Calibrating the Hopper-Empty Sensor
The melter is shipped with the hopper-empty sensor calibrated for standard
PUR adhesive. If recalibration becomes necessary, follow this procedure.
SeeFigure5-3.
1. Operate the melter normally until the reservoir is empty, but leave the
empty foil bag in place in the hopper.
2. Loosen the hopper-empty sensor (1) and move it to the lowest position
on the piston (2).
3. Move the sensor up until its LED illuminates and then secure the sensor
at this location.
