External Control Interface
The external control interface of 15 hole base is shown in the figure below:
l
The external control interface is 15 hole base, the function of 15 hole pin is:
Pin1 is the external control start/stop port;
Pin2 is the external control reversing port;
Pin3 is empty.
Pin4 is RS485 B-;
Pin5 is ;
Pin6 is 0-5V signal terminal of analog speed regulation;
Pin7 is 0-10V signal terminal of analog speed regulation;
Pin8 is 4-20mA signal terminal of analog speed regulation;
Pin9 is AGND common port of analog speed regulation;
Pin10 is empty;
Pin11 is negative terminal (POWER_GND) of status output;
Pin12 is status output terminal;
Pin13 is positive terminal (POWER_VDD) of status output;
Pin14 is the positive terminal of internal isolated 5V output;
Pin15 is the negative terminal of internal isolated 5V output.

External control start/stop, reversing:
Set external control mode in external control setting interface, turn on corresponding external control function, the external control signal
input port is valid.
Ø
Pin1 is the external control start/stop port
:
In pulse mode
, pin1 is short-circuited with pin14 and then disconnect, the motor will run, do it one more time, the motor will stop;
In
level mode
, pin1 is short-circuited with pin14, the motor will run, disconnect them, the motor will stop.
Ø
Pin2 is the external control reversing port:
In pulse mode
, pin2 is short-circuited with pin14 and then disconnect them once, the motor direction will change once;
In level mode
,
pin2 is short-circuited with pin14, the motor will run with clockwise, disconnect them, the motor will run with counterclockwise.
Ø
Pin14 is the common port of external control start/stop, reversing
Note:
1)
When the external control is turned on level mode, the membrane keypad will not make effect.
2)
The pump defaults to passive external control signal, the above description is also the default state. If you need active
external control signal, please contact with manufacture.

RS485 communication port:
Select pump address and communication baud rate in communication setting interface.
Ø
Pin5 RS485A:
Connect RS485 A+ port
Ø
Pin4 RS485B:
Connect RS485 B- port
Note: The communication protocol is standard MODBUS protocol.
(3)
Analog signal input port:
After selecting external control speed regulation signal in external control setting interface, turn on the
