Weight processor PW-310 for the bag accounting system SUM-232

The weight processor PW-310 for the bag accounting system (SUM) ensures an automatic counting of bags of the same type with production, moving by the conveyor, by the weight method (with measuring of the bag mass).

Features:

- control of one-speed or two-position (double-speed) (for filling-up by fast and exact flows) batching mechanism and a gear of the material unloading;

- control of the gears of vibroloading and vibrounloading with individual setting of the start and the end of the operation by the material weight in the hopper;

- external discrete signals of control of the actuators position and allowance of loading and unloading of the material;

- maintenance of the set capacity of the material pass;

- shipment of the set quantity of the material including with the set capacity;

- six- or four-wire connection of the load cell;

- simple calibration of the gear by exemplary weights, and with use of values mV/V of the transmitters;

- an adjustable current output;

- non-volatile memory for storage of the journal, totals, settings and real time clock;

- data transmission to peripherals by interface RS-485 or RS-232 with use of the protocol ModBus;

- remote control of the hopper scales operation from the peripherals by interface RS-485 or RS-232 with use of the protocol ModBus;

- use of wireless data transmission by means of the portable modem;

- the journal of totals (hour, shift, month, annual);

- the journal of events;

- built-in tests;

- indication of abnormal operation of the batcher (emergencies);

- password protection of settings;

- bilingual interface (Russian / English) of the user;

- possibility of loading of the software at the Customer for its renewal or the functionality change.

  • measuring of the bag mass and bags account;
  • stop of the conveyor at passing of the set amount of bags;
  • stop of the conveyor at emergencies in the accounting with shaping of the discrete signal and recording of the emergency type in the joual of events;
  • output of the data about the counted bags on several specialized portable boards;
  • shaping of the data joual for storage of the information about the common total of the account, and also date and time of the recording of this information about the executed processes by maintenance personnel (the process title, date and time), and also records about all emergencies provided in settings.
  • data transmission to peripherals by interface RS-485 or RS-232 with use of the protocol ModBus to the personal computer.
