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.

(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.

9. Maintenance
9.1 Check the running status of the machine before starting it, ensure that the power
supply of the device is reliably grounded. Normal operation can be put into use. The
external wiring of the equipment must be operated in the power-off state to prevent
burning the equipment.
9.2 Check to see if the tubing is damaged or the equipment is leaking and ensure that
the liquid in the tubing is discharged to the container or discharge pipe. Wipe any
leaked liquid around the pump quickly and correct any possible faults promptly. Keep
the rollers of the pump head clean and dry, otherwise it can hasten tubing wear (it can
also damage the tubing causing solid substances in the liquid), reduce the useful life
of tubing, and lead to quicker damage and wear to the rollers. If the pump head gets
water on it accidently, use a soft, absorbent cloth to wipe it dry to prevent damage to
the pump head. If liquid splashes on the pump, please turn off the power supply and
unplug the power wiring. Check to see if there is liquid in the inner part of the
equipment, if so please contact the manufacturer.
9.3 The factors affecting the flow are as follows:
1) The inner diameter and wall thickness of tubing may have some deviations due
to its tolerance and different bathes.
2) Different liquid properties
3) It will decrease flow rate when input port and output port change incrementally
or there are suction and lift.
4) The speed of DC/AC motor will change according to load, temperature and
humidity.
This may influence product flow accuracy, please leave a margin when choose tubing.
9.4 This product has no waterproof measures. Please take protective measures when
using in a wet environment. When the product will not be in use for a long time, please
clean it and keep it in a dry and ventilated environment.
9.5 Pump head is not resistant to organic solvent (Except for special indication) and
strong corrosive liquids, please be attentive when using either near it.

9.6 The data used for testing in this manual is all short duration and may change for
longer duration use.
9.7 The current will raise over the rated running current when DC/AC motor starts or
blocks, it may be about 3-5 times the rated operating current.
9.8 This product does not have special certification such as medical certification.
When it needs to be used in special fields such as medical and military, please self-
certify. Load changes will also cause changes in operating current. Therefore, please
conduct margin design for power supply power.
9.9 The company shall not bear the direct and indirect losses caused by the malfunction
or improper operation of this product.
