MEP500C7-Packing scale weighing controller instrument & weight indicator
1) LCD/OLED displays in English with a nice interface, easy to control and also with user friendly design.
2) Filling mode can be configured with single hopper or double hopper.
3) Three-level feeding flow control (fast, middle and fine), fine feeding can be configured manual or auto mode.
4) Can pre-save 11 groups of quantitative control parameters.
5) Can be configured several quantitative control operation for one bagging.
6) Various time delay functionality for avoid joggling.
7) Available to select the function of automatic zero-setting (with hopper) and automatic taring (no-hopper).
8) Inputs could be configured as material level detection function.
9) Outputs could be configured as clamping and vibrating (Drop/flag) function.
10) 20 I/O (8 inputs/12 outputs), and the port functions can be programmed (pre-assigned).
11) Input may be normally open or close by user configuration.
12) Can be selected pre-act auto adjustment.
13) Set the packaging batch number so that the machine automatically stops when reaching the preset batch.
14) It has a filling accumulative function, and the result of accumulation can be output from the print output interface.
15) It has a sew mechanism controlling function.
16) It has a non-object calibration function.
17) It has I/O test function so that trouble shooting of the electric circuit.
18) Switching power supply and over-voltage protection circuit are used for adapting to a large power supply variation.
