1.1 Overview
The LM40B peristaltic pump peristaltic pump uses a cost-effective processor to
control the stepper motor, and uses multiple independent LEDs to display the
status (including positive/negative rotation, foot pedal mode F1/F2, motor
movement/motor stop, external control trigger, etc.).
1.2 Product Features
The product can be adjusted the speed by keyboard panel or rotary encoder. The
LED displays the positive/negative rotation, foot switch status, whether the
motor is running, whether the external control interface is effective, etc.
The display is intuitive, the operation is easy & convenient, and the content
is simple. Motor subdivision is adaptive, and speed control accuracy is up to
±0.1rpm. The product support rich application scenarios, keyboard control
mode, RS485 communication control mode, external control mode (Multiple signal
conversion modules are optional) and passive contact output for motor working
status.

Chapter 5 External Control Mode
5.1 External Control Mode
(1) When external control module is plugged in, the EXT external control
indicator lights on and the machine switches to external control mode
automatically.
(2) Under external control mode, keyboard control is not supported; When the
external control mode is removed, the machine will switch to the keyboard
control mode automatically.
(3) Under external control mode, steering control, triggering start and stop
and speed adjustment are supported.
EXT-DIRno matter when the motor stops or runs, the direction of rotation can
be switched. If EXT-DIR signal is floating or high, it means positive
rotation, and if EXT-DIR is low (GND short-circuit), it means negative
rotation.
EXT-ST (The wire jumper determines whether to turn on the start/stop switch).
Suspended or high Ext-ST signal means stop, and low Ext-ST (short circuit with
GND) means start
ADC-INit determines the rotation speed. Actually applied external input
signal, which might be 0-5V, 0-10V, 4-20mA or 0-10KHz, etc., finally convert
to 0-3.3V by the external control module, and the voltage has a linear
relationship with the speed.
5.2 External Control Speed Module
Type of external control speed signal
0-3.3V external control speed
0-5V external control speed 0-10V external control speed 4-20mA external
control speed 0-10KHz external control speed
Remark The voltage signal of 0~3.3V is directly applied to the ADC-IN
port. Require 0~5V/10V to 0~3.3V dedicated conversion module.
Require 0~10V to 0~3.3V dedicated conversion module.
Require 4~20mA to 0~3.3V dedicated conversion module. Require 0~10KHz to
0~3.3V dedicated conversion module.
Note: External control speed will correspond to the range from 0 to maximum speed. Due to the error of AD collection, the actual minimum speed will be greater than 0.1rpm, and the actual maximum speed will be less than the theoretical set maximum speed
15
5.2.1 0-5V /10V external control speed module Schematic diagram
5.2.2 4-20mA external control speed module Schematic diagram
5.3 Maximum Speed Setting
The maximum speed is set through RS485 when the motor stops, see the 0x07
command in chapter 4.2.
When the instrument leaves the factory, the appropriate maximum speed will be
preset according to the pump head/pump tube. The user does not need to set.
5.4 Foot Pedal Control Mode
(1) Plug in the dedicated pedal module. One of the pedal mode indicators
(F1/F2 ) lights on, and the machine switch to pedal control mode
automatically.
16
(2) In the foot pedal control mode, keyboard control is supported, but it is
the pedal switch that determines the final running status of the motor. That
is, in F1 mode, the pedal can start and stop the motor, or the keyboard can
start and stop the motor; in F2 mode, the status of the pedal switch plays a
decisive role, and pressing the key at this time will interfere with the
execution effect of the foot pedal.
(3) In the foot pedal control mode, the suction angle is effective when the
motor stops. (4) In the foot pedal control mode, the veer key is valid, and
EXT-DIR is also valid. EXT-DIRNo matter when the motor stops or runs, the
direction of rotation can be switched. If EXT-DIR signal is floating or high,
it means positive rotation, and if EXT-DIR is low (GND short-circuit), it
means negative rotation. FT-EN If the signal is suspended or high, the pedal
is disabled, and if the signal is low (GND shortcircuit), it is enabled. FT-SW
If the signal is suspended or high, the motor stops under foot pedal mode, and
if the signal is low (short circuit with GND), the motor runs. (5) When the
foot pedal switch is removed, the machine will switch to the keyboard control
mode automatically. F1/F2 indicator lights off.
