Description

The automatic catch-weighing instrument is a belt weighing scale designated M2400-IWU-xLC where x represents the number of load cells in the instrument and is intended for dynamic weighing. It consists of an electronic weighing indicator M2400 and a load receptor with 1 or 2 load cells (often designated Inline Weigher) or 4 load cells (often designated MaxiweigherII). The instrument can operate as a price labeller.

Software

The firmware of M2400 is displayed during start up and can also be found in the Main menu/Identity.

The software version is given on the form a.bb-cc where a reflects major changes including the legal software, bb reflects major bug fixes not affecting the legal software and cc reflects minor bug fixes.

Approved firmware versions are 1.01-00 or higher.

The firmware also lists the version of the weighing module. Approved version is 100.

Load cells

Inline Weigher models with one load cell (1LC model) or two load cells (2LC model): Flintec PCB C3

MaxiweigherII with 4 (4LC model) load cells:

Flintec SB6 C3 or other certified load cells with same or better specifications

Sealing Measures

There are two alternative methods for sealing the load cells to the indicator.

• Either:

The load cell serial numbers are stored in a CON protected memory in M2400, the serial numbers can be viewed under Menu / Audit and should be identical to those marked on the load cells,

Or:

access to the load cell connection is physically prevented by sealing the M2400 indicator enclosure with a tamperproof sticker or a wire and plumb seal.

On load receptors using four load cells, the junction box, TB-4, is always sealed by using a tamperproof sticker placed on one of its sides.

There are two alternative methods to protecting the legally relevant parameters.

• Either:

The instrument is secured by two event counters, CAL and CON, which are incremented each time the calibration or sealed configuration parameters are changed. At verification the value of the two event counters is written on a brittle plastic sticker - sealed with a verification mark - next to it. If the value of the CAL or CON differs from the one written at verification time, the seal is broken.

Or:

the access control is set to "Locked" either by switch the DIP switch S2-SEAL to the "ON" position, or by setting the Access control in menu Login to "Locked". When Access control is set to "Locked" no changes can be done to CON or CAL parameters. The Access level "Locked" can only be changed by accessing the S1 push bottom on the PCB. By sealing the M2400 indicator enclosure with a tamperproof sticker or a wire and plumb seal the access level cannot be adjusted without breaking a seal.
