 to PIN5, the assignment of the
cables to the individual speeds is as below:
When PIN4 connect with PIN5, the pump will be mandatory to stop; if disconnected, the dig-
ital controller will be invalid;
When PIN3 connect with PIN5, the pump will be mandatory to run at 100%; if disconnected,
the control priority will be back on panel control;
When PIN2 connect with PIN5, the pump will be mandatory to run at 80%; if disconnected,
the control priority will be back on panel control;
When PIN1 connect with PIN5, the pump will be mandatory to run at 40%; if disconnected,
the control priority will be back on panel control;
The capacity of inputs (PIN1/2/3) could be modified according to the parameter setting.
b. Analog Input:
When connected with PIN8 and PIN9, the running capacity could be determined by 0~10V
analog voltage signal or 0~20 mA analog current signal.
The following table shows the relationship between the analog signal on input and the set
value to be activated:
Analog control
Current (mA)
Voltage (V)
The default control mode is by current signal, if you want to change to voltage signal, please
enter the parameter setting. (see 5.7)
c. RS485:
When connected with PIN6 and PIN 7, the pump could be controlled via Modbus 485 com-
munication protocol.
d. Relay output:
The output is made from a relay L and N, with the following electrical characteristics.
