VPI-Ultra-DM Weigh Indicator for panel mounting
With firmware for automatic multicomponent dosage
Particular firmware for automatic multicomponent dosage. Particularly designed for industrial automation. Direct management of 12 different components. Depending from the application there are 8 inputs and 16 outputs; the available serial commands enable the automation of many functions in the weighing system.
General main features
- easy to use 25-key waterproof keypad, IP65
- Programmable function keys, for customising the keyboard functions according to the needs
- alphanumeric backlit graphic display with clearly readable data like weight and automation status
- synoptic bar graph with 16 bright indication leds showing the active functions.
- anodised aluminium case according to din standards, 202 x 105 x 148 mm, template for mounting on a board; frontpanel IP65
- time/date and permanent memory data also in case of mains power interruption
- calibration and parameter set-up, configurable from the indicator's keypad; theoretical calibration with entry of the characteristics of the load cells
- up to 10.000e or multirange 3 x 3000e @ 0,3 µv/d CE-M legal for trade
- up to displayable 1.000.000d for internal factory use, internal resolution up to 3.000.000 points
- A/D 24 bit sigma-delta 4-channel conversion, up to 200 conv./sec. with automatic selection; connectable with up to 8 analog load cells with 350 Ω input resistance
- management up to 4 independent scales or digital equalisation of the 4 channels
- exclusive power unit (8 Vdc to 40 Vdc and upon request, 100-240 Vac)
- 2x RS-232/C, 16x 0,5A 48Vac/1A 24 Vdc optoisolated outputs, 8 optoisolated inputs (depending from application and firmware)

Main properties multi component dosage
- firmware for automatic multiple components dosage
- check of the tare presence at dosage start; the tare values are programmable for each recipe
- programmable number of repetitions of the dosage cycle; registration of the consumption
- programmable database of 500 formulas with 16 characters description each, target, flight weight and tolerance; speed change (approximate and fine), minimum and maximum tare
- dual dosage speed (approximate and fine), managed through output active in constant mode or with bleeding function, with programmable ON/OFF time
- quick modification of target weight by preset key
- dosage Start / Pause from keyboard or through activation of the inputs
- automatic printing of the dosage data
- automatic recalculation of the formula targets, by entering the total weight to be dosed
- storage and printing of the consumptions: consumption of each formula, recipe consumption, dosed general total; printouts quickly recallable from keyboard
- automatic correction of the flight weight, with programmable incidence degree
- tolerance test on the dosed weight, with guided correction through simple messages on the display
- (optional) analogue output proportional to the weight or to the dosage speed
- control of the maximum dosage time and alarm management
- alarm indication in display
- management of the dosage on various scales (up to 4 independent), with automatic scale change during the dosage
- completely programmable printouts, for compatibility with any ASCII printer manageable through the serial port; printing of the dosage data, the recipe, consumption and totals' data
