SAFETY PRECAUTION
WARNING
1. Use a lightning surge protector to avoid the risk or injury to operators and
damage to instruments when lightning surge occurs frequently in the working
environment.
2. Make sure the voltage of power supply is proper.
3. Ground the grounding terminal.
4. Carefully check all the wiring before the indicator is powered on.
5. In the case of smoke, abnormal smell or strange sound, immediately cut off
the power.
CAUTION
1. Please do not install the indicator directly in the following environments:
1) Where the temperature or humidity exceeds allowed range.
2) Where the indicator’s main body is easily affected by vibrations.
3) Where exist a mass of dust and powder, such as salt and iron power.
4) Places containing caustic, flammable and explosive das.
5) Where easily to be splashed by water, oil or chemicals.
2. Please take adequate shielding measures when the indicator is used at
following locations:
1) Near power lines
2) Containing strong electrical field and magnetic field
3) Where static or relay noise is generated.
3. Please cut off the power of Indicator before doing the following operations:
1) Installation
2) Wiring
3) Dismounting

1 General Description
1.1 General Description
Tuxon-A weighing transmitter is applied to transmit weight in industrial fields, which
special features are small volume, plenty communicating commands, stable performance,
easy operation and practicability, so it is widely used in concrete and bitumen mixing
equipment, metallurgy furnace and converter, chemical industry and feed, etc. .
1.2 Functions and Characteristics
Applicable to all kinds of resistance strain gauge bridge load cell.
Front panel numerical calibration
Multilevel of digital filter
Automatic zero -tracking
Automatically zero when powered on
16 Bits D/Aoutput: 4-20mA, 0-20mA, 0-24mA, 0-5V, 0-10V, -5-5V or -10-10V
Selectable (for sub-model Tuxon A)
1.3 Front Panel
Keypad:
:Zero/Esc.
Zero Key: Used to clear display data.
Esc Key: Used to exit from current operation or go previous.
:Option Key. Used to scroll optional values of parameter.
And to make flashing digit increase 1 while data inputting.
:Function Selecting Key.
To make flashing position move to the right digit when data inputting.
:Confirming Key. Used to confirm present operation.
Status IndicatorLamp:
2
○ZERO: Light on when present weight is within 0±1/4d.
○STAB: Light on when changes of weight values are within the range of motion detecting
during motion detecting time.
○DATA: Light on when indicator displays the value of D/Aoutput.
Main Display: 6 digits, for displaying weight, value of D/A output, and the information of
parameters.

2.2 Connection of Power Supply
1.AC power must have the grounding protection.
2.Do not connect the ground wire of indicator directly to
the GND of other equipments.
2.3 Connection of Load Cell
Please refer to the picture below to connect load cells to Tuxon-A. When you use 4-
wired load cells, you must bridge the SN+ with EX+ and bridge the SN- with EX-.
The signal definition of each port of the load cell connector is as follows:
