Monitoring the Melter
The melter provides indicators that allow you to:
Quickly confirm that the melter is operating correctly
Monitor the actual temperature of the tank group and each hose
and applicator
Monitor the speed of the motor(s)
Identify melter faults
Determine when service is required
The melter automatically determines the number and receptacle of all
hoses and applicators that are connected to it. Refer to Heated Components,
earlier in this section, for information on identification of heated components.
Confirm that the Melter is Operating Correctly
The ready LED turns on (green) when all of the heated components
are within 3 C (5 F) of their set‐point temperature.
The ready LED will not turn on, or will turn off, if any of the following events
occur:
The ready delay is still counting down.
The operator or a remote input places the melter in the standby
mode.
The seven‐day clock places the melter in the standby mode.
There is a fault (the fault LED will turn on).
Refer to Monitor Melter Faults and Using Function Keys in this section for
information about melter faults and using the seven‐day clock and standby
functions. Refer to Parameter 4 in Appendix B, Operating Parameters, for
information about the ready delay.
Heated components with a set‐point
temperature of zero degrees are skipped
during the automatic scan cycle.
The set‐point temperature of the tank and
the pump cannot be set independently.
The time remaining on the ready delay
appears in the right display at the end of each
scan cycle.
Appendix B, Parameter 4
You can override the seven‐day clock at any
time. If the clock has turned the heaters off,
pressing the heaters key will turn the heaters
back on. If the clock has placed the melter into
the standby mode, pressing the standby key
will return the heated components to their
assigned set‐point temperature.
