Manual 41-DURABLUE-MA-02
If the melter is switched on when
the temperature of the tank is 27 _C (50 _F)
or greater below its assigned
set-point 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.
Section 4, 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
If the melter is set up for manual pump
activation and parameter 7 (motor off delay)
has been changed from the default, the pump
will not stop until a user-specified amount of
time has elapsed.
Appendix B, parameter 7
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.
Section 4, Using Melter Function
Keys
If a power failure occurs, the melter will restart
in it’s 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.
