Instruction Manual

Default is ‘± 100’.
6.3.1.4 Power On Zero
This parameter enables automatic power on zeroing of the instrument. Automatic zeroing is performed
if the total zero drift from the calibrated zero signal is within the selected range of the capacity.
The available power on zeroing windows as a percentage of the scale capacity are;
Disable
± 2%
± 10%
This parameter must be disabled or carefully programmed for silo weighing, tank weighing or automatic
weighing applications to preventing unwanted zeroing at power on when there is material in the scale.
If the weight is not within the power on zeroing range, the instrument is powered on without zeroing.
Default is ‘Disable’. (Not available in Count Mode).
6.3.1.5 Zeroing Range
Zeroing of the scale is performed if the difference between load cell signal value and load cell signal
value at zero calibration is within the selected percentage of the scale capacity. Zeroing can be done by
issuing a zeroing command when the scale is stable.
The available zeroing ranges as a percentage of the scale capacity are;
Disable
± 2%
± 20%
± 40%
Default is ‘± 2%’.
6.3.1.6 Auto Zero Tracking
AZT automatically re-adjusts the scale to zero to compensate fo small deviations around the center of
zero. These may be from thermal effects, small amounts of residue, etc. AZT operates only within the
zeroing range above and is not performed if this range is exceeded.
The available AZT window values are;
Disable
± 0.5e
± 1e
± 3e
This parameter must be disabled or carefully programmed for silo weighing, tank weighing or automatic
weighing applications to preventing unwanted zeroing.
Default is ‘Disable’. (Not available in Count Mode).
6.3.1.7 Tare
If this function is enabled, the weight is tared when the tare command is received. Additional conditions
for taring are positive gross weight and no motion. Multi-taring is possible with the PT113.
Default is ‘Enable’. (Not available in Count Mode).
6.3.1.8 Save Tare at Power Off
If this function is enabled, the tare value is stored at power off and the instrument starts up in Net mode
at power on with the saved tare value.
Default is ‘Enable’. (Not available in Count Mode).
6.3.2 RS-232C Parameter Setup
Note: AzComT automatically connects to the instrument whatever the data format setting. After
AzComT disconnection, the instrument returns to run with the last saved data format.
Note: The RS-232C settings for the PT113EN are under the gateway tab.
Warning
: Disable this interface if it is not used to increase system interfacing performance.
6.3.2.1 RS-232C Data Format
This parameter programs the RS-232C communication port data format. The available data formats
are;
Disable
: No data will be transmitted. Select disable if this port is not used.
Continuous
:
The data is transmitted continuously. Refer to ‘Section 9.1.1.4’ for
details. (Available for PT113MB and PT113EN)
BSI
:
Communicates in BSI data format as a slave. Refer to ‘Section
9.1.1.5’ for details.(Available for PT113MB and PT113EN)
Modbus RTU
High-Low
:
Modbus RTU communication. Refer to Section 9.1PT113MB,
PT113EN - Modbus for details. (Available for PT113MB)
Modbus RTU
Low-High
:
Modbus RTU communication. Refer to Section 9.1PT113MB,
PT113EN - Modbus for details. ( Available for PT113MB)
Default is ‘BSI’.
Warning
: BSI mode can only be active for one port at a time.
6.3.2.2 RS-232C Checksum
The use of a checksum inserted in the transmission data can be enabled or disabled for the BSI and
Continuous data formats. The checksum calculation can be found in the related data format description.
Default is ‘Enable’.
