Fill Time Limit
The Fill Time Limit or maximum fill time is a user-specified amount of time
that the fill system operates. When the fill system is operating, it activates for
no less than 2 seconds and no more than 10 seconds at a time, then it has a
20 second Off interval. The Fill Time Limit is the sum of all the On times that
occur between the time the system calls f or adhesive and the time the Fill
Time Limit is reached.
If the level sensor is not satisfied by the end of the Fill Time Limit, the control
system generates a fault. When a fill fault occurs, the heaters remain On but
the control system disables the fill system.
For detailed for troubleshooting fill system problems refer to one of the
following manuals:
- ProBlue Flex Adhesive Melter Using the OLED User Interface Manual
