2.5 DEFINITIONS AND CONVENTIONS

ADC:

Analogue to digital converter, converts the analogue signal into a digital signal.

DAC:

Digital to analogue converter, converts the digital signal to an analogue signal, usually after some digital

signal processing.

Dead weight:

Dead weight is the self weight of the platform or scale load carrying structure on the load cells without

the contents or items to be weighed. The output voltage of the load cell in response to the weight of the

platform is usually the zero offset. The zero offset must be within the range of the instrument adjustment

for correct operation.

Live weight :

The weight that is applied to the scale and shown on the indicator.

Excitation voltage:

The voltage that is supplied by the indicator to the load cell.

Load cell:

www.ptglobal.com PT210 Instruction Manual 4

Load cell is a device that converts force to electronic voltage. A load cell consists of two parts. The first

part is a sensor that can be linearly distorted according to the force applied to it. The second part is the

strain gauge element which changes its resistance according to the distortion of the sensor.

Load cell rated output:

The output voltage from the load cell divided by the excitation voltage at load cell rated capacity. This is

usually expressed in mV/V.

Input range:

The maximum range of input that the device can accept. This is usually stated in mV and for a full load

cell system is calculated from the number of load cells (Lcn), mV/V (LCmv) and capacity (LCcap) and

also the maximum total load (TL) (including dead load) on the load cells and the excitation voltage (EV).

Input Range (mV) = TL / (LCn * LCcap) * LCmv * EV

Note: A summing box with corner adjustment will reduce this value slightly.

FSO:

Full scale output. Errors may be presented as a % of the full output range after calibration.

PLU

Product Look Up. A code to look up values stored in product information

CLU

Counting Look Up. A code to look up values stored for counting

APW

Average product weight. Used in parts counting, this is the average weight of one piece of product,

determined by weighing a sample and dividing by the number of parts.

ALU

Amount Look Up. A code to look up values stored in memory in relation to the amounts (quantity) of

parts in check weighing.

Span Adjustment

Adjust the indicator so that when the load on the scale is changed the scale correctly shows the same

change.

 4  GETTING STARTED
 4.1  THE STEPS BEFORE OPERATION
Warning: Please take note of the steps below required to get your scale operating. Each step refers to 
the appropriate location in the manual.
1.Install load cells into weighing system and connect to a junction box for multiple 
load cells.
2.Connect load cells from the junction box to the indicator. 5.3 , p11
Take note of the number of wires and follow the wiring instruction for 4 or 6 wire 
connections.
3.Connect the indicator to the power supply.  5.4 , p11
4.Check to see if access to settings requires a pass code, a switch to be activated or 
a jumper wire to be installed.
5.Configure required settings for communications and I/O ports. 5.8 , p13,  6.3.8 , 
p22.
6.Configure the indicator for the desired weighing range and increment of weight. 
7.4.2 , p43
Note, this is not necessarily the capacity of the load cells, it is good practise to have 
some reserve capacity. For example 4 x 10t load cells may be used for a weighing 
range of 30t.
7.Calibrate the instrument to show zero with an empty scale and  the correct weight 
when loaded (zero and span). There are various methods of calibration, the most 
accurate is generally calibration with a known weight. 7.5 , p43
8.Adjust filter ( 7.3.2.1 , p42)and other settings to suit the operating environment. 
Make sure high resolution display is not activated in normal weighing.  7.4.1.2 , 
p43.
9.Check the configuration to confirm calibration and settings are correct and correct 
operation of the scale by placing a known load on the scale.

5 INSTALLATION

5.1 GENERAL RULES

Warning: Please read this manual carefully before installing the instrument. Applying the

recommendations in this section will increase your system reliability and long term performance.

Control Cabinet

The control cabinet should be designed so that PT210 can operate safely and with highest

performance. The panel should be placed in a clean area, out of direct sun light if possible, with a

temperature between -15 ºC and +55 ºC and humidity not exceeding 85%RH, non-condensing. All

external cables should be installed securely to avoid mechanical damage.

PT210 instruments are very low level signal measuring instruments. To avoid electrical noise they

should be separated from any equipment that produces electrical noise.

•It is preferable to use metal cabinets to protect against radio frequency interference and ensure

the cabinet is connected to ground.

•Load cell cable trays must be separated from others, if possible, as power or motor control

cables can cause interference.

•If there is noise-generating equipment, such as heavy load switches, motor control equipment,

inductive loads etc., please take care to protect against EMC interference in the cabinet and if

necessary protect PT210 instruments with a Faraday cage or install them well separated or in a

separate section well away from this kind of equipment.

•Connect parallel reverse diodes to the DC inductive loads like relays, solenoids etc. to minimize

voltage peaks on the DC power supply.

•If the condition of your plant electrical supply fluctuates or is subject to noise and interference,

prepare a special power line and grounding.

•Good quality grounding of the instruments will improve weighing accuracy and the safety of

your indicator.

Cabling

All cables coming to the control cabinet should be shielded. Please use separate cable trays for these

low signal level cables. The distance from load cell cables, interface cables and DC power supply

cables to mains power line cables must be minimum 50 cm unless they are installed in a properly

grounded steel conduit or you could experience a reduction in performance.

Warning: Please always remember that PT210 instruments are very low voltage measuring

instruments. Your control cabinet design and proper installation increases reliability and performance of

the instrument. Please do not forget that the instrument must be powered off before inserting or

removing any peripheral connector.

5.2 MECHANICAL INSTALLATION

The PT210 indicators are panel mounted from the front with stainless steel front and back parts, and

aluminium body. Dimensions are shown with 1/8 DIN cut out below. The PT210DIN DIN rail mounts.

Install the indicator into the panel from the front with the panel fixing accessories supplied. Be sure to

complete the mechanical installation of your weighing system and the panel installation is finished to

ensure optimum life before starting the electrical installation as described below.

www.ptglobal.com PT210 Instruction Manual 11

5.3 CONNECTING THE LOAD CELL

Warning: After load cell connection to the instrument, welding on the mechanical structure or fittings is

not recommended. Disconnect all connectors from the indicator before any welding on the mechanical

hardware.

The load cell wiring should be installed carefully before energising to avoid damage to the instrument

and load cells. The combined input resistance of the load cells that you want to connect should be more

than 42Ω. Do not bind the load cell cables together with other cables as it could result in cross-talk

interference. Please also keep them well away from the AC power cables.

4 wire LC connection 6 wire LC connection

Load cell connection details are shown above. In 4-wire installations the sense and excitation pins with

the same polarity should be connected together in the connector (connect Sense+ to Excitation+,

Sense- to Excitation-). If you have a junction box in your system, use 6 wire cable between the

instrument and the junction box, and for 4 wire load cells connect Sense and Excitation in the junction

box for better performance.

Warning: Always connect Sense pins to Excitation pins for 4 wire connection. Non-connected sense

pins may cause the wrong Excitation voltage measurement and create an accuracy problem.

Warning: Connect the load cell cable shield to the reference ground or shield pin of the load cell

connector (centre pin).

5.4 POWER SUPPLY AND GROUNDING

The weighing instrument measures very low signal levels. The quality of the power supply and

grounding will affect the accuracy and the safety of your measuring system. It is very important that the

instrument should not share power lines with noise-generating parts such as heavy load switching

relays, motor control equipment, inductive loads, etc. If the condition of the mains power supply in the

plant is poor, install a special mains power line and grounding.

The power supply voltage of the instrument shall be between 12 VDC and 28 VDC. The connection of

power supply to the 24 VDC power supply connector located right - bottom of the instrument is shown

below. Be sure, the power supply is switched of before connection.

Warning: Before modifying the instrument, turn the power off and wait at least for 30 seconds.

Warning: Connect the power supply grounding pin to the reference ground.

NOTE: The power connector ground , case, Excitation -ve, RS232 GND, RS485 are all

connected at the same grounding potential. Electrical noise on any of these connections could degrade

weighing performance.

www.ptglobal.com PT210 Instruction Manual 12
 5.5  ENERGISING THE INSTRUMENT
Check the mechanical installation, grounding, load cell connection and power supply connection to be 
sure correct electrical installation has been completed before energising the instrument. If all previous 
steps have been completed properly, energise the instrument.
 5.6  CONFIGURING AND CALIBRATION
Before using the scale it must be configured (programmed) to display the correct capacity and 
increment and have a number of advanced functions configured in  7  SYSTEM CONFIGURATION 
AND SETUP. The scale must also be calibrated to display the weight correctly as detailed in  7.5  [3__] 
– CALIBRATION PARAMETERS.
Warning: If the scale has been sealed, call a person with authorisation before modifying the scale or 
settings.
To access configuration and calibration settings there is a DIP switch, front of the PT210DIN, rear on 
the other PT210, between the load cell connector and the non-isolated output connector.  On the 
PT210DIN set it to 1, on the other PT210 it is set deep inside the casing and should be set to position 2 
(ON is downward) to change the metrological related parameters including calibration. THE HOUSING 
DOES NOT NEED TO BE OPENED.
 
Note: Configuration and Calibration can be performed from a PC as described in API 17.596 AzComI 
Software for Azure Indicators. This API is supplied on the USB with the instrument.
 5.6.1  PROGRAMMING
Program the instrument according to the needs of your application in this step. 
•Set interface parameters in block [00-] ( 7.2.1 ), RS232 and RS485 serial ports in [01-] ( 7.2.2 ).
•Set configuration parameters in block [1--] ( 7.3 ) for scale functions related with the application 
like saving tare before power off and restart in Net mode and digital I/O related entries.
•Parameters to set up the scale such as zeroing range are in block [2--] ( 7.4 ). Please 
remember these parameter values are restricted for scale usage in trade. The scale capacity 
and division values are also entered in this block.
•If you will be connecting any peripheral devices to the instrument, you have to set the related 
parameters in the PT210. Refer to ( 7.3.3 ) for digital input/output, ( 7.6 ) for analogue output 
programming and ( 7.2 ) for fieldbus interfacing.
Warning: The programming and parameter descriptions are referred later. We recommend you save 
these parameters before the next step in case the settings are lost if calibration fails due to an error.
 5.6.2  CALIBRATION
You will need to calibrate the scale after programming the parameters. You may follow one the 
calibration methods below.
•vCal Electronic calibration without calibration weights. This can be from the key pad or via 
AzCom or fieldbus (including RS-232C ()).
•Full calibration via keys on the instrument by using calibration weights. ( 7.5.1 ).
•Zero adjustment and span adjustment in sequence via keys or fieldbus. Span calibration 
requires a calibration weight unless performed with vCal. You may save just the zero calibration 
if required without continuing to span adjustment.( 7.5.2.1 ).
•Zero adjustment and span adjustment under load, performed in sequence via keys, if the scale 
cannot be emptied when span adjustment is required. Calibration weights are required for span 
calibration. ( 7.5.2.3 ).
You can access the calibration menu from the operation menu by following the description in the “Fast 
access to calibration” section ( 7.1 ). After calibration and after saving the adjustment return to the 
operating menu ( 7.1 )  
Remember: You may use parameter [905]  7.9.1.6  to monitor the load cell output voltage during 
loading for diagnostic purposes if you can not perform the calibration due to errors.

5.6.3 LOCKING CALIBRATION

If the DIP switch has been set to the position (ON) for programming, push it to the other position to lock

the scale adjustment against access by non-authorised persons. If the scale is used in non-trade

industrial weighing, this step is not essential, but is recommended to prevent accidental changes.

5.7 CHECKING SCALE PERFORMANCE

Warning:

•Scale set-up and calibration should be performed according to the needs of your application.

Please read this document carefully and select the parameter values which will fit your

application before programming the instrument.

•You cannot change Set-up parameter values and calibration after sealing the instrument in

legal usage, be sure the proper adjustments have been done before sealing the scale.

Check the scale performance by testing the scale eccentricity, scale linearity with loading up to the

maximum loading value, repeatability, etc. before putting the scale into use.
