DEFINITIONS AND CONVENTIONS
The following accessories are available for separate purchase.
•
Metrological sealing kit as used on approved scales to prevent tampering or interference.
•
RS-232C cable with null modem wiring and 9 pin connector for PC connection.
•
RS-232C to USB adapter.
•
Load cells, cable and junction boxes are available on the PT web site.
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:
PT210 Instruction Manual

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.

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,
p22.
6.3.8 ,
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

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.
Load cell Grounding and protection
Power Supply 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.

ENERGISING THE INSTRUMENT
5.6
CONFIGURING AND CALIBRATION
12
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.
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.
Location of configuration DIP switch - PT210DIN
Location of configuration DIP switch
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.

value is displayed. An [E E E] prompt at power on indicates the zeroing range at power on has been
exceeded or the scale was not unloaded at power on. Possibly the indicator parameters have also not
been configured. The scale should be unloaded before power on ( 8 TROUBLE SHOOTING).
Place the object you want to weigh on the scale. The correct weight of the object is shown on the
display after the ~ symbol has gone out.
If the load on the scale is out of the calibrated range (too low or too high) the display will show as below.
Too low.
Too high.
6.2.1 Zeroing
Zeroing is performed to compensate for deviations from zero of the unloaded scale. Sometimes there
can be some small build up of material or drifting out of the automatic zero band.
•
Clean the unloaded platform and check if there is anything touching the platform.
•
Press the [ZERO] key to compensate for the zero deviation. Zeroing can be performed if the
scale is stable and within the zero setting range.
•
The >0< sign appears to indicate that zeroing is complete and the scale is at center of zero.
•
If zeroing is has not succeeded, wait for the ~ sign disappear and press the [ZERO] key again.
6.2.1.1 Zero at Power On
The zero point can be corrected automatically at power on to compensate for zero drifts of the scale if
the scale is always powered on when unloaded. This feature should be disabled for tank, silo, hopper
scales etc.
Power on zero has a limited range and the instrument shows the [ E E E ] error prompt in the case of
out of range. Press the <F> key to read the residual drift and to start weight indication without zeroing
and call service.
Warning: Automatic zeroing at power on can be enabled only if the scale is always unloaded before
power on. This function should be disabled for tank / silo weighing applications or you will no longer
know the content weight.
6.2.1.2 Automatic Zero Tracking (AZT)
The zero point is corrected automatically for minor deviations if the change is within the range limited by
the zeroing range value. Disable this correction for applications like tank weighing, batching, filling etc.
to prevent incorrect zeroing during feeding. Refer to Automatic Zero Tracking parameter [204]. 7.4.1.5
The Automatic zero point correction range is limited together with zeroing range above in the parameter
[203] 7.4.1.4 .
6.2.2 Taring
Taring is performed to deduct the initial weight of a container and its contents and to just display the net
weight added into the container or unloaded from the container. The PT210 is programmable for 3
types of tare function: Single tare, Multi-tare, Tare/Clear, see ( 7.3.1.2 , 7.4.1.6 ).
Warning: The tare value cannot exceed the maximum scale capacity. The maximum amount that can
be weighed in NET mode is the difference between the tare weight and the maximum scale capacity.
Capacity in Net = Maximum scale capacity – Tare weight.

◦
Alternatively you can press [TARE] above after placing a container of material on to the
scale. You can remove material from the container and the scale shows how much material
has been taken out.
The tare value is used until either a new tare is set by pressing the [TARE] key or it is cleared
after unloading the scale or zeroing the scale.
Tare/Clear
Place the container on the platform and press the [TARE] key.
The display is zeroed and the NET (net weight) symbol appears.

6.3.7 Setpoints
The PT210 can be set to various basic setpoint functions like absolute, numerical or control outputs.
Refer to 5.11 , 6.2.2.1 and 7.3.3.1 for details. Besides these basic functions you may set digital
outputs so they can easily be used for various applications. This feature of the instrument eliminates the
need for a PLC in control cabinets. Below you will find some examples of the PT210 advanced setpoint
functions. Setpoints are set with a long press of the SP(G/N) key. See 6.1 KEYPAD AND DISPLAY.
Basic setpoints. Below are examples of what could be considered basic setpoint functionality.
Setpoint of absolute indicated weight.
The absolute indicated weight value is compared with the setpoint
entry and the output state is activated if the absolute weight is
higher than the setpoint value. As an example, setpoint 1 is 100 kg
in the drawing on the right. This applied to the indicated weight,
whether net or gross.
Refer to parameter [ 130 ]=1,2,3,4 7.3.3.1
Setpoints of gross weight.
The output state is activated when the gross loading exceeds the
setpoint value. This feature can be used to produce alarm signal
for empty or for overloaded or full scales, tanks etc. As an
example, setpoint 1 is 100 kg in the drawing on the right.
Refer to parameter [ 130 ] 7.3.3.1
www.ptglobal.com
PT210 Instruction Manual
21
Setpoints of real indicated weight.
The + or - sign of the setpoint can be entered. The output signal is
produced if ;
Positive setpoint : The output is activated if the weight is heavier
than the setpoint. Refer to setpoint 1 in the drawing.
Negative setpoint : The output is activated if the negative net
weight is less than the setpoint. Refer to setpoint 2 in the drawing.
As an example, setpoint 1 is 100 kg and setpoint 2 is -200 kg in
the drawing on the right.
To enter the negative or positive value, use a long press of the
<Tare> key while the set point value is seen on the display.
Refer to parameter [ 130 ] 7.3.3.1
Functional setpoint mode enables the PT210 to simulate various control modes such as filling or
checkweighing.
Control Mode-1:
Setpoints are entered such that;
SP1<SP2<SP3<SP4<SP5
and outputs are activated as indicated above.
This mode can be used for check-weighing,
sorting, filling, multi-component batching etc.
Refer to parameter [ 130 ] 7.3.3.1
Example 2: Sorting, grading or Check-weighing. If
you require basic check-weighing or sorting you
can set the setpoints to Control mode-1. After
entering the sorting weights to SP1, SP2 and SP3
in sequence, outputs will change as shown on the
right.
Control Mode-2:
Setpoints are entered such that;
SP1<SP2<SP3<SP4<SP5
and outputs are activated as indicated above.
This mode can be used for filling, grading, checkweighing, sorting, filling, multi-component
batching etc.
Refer to parameter [ 130 ] 7.3.3.1
Example 1: Basic Filling. 3 speed. If you want to
use the weight of the hopper for filling a container
or bag, you can set the setpoints to Control mode2. After entering the coarse, medium and fine
speed cutoff points to SP1, SP2 and SP3 in
sequence, outputs will change as shown above to
fill 20 kg bags.
PT210 Instruction Manual
www.ptglobal.com
Threshold Output: (hysteresis)
2 set point values are entered. SP1 is the point
that the output goes active when the weight
increases past SP1_H. SP1_L is the point that the
output drops to the passive state when the weight
decreases below to SP1_L.
The inverse function is available.
Refer to parameter [ 7-- ] 7.7.1
22
Window Output:
2 set point values are entered. The output is
active when the weight is between SP1_L and
SP1_H. The inverse function is available. Refer to
parameter [ 7-- ] 7.7.1
Example 3: Producing alarm. if you want to
produce alarm signal between two weight values,
e.g. between 200.0 and 300.0 kg, additional to
your other cutoff needs, you can set setpoint 5 to
functional output and active window. After
entering SP5L = 200.0 and SP5H=300.0, the
digital output will be as shown above to control
valves, lamps etc.
6.3.8 Serial Data Output
Serial data output, including printing, is controlled in the interface menus [00_] ( 7.2.1 ), [01_] ( 7.2.2 ).
and [04_] ( 7.2.4 ). The choice of settings is very comprehensive.

Fast Continuous Data Format
Fast continuous “indicated weight” data output can be used only for receiving instruments that can
communicate fast. There is no flow control if the device cannot keep up with the data flow. The output
rate is related to the baud rate. Use higher baud rate for faster data rate. If ASCII codes are received by
the PT210 for the P(print), Z(zero), T(tare) or C(clear) letters, the indicator will act as if the related keys
had been pressed. CR and LF can be enabled in the related parameters.
The data format of the fast continuous data output is;
[STX][STATUS][SIGN][DISPLAYED WEIGHT VALUE][CR][LF]
Examples :
S+000123.4
D+000123.4
+
O
(weight is stable and 123.4)

.
6.3.8.4 BSI Communication
BSI Communication provides conversational access over a Bidirectional Serial Interface. All PT Azure
series products support this convenient communications protocol. It is supported on RS-232C, RS-485
and Ethernet (PT210EN) interfaces.
The BSI data format gives reliable and fast interface advantages for communicating with PLCs or PCs
for process control or transactional applications. This interfacing is recommended especially for PC
interfacing as you can expand your system with additional scales from PT without having to change
your application program base.
The protocol is very simple to use, a command is sent to the PT210 and a response is transmitted
back.
Warning: Only one interface can have BSI enabled at one time. No check sum [CHK] is used over
Ethernet.
General Rules:

(Zeroing is disabled)
Comments:
The Zero command does not work in net weighing.
Weight must be within the zeroing range for all operating modes.
The command will wait up to 2 seconds for scale status to be stable. If stable within this time zeroing
will be performed and Ack. is sent.
If the scale does not become stable within the time out delay, the scale is not tared and Nack. is sent.
Checksum Calculation:
CHK is transmitted as two ASCII characters calculated as below.
Checksum = 0 – (SUM of all response data before CHK)

Example of the calculation of checksums for read stable current weight data.
BSI Example: (CHK is enabled and instrument address is 01)
Command: 01P[CHK][CR][LF]
CHK
= 0 − (0x30+ 0x31+ 0x50)
= 0 − 0XB1
= 0x4F
= Char ‘4’ and ‘F’
Response: 01PS+000123.4[CHK][CR][LF]
CHK
= 0 − (0x30 + 0x31 + 0x50 + 0x53 + 0x2B + 0x30 + 0x30 + 0x30 + 0x31+ 0x32 + 0x33 +
0x2E + 0x34)
= 0 − 0x02B7
= 0x49
= Char ‘4’ and Char ‘9’

Write this command after writing values to 40031-32 addresses.
Only set point low addresses are used if the set point is programmed as standard.
Only 40201 D5 is Output 6 for PT210DIN, unused for outer models.
Programming steps for frequently used communication ……
Reading a weight value:
1. Read 40003,
2. Check D0=0 and D1=1,
3. If yes, read a weight value (gross, net or tare),
4. If D0=1, check D0 until system ready,
5. If D1=0, check the error code.
Zero Calibration procedure:
1. Check the low byte of 40033. It should be decimal '1' before starting adjustment.
2. Load the decimal '188' to 40030 to start Zero calibration.
3. Check the low byte of 40033. During the zero calibration process it is decimal '3'.
4. The low byte of 40033 changes to decimal '1' at the end of Zero calibration.
5. If the low byte of 40033 is '9', check the high byte of 40033 to determine the calibration error.
Span Calibration procedure:
1. Check the low byte of 40033. It should be decimal '1' before starting adjustment.
2. First load the span value to 40031-32 and then load the decimal '220' to 40030 to start Span
calibration.
3. Check the low byte of 40033. During the span calibration process it is decimal '4'.
4. The low byte of 40033 changes to decimal '1' at the end of Span calibration.
5. If the low byte of 40033 is '9', check the high byte of 40033 to determine the calibration error.
Note: For hardware connection details, please refer to the related hardware descriptions in this manual.
Exception codes:
1: Function code is not supported.
2: Out of beginning and ending address range.
3: Invalid value entry or wrong byte number.

The above commands are suitable for Modbus over RS232C and RS485 but for Ethernet are not the
complete Modbus transmissions, they do not include the header. Also as noted above Modbus TCP
over Ethernet has no checksum.
For RS232C and RS485 serial connections a typical complete transmission in hexadecimal is shown
below for device address 01 and including check sum. Neither <CR> nor <LF> should be transmitted.
The command is 0103006300017414 where each pair of digits is hexadecimal for a character.
01 03 00 63 00 01 74 14
01
is the unit identifier (address). Hex 01 = decimal 01.
03
is the function code (read analogue registers)
00 63 is the address of the first register requested, hex 0063 = dec. 99. Address = 40001+99=40100
(for the PT210 this is power supply voltage)
00 01 is the total number of registers to read.
7414 are the checksum characters. Calculating the checksum for the message 010300630001 the
checksum is 0x1474, with low order byte first that becomes 7414.
A typical response shown here in hexadecimal is 01030200EBF80B
Address 01, function 03, data bytes 02, data 00EB, checksum F80B.
Hex 00EB = dec. 235 = voltage 23.5
CHK Checksum:
For RS-232C and RS-485 calculate the checksum, from the address (unit identifier) onwards. The
checksum is a CRC-16 Modbus checksum comprising 2 bytes with the low order byte inserted first.
Consult the Modbus website or use an online CRC generator such as http://www.tahapaksu.com/crc/.
Don’t transmit with a <CR><LF> termination.

7.5.1.1 [300] – Gravity
This parameter should only be used in a scale that will be verified in two stages in different locations by
gravity adjustment (in legal Metrology applications). This parameter should not be touched in other
applications.
The value is the six decimal digits past the decimal point in the acceleration due to gravity value (enter
798564 for 9.798564). If you enter a value in this parameter before calibration, this value will be
assumed as the reference gravity acceleration where the first stage of the calibration performed. After
first calibration this parameter will be zeroed. If the value of this parameter is zero, that means no
gravity adjustment has been performed after calibration.
In the second stage of verification, the gravity acceleration of the place that the weighing instrument will
be used should be entered (as six decimal digits, enter 800065 for 9.800065) and exit programming by
saving the changes without entering the calibration [301].
7.5.1.2 [301] – Calibration
Calibration involves emptying the scale then placing a known calibration weight on an empty platform
and allowing the PT210 indicator to capture values for zero and span. Here calibration weight could
mean a force or pressure of known value. The scale reading must be stable for zero or span calibration
to succeed. If there is vibration or noise, adjust the filter or motion detection to obtain a stable reading
and adjust back to previous values after calibration.
1. Press <PRINT> at the [301] prompt to start the calibration.
2. At the [ZEro.CA] prompt, remove any weight on the platform, then press <PRINT>.
3. The PT210 automatically starts to capture zero and the [WAıt] message displays indicating the
operation is in progress.
4. After the [Load] prompt appears, set the value of the weight used for calibration of the scale,
(seen on the display as [XXXXXX]). If the value of the calibration weight that will be used is
different from the value shown on the display, set the new value with the <TARE> and <ZERO>
keys.
A minimum of 20% of scale capacity is necessary for calibration; PT recommends 50 to 100%.
A calibration error will result if insufficient weight is used.
5. Place the calibration weight on the scale. The weight needs to be a known weight and can be a
load calibrated from another scale.
6. Press <PRINT> to start span calibration and the [WAıt] message displays indicating the
operation is in progress.
7. At the [SAvE] prompt press the <PRINT> key to continue to the next parameter or press the
<f> key to exit without saving the calibration.
7.5.1.3 [302] – Linearity Correction
There may be some non linearity due to the load cell or mechanical scale hardware which could affect
the scale performance. Three step scale calibration in this parameter improves scale performance.
1. Press <PRINT> at the [302] prompt to start the calibration.
2. At the [ZEro.CA] prompt, remove any weight on the platform, then press <PRINT>.
3. The PT210 automatically starts to capture zero and the [WAıt] message displays indicating the
operation is in progress.
4. After the [Load 1] prompt appears, set the value of the weight used for the first step of
calibration of the scale, (seen on the display as [XXXXXX]). If the value of the calibration
weight that will be used is different from the value shown on the display, set the new value with
the <TARE> and <ZERO> keys.
PT recommends 35 to 65% of the scale capacity.
5. Place the calibration weight on the scale. The weight needs to be a known weight and can be a
load calibrated from another scale.
6. Press <PRINT> to start span calibration and the [WAıt] message displays indicating the
operation is in progress.
7. After the [Load 2] prompt appears, set the value of the weight used for the second step of
calibration of the scale, (seen on the display as [XXXXXX]). If the value of the calibration
weight that will be used is different from the value shown on the display, set the new value with
the <TARE> and <ZERO> keys.
PT recommends 90 to 100% of the scale capacity.
8. Place the calibration weight on the scale. The weight needs to be a known weight and can be a
load calibrated from another scale.
9. Press <PRINT> to start span calibration and the [WAıt] message displays indicating the
operation is in progress.
10. At the [SAvE] prompt press the <PRINT> key to continue to the next parameter or press the

These parameters require the settings DIP switch to be ON. The zero and span can independently be
adjusted here.
7.5.2.1 [310] – Zero Adjustment
This parameter is only used to update the zero level of the scale to prevent incorrect weighing from
zero drifts. If this adjustment is required it may indicate a mechanical, wiring or load cell fault. Check
first.
1. Press <PRINT> at the [310] prompt to start the zero adjustment.
2. At the [ZEro.CA] prompt, remove any weight on the platform, then press <PRINT>.
3. The PT210 automatically starts to capture zero and the [WAıt] message displays indicating the
operation is in progress. The scale load must be stable.
4. At the [SAvE] prompt press the <PRINT> key to continue to the next parameter or press the
<f> key to exit without saving the calibration.
7.5.2.2 [311] – Span Adjustment
This parameter lets you to perform span adjustment without zero adjustment. Empty the scale before
starting.
1. Press <PRINT> at the [311] prompt to start the span adjustment.
2. Set the value of the weight used for calibration of the scale, (seen on the display as
[XXXXXX]). If the value of the calibration weight that will be used is different from the value
shown on the display, set the new value with the <TARE> and <ZERO> keys.
A minimum of 20% of scale capacity is necessary for calibration; PT recommends 50 to 100%.
A calibration error will result if insufficient weight is used.
3. Place the calibration weight on the scale. The weight needs to be a known weight and can be a
load calibrated from another scale.
4. Press <PRINT> to start span calibration and the [WAıt] message displays indicating the
operation is in progress. The scale load must be stable.
5. At the [SAvE] prompt press the <PRINT> key to continue to the next parameter or press the
<f> key to exit without saving the calibration.
7.5.2.3 [312] – Span Adjustment Loaded
This parameter is used to perform span adjustment of a scale without needing to empty or remove the
load on it. This operation is especially useful for span adjustment for filled tanks or silos.
Note: You can complete span adjustment without emptying the tank.
Note: The calibration load + the load already on the scale should not exceed the scale capacity.
1. Press <PRINT> at the [312] prompt to start span adjustment under load.
2. The [ P.ZEro] prompt appears on the display to indicate the current scale load will be
determined to be a temporary zero.
3. Press the <PRINT> key and the display will show the [WAıt] message while aquiring temporary
zero. The scale load must be stable.
4. After the [Load] prompt appears, set the value of the weight used for calibration of the scale,
(seen on the display as [XXXXXX]). If the value of the calibration weight that will be used is
different from the value shown on the display, set the new value with the <TARE> and <ZERO>
keys.
A minimum of 20% of scale capacity is necessary for calibration; PT recommends 50% or
more.
A calibration error will result if insufficient weight is used.
5. Place the calibration weight on the scale. The weight needs to be a known weight and can be a
load calibrated from another scale.
6. Press <PRINT> to start span calibration and the [WAıt] message displays indicating the
operation is in progress. The scale load must be stable.
7. At the [SAvE] prompt press the <PRINT> key to continue to the next parameter or press the
<f> key to exit without saving the calibration.
7.5.2.4 [313] – vCal
VCal has some limitations but is a very good way to get a weighing system up and running that can
later be fine tuned with zero and span adjustments above or by adjusting the vCal input parameters.
Warning: The scale capacity and division [212] ( 7.4.2.2 ) must be entered before performing vCal.
Warning: vCal is theoretical calibration by calculation without taking into account external influences.
Corner adjustments, as in a summing box, will make the calibration incorrect. Lengthening or
shortening load cell 4 wire cable connections, variations in gravitational accelleration (g), mechanical
influences and structure geometry variances can all reduce the accuracy of vCal.
This parameter lets you to perform calibration without using any calibration weights. The PT210
www.ptglobal.com
PT210 Instruction Manual
46
coefficients are adjusted in production to increase vCal accuracy, but calibration with a known
calibration load is still the most accurate form of calibration. The calibration coefficients are calculated
from scale capacity, total load cell capacity, load cell full scale output, and estimated dead load.
Note: For better accuracy and if the conditions permit, you may perform automatic zero adjustment
instead of entering estimated preload for a more accurate zero.
1. Press the <TARE> key at the [313] prompt to start vCal.
2. After the [LC.CAP] prompt appears, set the value of the total load cell capacity, (seen on the
display as [XXXXXX]). If the value of the capacity is different from the value shown on the
display, set the new value with the <TARE> and <ZERO> keys.
Warning: Enter the load cell capacity using the same units set in calibration [214] 7.4.2.3 .
Note: Total load cell capacity is the load cell capacity times the number of load cells for a full
load cell system. Where load cells are not installed on all legs of a vessel (hinges are used)
total load cell capacity is the capacity of one load cell X the number of support points.
Example: If the weighing system has 4 pcs. 1000kg load cell, enter 4000.
3. Press the <PRINT> key to go to the next step.
4. After the [LC.oUt] prompt appears, set the value of the average load cell signal output (mV/V)
at it's capacity, (seen on the display as [XXXXXX]). If the value of the output is different from
the value shown on the display, set the new value with the <TARE> and <ZERO> keys.
Note: The load cell output (sensitivity) can be found on the load cell certificates.
Example: If load cell outputs are LC1: 2.0010, LC2: 1.9998, LC3:1.9986 and LC4:2.0002, the
average value will be Mean of LC outputs = (2.0010 + 1.9998 + 1.9986 + 2.0002) ÷ 4 = 1.9999
mV/V
5. Press the <PRINT> key to go to the next step. The indicator shows [ZEr.AdJ].
6. If the scale is empty and you want to use automatic zero calibration instead of entering an
estimated dead load (see next step), press the <PRINT> key. When the prompt [ZEro.CA]
appears ensure the scale is empty and stable and press the <PRINT> key to start zero
calibration, the [WAıt] message displays indicating the operation is in progress. If the prompt
[SAvE] shows, press the <PRINT> key. Not all software versions show the prompt.
7. If the scale is not empty or you prefer to enter an estimated preload value, press the <G/N>
key.
8. After the [PrE-Ld] prompt appears, set the value of the estimated dead load on the load cells,
(seen on the display as [XXXXXX]). If the value of the dead load is different from the value
shown on the display, set the new value with the <TARE> and <ZERO> keys. Press the
<PRINT> key to continue. If the prompt [SAvE] shows, press the <PRINT> key. Not all
software versions show the prompt. Press the <f> key to exit without saving.
Warning: vCal of the zero by entering the dead load (8 above) does not take into account the zero
offset of the load cells. It is possible to adjust the value entered at the [PrE-Ld] prompt to account for
this.
Note: If you want to make zero adjustments after entering an estimated preload value, empty the scale
and change the preload value to (previous estimated value + display value with empty scale) or enter
parameter [310] 7.5.2.1 for zero adjustment.
7.5.3 [32_] – #Adjustment with Coefficients

AzCom installation needs a restart every time. How can I install it?
− Read and follow the installation notes in the installation directory.
− Update your computer (visit http://update.microsoft.com).
AzCom could not connect to the instrument. What can I do?
− Check the power, data cabling and LED status of the PT210 instrument.
− Check PC port settings.
− Remove other connections. Re-energize the PT210 instrument and then make
connection.
My PC doesn’t have a COM port. How can I connect instrument to my PC?
− You can use an RS-232 / USB converter for serial interfacing via USB port, available from
PT, and select the COM port with in the Connection Settings menu.
My PC has a COM port but I couldn’t see the COM port in the Connection Settings menu.
How can I solve that problem?
− Other software may already be connected to that COM port. Close all applications before
running AzCom.
I need very fast interfacing. What is the response delay time of the PT210?
− The PT210 response delay is a maximum of 4 milliseconds for weight data. Extremely fast
interfacing.
What is the external data update rate of PT210?
− Only continuous data output rate might be called external update rate, which depends on
the baud rate and data length but can be up to 65 readings per second.
How can I check the Ethernet connection?
− The PT210EN can be pinged. Issue the command ping followed by the IP address of the
PT210EN from any computer on the network with the PT210EN. You should see a short
response time.
EtherX is searching but it could not find any instrument over the Local Area Network.
− Check the Exceptions tab in Windows Firewall settings. EtherX should be marked.
− Check the firewall of any Anti-virus program to make sure it is not being blocked.
I have made a crossover connection with the PT210EN but EtherX could not find it.
− Check the Internet Protocol (TCP/IP) Properties in Local Area Connection of Windows.
− IP address and gateway address blocks of the PT210EN and PC should be the same in a
cross over connection.

11 APPENDIX
This section contains information relevant to each specific model of PT210.
11.1
PT210AN/DIN - Analogue
The PT210AN and PT210DIN are programmable to one of 4 – 20mA, 0 – 20mA, 0 – 5V or 0 – 10V
analogue output modes.
The analogue output is automatically adjusted to the weighing range after calibration. The mid value of
the analogue output range is set to represent zero load if bipolar use is configured. Manual analogue
output adjustment is available in parameter group [4--] (see 7.6 ).
The analogue output is in proportion to the gross load on the scale. The analogue output signal
functions as described next.
Under Zero
When the gross indication drops below zero, the PT210AN reduces the
analogue output to 0mA or -4V to indicate the error.
Normal Range
The analogue output will reflect the gross value in the analogue output
as programmed (4 – 20mA, 0 – 20mA, 0 – 5V or 0 – 10V).
Over Range
When the gross value exceeds the high limit, the analogue signal
increases to approximately 24mA or 11V and remains there until the
weight display is no longer blanked or the analogue signal returns to
within range.
The following table indicates the analogue output value when the gross indication is out of the normal
range and when there is any error indication on the display. The error data indicated below can be used
to convey the errors to a connected PLC or computer.

PT210PB - Profibus
The PT210PB is equipped with a connector for Profibus DP-V1.
ROFIBUS Connector pin configuration (DB9F)
The Profibus baud rate of the PT210PB interface is detected automatically. Supported baud rates are
9.6 kbps, 19.2 kbps, 45.45 kbps, 93.75 kbps, 187.5 kbps, 500 kbps, 1.5 Mbps, 3 Mbps, 6 Mbps and 12
Mbps. No ‘baud rate’ setting exists, the data format is Profibus-DPV1.
After programming Profibus related parameters for the PT210PB indicator and disconnection with any
PC programming software such as AzCom, you can begin communication with the instrument. A
sample GSD file is available with the USB drive which is supplied together with the instrument.

Reading a weight value:
1. Check the D12…D15 bits of ‘PT210PB Output to PLC Input 2nd Dword’. If there is no error, read
a weight value (gross, net or tare).
Zero Calibration procedure:
1. Check the low byte of Calibration Status. it should be decimal '1' to start adjustment.
2. Write ‘Adjust Zero Calibration’ command and apply New CMD to start Zero calibration.
3. Check the low byte of Calibration Status, it is decimal '3' during the zero calibration process.
4. The low byte of Calibration Status changes to decimal '1' at the end of the Zero calibration.
5. If the low byte of Calibration Status is '9', check the high byte of Calibration Status to
understand the calibration error.
Span Calibration procedure:
1. Check the low byte of Calibration Status. it should be decimal '1' to start adjustment.
2. Write ‘Adjust Span Calibration’ command after writing test weight values to 1st Dword, then
apply this command with New CMD to start Span calibration.
3. Check the low byte of Calibration Status, it is decimal '4' during the span calibration process.
4. The low byte of Calibration Status changes to decimal '1' at the end of the Span calibration.
5. If the low byte of Calibration Status is '9', check the high byte of Calibration Status to
understand the calibration error.

PT210EI - Ethernet/IP
The PT210EI is equipped for communication using the Ethernet/IP protocol common with Rockwell
Automation/Allen-Bradley control networks. For further information see https://www.odva.org.
Ethernet/IP Connectors (RJ45)
EtherNet/IP interfacing of the PT210EI can be performed via hub, switch or serial bus over two
EtherNet/IP ports.
•
Serial bus connection of instruments. You may connect instruments in series to your
Ethernet/IP bus via the two ports.
•
Star connection. If you connect the instrument to your PLC via hub or switch, you can use
either P1 or P2 port on the instrument. You can change the port, if there is any malfunction on
the port in use.
The EtherNet/IP interface supports 10/100Mbit, full or half duplex operation. An EDS file for two port
EtherNet/IP is available on the USB drive which is supplied together with the instrument or for download
from www.ptglobal.com.
There are 4 announcement

a weight value (gross, net or tare).
Zero Calibration procedure:
1. Check the low byte of Calibration Status. it should be decimal '1' to start adjustment.
2. Write ‘Adjust Zero Calibration’ command and apply New CMD to start Zero calibration.
3. Check the low byte of Calibration Status, it is decimal '3' during the zero calibration process.
4. The low byte of Calibration Status changes to decimal '1' at the end of the Zero calibration.
5. If the low byte of Calibration Status is '9', check the high byte of Calibration Status to
understand the calibration error.
Span Calibration procedure:
1. Check the low byte of Calibration Status. it should be decimal '1' to start adjustment.
2. Write ‘Adjust Span Calibration’ command after writing test weight values to 1st Dword, then
apply this command with New CMD to start Span calibration.
3. Check the low byte of Calibration Status, it is decimal '4' during the span calibration process.
4. The low byte of Calibration Status changes to decimal '1' at the end of the Span calibration.
5. If the low byte of Calibration Status is '9', check the high byte of Calibration Status to

PT210EC - EtherCAT
The PT210EC is equipped for communication using the EtherCAT protocol which is the most widely
adopted and most widely accepted real-time fieldbus protocol. For further information see
https://www.ethercat.org/.
EtherCAT Connectors (RJ45)
EtherCAT interfacing of the PT210EC can be performed via hub, switch or serial bus over two
EtherCAT ports.
•
Serial bus connection of instruments. You may connect instruments in series to your EtherCAT
bus via the two ports.
•
Star connection. If you connect the instrument to your PLC via hub or switch, you can use the
P1 port on the instrument.
The EtherCAT interface supports 100Mbit, full duplex operation. An ESI file for two port EtherCAT is
available on the USB drive which is supplied together with the instrument or for download from
www.ptglobal.com.
There are 4 announcement
LEDs on the instrument to
indicate the interface
status as seen below.

Frequently used programming steps.
Reading a weight value:
1. Check the D44…D47 bits of ‘TxPDO 1 (T_UL1)’.
2. If there is no error, read a weight value (gross, net or tare).
Zero Calibration procedure:
1. Check the low byte of Calibration Status. It should be decimal '1' before starting adjustment.
2. Write ‘Adjust Zero Calibration’ command and apply New CMD to start Zero calibration.
3. Check the low byte of Calibration Status. It should be decimal '3' during the zero calibration
process.
4. The low byte of Calibration Status changes to decimal '1' at the end of Zero calibration.
5. If the low byte of Calibration Status is '9', check the high byte of Calibration Status to determine
6. the calibration error.
Span Calibration procedure:
1. Check the low byte of Calibration Status. It should be decimal '1' before starting adjustment.
2. Write ‘Adjust Span Calibration’ command with writing of test weight values to Low Dword of
RxPDO1 (R_UL1), then apply New CMD to start Span calibration.
3. Check the low byte of Calibration Status. It should be decimal '4' during the span calibration
process.
4. The low byte of Calibration Status changes to decimal '1' at the end of Span calibration.
5. If the low byte of Calibration Status is '9', check the high byte of Calibration Status to determine
6. the calibration error.
