Note:
Ø Please read the manual carefully before operating the product.
Warning:
Ø The tube may have crack due to wear. It results in the overflow of fluid from tubing. In that time human body and instruments may
be harmed. So users must check frequently and change tubing in time.
Ø Connect the power cord to the wall socket directly, and avoid using the extended electric wire
Ø If the power cord or plug had wear and other damage, please disconnect the plug. (Hold the plug instead of the wire).
Ø If following situations happened, please turn off the power supply and disconnect the plug. (Hold the plug instead of the wire)
1. Fluid splash on the pump.
2. You think the pump need to maintain or repair.
Ø The user's power socket must have ground wire and a reliable grounding.
Note: The foot pedal switch and other external control plugs must be connected and disconnected in the power-off status to prevent the
external control interface from being burned.

3. Operation Panel
Ø Start/Stop Button
Control the pumps start/stop, press this button once, the pump working status change once. When drive runs, the screen display ‘▶’, when
the pump stops, the screen display ‘■ ’.
Press the Start/stop button and in same time turn on the pump, to reset the pump.
Ø Change Direction Button
Control the pump running direction, press the change direction button once, the pump working direction change once.
Ø Digital Knob
The digital knob used to increase or decrease the motor speed.
(1) In the running state, the digital knob is used to adjust the speed. Turn clockwise to increase the speed, and vice versa. If you keep
pressing the digital knob, the motor will run at the highest speed (full speed), and release it to return to normal speed.

(2) In the stop state, press the digital knob, the lower right corner of the OLED flashes and the value is RS485 communication address
(1~32). At this time, you can turn the digital knob to change the value. After setting, press the digital knob to save the data and the
screen no longer flashes.
(3) Press the digital knob and in same time turn on the pump to check the program version number and the SN code of the pump.
4. External Control Instruction
①
. RS232 Communication Port
Serial 232 communication interface, this interface is directly connected to the computer’s serial interface, the protocol is Modbus
protocol.
②
. Analog Signal Input Port: Control the motor speed from 0 rpm to maximum speed through analog signal.
0-5V/0-10V: 0V to 5V/10V voltage signal input port.
First, short-circuited the external control identification port (IN3) and GD2, the default is 0-5V speed control. Connect the 0-5V pin of the
green terminal to the positive pole of the analog signal, and connect the GND pin to the negative pole of the analog signal. At this time,
adjusting the analog signal speed will change accordingly.
4-20mA: 4 to 20mA current signal input port
First, short-circuited the external control identification port (IN3) and the 0-5V/4-20mA speed control conversion interface (IN4) with GD2,
at this time it is 4-20mA speed control. Connect the 4-20mA pin of the green terminal to the positive pole of the analog signal, and connect
the GND pin to the negative pole of the analog signal. At this time, adjusting the analog signal speed will change accordingly.
GND: Analog signal negative terminal.
Note:
Ø The factory default of voltage analog speed control is 0-5V. If customers need 0-10V speed control, please contact us for technical
support.
Ø It is forbidden to connect the 0-5V signal to the 4-20mA input terminal, the wrong connection may cause damage to the equipment.
The external control port plug must be plugged and unplugged when the power is off to prevent the external control port from being
burned.

. External Control Start/stop Signal Input Port
GD2: External control signal common port
VDD2: Isolated voltage signal input port
IN1: External control start/stop signal input (pulse signal), after adding external control isolation power supply between VDD2 and GD2,
IN1 and GD2 are short-circuited and then disconnected, the motor starts to run, and after short-circuiting again, the motor stops.
IN2: External control direction signal input terminal (pulse signal), after the external control isolation power supply is added between
VDD2 and GD2, IN2 and GD2 will be disconnected after each short connection, and the motor running direction will change once.
IN3: External control identification port, after the external control isolation power supply is added between VDD2 and GD2, the IN3 pin
and GD2 pin are short-circuited for the external control speed adjustment identification, and there are related indications on the OLED
screen.
IN4: External control speed 0-5V/4-20mA switch. Add an external control isolation power supply between VDD2 and GD2 and
short-circuit IN3 and GD2.
At this time, the IN4 pin and the GD2 pin are short-connected for 4-20mA external control speed control. At this time, the current signal is
connected to the 4-20mA signal inlet, and the OLED display
Wiring connection as in below Picture A.
After the IN4 pin is disconnected from the GD2 pin, it is 0-5V external control speed control. At this time, connect the voltage signal to the
0-5V signal inlet, and the OLED display
Wiring connection as in the below Picture B.

Note:
Ø The external control isolation signal is 5-24V universal, and the voltage can be directly connected to the isolation signal input
terminal.
Ø FCS KA (SS) can connect with foot pedal switch. If need, please contact with us.
Ø The FCS KA (SS) has an open-collector output, which indicates the running status of the motor. If need, please contact with us.

8. Maintenance
Ø When the pump does not work, please loose the upper block which press the tubing for avoiding changing the shape of tubing
because of longtime extrusion.
Ø The pump head cannot resist to super corrosive liquids, please pay attention to this when use the pump.
Ø Keep the pump head rollers clean and dry. If the rollers is not clean, it will increase the tubing wearing, shorten the tubing life and
make the rollers damage very soon.
Ø If there is liquid drop on the rollers, clean it as soon as possible. Longtime moisture can damage the roller.
