Monitoring the Melter
The melter provides indicators that allow you to:
S Quickly confirm that the melter is operating correctly
S Monitor the actual temperature of the reservoir group and each hose
and gun
S Identify melter faults
S Determine when service is required
The melter automatically determines the number and location of all
hoses and guns that are connected to it. Refer to Melt Plate Operation and
More About Heated Components, earlier in this section, for information about
hose/gun capacity and the 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 setpoint temperature.
The ready LED will not turn on, or will turn off, if any of the following events
occur:
S The ready delay is still counting down.
S The operator or a remote input places the melter in the standby
mode.
S The seven-day clock places the melter in the standby mode.
S There is a fault (the fault LED will turn on).
Refer to Monitor Melter Faults and Using Melter Function Keys later in this
section for information about melter faults and using the seven-day clock and
standby functions. Refer to Appendix B, parameter 4, for information about
the ready delay.
