Skirt boards and sealing strips
Sometimes it is necessary to extend the infeed skirt boards and sealing strips the full length of
the conveyor. This can create problems in weighing accuracy if the sealing strips exert excess
force when contacting the belt and indirectly upon the idlers, especially where pinching occurs.
The situation adversely affects the zero calibrations.

Note
If possible, remove skirting in scale area. If not, adjust skirting so sealing strip does not put
excess force on the belt or allow pinching of material.

Load cell handling
The MUS belt scale is designed for low to high-capacity operation and is constructed using two
load cells. Although the load cells are protected by shipping stops that keep the cells from
moving, care should be taken when handling the scale to avoid damaging the cells. The stops
are metal strips about 38 mm long (1.5") for the standard duty, 107 mm long (4.25") for the
heavy duty, with holes at each end for screws. One screw holds the stop to the dynamic section
while the other screw holds the stop to the static section. When handling the MUS during
installation and setup, make sure the stops remain in place. Reinstall both shipping stops during
maintenance or prolonged shutdown.
