Compact Peristaltic Pump
Operation Manual

Note:
Please read the manual carefully before operating the product.
Warning:
Connect the power cord to the wall socket directly, and avoid using a power
extension cord.
If the power cord or plug has wear or other damage, please disconnect the plug.
(Hold the plug instead of the wire.)
If following situations happen, 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 needs to be maintained or repaired.
The user's power socket must have a ground wire with 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.

1. Product Introduction
FCS KA (SS), with low noise and stable operation, is driven by an integrated stepper
motor with a compact structure. The product adopts OLED blue screen display and
has an external control interface, which can realize remote control. It can communicate
with a computer through standard Modbus communication protocol (RTU mode).

Start/Stop Button
Pumps start/stop can be controlled by this button. Press this button once, the pump
working status change once. When the drive runs, the screen displays ‘▶’, when the
pump stops, the screen displays ‘■ ’.
Direction
This button is used to change the motor running direction. Press this button once and
the running direction of pump changes once.
External control button
This button is used to change the method of analog speed control. Press this button
once and that will cycle the display: Empty→5V→10V→mA→Empty. Respectively
corresponding to: Turning off analog speed regulation→0-5V→0-10V voltage analog
speed regulation →4-20mA analog speed regulation →Turning off analog speed
regulation.
Note: If you keep pressing this button and turn on the power supply of this device at

the same time, it will initialize the device and all the parameters will be lost.
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, turn counterclockwise to decrease the speed. 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 rotate the digital knob to change the value. After setting, press the digital
knob to save the data and the screen no longer flashes.
4. External Control Instruction
FCS KA (SS) series has a 15-pin interface for the external control interface, as the
below figure shows. That includes the function of external control start/stop, direction,
analog speed regulation, communication, and status output.

(1) Passive external control start/stop, direction
Pulse mode:
Pin1 to Pin14, short circuit break (pulse mode) is start, short circuit break again is stop.
Pin2 to Pin14, short circuit break (pulse mode) is direction.
Level mode:
Pin3 is external control level mode switching. Short circuited Pin3 and Pin14 to switch
to external control level mode.
Pin1 to Pin14, short circuit is start, breaking them is stop.
Pin2 to Pin14, short circuited, motor is counterclockwise, breaking them, motor is
clockwise.
Note: External start/stop and direction is defaulted to passive signal when leaving
factory. This interface could be connected with a foot pedal equipped by our company.
(2) Active external control start/stop, direction
Pulse mode:
Pin10 connects with negative pole of active external control signal.
Pin1 connects positive pole of active external control signal, short circuit and then
disconnect, the motor will start. Do it again, the motor will stop.

Pin2 connects positive pole of active external control signal, short circuit and then
disconnect, the motor will change direction. Do it again, the motor will change
direction again.
Level mode:
Pin10 connects with negative pole of active external control signal.
Pin3 is the pin of external control level mode switching. Short circuited Pin3 and
positive pole of active external control signal switches to external control level mode.
Short circuited Pin1 and positive pole of active external control signal is start, breaking
them is stop.
Short circuited Pin2 and positive pole of active external control signal, the motor is
counterclockwise, break them, the motor is clockwise.
Note: The active external control isolated signal is 5V, 12V, 24V (Universal)
(3) Analog speed regulation
0-5V voltage signal speed regulation
Choose the analog speed regulation signal of the pump to 0-5V voltage signal by
external control button. The analog signal is displayed “5V” in the screen.
Voltage 0-5V speed regulation, Pin6 connects to the positive pole of voltage analog 0-
5V signal. Pin9 to the connects negative pole. Change the voltage value of the analog
signal and the speed changes linearly. 0V corresponds to speed 0rpm, 5V corresponds
to maximum speed.
0-10V voltage signal speed regulation
Choose the analog speed regulation signal of the pump to 0-10V voltage signal by
external control button. The analog signal is displayed “10V” in the screen.
Voltage 0-10V speed regulation, Pin7 connects to the positive pole of voltage analog
0-10V signal. Pin9 connects to the negative pole. Change the voltage value of the
analog signal and the speed changes linearly. 0V corresponds to speed 0rpm, 10V
corresponds to maximum speed.
External control button for current signal speed regulation
Choose the analog speed regulation signal of the pump to current signal and the analog

signal is displayed “mA” in the screen.
Current 4-20mA speed regulation, Pin8 connects to the positive pole of current analog
4-20mA signal. Pin9 connects to the negative pole. Change the current value of the
analog signal and the speed changes linearly. 4mA corresponds to speed 0rpm, 20mA
corresponds to maximum speed.
Note: DO NOT connect the 0-5V/0-10V signal with 4-20mA input terminal. Wrong
connections may cause damage to the device. The external control plugs must be
connected and disconnected in the power-off status to prevent the external control
interface from being burned.
(4) Output signal
1) Connect Power-VDD with the positive pole of external connection power supply
5 V.
2) Connect Power-GND with the negative pole of external connection power
supply 5V.
3) Start motor, relay pull-in; Motor stops, relay breaks.
