MMI - 2 Belt Scale Note
» When balancing the load cells, a separate test weight is applied to each MSI suspension.
The weights are moved in unison during the balancing procedure.
With the conveyor stopped and locked out, lift the belt off the weighing idlers if possible. Suspend a test
weight on the load cell B side of the scale test weight bar. Ensure Compu-M board B switch SW 1 is in the
CLOSED position.
Except where otherwise indicated in the following
procedure, Compu-M board B switch SW1 must
be kept in the closed position at all times.
