PUR Timer
49 PUR Timer
Description: Control option that d etermines the amount of time that the melt
plate can remain on before it is automatically sh ut off and an
S1Cal warning is displayed.
Value: 10 to 120 minutes
Resolution: 1minute
Default Value: 30 minutes
Format: —
Use: For m ost applications, the melt plate only needs to stay on for
about 10 m inutes to satisfy the need for adhesive in the
reservoir. Accordingly, if the melt plate is on continuously for a
considerably longer time period (such as t he default value of 30
minutes), it is likely t hat adhesive has not been added and the
heaters are on but not in operation or that the melt-on-demand
adhesive sensor is out of calibration. Refer to Calibrating the
Level Sensors in Section 5, Maintenance, if this situation occurs
and the S1Cal warning is displayed.
