VA802EX explosion-proof controller description
Functions and features:
■Dual monitors display other information such as instantaneous weight and target weight or actual packaging results.■Conversion rate up to 200 times/second
■Display accuracy up to 1/60,000
■14 LED segment code display, 8 LED status indicators.
■All metal shielding shell, strong anti-interference ability.
■Small and powerful. Provide complete material filling control, reduction control function.
■All parameters are input through the panel key, all have power off protection function, and configure password limit range.
■Automatic zero tracking range setting
■Automatic selection of tare weight and rezero when starting filling.
■Automatic recognition of tare weight range before filling, there are net weight and gross filling options.
■Each filling has coarse feeding, fine feeding and advance value automatic compensation function.
■Under the ultra - close complement function.
■Using software full digital modulation function, dynamic, static anti - vibration interference combination software package.
■It can store 30 sets of recipes permanently and can be printed as a list.
■Automatic printing, cumulative printing, formula printing.
■Out-of-tolerance automatic alarm, and can choose to suspend the next delay function.
■Date, time, cumulative count has power off protection.
■Advance value auto correction and non - correction selection.
■Output filling data through its own RS-232C communication port.
■Forbid comparing time setting to ensure that the automatic control is not caused by the impact of the scale body error control.
■Through the longest time of slow feeding, the shortest time to adjust the speed of fast feeding closing value, improve the filling speed.
■The filling accuracy can be improved by slow feeding, spot feeding, correction frequency and correction range.
■Rich and easy to connect the input and output terminals can be connected with external controllers to complete a variety of logic control functions.
■The controller has the perfect self-diagnosis function, it has the serial port test, the input port test and the output port test.
■Optional: rs-422 / rs-485 communication module. 4 ~ 20mA or 0 ~ 10V analog output.
