If the melter is switched on when the
temperature of the tank is 27 C (50 F) or
greater below its assigned setpoint
temperature (cold start condition), the ready
LED will not turn on until the ready delay
(defined when the melter was set up) has
elapsed.
Appendix B, parameter 4
The time remaining on the ready delay (in
minutes) appears in the right display at the
end of every scan cycle. When only one
minute remains in the ready delay time, the
right display counts down in seconds.
Appendix B, parameter 4
You can by-pass the ready delay time by
pressing the Heaters key twice.
The appearance of F4 in the right display
immediately after the melter is switched on
indicates a problem with the melter’s
processor or main board.
Monitor Melter Faults
The appearance of F1 in the right display
immediately after starting the melter indicates
that a hose or gun cordset may be loose or
disconnected.
Section 6, Troubleshooting
The condition of one or more inputs may
prevent the heaters from turning on.
Installing Melter Inputs in Section 3,
Installation
If the seven-day clock feature was set up and
turned on when the melter was last switched
off, the clock will automatically turn on the next
time the melter is switched on.
Function Keys
If a power failure occurs, the melter will restart
in its normal heat-up cycle, even if the heaters
were off or the melter was in standby prior to
the power failure. If the seven-day clock was
on prior to the power failure, the melter will
restart in the mode dictated by the clock
schedule at the time the melter restarts.
