Description
DISOMAT® Tersus Weighing Terminal
APPLICATION
The compact DISOMAT Tersus weighing terminal is ideal for a wide range of weighing applications, whether for operating scales, processing data, controlling processes, or communicating with customer systems.
The system includes four predefined configurations for typical applications, which can be easily selected:Cargo scales
- Crane scales
- Filling scales
- Discharge scales
These function variants provide a proven range of functions tailored to each application, with the possibility to adapt the weighing terminal to specific scale requirements.
An optional configuration for use as a road weighbridge (in/out scale) is also available.
The functionality of the DISOMAT Tersus can be adapted to almost any weighing task by configuring the links between logical function blocks. This can be done either using the DISOPLAN PC software (graphical interface) or directly on the terminal, allowing easy and cost-effective local adaptation without extensive programming.
In the optional two-channel measuring version, the DISOMAT Tersus can be used for:
- Twin-unit road weighbridges
- Two-trolley cranes with separate overload monitoring
- Simultaneous monitoring of two silo/bin levels
- Two parallel feeding processes at the same time
EQUIPMENT
The backlit, graphics-compatible QVGA display (320 × 240 dots) continuously shows the weight, even while operators are entering data in the seven-line dialogue area or when status information is displayed.
Displayed information may include:
- Feeding process status (bar graph)
- Input/output status
- Operator guidance and help messages
A special input mode (“telephone alphabet”) allows entry of alphanumeric characters via keyboard.
An optional remote alphanumeric keyboard is also available for more convenient data entry, especially for frequent text input.
A second independent control terminal can be added at any time using another DISOMAT Tersus in mirror configuration.
For control applications, the system provides:
- Up to 8 binary inputs
- Up to 12 binary outputs
- Optional analog I/O module (2 inputs / 2 outputs)
INTERFACES & EXPANDABILITY
You can adapt the functionality of the inputs and outputs to suit application requirements by flexibly linking function blocks.
The number of binary inputs and outputs can be expanded at any time using upgrade modules.
Three serial interfaces allow connection of peripheral devices such as printers and remote displays, as well as communication with data processing systems or PLCs.
An additional serial interface can also be retrofitted if required.
Retrofittable coupling modules are available for the most common industrial fieldbus systems (PROFIBUS, DeviceNet).
An Ethernet interface (100 MBaud) is included as standard equipment.
DISOMAT Tersus features four built-in USB ports for connecting:
- External keyboard
- Legal-for-trade memory
- Printer
MEASURING PERFORMANCE
The DISOMAT Tersus measuring system offers extremely high resolution and outstanding measuring speed, providing large performance reserves even for demanding applications such as:
- Scales with low load cell utilization
- Scales with load sensors installed in hazardous areas
- Fast filling processes
The terminal also performs reliably under extreme temperature conditions, with an operating range of –30 °C to +60 °C.
DATA SECURITY & MAINTENANCE
All scale parameters, including calibration data, are stored in the connector plug (dongle) of the load cell cable.
In the event of a fault, any component can be replaced without recalibration or re-verification. The system immediately resumes operation within legal-for-trade specifications.
(This also applies independently to both channels in the two-channel version.)
The modular system design minimizes downtime and reduces maintenance costs.
HOUSING VERSIONS
- Desk-top unit
- Panel mount unit
- Stainless steel unit
- Field unit
- 19″ mounting rack
These versions provide suitable solutions for virtually all operating environments.
OPERATION & SETTINGS
Standard operating languages are German and English.
Additional languages can be easily loaded using the PC-based DISOPLAN configuration software (Windows application).
Currently available languages include:
- Italian
- Spanish
- French
- Polish
- Czech
- Hungarian
- Russian
DISOPLAN also allows you to:
- Graphically configure function blocks
- Set all device parameters
- Calibrate the scale
- Easily format print layouts
- Record weight curves
- Read out full terminal configuration (backup)
- Restore data to a replacement terminal
DISOPLAN communicates with DISOMAT Tersus via:
- Serial interface
- Ethernet
- Bluetooth (optional)
All parameters and calibration data are stored safely within the terminal and protected against power failure.
The internal real-time clock continues to operate for at least seven days without power.
PRINTING FUNCTIONS
Flexible print formatting allows free layout of weighing reports.
Print vouchers can be graphically designed directly in DISOPLAN with preview.
You can print the following together with weight data:
- Date and time
- Serial number
- Totalized weights
- Number of weighings
- Up to 5 free text fields (max. 25 characters each)
- 3 stored texts (26 characters each)
The print layout is defined via formats, and up to six different print formats can be stored.
They offer the right packaging for virtually every environment.
