4.6 ELECTRICAL OPTIONS
The PT610, PT620 and PT630 have a wide range of electrical options as seen in 2.4 MODELS and
FEATURES and if any option was ordered with the indicator it should already be fitted by the factory.
With the load cells connected, the indicator can be energised and set up and calibrated from the front
panel. Information regarding each option and connections can be found later in the manual.
Connection to the standard serial ports can be made before or after initial energising, configuration or
calibration or as detailed in 4.10 SERIAL PORT CONNECTION after de-energising the instrument.
4.7 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.
4.8 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 6 SYSTEM CONFIGURATION AND
SETUP. The scale must also be calibrated to display the weight correctly as detailed in 6.6.
Note
:
PT have AzComIA PC software available to simplify setup and calibration.
Warning
:
If the scale has certification seal, call a person with authorisation before modifying the scale
or settings.
Note
:
It is also possible to calibrate the indicators over fieldbus for instruments with fieldbus
connectivity.
To access configuration and calibration settings there is a DIP switch on the main board near the load
cell connector DIP switch one should be set to position (ON, away from the 1) to change the
metrological related parameters including calibration. DIP switch 2 should not be changed.
4.8.1 PROGRAMMING
Program the instrument according to the needs of your application in this step.
•
Set interface parameters in block
[00-]
(6.2.1), RS232 and RS485 serial ports in
[01-]
.
•
Set configuration parameters in block
[2--]
(6.3) 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--]
(6.3). 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 also have to set any
related parameters. Refer to (6.4.5) (6.4.6) for digital input/output, (6.7) for analogue output
programming and (6.2) for fieldbus interfacing.
Warning:
The programming and parameter descriptions are referred to later. We recommend you save
these parameters before the next step in case the settings are lost if calibration fails due to an error.
4.8.2 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
AzComIA or fieldbus (including RS-232C ()).
•
Full calibration via keys on the instrument by using calibration weights. (6.6.1).
•
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
